我也碰到这个问题了，你解决了码

我也遇到了这个问题。ImagePickerProvider找不到，后来发现是我自己的MultiDex初始化的位置不对。我在application的onCreate中执行的MultiDex.install，应该在Application的attachBaseContext中执行的。 希望对你有用。

MultiDex.install应该在Application的attachBaseContext中执行解决了我的问题，大家可以这样试试。

直接继承也可以的，具体看https://developer.android.com/studio/build/multidex.html?hl=zh-CN Application的attachBaseContext是自定义不继承的情况这样。 问题出现是因为多dex情况。
