I am writing an app to move data between the host and the phone. Initially I need to do it by copying files to the SDcard, then mounting the SDCard as host mass storage ( while unmounting it from the phone). And vica-versa.
I am trying to do this using the mount call defined in SYSCALLS.TXT. I make the calls from a JNI C function library, and loadLibrary() etc. AndroidManifest.xml has the uses-permission set up for android.permission.MOUNT_UNMOUNT_FILESYSTEM. The code builds, loads runs, but mount or umount return -1 and errno == 1, which is "Operation Not permitted". It sounds to me like I am close, but missing something. What steps could I be missing. ? Or am I using the mechanism incorrectly ? Or the wrong mechanism? What is android.permission.MOUNT_UNMOUNT_FILESYSTEM used for if not for this ? Can someone help ? thanks -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
