如果 minSdkVersion 设置为 21或更高，您需要做的就是将 multiDexEnabled 设置为 true 在您的应用级build.gradle文件中，如下所示：

android {
    defaultConfig {
        ...
        minSdkVersion 21 
        targetSdkVersion 25
        multiDexEnabled true
    }
    ...
}

但是，如果 minSdkVersion 设置为 20或更低，则必须使用multidex支持库，如下所示：

修改app级build.gradle文件以启用multidex并将multidex库添加为依赖项，如下所示：

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 25
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

像这样创建一个Application类：

public class MyApplication extends MultiDexApplication {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }
}

在Manifest中添加此应用程序类。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your package name">
    <application
        android:name=".MyApplication" >
        ...
    </application>
</manifest>
