It amazes me that there are so many apps that do not have the ability to save data to the SD card or remote server. For those die-hard Angry Birds fans who do not want to buy a new phone or tablet because you are afraid that your Angry Birds progress will not transfer, fear no more. XDA forum user, OstrichSak, has come up with a simple tutorial on how to do it and it is Free.
There are free apps in the Android Market for each version of Angry Birds which you may know about, but apparently there are some additional steps that you need to do to make them work.
1) Install one (or more) of the following apps on both devices:
2) Complete ONE level on the new device (do NOT skip this step or you won’t be able to complete the process successfully) and then create a backup to your device using the app.
3) Install the same app on the old device and create a backup for the same game on the old device. Now you have backups of current progress of the same game on both devices and you need to get the old to the new.
4) Use a file explorer (I like ES File Explorer best out of all of them but some prefer Astro… either will work for this DIY) to locate the folder that was created on the new device which will be named the same as the backup app. Within that folder you will find two files which I think are .bkp or something similar. One is scores and one is something else. You want to delete those two files from the new phone and then copy the same two files from the old phone and place them in the same location on the new phone.
5) Back out, launch the backup app that you installed and select restore.
