Create patch file from apks for project Nuwa.

NuwaPatchGenerator

Create patch file from apks for project Nuwa. Note, this project is rewritten from the implementation of patch tools of project AndFix, which claims to open source later on.

How to use?

Setup project first, then execute gradle task by gradlew jar, you will get a jar file patch.jar under your project path/patch/build/libs.

Put your apks in some folder (e.g. apkpath), with a structure like this:

apkpath/
   new.apk
   old.apk

Generate patch file diff.dex by using command line:

java -jar patch.jar apkpath

If you also put patch.jar under the folder apkpath, command line showed above can be simplified:

java -jar patch.jar

Or you can specify apks' path and output file path respectively:

java jar patch.jar -f newApkPath -t oldApkPath -o outPutFilePath

When you finally get the patch file diff.dex, you can rename it to anything you need without extra working of packaging it to a jar file.
