我的构建

Answer 1

您已启用 "multiDexEnabled true"，很可能您并未将其安装在应用程序 class 中。

这就是你应该做的

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
}

最后扩展应用程序

public class YouApplication extends Application {

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

}
