BroadCast Receiver Active only when activity is running else deactivated

Question

Hi i am using a broadcast receiver for location listening but this broadcast receiver is working only when activity is in foreground else when i am not using this app then receiver is not active here is code of activity onCreate's method where i am registering my broadcast receiver

 PendingIntent proximityIntent = PendingIntent.getBroadcast(getApplicationContext(), i, intent, PendingIntent.FLAG_UPDATE_CURRENT);



locationManager.addProximityAlert(

           latitude, // the latitude of the central point of the alert region

           longitude, // the longitude of the central point of the alert region

           1000, // the radius of the central point of the alert region, in meters

           -1, // time for this proximity alert, in milliseconds, or -1 to indicate no expiration

           proximityIntent // will be used to generate an Intent to fire when entry to or exit from the alert region is detected

      );

IntentFilter filter = new IntentFilter(PROX_ALERT_INTENT+s); 

     registerReceiver(new ProximityAlertReceiver(), filter);

and code for BroadcastReceiver is

public class ProximityAlertReceiver extends BroadcastReceiver {



    private static final int NOTIFICATION_ID = 1000;
    public static final String PREFS_NAME = "MyPrefsFile";


    @Override

    public void onReceive(Context context, Intent intent) {



        String key = LocationManager.KEY_PROXIMITY_ENTERING;
SharedPreferences shared=context.getSharedPreferences(MainActivity.PREFS_NAME,0);


        Boolean entering = intent.getBooleanExtra(key, false);
Double longitude=intent.getDoubleExtra("longitude", 0.0);
Double latitude=intent.getDoubleExtra("latitude",0.0);

Intent in = new Intent(context,AlarmActivity.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
in.putExtra("longitude", longitude);
in.putExtra("latitude", latitude);
Log.i("cont1", shared.getInt("count", 0)+"");
in.putExtra("count",shared.getInt("count", 0));
context.startActivity(in);
}

}

i read some where that register and unregister it in onResume and onPause method respectively but when i unregister it in onPause method then it get unregistered means it will not work i want my broadcast receiver to work for all the time.can you please suggest how to accomplish this.

Answer 1

If you want this works in background then, You need to add broadcast receiver in manifest file with Broadcast receiver class.

like this tutorial http://www.vogella.com/articles/AndroidBroadcastReceiver/article.html

You can use your own "MyReceiver".

Here in this case you dont need to register and unregistered. This will work automatically.

Answer 2

if you want your broadcast receiver to run all teh time, yu need to register it from manifest file. from documentation: You can either dynamically register an instance of this class with Context.registerReceiver() or statically publish an implementation through the tag in your AndroidManifest.xml.

Answer 3

First of you are defined mainfest so app also not running they broadcast receiver work.. so you can handle this type of broadcast using a PackageManager and get package name if is enable or disable you can check and run your brodcast

Answer 4

i think Service class will help you , try to implement .... in background for infinity times and when ever your service will find that something is changed then it will send some broadcast . to you :)
