How to force install apps to SD card in Android without ROOT!

Getting Ready:

1. First you have to enable USB debugging on your Android device from Settings > Applications > Development > USB debugging.
2. You need to download and install the latest Android SDK on your computer fromhttp://developer.android.com/sdk/.
3. Install the latest Java SDK.

Tutorial:

1. Extract the package to the folder of your choice [Let's say- C:/android-sdk-windows/], run SDK Manager.exe
2. Close the command / windows command prompt window that opens.
3. In the new window, click on Available Packages to the left. Untick all options you are prompted to download except the USB driver option. Usb driver option will need an additional packages called Android SDK tools revision x(13 as of this time) & android sdk platform-tools revision x(7 as of this time) at the top of the list.
   (Note-If you get an error message at this point, enable “Force https://…” in the Settings.)
   Click on the Install Selected button in the bottom right corner and follow the prompts. )
4. Do not open Samsung Kies. Connect your phone to your computer with a USB-cable. Your OS will prompt you to install new drivers. Choose to install them from the android-sdk-windows/extras/google/usb_driver folder. Do not mount your device; you only need to plug-in the cable.
   (If you don’t see this prompt like me, that means you have USB drivers already installed!! If you are running into problems with USB drivers, install these manually- SAMSUNG USB drivers )
5. Run command prompt in administrator.
   Type in the following after the “>” at each step (without quotations,and including spaces and capital letters)

   cd C:\android-sdk-windows\platform-tools
   adb devices

   A list of devices attached should come

   adb shell

   A $ sign should pop up

   pm setInstallLocation 2

   Another $ should pop up

And you’re done!! Close everything, disconnect phone, reboot & enjoy!!
