我尝试重新安装android studio并按照两个新项目执行两次安装步骤。

我的App.js是默认的App.js.我也尝试过使用facebook登录的App.js示例。

您可以通过在MainActivity.java中添加导入来修复它：

import android.content.Intent;

此外，当您的sdk版本与react-native-fbsdk版本不同时，此错误主要发生。例如：假设你的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'
    }
}

但是你的react-native-fbsdk却有所不同

因此，您需要检查是否使用相同的sdk版本。

转到node_modules / react-native-fbsdk / android / build.gradle并将版本与项目build.gradle进行比较。
