NumberFormatException during DB import

---

Describe the bug After starting the App several times I get a NumberFormatException during the import of the db.

To Reproduce Steps to reproduce the behavior: Build and deploy the App several times via Android Studio. I don’t know if this also happens in the Sample app. The only solution of this is to clear all data of the app.

Expected behavior Don’t crash during db import.

Platform details:

• Device: Huawei P9, Pixel 3a
• OS: Android 7.0, Android 10
• Library Version 2.3.1

@roshanrajaratnam In there are the DB files I copied from the Device File Explorer in Android Studio. The app was in the same error state as described earlier.
