This simple app turns your Android phone into a Bubble Picker Demo App.
This app populates the screen with opaque colored named bubbles that easily bounce around the screen. When selected the character will appear behind the bubble and a Toast message will pop up informing the user of the selection made. Then when selected again the character will disappear and the Toast message will pop up informing the user of the selection made. The bubbles can be easily moved around the screen with the flick of a finger.
This demo uses the 'com.github.igalata:Bubble-Picker:v0.1.1' library to enable this feature demonstrated below.
