Android NDK open() device permission denied

Question

In a native call, I\'m trying to open(\"/dev/video4\", O_RDWR) but I get errno EACCES 13 \"permission denied\".

If I run the same code* in an executable

Answer 1

Since you get an error when running your code from an Android Java application, I would guess that you are missing a permission. It's the camera that you are trying to access, if I am not mistaken, so if you add:

to your AndroidManifest.xml, your application should run fine.
