Create changelog file with all notes from GitHub releases.

Right now you can exit from the app by tap on back button and press "Exit now" from showed bottom sheet. Replace this behaviour by exit from the application by double tap.

Feedback message cannot be empty if are you trying to send it.

Right now all icons in this bottom sheets colorized in accent color from Hash Checker app but it's not colors from Lite version.

Create flavors and separate Google Play specific logic (in-app updates) by flavors (in-app updated should be only in googlePlay flavor).

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) 🙊

Expected behavior
No such thing there.

App must only opening from other apps for sharing files but not as default app or similar. Need attention to intent-filter sections in AndroidManifest.xml.

Right now case (upper / lower) selection checking in Settings update but not validating when generated or custom hash values setup in edit fields. For generated hash field set case validation before value insertion, for custom hash field set checks in text input handling.

Implement Rate app dialog from Hash Checker.

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
