Question

我一直试图推出AwesomeProject应用程序两天，但没有成功。

我一步一步地按照入门教程（适用于Windows / Android的v0.42）进行操作。

这就是我所做的：

安装Choco / Node / React-native
进入工作区文件夹并致电

react-native init AwesomeProject

成功。

启动新的Android模拟器（＆gt; adb设备看到它）然后运行

cd ./AwesomeProject
react-native run-android

我得到以下内容：为react-packager启动一个新的命令提示符窗口，然后启动然后永远等待：

如果我在模拟器中点击重新加载（R，R），我现在有错误屏幕＆＃34;无法连接到开发服务器。＆＃34;

Could not connect to development server...

此时不知道该怎么做。

这https://stackoverflow.com/a/38874952/3249701绝对没有。

这也不是https://stackoverflow.com/a/40500277/3249701

我在哪里可以获得正确的堆栈跟踪或相关的日志消息，以了解我哪里出错了？

谢谢，

现在，React Packager还没有完全启动。关注消息后，它会冻结：

我尝试在开发设置中设置我的IP（来自＆gt; ipconfig），但没有成功。我回到了10.0.1.1:8081，但现在包管理器根本无法获得应用程序。我尝试的越多，它就越混乱。

在模拟器上我试图摇动它，进入开发设置，将主机设置为空，而不是重新加载。我收到了以下错误：

                                                                 • Ensure that the packager server is running

                                                                 • Ensure Airplane Mode is disabled
                                                                 • If you're on a physical device connected to the same machine, run 'adb reverse tcp:8081 tcp:8081' to forward requests from your device
                                                                 • If your device is on the same Wi-Fi network, set 'Debug server host & port for device' in 'Dev settings' to your machine's IP address and the port of the local dev server - e.g. 10.0.1.1:8081

Answer 1

我有同样的问题。我还没有找到完整的解决方案，但我可以通过遵循Akhi的指令间接启动设备中的应用程序。

在./android/app/src/main/文件夹中创建空白资源文件夹。
react-native bundle --entry-file index.android.js --platform android --dev false --bundle-output ./android/app/src/main/assets/index.android.bundle --assets-dest ./android/app/src/main/res/. 此步骤未显示任何错误。
打开Android Studio，打开关于android文件夹的项目。
在终端窗口中运行：gradlew。
Android Studio＆＃39;运行命令以在虚拟设备/移动电话中启动应用程序。

我仍在等待React-native的完整解决方案。

Answer 2

如果出现错误，请在终端上的项目根文件夹目录中运行npm test，然后它会显示问题。如果没有问题，请运行命令npm start并在任何Android设备上从android studio运行您的项目。启动后，将机器的IP地址设置为开发设置，然后设置端口8081，然后重新加载。

Answer 3

答案是打开两个终端

终端1：转到react-native项目并运行命令react-native start

终端2：转到react-native项目并运行命令react-native run-android

这个错误不会来。尝试这个解决方案。它会工作。在本机文档中缺少这个东西。
