Lower Android requirement to SDK level 8; Initial work in game screen only draws semicircles and stars for later use
Dispose additional resources
Load random game in game screen
Show number of stars according to subdifficulty of problem shown; Minor refactor of drawing in Game Screen
If no difficulty is set, Generator choses a random maximum; In game screen if screen is touched it will generate and load a new problem in the same difficulty and subdificulty as set initially
Make Generator able to generate problemas for any target; Add Generator test for non default target; Show target in game screen
Make user able to select a number in game screen
game screen: Show current score; game screen: Fix input not working after a resize
game screen: Initial work in adding operations in games
game screen: Make initial choice independent of operations; Mark last selected number
game screen: Only mark selected number if that number was previously unused
Fixed solved count; Edit used frame image to make it more visible
game screen: Remove calculus dependencies of top circle section
game screen: update game internal things in controller side
Create a new general listener interface; Make game screen listen for onComplete events
ProblemHelper manages now the current problem
