What we learn: Service Vibrating the Phone Requires Knowledge: Basic Android To vibrate a phone we need following Permission Do not forget to declare this permission in Manifest. <uses-permission android:name="android.permission.VIBRATE"/> We can Vibrate a Phone Using an Activity  , Service and Using Threads. Using Activity will not be a good Idea because it takes time to vibrate the Phone and an Activity always runs in foreground. We will implement using Service because  a Service runs in Background. for we need to have an Object of Class Vibrator, we do not create the Object directly but we get Vibrate System Service. Vibrator v = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE); Add    <uses-permission android:name="android.permission.VIBRATE"/>  in Your Manifest So let's start. Create a new Android Project  "Vibrate Phone". and edit the manifest and main.xml file <h3>manifest file</h3> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.androidjuncture.vibrate" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" /> <uses-permission android:name="android.permission.VIBRATE"/> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".VibrateMainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>    <service android:name=".VibrateService"/> </application> </manifest> <h3>main.xml</h3> (to be inflated/used in VibrateMainActivity) <div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIwJhE8PxNHRLo0zxJ0DtxDtZcStCT_HlKtlES96q03QsZRlkv-4GR3R02UTy5QRkMovKozwe2lbGHwDsh0De_Qo6QDMRgqwfJxu3rjdGn8O5P-X17awhaOk62Tsd8G5r_4_FxilaG7c9I/s1600/vibrate+main.png"><img alt="" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIwJhE8PxNHRLo0zxJ0DtxDtZcStCT_HlKtlES96q03QsZRlkv-4GR3R02UTy5QRkMovKozwe2lbGHwDsh0De_Qo6QDMRgqwfJxu3rjdGn8O5P-X17awhaOk62Tsd8G5r_4_FxilaG7c9I/s400/vibrate+main.png" width="240"/></a></div> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#99C2D6" android:orientation="vertical"> <TextView android:layout_marginTop="140dp" android:layout_gravity="center_horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="20dp" android:text="Android Vibrate Service Example" /> <Button android:id="@+id/buttonVibrate" android:layout_marginTop="20dp" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Vibrate" /> </LinearLayout> When User clicks on Vibrate Button we will start a new Service which will vibrate the phone. <h3>VibrateMainActivity .java</h3> public class VibrateMainActivity extends Activity @Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); Button btnVibrate=(Button)findViewById(R.id.buttonVibrate); // Set on click listener and start vibrate service when clicked on Button Vibrate btnVibrate.setOnClickListener(new View.OnClickListener() public void onClick(View arg0) // TODO Auto-generated method stub // Create a New Intent and start the service Intent intentVibrate =new Intent(getApplicationContext(),VibrateService.class); startService(intentVibrate); ); <div/> <div/> <div/> <div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgl9umzJzCMYUOiUEIz3BKX003VwZrxqQmMh3x6nhSpPo0My3tD1IfYbJmLAe8XRYVx0h1Hh8G0FsMWyrN7DytKwvJaI4Pl0KhSVg7z6Dv7ohRPty0OnLKZKdkdD-aO_ndxYdYWaP4NKQ18/s1600/phone+vibrating.png"><img alt="" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgl9umzJzCMYUOiUEIz3BKX003VwZrxqQmMh3x6nhSpPo0My3tD1IfYbJmLAe8XRYVx0h1Hh8G0FsMWyrN7DytKwvJaI4Pl0KhSVg7z6Dv7ohRPty0OnLKZKdkdD-aO_ndxYdYWaP4NKQ18/s400/phone+vibrating.png" width="240"/></a></div> <div/> <h3>And The Service Class</h3> Do Not Forget To Declare the Service in Manifest like <service android:name=".VibrateService"/> public class VibrateService  extends Service @Override public void onStart(Intent intent, int startId) // TODO Auto-generated method stub super.onStart(intent, startId); Vibrator v = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE); // pass the number of millseconds fro which you want to vibrate the phone here we // have passed 2000 so phone will vibrate for 2 seconds. v.vibrate(2000); // If you want to vibrate  in a pattern //  long pattern[]=0,800,200,1200,300,2000,400,4000; // 2nd argument is for repetition pass -1 if you do not want to repeat the Vibrate // v.vibrate(pattern,-1); Toast.makeText(getApplicationContext(), "Phone is Vibrating", Toast.LENGTH_LONG).show(); @Override public IBinder onBind(Intent intent) // TODO Auto-generated method stub return null; <h3>Point To Note:</h3>    long pattern[]=0,800,200,1200,300,2000,400,4000 this is pattern in which we want to Vibrate the Phone first 0  means silent for 0 milisecond 800 means vibrate for 800 milisecond 200 means  means silent for 200 milisecond 1200  means vibrate for 1200 miliseconds and So On.</div> </div> Via : <a href="http://www.openandroid.in">OpenAndroid.in</a> Tags : #Source_Code, #Tutorial Orginal Post: <a href="http://www.openandroid.in/vibrate-android-phone.html">How To Vibrate The Android Phone</a>

Android Scheduling Task Using Alarm Manager

Via : <a href="http://www.openandroid.in">OpenAndroid.in</a> Tags : #Downloads, #Source_Code, #Tips__Tricks, #Tutorial Orginal Post: <a href="http://www.openandroid.in/android-scheduling-task-using-alarm-manager.html">Android Scheduling Task Using Alarm Manager</a> <h3 itemprop='name'>Scheduling Task Using Alarm Manager</h3> <div itemprop='articleBody' id='post-body-4467054776181993950'> <div dir='ltr'> <div dir='ltr'> <h2>AlarmManager</h2> Many a times we want some task to be performed at some later time in future. For Example: In SMS Scheduler we want a SMS to be send at some later time, or Task Reminder in which we want to be reminded  about a task at a particular time, to implement all these things we use AlramManager class. <div itemprop='articleBody'/> <div itemprop='articleBody'>AlarmManager class provides access to the system alarm services. These allow you to schedule your application to be run at some point in the future. When an alarm goes off, the <code><a href="http://developer.android.com/reference/android/content/Intent.html">Intent</a></code> that had been registered for it is broadcast by the system, automatically starting the target application if it is not already running. Registered alarms are retained while the device is asleep (and can optionally wake the device up if they go off during that time), but will be cleared if it is turned off and rebooted.</div> <div itemprop='articleBody'/> The Alarm Manager holds a CPU wake lock as long as the alarm receiver's onReceive() method is executing. This guarantees that the phone will not sleep until you have finished handling the broadcast. Once onReceive() returns, the Alarm Manager releases this wake lock. This means that the phone will in some cases sleep as soon as your onReceive() method completes. If your alarm receiver called <code><a href="http://developer.android.com/reference/android/content/Context.html#startService%28android.content.Intent%29">Context.startService()</a></code>, it is possible that the phone will sleep before the requested service is launched. To prevent this, your BroadcastReceiver and Service will need to implement a separate wake lock policy to ensure that the phone continues running until the service becomes available. <h2>AlarmManager Example</h2> In the example I will schedule an alarm to send SMS at a particular time in future. We have two classes 1: MainAcitvity: in this class, we will schedule the alarm to be triggered at particular time . 2: AlarmReciever: when the alarm triggers at scheduled time , this class will receive the alarm, and send the SMS. AlarmReciever class extends BroadcastReceiver and overrides onRecieve() method. inside onReceive() you can start an activity or service depending on your need like you can start an activity to vibrate phone or to ring the phone Permission Required we need <uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>  permission to use the AlarmManger in our application, so do not forget to declare the permission in manifest file  <h2/> <h3>AndroidManifest file</h3> [code lang="xml"] <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.learnandroideasily.blogspot" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" />               <uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>   <uses-permission android:name="android.permission.SEND_SMS"/> <application android:icon="@drawable/ic_launcher" android:label="Demo App" > <activity android:name=".MainActivity" android:label="Demo App" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>                 <receiver android:name=".AlarmReciever"/> </application> </manifest> [/code] <h3>main.xml</h3> <div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiYRRI1IEmC735DOefBugRAUJ4H9loonsKogLgZlkwnbWGsxODAEAvlS5B8aYjNI327XbsVPZuURr3wijQHMQ-8xs9e76-BNIYMviHVMYvqLgDDjQf9v0BP0dwjneZ5LkBMG1KaG0lJZY_h/s1600/main.png"><img alt="" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiYRRI1IEmC735DOefBugRAUJ4H9loonsKogLgZlkwnbWGsxODAEAvlS5B8aYjNI327XbsVPZuURr3wijQHMQ-8xs9e76-BNIYMviHVMYvqLgDDjQf9v0BP0dwjneZ5LkBMG1KaG0lJZY_h/s400/main.png" width="266"/></a></div> <div/> [code lang="xml"] <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:gravity="center_vertical" xmlns:android="http://schemas.android.com/apk/res/android"> <TextView android:id="@+id/textView1" android:gravity="center_horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Alarm Manager Example" android:textAppearance="?android:attr/textAppearanceLarge" /> <Button android:id="@+id/button1" android:layout_marginTop="25dp" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Schedule The Alarm" android:onClick="scheduleAlarm"/> </LinearLayout> [/code] <h3>MainActivity.java</h3> <div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiY6vFJDy0MbCdf9F5lTb0NiC17-Ovbm6WU0i9EJZfbwfaonGp4nUYAq1fGH7dcf8K5RXKiJEUe3bk-GzNlwAWnD6_sUOJEzYh7AZi1HshmpaehybhGHAyRNDdpsNwtQb3tv0RuG_Se7xK4/s1600/alarm+set.png"><img alt="" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiY6vFJDy0MbCdf9F5lTb0NiC17-Ovbm6WU0i9EJZfbwfaonGp4nUYAq1fGH7dcf8K5RXKiJEUe3bk-GzNlwAWnD6_sUOJEzYh7AZi1HshmpaehybhGHAyRNDdpsNwtQb3tv0RuG_Se7xK4/s400/alarm+set.png" width="266"/></a></div> [code lang="java"] public class MainActivity extends Activity @Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState);

How To Send SMS in Android

Via : <a href="http://www.openandroid.in">OpenAndroid.in</a> Tags : #Source_Code, #Tutorial Orginal Post: <a href="http://www.openandroid.in/send-sms-android.html">How To Send SMS in Android</a> In this tutotial we learn how to send SMS from one device to another. In android we use <a href="http://developer.android.com/reference/android/telephony/SmsManager.html" target="_blank">SMS Manager</a>  class to send a SMS and to perform all activities related to SMS. In android we need  permission to send SMS , we use  "android.permission.SEND_SMS"  permission to send SMS so do not forget to include this permission in manifest file Note: all the permissions must be declared in manifest file. Now create a new Project and start. Editing .xml file Edit your .xml file , add two Edittext and one Button First Edittext to enter the PhoneNumber to whom we have to send the SMS Second EditText to enter  the SMS Body. And A Button to Send SMS.   <div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlAPND2LPkldvMVFYIefQv9zzEOSpCqwLNWr8yt_mEPZJ4H1C2M4V2-Lp3HtvZ0Y675FQbhDIjxbovmCxFsvzaXcYy2Lr6hj3Ohn69iQlMe8fZgGHUWlJEnznj5T4FTROaEQGUCdVCSNQj/s1600/Fig-2.jpg"><img alt="" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlAPND2LPkldvMVFYIefQv9zzEOSpCqwLNWr8yt_mEPZJ4H1C2M4V2-Lp3HtvZ0Y675FQbhDIjxbovmCxFsvzaXcYy2Lr6hj3Ohn69iQlMe8fZgGHUWlJEnznj5T4FTROaEQGUCdVCSNQj/s400/Fig-2.jpg" width="296"/></a></div> [xml] <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_height="wrap_content" android:text="Enter the phone number of recipient" android:text="Enter the phone number of recipient" /> <EditText android:id="@+id/txtPhoneNo" android:id="@+id/txtPhoneNo" android:layout_width="fill_parent" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_height="wrap_content" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Message" /> android:layout_width="fill_parent"android:layout_height="wrap_content"android:text="Message" <EditText android:id="@+id/txtMessage" android:id="@+id/txtMessage" android:layout_width="fill_parent" android:layout_width="fill_parent" android:layout_height="150px" android:layout_height="150px" android:gravity="top" android:gravity="top" /> <Button android:id="@+id/btnSendSMS" android:id="@+id/btnSendSMS" android:layout_width="fill_parent" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_height="wrap_content" android:text="Send SMS" android:text="Send SMS" /> </LinearLayout> <div> <div> [/xml] <div>DO Not forget to add the permission in manifest file, Manifest file should look like</div> <div>[xml]</div> <div> <pre><?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="net.learn2develop.SMSMessaging" android:versionCode="1" android:versionName="1.0.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".SMS" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-permission android:name="android.permission.SEND_SMS"> </uses-permission> <uses-permission android:name="android.permission.RECEIVE_SMS"> </uses-permission> </manifest></pre> </div> </div> [/xml] <h3>Activity File:</h3> <div>[java] </div> <pre>public class SMS extends Activity { <a href="http://www.google.com/search?hl=en&q=allinurl%3AButton+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Button</a> btnSendSMS; EditText txtPhoneNo; EditText txtMessage; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); btnSendSMS = (<a href="http://www.google.com/search?hl=en&q=allinurl%3AButton+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Button</a>) findViewById(R.id.btnSendSMS); txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo); txtMessage = (EditText) findViewById(R.id.txtMessage); btnSendSMS.setOnClickListener(new <a href="http://www.google.com/search?hl=en&q=allinurl%3AView+java.sun.com&btnI=I%27m%20Feeling%20Lucky">View</a>.OnClickListener() public void onClick(<a href="http://www.google.com/search?hl=en&q=allinurl%3AView+java.sun.com&btnI=I%27m%20Feeling%20Lucky">View</a> v) <a href="http://www.google.com/search?hl=en&q=allinurl%3AString+java.sun.com&btnI=I%27m%20Feeling%20Lucky">String</a> phoneNo = txtPhoneNo.getText().toString(); <a href="http://www.google.com/search?hl=en&q=allinurl%3AString+java.sun.com&btnI=I%27m%20Feeling%20Lucky">String</a> message = txtMessage.getText().toString(); if (phoneNo.length()>0 && message.length()>0) sendSMS(phoneNo, message); else Toast.makeText(getBaseContext(), "Please enter both phone number and message.", Toast.LENGTH_SHORT).show(); );  [/java] To send an SMS message, you use the <code>SmsManager</code> class. Unlike other classes, you do not directly instantiate this class; instead you will call the <code>getDefault()</code> static method to obtain an <code>SmsManager</code> object. The <code>sendTextMessage()</code>method sends the SMS message with a <code>PendingIntent</code>. The <code>PendingIntent</code> object is used to identify a target to invoke at a later time. For example, after sending the message, you can use a <code>PendingIntent</code> object to display another activity. In this case, the <code>PendingIntent</code> object (pi) is simply pointing to the same activity (<code>SMS.java</code>), so when the SMS is sent, nothing will happen. If you need to monitor the status of the SMS message sending process, you can actually use two <code>PendingIntent</code>objects together with two <code>BroadcastReceiver</code> objects, like this:  [java]  private void sendSMS(<a href="http://www.google.com/search?hl=en&q=allinurl%3AString+java.sun.com&btnI=I%27m%20Feeling%20Lucky">String</a> phoneNumber, <a href="http://www.google.com/search?hl=en&q=allinurl%3AString+java.sun.com&btnI=I%27m%20Feeling%20Lucky">String</a> message) <a href="http://www.google.com/search?hl=en&q=allinurl%3AString+java.sun.com&btnI=I%27m%20Feeling%20Lucky">String</a> SENT = "SMS_SENT"; <a href="http://www.google.com/search?hl=en&q=allinurl%3AString+java.sun.com&btnI=I%27m%20Feeling%20Lucky">String</a> DELIVERED = "SMS_DELIVERED"; PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0); PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0); //---when the SMS has been sent--- registerReceiver(new BroadcastReceiver() @Override public void onReceive(<a href="http://www.google.com/search?hl=en&q=allinurl%3AContext+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Context</a> arg0, Intent arg1) switch (getResultCode()) case Activity.RESULT_OK: Toast.makeText(getBaseContext(), "SMS sent", Toast.LENGTH_SHORT).show(); break; case SmsManager.RESULT_ERROR_GENERIC_FAILURE: Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show(); break; case SmsManager.RESULT_ERROR_NO_SERVICE: Toast.makeText(getBaseContext(), "No service", Toast.LENGTH_SHORT).show(); break; case SmsManager.RESULT_ERROR_NULL_PDU: Toast.makeText(getBaseContext(), "Null PDU", Toast.LENGTH_SHORT).show(); break; case SmsManager.RESULT_ERROR_RADIO_OFF: Toast.makeText(getBaseContext(), "Radio off", Toast.LENGTH_SHORT).show(); break; , new IntentFilter(SENT)); //---when the SMS has been delivered--- registerReceiver(new BroadcastReceiver() @Override public void onReceive(<a href="http://www.google.com/search?hl=en&q=allinurl%3AContext+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Context</a> arg0, Intent arg1) switch (getResultCode()) case Activity.RESULT_OK: Toast.makeText(getBaseContext(), "SMS delivered", Toast.LENGTH_SHORT).show(); break; case Activity.RESULT_CANCELED: Toast.makeText(getBaseContext(), "SMS not delivered", Toast.LENGTH_SHORT).show(); break; , new IntentFilter(DELIVERED)); SmsManager sms = SmsManager.getDefault(); sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);  [/java] The above code uses a <code>PendingIntent</code> object (sentPI) to monitor the sending process. When an SMS message is sent, the first <code>BroadcastReceiver</code>'s <code>onReceive</code> event will fire. This is where you check the status of the sending process. The second <code>PendingIntent</code> object (deliveredPI) monitors the delivery process. The second <code>BroadcastReceiver</code>'s <code>onReceive</code>event will fire when an SMS is successfully delivered.</div></div> Via : <a href="http://www.openandroid.in">OpenAndroid.in</a> Tags : #Source_Code, #Tutorial Orginal Post: <a href="http://www.openandroid.in/send-sms-android.html">How To Send SMS in Android</a>

How To Handle Incoming Calls in Android

Via : <a href="http://www.openandroid.in">OpenAndroid.in</a> Tags : #Downloads, #Source_Code, #Tutorial Orginal Post: <a href="http://www.openandroid.in/handle-incoming-calls-android.html">How To Handle Incoming Calls in Android</a> <h3><a href="http://www.openandroid.in/wp-content/uploads/2014/01/call-handle.png"><img alt="call handle" class="aligncenter size-full wp-image-735" height="360" src="http://www.openandroid.in/wp-content/uploads/2014/01/call-handle.png" width="679"/></a></h3> <h3>Handle Incoming Calls in Android</h3> In this Post I will describe how to Handle incoming Calls on Android and Reacting to them i.e. receiving, rejecting etc. We  can do this by Activity and by Broadcast Receiver, here we will do using Activity. Permissions: As I mentioned in my earlier posts we require to declare permission in manifest file. For listening and reacting to Incoming calls we need following permissions android.permission.READ_PHONE_STATE   to listen to InComing Calls "android.permission.MODIFY_PHONE_STATE"   to receive Incoming Calls You can learn more about permission  <a href="http://developer.android.com/reference/android/Manifest.permission.html" target="_blank">Here</a>. Add these permissions in your manifest file. Your Manifest file should look like <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.smartdialer" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" /> <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" />  <application android:icon="@drawable/icon" android:label="@string/app_name" > <activity android:name=".HomeActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZ-xoPI9r3EN0eyu3Ky_dcsY0giBJ3frzD37P968KhJ-Um9ohQwXXaOoFaR6okheqgm9dgmb01XR02mScz9TPMjQI0LyTRb7YKFe6PoGzd00Vsx-PW8_TclZfb5EaPUNQt_GXlWRnEODlj/s1600/ringing.png"><img alt="" class="alignleft" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZ-xoPI9r3EN0eyu3Ky_dcsY0giBJ3frzD37P968KhJ-Um9ohQwXXaOoFaR6okheqgm9dgmb01XR02mScz9TPMjQI0LyTRb7YKFe6PoGzd00Vsx-PW8_TclZfb5EaPUNQt_GXlWRnEODlj/s320/ringing.png" style="border: 0px;" width="192"/></a>Activity: We need to use TelephonyManager class and  TELEPHONY_SERVICE.

Use the Intent.ACTION_DIAL Activity action to launch a dialer rather than dial the number immediately. This action starts a dialer Activity, passing in the specified number but allowing the dialer application to manage the call initialization (the default dialer asks the user to explicitly initiate the call). This action doesn’t require any permissions and is the standard way applications should initiate calls. Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:1234567")); startActivity(intent);  Via : <a href="http://www.openandroid.in">OpenAndroid.in</a> Tags : #Downloads, #Source_Code, #Tutorial Orginal Post: <a href="http://www.openandroid.in/handle-incoming-calls-android.html">How To Handle Incoming Calls in Android</a>

Android Project Structure

Via : <a href="http://www.openandroid.in">OpenAndroid.in</a> Tags : #Andoird, #Tutorial Orginal Post: <a href="http://www.openandroid.in/android-project-structure.html">Android Project Structure</a> <h2>Part 0: Getting Started</h2> This series of Android tutorials is meant to help you build the skills and confidence necessary to build real, quality Android apps. This tutorial is for the Java developer just getting started learning Android app development, who is somewhat familiar with Eclipse and has installed the Android SDK and the Android Developer Plugin for Eclipse. If you are not prepared, <a href="http://mobile.tutsplus.com/articles/news/learn-android-sdk-development-from-scratch/">see the previous tutorials in this series</a>. <hr/><h2>Part 1: Create a Basic Hello World App</h2> If you have not created a Hello World app yet, do so now. If you need help with this step, see our previous tutorial <a href="http://mobile.tutsplus.com/tutorials/android/creating-android-hello-world-applications/">Creating Android Hello World Applications</a> to learn how. <hr/><h2>Step 1: Expand the Package Explorer</h2> Within Eclipse in the Java perspective, you should see your project displayed in the Package Explorer pane on the left-hand side of the screen. For the purposes of this tutorial, we have created a simple Hello World app whose project is called BasicHelloWorld. <div><img alt="" data-original-url="http://tuts-authors.s3.amazonaws.com/mobile.tutsplus.com/Shane%20Conder%20and%20Lauren%20Darcey/2012/09/26/Android-project-overview_eclipse-package-explorer.png" src="http://cdn.tutsplus.com/mobile/authors/legacy/Shane%20Conder%20and%20Lauren%20Darcey/2012/09/26/Android-project-overview_eclipse-package-explorer.png"/></div> <hr/><h2>Step 2: Explore the /src Directory</h2> The /src folder contains the Java source files associated with your project. For example, the Activity class called MainActivity.java is stored in this directory under the package name you specified in the Android project wizard. This MainActivity class provides all the application code associated with the Hello World app. You will want to keep these files in source control. <hr/><h2>Step 3: Explore the /gen Directory</h2> The /gen folder contains the Java source files and other code files generated by Eclipse that are associated with your project. Do not edit these files directly. For example, the R.java file is a file generated to link your resource files (as defined in the /res directory structure) for use in your /src Java files. You will not need to keep these files in source control. They are recreated whenever you add resources to your project or recompile your project. Make sure they are always writeable or you will run into problems. <hr/><h2>Step 4: Explore the Android Directories</h2> After the /src and /gen directories, you will see one or more libraries linked to your project. In this example, we are building against Android 4.1, so you see this version of the android.jar file linked to the project. Next, you see that we have also linked an Android Dependency to the Android Support library for backwards compatibility with previous versions of the Android SDK. You will not need to keep these files in source control. <hr/><h2>Step 5: Explore the /assets Directory</h2> The /assets folder contains any uncompiled source files associated with your project. Most files are compiled into your project as resources. However, there are some kinds of files that you want to include in your projects as-is, like GL textures. You will want to keep these files in source control. <hr/><h2>Step 6: Explore the /bin Directory</h2> The /bin folder contains the resulting application package files associated with your project once it’s been built. Package files, or apks, are the deliverable that you actually install onto an Android device. You may want to keep these files in source control, but only if you want to keep the final apks that result from building your application successfully. These files are best kept outside the project source tree, as numbered builds, for use by quality assurance personnel, etc. Additionally, even if they are in source control, you’ll want them writable to avoid problems during compilation. Alternately, you could store them in a separate version tracked location that is accessible to other members of your team. <hr/><h2>Step 7: Explore the /libs Directory</h2> The /libs folder contains any secondary libraries (jars) you might want to link to your app. You will want to keep these files in source control. <hr/><h2>Step 8: Explore the /res Directory</h2> The /res folder contains the resource files associated with your project. All graphics, strings, layouts, and other resource files are stored in the resource file hierarchy under the /res directory. Different types of resources are stored in different directories. For example, graphics are stored under the /drawable directory tag, while strings and other primitives are stored under the /values directory tag. User interface resources are stored in the /layout directory. Special tags often follow the directory tag name to organize resources further by screen type, Android version, and other device details. <div><ins/><ins id='aswift_0_anchor'/></div> You will want to keep these files in source control. <hr/><h2>Step 9: Explore AndroidManifest.xml</h2> The AndroidManifest.xml file is a very important configuration file that your application is required to have. This file is used to specify everything about your application from the app’s name and icon to the Activity class files used and the permissions your application needs to run, among many other details. You will want to keep this file in source control. <hr/><h2>Step 10: Explore proguard-project.txt</h2> The proguard-project.txt file is generated by the Android project wizard. This file is used to configure the ProGuard settings associated with your project. ProGuard is a tool that can be used to help protect your code from software piracy using obfuscation and code optimization. Developers usually edit this file only once their application is sufficiently mature to consider deploying it outside the company–as a beta or for release. To find out more about ProGuard for Android and how it can help keep your app code from being reverse engineered, see the <a href="http://developer.android.com/tools/help/proguard.html">Android docs for Proguard</a>. You will want to keep this file in source control. <hr/><h2>Step 11: Explore project.properties</h2> The project.properties file is generated by the Android project wizard. This file is used to configure the Eclipse project settings. Developers rarely, if ever, need to edit this file directly. Instead, right click on the project in Eclipse, choose properties, and make any changes necessary using the Eclipse UI. You will want to keep this file in source control.
