Android 格式化外置SD卡，出现权限问题

[丨苏幕遮丨]

使用了如下方法
public static int formatStorage(String path) {
IMountService iMountService=getMountService();
int a = -1;
try {
iMountService.unmountVolume(path, true,false);
SystemClock.sleep(4000);
a=iMountService.formatVolume(path);
// int b=iMountService.mountVolume(path);
}catch (Exception e) {
e.printStackTrace();
}
return a;
}

manifest里添加如下权限：
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<uses-permission android:name="android.permission.MOUNT_FORMAT_FILESYSTEMS" />

结果运行时候报错

08-16 16:08:26.170: E/AndroidRuntime(11065): java.lang.SecurityException: Requires android.permission.MOUNT_UNMOUNT_FILESYSTEMS permission

完全不知道怎么办了。。。

对了，那个getMountService()是这样的： public static IMountService getMountService() { IMountService mMountService = null; IBinder service = android.os.ServiceManager.getService("mount"); if (service != null) { mMountService = IMountService.Stub.asInterface(service); } return mMountService; }

好久之前做的啦，都忘了，要不试一下把apk签名。

哥们你解决了这问题没? 我把签名成系统应用了之后，也是做这一段操作，还是不能格式化。能给我讲讲你是怎么解决的吗
