android - How to prevent a shared preference from being clear in setting

Question

I don't want to let Settings clear my app sharedPreference by anyone: is it possible?

Answer 1

hey buddy i found an answer here is a way to prevent data being cleared from Shared Preference

Add android:manageSpaceActivity=".ActivityOfMyChoice" to the application tag of your Manifest like:

    <application android:label="MyApp" android:icon="@drawable/icon" 
                 android:manageSpaceActivity=".ActivityOfMyChoice">

Then instead of "Clear Data", there is a button for "Manage Space" which launches ActivityOfMyChoice

it will call my activity and the Activity is finish at creation :)

public class ActivityOfMyChoice extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        finish();

    }
}

Now you can press the "Manage space" as much as you want! :)

this method works 100% of the time.
