I have to start my appl

Answer 1

You can use BroadcastReceiver component for this purpose. Using this you can detect various events of your device like booting.

To Detect Booting process you need to give permission in AndroidManifest.xml as below,

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>

Then you need to create a BrodacastReceiver which will handle this,

In the onReceive() method the corresponding BroadcastReceiver would then start the event,

public class MyReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context, WordService.class);
        context.startService(service);
    }
}

Answer 2

Use BroadCastReceiver to receive BOOT_COMPLETED broadcast. This broadcast is thrown in device startup

The receiver will be like

    <receiver
        android:name="ReceiverName"
        android:enabled="true" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

You will need to use the following persmission

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

now in code write a BroadCastReceiver class like

public class ReceiverName extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
          // do startup tasks or start your luncher activity
    }
}
