本文介绍在集成环信时遇到的NoClassDefFoundError错误，特别是关于de.greenrobot.event.EventBus类的问题。文章指出这通常与multidex有关，详细解释了在Android 5.0及以下版本中如何正确启用Multidex，包括修改application类的继承以及在gradle文件中进行配置。

集成环信的时候，程序安装运行时报错：

java.lang.NoClassDefFoundError: de.greenrobot.event.EventBus

我认为这个问题在于是multidex，这是因为android 5.0起MultiDex可以启用。设备和模拟器运行5.0操作系统以前的版本，Multidex必须启用方式不同。解决办法：application类中，程序中我们自己的application不继承application类，改为继承MultiDexApplication；如果项目中没有MultiDex，需要在gradle中进行配置，

defaultConfig {
    multiDexEnabled true
}
