I am trying to add text to button name for example button "ButtonName" be "ButtonNameNow" by button.append("now") that is giving Uncaught Exception
Is there is any example or reason why I am getting this I have searched for example finding nothing also I didn't understand Google documentation about Button append but I have tested it before on Textview
E/UncaughtException: java.lang.IndexOutOfBoundsException
