How to transfer android apps from phone to SD card

Android users did not have opportunity to install apps on to SD card prior to 2.2 (Froyo). In pre-Froyo time, apps were moved to SD Card using another app named 'app2SD'. But this had one limitation, the moved apps were virtually uninstalled from the phone. They were not usable until transferred back to the phone memory. But the app managed this move seamlessly.

Now we are in Froyo era so we actually don't need a third party app to move the apps to SD card. The functionality is built into the system by default. The app - in most cases - gets installed to SD card directly without prompting.

But how can you move an app that is already installed into the phone memory to the SD card?. For this follow this method.

Go to  Settings >> Applications >> Manage Applications. Select the application you want to be transferred from phone to SD card. Tap on the Move to SD card button in Storage section.

Click on move to SD card to move the app

For some apps the Move to SD card button will be greyed out so that you are unable to tap on it . This happens in case of some system apps and those apps for which developers have not enabled the move to SD option. You can see an example below.

  

This file being a live wallpaper needs to be in the phone memory itself to work correctly.

Note: Even if you move an app to SD card some data stays in the phone. This is mostly user specific data like searches, game progress etc.
