Calling setUserId with invalid character crashes app

[rkrishnan2012]

Expected Behavior

1. Call amplitude.setUserId("hello@email.com")
2. Expect the app to not crash

Current Behavior

The app crashes with stacktrace:

java.io.IOException: Could not create directory at /tmp/amplitude-identity/$default_instance

Possible Solution

Not really sure.

Steps to Reproduce

Call amplitude.setUserId("hello@email.com") after initializing the Amplitude class.

Environment

• Unity Plugin Version: 1.16.7
• Device: Android Pixel 4 API 32 emulator
• Device OS and Version: Android 12

Actually this issue happens because I imported com.amplitude.core.Amplitude instead of com.amplitude.android.Amplitude. Fixing the import resolved my issue.
