如果你的minSdkVersion設置為21或更高 ，你需要做的就是在app-level build.gradle文件中將multiDexEnabled設置為true ，如下所示：

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

但是，如果您的minSdkVersion設置為20或更低 ，則必須使用multidex支持庫，如下所示：

修改app級build.gradle文件以啟用multidex並將multidex庫添加為依賴項，如下所示：

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

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

像這樣創建一個Application類：

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

在Manifest中添加此應用程序類。

<?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>
