Realm conflicts with Crosswalk

Question

in my app I have to use Realm and Crosswalk libs. I have imported Realm from gradle like this:

Project gradle
dependencies {
        classpath "io.realm:realm-gradle-plugin:2.2.1"
    }

//----------------------

App module gradle
apply plugin: 'realm-android'

and Crosswalk app like a separate project ( not from gradle ). And when I run my app it crashes with the following logs:

I/art: Late-enabling -Xcheck:jni

But when I delete Realm notations from gradle Crosswalk runs perfectly... So how can I use both and Realm, and Crosswalk together ?

Answer 1

which ABIs of the Crosswalk are you including with your app?

from the Logcat it seems that your project is trying to look for the arm64 version of Crosswalk library, but it can't find it in your APK.

Realm AAR comes with the following ABIs (arm64-v8a, armeabi-v7a, mips, x86 and x86_64), so when you load the Realm library your device will select the appropriate ABI available, in our case arm64-v8a . I presume your Crosswalk lib doesn't include arm64-v8a ABI, hence the error.
