booster-task-compression

This module is used for assets and resource compression, Booster provides two compression tools, pngquant and cwebp (built-in), which compressor to use as the default depends on the minSdkVersion.

• If specified property booster.task.compression.compressor, then use the specified one
• If minSdkVersion >= 18, then use cwebp
• If 15 <= minSdkVersion <= 17, then use cwebp but only compress opaque images, any image has transparency will be ignored
• If pngquant has been installed, then use pngquant
• otherwise, do not compress any resources

本模块用于对资源进行压缩，Booster 提供了两种压缩工具：pngquant 和 cwebp（内置），选择哪个压缩器作为默认的，这取决于 minSdkVersion
