So I heard you want to slice your apk into several apks based on architecture

And I have a shitty hackish but also incredibly simple solution for you. That's a good thing. Yay!

This is a Bash script to slice a single APK into several ones based on architecture. This will create one package for every single architecture supported by Android: armeabi armeabi-v7a mips and x86. Every package will only contain his corresponding native libraries.

Before getting started

Requirements? Well, quite a lot. And everything must by on your PATH.

• jarsigner: It's usually included with OpenJDK JDK and other JAVA (including Oracle's JAVA) JDKs.
• zipalign: It's included with Android SDK, inside 4.4W build tools. No, this won't be on your PATH. Look for it into the directory sdk/build-tools/android-4.4W/.
• aminc: You will probably have to download this and compile it by yourself. Just grab https://github.com/gregko/aminc/blob/master/AndyManMod/aminc.cpp and compile with g++ aminc.cpp -o aminc. Maybe you'll have to add the following include to avoid compilation errors: #include <stdlib.h>.
• zip, unzip: You will probably have this already in your system.

Invocation!

bash apk-slice-by-arch.sh <originalfile.apk> <keystore> <keyname> <keypass>

• originalfile.apk: This is your multiarch APK.
• keystore: This is the path to your keystore, so we can sign the new APKs.
• keyname: The keyname within your keystore.
• keypass: I even don't know why you are still reading this. Of course this is the keystore password.

If everything is fine (eventually it will), some smaller and quite cuter files will be spanned inside the current folder, named by the original file with the architecture appended at the end.

Credits!

Oh yeah, this was not my idea. This is heavily based on a Windows (eugh) script made by the very same author of aminc. You can find it here: http://stackoverflow.com/questions/19268647/gradle-android-build-for-different-processor-architectures

Cheers gregko, thanks for your work, you definitely saved my day.
