Developed with the main intention to automate/batch processing decompiling and recompiling and creating flashable zips, XDA forum member xavierjohn22 has put together an Auto APK Tool specifically for modders, devs and translators.
The tools was initially made when translating MIUI apks and building the language pack, and works with Windows.
It’s as simple as placing all your apks that require decompiling into a folder named _INPUT_APK along with the framework-res apk, and then choosing the relevant menu items to decompile all in one shot and do your edits for all in that one folder, recompile all in one shot, and build usable apks which will output into the _OUT_APK folder.
The tool also builds your signed flashable zip.
For much more detail, and to download the tool, head on over to the forum thread._________
