ashmem giving [Errno 13] Permission denied

Issue

In my rooted Android device,

jint fd = open("/dev/ashmem",O_RDWR);

gives -1 and fopen results in error 13. I've tried changing the permissions as well with chmod 777, but to no avail.

Any ideas? Thank you for your help.

Solution

Apps targeting Android 10 cannot directly use ashmem (/dev/ashmem) and must instead access shared memory via the NDK’s ASharedMemory class
