`finishActivity` is used to close another activity from current activity, for more info you can check official doc : [finishActivity][1] [1]: http://developer.android.com/reference/android/app/Activity.html#finishActivity%28int%29
So you have to use `finish()` instead of `finishActivity()` for current `Activity`

`finishActivity` is used to close another activity from current - [http://developer.android.com/reference/android/app/Activity.html#finishActivity(int)][1], so just change it to `finish();`
