在Java层中捕获JNI异常

Question

I have an Android application that I'm writing, and it uses a module that runs on the JNI layer. I have no control or knowledge on how the NDK module works, and it sometimes throws an un-handled exception, and my app crashes.

Is there any way to catch those JNI propagating exceptions in the Java layer? Or at least detect when the DNK is going to crash due to an exception?

Answer 1

JNI exceptions propagate to the Java layer. The problem is that they only do so when the JNI method returns. In the meantime it may have perpetrated all kinds of self-harm while in an invalid state due to a prior exception. You need to get hold of the JNI source code and fix it, or complain to the vendor/supplier if you can't.
