Android Gradle构建两次包含jni库

Question

I've been trying to solve a problem about Android build, but couldn't figure out how to solve it. Basically, I am trying to build an Android project using Gradle. It works perfect, but the size of the final apk is 7MB more than when I builded with Eclipse.

When I unzip the apk, I see that the JNI Libs are included twice. Which is different from the Eclipse build that includes it only one time. Here is the paths I can find them in the APK:

• lib/armeabi
• lib/armeabi-v7a
• main/jniLibs/armeabi
• main/jniLibs/armeabi-v7a

In my project, those two files are in:

• android/app/src/main/jniLibs/armeabi
• android/app/src/main/jniLibs/armeabi-v7a

I have two different build.graddle files in:

• android/
• android/app/

None of them contains anything related to the JNI Libs.

To build a release, I use the command:

./gradlew assembleRelease

And everything works fine. I use Gradle 1.10.

I was wondering if someone ever encountered the problem and find a solution to avoid to the JNI Libs to be included twice in the APK.

Thanks :)

Answer 1

Put .so files in...

/src/main/jniLibs/armeabi-v7a /src/main/jniLibs/x86

directories and gradle will correctly package the .so files into the correct app and it won't include the duplicates
