EasyIncrementalUpdate
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。
如何使用
- 引入jcenter库
implementation 'ren.yale.android:incremetalupdate:1.1.2'
- 代码
boolean ret = EasyIncrementalUpdate.patch(context,"new apk path","patch file")
或者
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'
}
}
原理
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
- 下载server/windows/bsdiff.exe,下载server/windows/bspatch.exe
差分命令
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
差分命令
bsdiff old.apk new.apk patch
合并命令(可以用来测试)
bspatch old.apk new.apk patch
