I'm trying to update the score using threads so that when the score is greater than or equal to 4 the next level button background is changed.
Here is the code Lylevel1 (Lyrics Level 1)
This activity is trying to change button controls of activity "Levelwho" (group of buttons from level 1 to level 10) so when score of lylevel1 is >= 4 the button's background of lylevel2 is changed automatically. But when I click on lylevel1 button the app crashes. Any help?
Here is the logcat
