Hey! Is there any way to simulate an ANR that actually gets reported as ANR in `ApplicationExitInfo`  (<https://developer.android.com/reference/android/app/ApplicationExitInfo#REASON_ANR>)?
I wanted to test some ANR reporting but I’m not able to actually reproduce an ANR.
I’ve attempted (all inside an on click):
• `Thread.sleep(60000)`
• `while (true) {}`
•  Deadlocking with a mutex
All of these crash the app but the exit info reason is always something else.
There’s a couple of similar threads on this channel but they didn’t really help me.
Thanks!

No. The best you can do is profile your app and check where your cpu usage is high for a long time.... For instance you may be doing a bunch of IO ( instantiate or read shared preferences or dbs) in the application.onCreate method...

I don't want to fix an ANR, I want to force one to test reporting of ANRs. It just turns out that it's harder to actually do one on purpose than I was expecting :sweat_smile:

A Thread.sleep(10000) in the main thread should be enough...

I've tried that but the ApplicationExitInfo API in Android does not report it as such.
