React Native FB-SDK找不到符号callbackmanager

Question

react andation and fbsdk版本：

"react": "16.6.3",
"react-native": "0.58.5",
"react-native-fbsdk": "^0.8.0"

我有以下错误：

> Task :app:compileDebugJavaWithJavac FAILED
C:UsersxxxxDesktopprojectandroidappsrcmainjavacomprojectMainApplication.java:22: error: cannot find symbol
  private static CallBackManager mCallbackManager = CallbackManager.Factory.create();
                 ^
  symbol:   class CallBackManager
  location: class MainApplication
C:UsersxxxxDesktopprojectandroidappsrcmainjavacomprojectMainApplication.java:24: error: cannot find symbol
  protected static CallBackManager getCallbackManager() {
                   ^
  symbol:   class CallBackManager
  location: class MainApplication
2 errors
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

这个问题似乎与代码的这一部分有关，但我无法弄清楚什么问题。我完全遵循其正式存储库中提供的说明。

public class MainApplication extends Application implements ReactApplication {
  private static CallBackManager mCallbackManager = CallbackManager.Factory.create();
  protected static CallBackManager getCallbackManager() {
    return mCallbackManager;
  }
  // ...
  @Override
  protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      new FBSDKPackage(mCallbackManager)
    );
  }
  // ...
}

我还手动将以下导入添加到MainActivity.java：

import com.facebook.CallbackManager;
import com.facebook.FacebookSdk;
import com.facebook.reactnative.androidsdk.FBSDKPackage;

将这些行添加到app/build.gradle：

implementation project(':react-native-fbsdk')
implementation 'com.facebook.android:facebook-android-sdk:4.34.0'

，这些是 settings.gradle：

include ':react-native-fbsdk'
project(':react-native-fbsdk').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fbsdk/android')

如果某人碰巧遇到了同样的问题，这与NPM无链接FB-SDK有关。我尝试使用npm install和npm link，但尽管没有任何错误，但没有成功。但是，使用react-native安装SDK解决了问题：

react-native install react-native-fbsdk
react-native link react-native-fbsdk

试图链接时是否遇到Module_NOT_FOUND错误，请在项目root文件夹上打开命令行并运行：

cd android
gradlew clean

此外，尽管他们的官方GitHub存储库确实包含有关安装过程的说明，但我建议使用Facebook开发人员页面，因为它在可读性和详细信息方面要好得多。
