(Defeat the tribal Java source code. It is a strategy game on the android platform that pays attention to the rhythm and time. Players need to place units to defend or attack enemies based on the rhythm of music. When the life value of local people is 0, players will succeed in the game. The source code file is close to 8M, and the tacit music file in it accounts for a large part. If you want to learn about the use and development of Android mobile games, this source code is worth referring to.)
