Failed to Enable AutoFill Service by using Intent in Android O

Question

I used this code for enabling the Enable AutoFill Service.

Intent dialogIntent = new Intent(Settings.ACTION_REQUEST_SET_AUTOFILL_SERVICE);
        startActivity(dialogIntent);

I got the next exception:

FATAL EXCEPTION: main

Answer 1

You're missing the package name in the intent. From the javadoc:

Input: Intent's data URI set with an application name, using the "package" schema (like "package:com.my.app").
