由于Facebook登录按钮本身可用,我想要一个适用于Android的React Native包装器组件.所以,我试着写它.但应用程序甚至在开始之前就崩溃了.我的github存储库是:https: //github.com/lalith26/react-native-fb-login-android

我做了以下事情:

1. 我为LoginButton facebook小部件创建了Manager:

https://github.com/lalith26/react-native-fb-login-android/blob/master/android/app/src/main/java/com/fbloginbutton2/FBLoginButtonManager.java

2. 我创建了一个扩展MainReactPackage的ReactPackage:

https://github.com/lalith26/react-native-fb-login-android/blob/master/android/app/src/main/java/com/fbloginbutton2/FBLoginButtonReactPackage.java

3. 我在MainActivity中添加了新的ReactPackage:

https://github.com/lalith26/react-native-fb-login-android/blob/master/android/app/src/main/java/com/fbloginbutton2/MainActivity.java#L29

4. 我包含了facebook登录sdk的gradle依赖项

https://github.com/lalith26/react-native-fb-login-android/blob/master/android/app/build.gradle#L28

5. 我制作了包含Native Component的JS组件:

https://github.com/lalith26/react-native-fb-login-android/blob/master/fblogin.js

6. 最后我使用了JS组件:

https://github.com/lalith26/react-native-fb-login-android/blob/master/index.android.js#L21

我通过网络阅读并发现必须传递propTypes.我也试过了.但应用程序在启动时崩溃了.我无法看到任何日志.所以,我无法找到问题的实际原因.我为一个按钮尝试了相同的一组步骤,它工作正常.

有什么我只是做错了.请帮忙..

我通过logcat访问了模拟器的日志.表明:
