jna-android callbacks crash about jna HOT 5 CLOSED

That would be part of libffi. win32 and linux have alternate code in place for when special executable memory allocation is required (look for FFI_MMAP_EXEC_WRIT).

When using jna under Android armeabi-v7a, jna callbacks crash when called from native code. Our investigation showed that generated callback proxy code is allocated in heap (which does not have executable permission) and memory protection does not allow such call on some devices. Could you point in which code place could we attempt to fix the issue (so that code is allocated into executable piece of memory) ?

For now fixed in jna-android branch: https://github.com/auris/jna-android/commit/e8328d86af536b3d491c412fd9c4c202ddb156c2 Hopefully jna-android will be integrated into jna tree some day..

twall,

Looks like auris never made a pull request. Can you integrate this fix manually?

this fix was applied by defining the relevant macros in the compiler invocation rather than tweaking the libffi configuration (see native/Makefile). if you're still having callback issues, please raise an issue for it.
