Learn Android Development notes

　　Recently focused on several Android project source code, there are a few questions

1: Why Android client game to open n threads, and usually the operation of each thread only i++;

2: Why many lists do not synchronize in game logic and drawing logic;

3: Why some standard variables do not use volatile;

4: Why not use a thread-safe container;

5: Although OpenGL only supports arrays in Java, the list and set can be converted into groups! For the fur Android program or so stick to the array!

6: If Flash is still a single thread, what is Android doing with so many threads? Each drawing thread is 30ms executed once, and then sleep 30ms, why does the logic do not put here, but to be here sleep!
