Study android Development notes and android Development notes

Recently, I have focused on the source code of several android projects and have some questions.

1: Why do android client games need to enable n threads, and generally each thread only has I ++;

2: why are many lists not synchronized in the game logic and drawing logic;

3: Why do some standard variables not use volatile;

4: why not use a thread-Safe Container;

5: Although opengl only supports arrays in java, List and Set can be converted into arrays! For the Mao android program, we still insist on using arrays!

6: flash is still a single thread. What does android do with multithreading? Every draw thread is executed once every 30 ms and sleep for 30 ms. Why should the logic execution not be put here, but sleep here!
