Question

I’m developing an application in which I want to check like to which power source my device is connected to? I know it is possible by some way but I couldn’t figure it out. Thanks for helping.

Depending on what information you’re after a BatteryManager intent may be more useful.

Make a class extending BroadcastReceiver.

Make an intent filter for Intent.ACTION_BATTERY_CHANGED

registerReceiver

public void onReceive(Context context, Intent intent)
{
   TextView ctl;

   int plugged = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
   switch(plugged)
   {
      case BatteryManager.BATTERY_PLUGGED_AC:
          break;
      case BatteryManager.BATTERY_PLUGGED_USB:
          break;
      default:
          break;
   }
}

Don’t forget to unregisterReceiver when you are done.
