集成中的反应，原生到现有的Android应用程序

Question

我们正在试图整合反应本土到我们现有的Android应用程序： 我们的build.gradle的SDK要求是： 的minSdkVersion 16 targetSdkVersion 23

我们使用一个Intent调用最初的React index.js：

Intent inte = new Intent(this, ReactNativeStarter.class); 
startActivity(inte); 

其余代码来自反应集成教程。

当我们试图拨打我们的反应成分，我们得到以下错误：

Caused by: java.lang.IllegalAccessError: Method 'void android.support.v4.net.ConnectivityManagerCompat.<init>()' is inaccessible to class 'com.facebook.react.modules.netinfo.NetInfoModule' 
    (declaration of 'com.facebook.react.modules.netinfo.NetInfoModule' appears in /data/data/at.??????/files/instant-run/dex/slice-com.facebook.react-react-native-0.20.1_3762d580ab3ced1fa2f7503493d38e666994b9fa-classes.dex) 
     at com.facebook.react.modules.netinfo.NetInfoModule.<init>(NetInfoModule.java:55) 

你能帮忙吗？

Answer 1

我怀疑这是由gradle这个Maven中allprojects配置拿起反应母语，因为一个错误的道路的错版引起的（至少这是对我们） 见PR here：https://github.com/facebook/react-native/pull/14743
