Answer 1

Unable to find the class names in ADB logs as the names are encrypted. some errors does not have any data about the crashes.(Eg: Input dispatching timeout)

Generally, unlike crashes, there is no useful backtrace in the adb logcat for ANRs.

However, for ANRs, you can pull the /data/anr/traces.txt and find some useful information inside the traces.txt, please refer to Pull anr traces file

Then if you find the stack trace inside the traces.txt is obfuscated, then you can use your mapping file and retrace tool to Retracing stacktraces to analyze the original stack trace.
