Android Tutorial => BroadcastReceiver to handle BOOT

Example

Example below shows how to create a BroadcastReceiver which is able to receive BOOT_COMPLETED events. This way, you are able to start a Service or start an Activity as soon device was powered up.

Also, you can use BOOT_COMPLETED events to restore your alarms since they are destroyed when device is powered off.

NOTE: The user needs to have started the application at least once before you can receive the BOOT_COMPLETED action.

AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.test.example" >
    ...
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

    ...

    <application>
        ...

        <receiver android:name="com.test.example.MyCustomBroadcastReceiver">
        <intent-filter>
                <!-- REGISTER TO RECEIVE BOOT_COMPLETED EVENTS -->
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

MyCustomBroadcastReceiver.java

public class MyCustomBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if(action != null) {
            if (action.equals(Intent.ACTION_BOOT_COMPLETED) ) {
                // TO-DO: Code to handle BOOT COMPLETED EVENT
                // TO-DO: I can start an service.. display a notification... start an activity
            } 
        }
    }
}
