[android]报错：Cannot fit requested classes in a single dex file (# methods: 75683 ＞ 65536)

添加了第三方库运行报错

Cannot fit requested classes in a single dex file (# methods: 75683 > 65536)

解决方法：
在app模块下的build.gradle中添加：multiDexEnabled true

android {
   ...

    defaultConfig {
        ...
        multiDexEnabled true

    }
 }
