Prevent android from saving and retrieving passwords when typing on EditText

You simply just add one property to your editText view

android:inputType="textPassword|textNoSuggestions"

and you are done.

if it is not working for you there is another alternative solution. You can turn off autofill programmatically.

You can try to this.

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);
        }
    }

If none of the suggestions worked, like with me, try this as a last resort:

android:importantForAutofill="no"

This worked for me https://www.addictivetips.com/android/google-autofill-settings-for-apps-android/

Disabling the autofill from Google, but I did not find how to do it just for my app
