I need to keep broadcast receiver running all the time after app has been started.
Here is the code that registers this receiver in the application
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new ScreenEventsReceiver();
registerReceiver(mReceiver, filter);
And code for receiver
public class ScreenEventsReceiver extends BroadcastReceiver {
public static boolean wasScreenOn = true;
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
wasScreenOn = false;
Log.d("ScreenEventReceiver", "ON");
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
wasScreenOn = true;
Log.d("ScreenEventReceiver", "ON");
}
}
}
You can use a service
In main app start/stop the service
Intent service = new Intent(context, MyService.class);
context.startService(service);
...
Intent service = new Intent(context, MyService.class);
context.stopService(service);
service
public class MyService extends Service
{
private static BroadcastReceiver m_ScreenOffReceiver;
@Override
public IBinder onBind(Intent arg0)
{
return null;
}
@Override
public void onCreate()
{
registerScreenOffReceiver();
}
@Override
public void onDestroy()
{
unregisterReceiver(m_ScreenOffReceiver);
m_ScreenOffReceiver = null;
}
private void registerScreenOffReceiver()
{
m_ScreenOffReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
Log.d(TAG, "ACTION_SCREEN_OFF");
// do something, e.g. send Intent to main app
}
};
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
registerReceiver(m_ScreenOffReceiver, filter);
}
}
