I’m constantly hitting Unable to get JNI Environment pointer! error but cannot track down

  • 0

I’m constantly hitting “Unable to get JNI Environment pointer!” error but cannot track down it origins. It’s appearing after garbage collection (it’s no different if I call GC.Collect or garbage collection occurs automatically) and then application crashes. An example log output:

I/monodroid-gc(15423): GC cleanup summary: 92 objects tested - resurrecting 71.
F/Mono.Android(15423): Unable to get JNI Environment pointer!
I/ActivityManager( 2679): Process LuntikAndroid9.LuntikAndroid9 (pid 15423) has
died.

What can cause such an error? I’m trying to reproduce it in self contained code snippet but no luck so far.
