a specific byte alignment, relative to the beginning of the file. When installed on a device, ensure that alignment on a 4-byte boundary provides performance optimizations. When aligned, the Android system is able to read files using mmap (), even if they contain binary data with alignment restrictions, rather than copying all the data from the package. The benefit is that the amount consumed by running the application in RAM is reduced.Zipalign-v 4

In my opinion, introducing a physical engine is not necessary, but it can make the game more realistic. Box2d is preferred for physical engines, but it is written in C ++, which is inconvenien
