Where can I find libc.so inside my APK file?

Question

I'm getting native crashes in Android app.

Crashed: Thread: SIGABRT  0x0000000000000000

I tried to open the APK with zip and go to myapp.zip/lib/arm64-v8a and only found libc++_shared.so inside.

Questions: Where can I get the libc.so? I needed to find the source of crashes

Answer 1

lib.c is a part of Android system, means "bug" is placed on Android OS side, you won't fix this by your APK code. well, you may try to avoid it by using other methods/libs at most

Answer 2

From checking my own device /system, I'm able to find the libc.so. But I'm not sure if they are same even for same phone models.
