I am a newbie, just started dipping my toe in react-native. The first hello world app did run okay, as I started the second one I am getting this error:

我是一个新手，刚开始接触计算机。第一个hello world应用运行得很好，当我开始第二个应用时，我得到了这个错误:

It looks like your app is now multidex, you can learn mor about here

看起来你的应用程序现在是multidex，你可以在这里了解mor

To solve this, just enable multidexing on build.gradle:

要解决这个问题，只需在build上启用多路复用。

defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
