我已经尝试重新安装 android studio 并在两个新项目中按照安装步骤执行两次。

我的 App.js 是默认的 App.js。我也尝试过将示例 App.js 与 Facebook 登录一起使用。

您可以通过在 MainActivity.java 中添加导入来修复它:

import android.content.Intent;

此外，此错误主要发生在您的 sdk 版本与 react-native-fbsdk 版本不同时。例如:比方说，build.gradle 中的 SDK 版本是:

buildscript {
    ext {
        buildToolsVersion = "27.0.3"
        minSdkVersion = 19
        compileSdkVersion = 27
        targetSdkVersion = 27
        supportLibVersion = "27.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

但是在你的react-native-fbsdk中是不一样的

所以需要检查是否使用了相同的sdk版本。

Go to node_modules/react-native-fbsdk/android/build.gradle and comare the version with your project build.gradle.
