gradle project dependency with MultiDex

Question

I have two .aar files that I need to add to my project as dependencies. I imported the projects and did the following and it worked just fine.

dependencies {
    compile project(':zoomcommonlib')
    compile project(':zoomsdk')
}

However, I have added many other libraries and I had to use MultiDex library to support apps over 64K methods

dependencies {
    compile 'com.android.support:multidex:1.0.1'
    compile project(':zoomcommonlib')
    compile project(':zoomsdk')
    compile 'com.google.android.gms:play-services-maps:10.2.0'
    compile 'com.google.android.gms:play-services-location:10.2.0'
    .....
}

Yes, MultiDex is properly setup because I can build the application and run it with no problem.

The problem: When I try to utilize those specific projects, application crashes. Following Log:

From my understanding, those project dependencies are not properly getting added with MultiDex enabled. Is there some configuration that I am missing for project dependencies?

I've also tried the following in my build.gradle file.

dexOptions {
    preDexLibraries = false
}

It seems to have no effect on it. It crashes each time.

Answer 1

The ZoomSDK you have doesn't support 64bit Android, unfortunately. In the mean time, you need to disable the use of 64bit libraries in your app and only support the mentioned framework so it builds in 32bit mode.

Add the following to the build.gradle of the main module of your app:

android {
    defaultConfig {
        ndk {
            abiFilters "armeabi-v7a"
        }
    }
}

From the Zoom forum:

We support only 32 bit libs now. To work on 64 bit devices, you should not use other 64 bit libs ( from other projects or other third party SDK). Android OS can support 32 bit libs on 64 bit devices if you don't have other 64 bit libs in the project
