    I have a question about system remount for writing file in /system.
    In application, How can I execute remount action. (not adb)
    I tried bellow commands, but get errno 1 (EPERM : not super user).

    try 1,
    ... Runtime.exec("mount -oremount,rw /dev/block/mtdblock3 /system);

    try 2,
    ... Runtime.exec("su mount -oremount,rw /dev/block/mtdblock3 /system);

    try 3,
    env = "LD_LIBRARY_PATH= .....";
    dir = "/system/xbin"
    ... Runtime.exec("mount -oremount,rw /dev/block/mtdblock3 /system, env, dir);

    Cannot 3rd party apps execute remount command?
    or, Doesn't Android have remount API ?

    I expects good reply.
