只需在清单中的name标记下添加application为MultiDexApplication

<application
        ....
        android:name="android.support.multidex.MultiDexApplication"
        ...
</application>

修改

在您的情况下，只需在现有的应用程序标记中添加以下代码段

即可

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