Application crash while hooking String.intern()

[razaina]

Hi Colin

i was trying to hook String.intern() but it made the application crash with a SEGV_MAPERR while doing (*env)->CallObjectMethod(...).

#define SEGV_MAPERR (__SI_FAULT|1) /* address not mapped to object */

The strmon example works properly so I do not understand what's going on.

Below is a screenshot of the crash log from logcat. I highlighted in green my lib that has been injected.

The offset 0x000017bc refers to the line 92.

Do you have an idea of what could cause this?

This solution #8 solved the issue for now.
