Start Activity from Broadcast Recevier

Some time we need to start an Activity from Broadcast Receiver..
how can we achieve this i am going to write step by step.

So lets create a small App to do this things 

-------------------------------------------
App Name: BReceiver2Activity
Package Name: com.sunil
Android SDK: Android SDK 2.2 / API 8
-------------------------------------------

MyReceiver.java

1. package com.sunil;  
2.   
3. import android.content.BroadcastReceiver;  
4. import android.content.Context;  
5. import android.content.Intent;  
6. import android.util.Log;  
7. import android.widget.Toast;  
8.   
9. public class MyReceiver extends BroadcastReceiver {  
10.   
11.  @Override  
12.  public void onReceive(Context context, Intent intent) {  
13.     
14.   Toast.makeText(context, "MyReceiver Started",   
15.     Toast.LENGTH_SHORT).show();  
16.   Log.v("Info Message", "in Broadcast receiver");  
17.   Intent myIntent=new Intent(context,MyActivity.class);   
18.   myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
19.   context.startActivity(myIntent);  
20.  }  
21.   
22. }  

MyActivity.java

1. package com.sunil;  
2.   
3. import android.app.Activity;  
4. import android.os.Bundle;  
5.   
6. public class MyActivity extends Activity {  
7.   
8.  @Override  
9.  public void onCreate(Bundle savedInstanceState) {  
10.   super.onCreate(savedInstanceState);  
11.   setContentView(R.layout.main);  
12.   
13.  }  
14. }  

main.xml

1. <?xml version="1.0" encoding="utf-8"?>  
2. <LinearLayout  
3.  xmlns:android="http://schemas.android.com/apk/res/android"  
4.  android:orientation="vertical"  
5.  android:layout_width="fill_parent"  
6.  android:layout_height="fill_parent"  
7.  android:weightSum="1">  
8.  <TextView  
9.   android:layout_width="fill_parent"  
10.   android:layout_height="wrap_content"  
11.   android:text="@string/hello"  
12.   android:layout_weight="0.14" />  
13. </LinearLayout>  

AndroidManifest.xml

1. <?xml version="1.0" encoding="utf-8"?>  
2. <manifest  
3.  xmlns:android="http://schemas.android.com/apk/res/android"  
4.  package="com.sunil"  
5.  android:versionCode="1"  
6.  android:versionName="1.0">  
7.  <uses-sdk android:minSdkVersion="8" />  
8.   
9.  <application  
10.   android:icon="@drawable/icon"  
11.   android:label="@string/app_name">  
12.   
13.   <activity  
14.    android:enabled="true"  
15.    android:name=".MyActivity">  
16.    <intent-filter>  
17.     <action android:name="com.sunil.MyActivity">  
18.     </action>  
19.    </intent-filter>  
20.   </activity>  
21.   
22.   <receiver  
23.     android:enabled="true"  
24.     android:name=".MyReceiver">  
25.     <intent-filter>  
26.     <action android:name="android.intent.action.BOOT_COMPLETED" />  
27.     </intent-filter>  
28.   </receiver>  
29.   
30.  </application>  
31. </manifest>  

Now Reboot Emulator, Activity will appear on start-up.
