I checked it and it works good but I would really appreciate any critic or advice

Describe the bug The last release added Google Play Core to the app. I'm not sure if it was accidentally dragged in as a dependency (which I hope is the case, as then you'd certainly be interested to get it out again) – or added on purpose?

To Reproduce Steps to reproduce the behavior:

1. run apktool d hash-checker-lite_1.0.8.apk
2. dive into the created directory structure
3. find /com/google/android/play/core
4. Look shocked (or at least pretend) :speak_no_evil:

Expected behavior No such thing there.

Changing System.getenv(KEYSTORE_PATH) to String.valueOf(System.getenv(KEYSTORE_PATH)) solves the problem and makes a successful gradle sync

The same for the other three calls of System.getenv

If you accept this, assign it to me, please
