expo: ExpoKit Android: "Too many classes in --main-dex-list, main dex capacity exceeded"

I want to integrate my own push notification, so I detach my exp project. After detached, Android project build failed.

Error:Execution failed for task ':app:transformClassesWithDexForDev19Debug'. com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Too many classes in --main-dex-list, main dex capacity exceeded

Simulator (Android5.1 API 22) build failed
Simulator (Android6.0 API 23) build success
My sdkVersion is 24.0.0

Try add this, works for me while ./gradlew assembleProdRelease

android {

    dexOptions {
        keepRuntimeAnnotatedClasses false
    }

}

@johhansantana @linzebin @nicoara Hi~ I’ve had few days to solve this problem in expo detached app for android. Please refer to expo forum in link here.

I’ve had someone fixed same problem following what I’ve written here. Hope it helps you people~

Hey there, sorry about the annoyance. For now I think the best thing to do is to use a prod target, or keep targeting a newer version of Android.

Leaving this issue open so we can come up with a better answer.
