First and foremost, make sure you're running with CheckJNI enabled. It's enabled by default on the emulator but not on the device. You can also try running with "forcecopy" enabled and see if that catches anything. See dalvik/docs/jni-tips.html and dalvik/docs/embedded-vm- control.html (either in the sources or in gitweb). You can try to build your own copy of Dalvik VM from the cupcake sources, install libdvm.so, and then use gdbserver or dig through the symbols with this: http://groups.google.com/group/android-developers/browse_thread/thread/73f89bb8739c24bb/5228e7a5dcfff090 So long as the VM is from the same release you shouldn't run into binary compatibility issues, and since you're only replacing the VM this should work on a real device. Root access required. (Of course, if you can make the problem happen in the emulator it's a bit easier to deal with there.) Note that libraries with symbols are never installed on the device itself. They're generated and stored in a separate directory in the "out" directory, and the tools pull them from there. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
