您需要正确设置ReactNative。

我认为已经安装了android studio，并且已经连接了模拟器或android设备

执行以下步骤！

1] 从official site

安装JDK

2] 从official site

安装NodeJ

3] 安装Python 2表单official site

4] 安装ReactNative CLI，打开CMD [右键单击并以管理员身份运行]

键入C:\WINDOWS\system32>node -v //以获取节点版本
键入C:\WINDOWS\system32>npm install -g react-native-cli //以安装RN CLI

5] 创建RN项目的工作区 -D:\ReactNative>react-native init projectname //它将在提到的路径内生成项目。

6] 设置环境变量

在用户变量（如果不存在）JAVA_HOME下设置新变量，其值为 C:\Program Files\Java\jdk-10.0.2（您的JDK路径）
在用户变量（如果不存在）Path下设置新变量，其值为 C:\Users\Admin\AppData\Local\Android\sdk\platform-tools //您的SDK平台工具路径

7] 使用CMD中的以下命令运行项目 D:\ReactNative>react-native run android

如何在Android中调试“构建失败，出现异常/找不到SDK位置”？
