Mount rooted Android device system folder with read and write permission (rw)

mount -o remount,rw -t yaffs2  /system

or

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system


We have to make sure we are having su permission before executing this command.

$adb shell

$su

$mount -o remount,rw -t yaffs2  /system

$<do what ever you want with super user permission>

Resoruce String to Resource int value

We can covert String name to Resource intvalue using the below method.

              int resId = getResources().getIdentifier(“<package_name>:<resource_folder>/resource_name”, null,null);

exp: int imageResId = getResources().getIdentifier(“com.example1:drawable/myimage”, null,null);

          <view>.setBackgroundResource(imageResId);
