Hi @Kanchan-tech1994 thanks for choosing Amplitude!

This is our older Android SDK which is in maintenance and no longer actively maintained.

Could you please upgrade to the latest SDK which likely resolves this issue? Thank you!

hello @justin-fiedler Thanks for your response.

We have updated our SDK as per your suggestion but still getting the same crash occurs.

SDK which we are currently using -> com.amplitude:analytics-android:1.+

Updating SDK doesn't resolve our issue.
