Automatically start app on boot from code

I have configured my app to automatically start on boot and it's working but only the first time :/

The manifest

 <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" /> <uses-permission android:name="android.permission.READ_PHONE_STATE"/> <uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" /> <uses-permission android:name="android.permission.SHUTDOWN"/> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.PREVENT_POWER_KEY" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" /> <uses-permission android:name="android.permission.WRITE_SETTINGS" /> <uses-permission android:name="android.permission.REBOOT" /> <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /> <uses-permission android:name="android.permission.DEVICE_POWER" /> <receiver android:name=".autostart" android:enabled="true" android:exported="true"> <intent-filter> <category android:name="android.intent.category.DEFAULT"/> <action android:name="android.intent.action.BOOT_COMPLETED"/> <action android:name="android.intent.action.QUICKBOOT_POWERON"/> <action android:name="android.intent.action.REBOOT"/> <!--For HTC devices--> <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/> </intent-filter> </receiver> 

The autostart

public class autostart 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); Log.d("AutoStart", "AutoStart"); } } 

I restart and shutdown the app with this code :

 public static void Reboot(CaniGPSApplication caniGPSApplication) throws IOException, InterruptedException { Process proc = Runtime.getRuntime().exec(new String[] { "/system/bin/svc", "power", "reboot" }); proc.waitFor(); } public static void Shutdown(CaniGPSApplication caniGPSApplication) throws IOException, InterruptedException { Process proc = Runtime.getRuntime().exec(new String[] { "/system/bin/svc", "power", "shutdown" }); proc.waitFor(); } 

I have no idea why my apps doesn't start the second time. I am working on a GPS device (no screen ...) and my app is in system/priv-app .

Hope someone will have an idea :)
