Question:
I have read many questions like this but none of them seemed to address my problem.
The problem lies with:
AlertScreen ad = new AlertScreen(SensorListenerService.this);
in my Service class:
public class SensorListener extends Service implements SensorEventListener {
public int onStartCommand(Intent intent, int flags, int startId) {
startForeground(Process.myPid(), new Notification());
AlertScreen ad = new AlertScreen(SensorListener.this); //problem
ad.show();
return START_STICKY;
}
...
It calls my AlertScreen class:
public class AlertScreen extends AlertDialog {
public AlertScreen(Context context) {
super(context);
}
...
What LogCat has to say:

Could anyone shed some light on the problem?
Answer1:You cannot show Dialogs from a Service context.
I suggest you to open an Activity that actually shows the dialog, or take a look at this answer to learn how to show system alerts.
