集成中的反應，原生到現有的Android應用程序

Question

我們正在試圖整合反應本土到我們現有的Android應用程序： 我們的build.gradle的SDK要求是： 的minSdkVersion 16 targetSdkVersion 23

我們使用一個Intent調用最初的React index.js：

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

其餘代碼來自反應集成教程。

當我們試圖撥打我們的反應成分，我們得到以下錯誤：

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) 

你能幫忙嗎？

Answer 1

我懷疑這是由gradle這個Maven中allprojects配置拿起反應母語，因爲一個錯誤的道路的錯版引起的（至少這是對我們） 見PR here：https://github.com/facebook/react-native/pull/14743
