First of All, this kind of errors are generally not coding errors rather because of some corrupted files in the base APK which can be clearly seen from the logcat. See the ClassLoader is unable to load a specific class from the base apk file, so the FATAL Exception ClassNotFound occurs.

Solution: Basically, it is not a confirmed solution but worth a try, I have faced similar problems and after searching quite a bit, only reasonable solution that I found is to remove all data and Uninstall the App from device and re-installing it. Though, it is not a confirmed solution.
