Clear general settings

I'm trying to make it so that you can keep the high score and I also need the user to be able to reset / delete their high score. TOAST works, but data is not deleted.

public static final String PREFS_NAME = "MyPrefsFile";
    static SharedPreferences settings;
    static SharedPreferences.Editor editor;

    // When 'back' button is pressed save the highscore to settings     
    editor = settings.edit();// Create a new editor
    editor.putInt("highscore", HighScore); // Storing integer
    editor.commit();


    // When 'Show' button is pressed
    public void showPreferences(View v) {
        int highscore = GameActivity.settings.getInt("highscore", GameActivity.HighScore);
        Toast.makeText( MainMenu.this, "Your Highscore is: " + highscore, Toast.LENGTH_LONG).show();
    }

    //When delete button is pressed
    public void clearPreferences(View V) {
        GameActivity.editor = GameActivity.settings.edit();// Create a new editor
        GameActivity.editor.clear();
        GameActivity.editor.commit();
        Toast.makeText( MainMenu.this,"Highscore has been reset",Toast.LENGTH_LONG).show();
    }

I believe you are just reading this wrong, use this

int highscore = GameActivity.settings.getInt("highscore", 0);


Please note that the second parameter is the default value, the value that is returned if the value of this key is not present in the settings.

You can try this:

settings = getSharedPreferences("MyPrefsFile", 0);
preferences.edit().remove("highscore").commit();


Or you can update sharepreference with 0.

Use below to clear general settings

settings.edit().clear().commit();

Or use below to remove one value from settings

settings.edit().remove("highscore").commit();
