moving apps to my SD card on my Xperia E 4.1.1
Android no longer natively supports moving apps to SD Card.  Some manufacturers that ship phones with SD Card slot (like Samsung, for example) often do include this functionality.  Apparently Sony is not one of these manufacturers, so you will not be able to use your SD Card for app storage with their stock firmware.

If you decide to root your device, you will be able to use apps such as Link2SD to move apps to your SD Card.  Note that you will need to re-partition your SD Card (and re-format it) in a special way to be able to take advantage of this feature.  You will also not be able to easily swap the SD Cards in and out, as it will become an "extension" of your phone's internal memory.
