100 / (float)scale;

Log.d(“BatteryReceiver”, “Battery Degree: ” + batteryPct + “%”); // You’ll be able to set off your low battery alert right here if (batteryPct <= 15)
// Show a notification or carry out an motion
Log.w("BatteryReceiver", "Low Battery Alert!");

// In your Exercise or Service:
BatteryReceiver batteryReceiver = new BatteryReceiver();
IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
registerReceiver(batteryReceiver, filter);

// Don't overlook to unregister the receiver in onDestroy() to forestall reminiscence leaks:
@Override
