To run dex in process, the Gradle daemon needs a larger heap. 
It currently has approximately 910 MB. 
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB. 
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties. 
For more information see https://docs.gradle.org/current/userguide/build_environment.html

Answer 1

は、あなたが「真multiDexEnabled」を有効にしていると、おそらくあなたはApplicationクラスでそれをインストールしていない java.lang.NoClassDefFoundError: okhttp3.internal.Util

の手順に従ってください。

この

は、アプリケーション

public class YouApplication extends Application { 

    @Override 
    protected void attachBaseContext(Context base) { 
     super.attachBaseContext(base); 
     MultiDex.install(this); 
    } 

} 

を

android { 
    compileSdkVersion 22 
    buildToolsVersion "23.0.0" 

     defaultConfig { 
      minSdkVersion 14 //lower than 14 doesn't support multidex 
      targetSdkVersion 22 

      // Enabling multidex support. 
      multiDexEnabled true  //You have already did this 
     } 
} 


dependencies { 
    compile 'com.android.support:multidex:1.0.1' // add this in dependencies 
} 

を行い、最後に拡張する必要がありますどのようにされており、これは良いガイドですhttps://developer.android.com/studio/build/multidex.html

Answer 2

あなたのGradleでサポートライブラリのいくつかの宣言を持っています。ビルド。 Hereは、問題の原因を特定するための素晴らしいガイドです。

android { 
    dexOptions { 
     preDexLibraries = false 
    } 
}
