Android: BatteryLevel widget not updating
I'm having some problems using RemoteViews. Simply want to make a widget that shows battery level. I've done all other stuffs already.
Here is my class:
public class BatteryLevel extends AppWidgetProvider{
public void onUpdate( Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds ){
context.startService(new Intent(context, BatteryMonitorReceiver.class));
}
public static class BatteryMonitorReceiver extends Service{
private int currentBatteryLevel = 0;
private BroadcastReceiver batteryReceiver = new BroadcastReceiver(){
@Override
public void onReceive( Context context, Intent intent ){
currentBatteryLevel = intent.getIntExtra( "level", 0 );
}
};
@Override
public void onStart (Intent intent, int startId) {
registerReceiver( this.batteryReceiver, new IntentFilter( Intent.ACTION_BATTERY_CHANGED ) );
RemoteViews updateViews = new RemoteViews( getPackageName(), R.layout.main );
updateViews.setTextViewText( R.id.level, String.valueOf(currentBatteryLevel));
ComponentName thisWidget = new ComponentName( this, BatteryLevel.class );
AppWidgetManager manager = AppWidgetManager.getInstance( this );
manager.updateAppWidget(thisWidget, updateViews);
}
@Override
public IBinder onBind( Intent intent ){
return null;
}
}
}When i start the app no error and btw no update at R.id.level.
What's wrong?
Note: api version 7.
Since your service is an inner class, I guess you have not declared it in your Android Manifest, which is needed. And you shouldn't use onStart , it is deprecated. Use onStartCommand . And you forgot to unregister your receiver...
