EasyIncrementalUpdate

English

Android差分补丁库，通过native层合并APK，实现增量更新升级，让你更新的APK更小。

  • 引入jcenter库
implementation 'ren.yale.android:incremetalupdate:1.1.2'

boolean ret = EasyIncrementalUpdate.patch(context,"new apk path","patch file")

String oldApk = EasyIncrementalUpdate.getApkSourceDir(context);
boolean ret = EasyIncrementalUpdate.patch(oldApk,"new apk path","patch file")

可以根据ret的值判断是否成功，如果失败的话，可以全量更新，失败的原因可以看logcat TAG=EasyIncrementalUpdate的日志

  • ndk abi 选择

在app/build.gradle中，请根据自己的需求选择

    defaultConfig {
        ...
        ndk {
            abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'arm64-v8a','mips'
        }
    }

服务器端通过开源差分工具bsdiff实现差分生成patch文件,客户端下载patch文件, 和本地原apk合并生产新的apk

服务器端差分工具使用

windows

bsdiff.exe old.apk new.apk patch

合并命令(可以用来测试)

bspatch.exe old.apk new.apk patch

linux_x86-64

  • 下载server/linux_x86-64/bsdiff,下载server/linux_x86-64/bspatch
bsdiff old.apk new.apk patch

合并命令(可以用来测试)

bspatch old.apk new.apk patch
