ANR: trace information before application be killed
Closed this issue · 3 comments
Is your feature request related to a problem? Please describe.
If ANR occurs, application will be kill by runtime. There is little information to help debug.
Describe the solution you'd like
Before application be killed, trace application status such as CPU, memory, stack trace, etc.
Reference implementation:
https://developer.android.com/topic/performance/vitals/anr
http://androidxref.com/9.0.0_r3/xref/frameworks/base/services/core/java/com/android/server/am/AppErrors.java#885
Describe alternatives you've considered
Add a ANR trigger, such as via system property. When debug, turn ANR off, which would cause application hang and perhaps the scene would be saved.

The android seems always collects these info when ANR at http://androidxref.com/9.0.0_r3/xref/frameworks/base/services/core/java/com/android/server/am/AppErrors.java#993?
