AndroidRuntime：致命异常：PID：8255

Question

When we add Google Analytics into our Android app, the previously worked app shows error with info:

AndroidRuntime: FATAL EXCEPTION: PID: 8255

in the main process. What are the possible reasons it may be caused by?

Moreover, at the time we added Google analytics, we added

implementation 'com.google.firebase:firebase-core:16.0.4'

in the build.gradle under app branch under dependencies , as well as under the main build.gradle branch, we added

classpath 'com.google.gms:google-services:4.0.2'

under dependencies , and

google()

under repositories . We are not sure if they are the reasons for the conflict.

We appreciate any helpful answers.
