在Android ICS上编译react-native分支：java.lang.NoClassDefFoundError：com / facebook / react / uimanager / ReactProp

Question

I'm working on a fork for React-Native with Android ICS support. I have trouble running right now on Android 4.0.3, I am working on Ubuntu 14.04 64bit.

Here is what I have done (according to the following instructions: https://facebook.github.io/react-native/docs/android-building-from-source.html ):

• forked react-native so I had my own
• Added compatibility stuff to start with (link: https://github.com/CodeBuffet/react-native/tree/ics-compat , on the ics-compat branch)
• tested locally on android 4.0.3

After working away some errors I had because of the low version, I came across the following error, and was wondering if you guys knew what it was.

I think it has something to do with the fact that it's trying to look for com/facebook/react/uimanager/ReactProp which doesn't exists in the project (but com.facebook.react.uimanager.annotations.ReactProp does).

Some info:

Why are you trying to introduce support for such an old Android version?

• Because I am making an app whose users are 90% Android ICS users. We already started working in React-Native without knowing this, so now I'm trying to make React-Native compatible with ICS so we dont have this issue anymore.

You may need extra work. Please check https://github.com/facebook/react-native-website/issues/653 and https://github.com/facebook/react-native/issues/22118 .
