I have an app that I have recently submitted to the play store. I had tested the .apk file and everything was working fine. On the first install (from the store) – you can login but then it crashes. Here is the stack trace I am getting from the report:

java.lang.NullPointerException

I am just not real sure where to start looking. Any ideas?

    Looks like you used some toole (like Proguard) to obfuscate your code.
    Did you test your APK after obfuscation?

    From the logs above a NullPointerException has occured in your code, you’d need to de-obfuscate your code using the key files generated by the obfuscating tool in order to find out the real place (line of code) where null pointer has been accessed.

    Please Note,
    In the process of obfuscation, sometimes (human error) can cause some of the required methods to be obfuscated. Which in turn causes those methods not to be found, hence an exception (NoSuchMethod) might be raised.
