I made a comprehensive line of slightly more complex today's app, previously acquired knowledge are strings again, and better use of memory.

Today do the project are: basketball scorer.

A team can write, where aliquots team B, the score may be all cleared, operation may be performed once withdrawn, may be localized (i.e., can be run in English and Chinese, without loss of data), it may be cross-screen operation.
