背景是我们打包出来是7z格式的压缩包，最近我在安装里面的包的时候，发现一直安装失败。报错提示这个：
adb install base.apk
$ Performing Push Install
$ base.apk: 1 file pushed, 0 skipped. 0.3 MB/s (11702337 bytes in 33.669s)
$ pkg: /data/local/tmp/base.apk
$ Failure [INSTALL_FAILED_INVALID_APK]
尝试 adb push base.apk /sdcard/download中，手动安装也是提示失败。
file base.apk
base.apk: Zip archive data, at least v0.0 to extract, compression method=deflate
我用jadx打开也是报错。

直到后面我用7z解压压缩包，而不是用mac系统自带的解压（Archive Utility），包才正常。
$ zipinfo ./app/build/channel/platform/base.apk

看着就是Archive Utility解压7z的包，解压之后，0b22ec0 之后的数据出现了丢失，变成了*, 丢失的信息（zip END header）导致jadx解析失败，也导致 adb 安装失败。
