How to Start an Application at Device Bootup in Android
This tutorial will explain to stat an application while the Android device boot-up. For this we need to listen to the BOOT_COMPLETED action and react to it. BOOT_COMPLETED is a Broadcast Action that is broadcast once, after the system has finished booting. You can listen to this action by creating a BroadcastReceiver that then starts your launch Activity when it receives an intent with the BOOT_COMPLETED action.
1. Add this permission to your manifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
2. Create a Custom BroadcastReceiver in your project to receive boot up event
import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class BootReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Intent i = new Intent(context, MainActivity.class); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(i); } }
3. Adding the BroadCastReceiver to the Android Manifest
<receiver android:name=".BootReceiver" android:enabled="true" android:permission="android.permission.RECEIVE_BOOT_COMPLETED" > <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </receiver>
Install the application, and then restart the device. You can see the application will start after the device restarts.
