Another activity is running but it is in
onPauseand you can’t guarantee that activity will not destroy before you going back to there again.So you should better look at
onResumeof the activity to update the button text.If you still want to change the button text while activity is onPause you can use a broadcast receiver on the activity that will change the text.You can also use a handler along with runnable to update button text.
