Android Studio – How to fix AAPT: error: '???dp' is incompatible with attribute layout_marginEnd (attr) dimension

After install of android studio I wanted to create a test app so I added only one button to the default hello world app and run it but I got this error. (after search stackoverflow for similar problem and solution I ask a question……)

AAPT: error: '???dp' is incompatible with attribute layout_marginEnd (attr) dimension. 

here is auto generated code by android studio:
