i don't have any emulator, i testing on my smartphone.

If you're testing on the smartphone, the logcat will contain the exception.

You can run the following command on your computer:
adb shell
And once you are logged into your phone, run this command:
logcat | grep -i exception
You should see many exceptions popping up from other apps. NOW click on your button and see what exception comes pops up in the log.

OR

You can download some kind of logcat viewer for android with filter and filter the output based on the app name or the keyword "exception". But make sure you crash your app AFTER you have opened the logcat to be sure it's getting picked up by whatever viewer you're using.
