Probably the fastest image compression framework on the Android platform.

- Compression speed
Internal use of thread pool scheme to compress tasks, while the necessary memory check.
Under the premise of not OOM, the maximum speed of compression is improved. The common size of 9 pictures is 20M+ and can be processed in 2S.
Of course, the machine performance, the system at the time of memory are affected by this, my test machine is [magic blue Note]…
- Effect of compression
Since the compression strategy is integrated with Luban, the final comparison of image compression size before and after can refer to Luban.
Based on this, I optimized the requirements of long graphs common in social products.
