Currently there is no direct way to disable the autofill for an entire application, since the autofill feature is View specific. You can still try this way and call BaseActivity everywhere. public class BaseActivity extends AppCompatActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); disableAutofill(); } @TargetApi(Build.VERSION_CODES.O) private void disableAutofill() { getWindow().getDecorView().setImportantForAutofill(View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS); } } You … Read more
