Alert dialog from Android service

Question

How do I display dialog from a service?

Answer 1

Another way without using an activity:

AlertDialog alertDialog = new AlertDialog.Builder(this)
                    .setTitle("Title")
                    .setMessage("Are you sure?")
                    .create();

alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.show();

Please note that you have to use this permission:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
