Wallpaper Randomizer for Android
When the app first loads, it will query all the images on your SDCard so it will populate a list.
NOTE:This may take a few seconds depending on how many images are on your phone.
When the list is populated, scroll through and select all the images you want added to your own personal list that the phone will cycle through as it's wallpaper.
As you get more images that you want to add to your personal list, just go back to app and select the images you want.
The "Clear Database" should only be used when you want to start over.
