在Android模拟器上运行react-native [英] Run react-native on android emulator

问题描述

我尝试在Mac上的genymotion android模拟器上运行react-native应用程序。
当我写 react-native run-android 时

I try to run react-native app on genymotion android emulator on my mac. When I write react-native run-android It gets

Running /usr/local/opt/android-sdk/platform-tools/adb reverse tcp:8081 tcp:8081
error: closed
Could not run adb reverse: Command failed: /usr/local/opt/android-sdk/platform-tools/adb reverse tcp:8081 tcp:8081

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html
MacBook-Pro-MacBook:ART-CarefulPeople macbook$ 

然后我试过：

1. react-native开始


2. react-native run-android

1. react-native start
2. react-native run-android

相同的结果。

然后我尝试了：

1. react-native包--entry-file index.android.js --platform android --bundle-output android / app / src / main / assets / index.android.bundle

curl http：// localhost： 8081 / index.android.bundle？platform = android -o android / app / src / main / assets / index.android.bundle

react-native run-android

相同的结果。

我只尝试了 adb反向tcp：8081 tcp：8081 ，它说错误：已关闭

当我尝试在android-sdk模拟器上运行应用程序时，上面得到了相同的错误，但没有错误：已关闭。

When I try to run app on android-sdk emulator it gets the same error above but without error: closed.

在android studio中，我可以运行此应用，并且它可以在genymotion上运行。
请告诉我如何在android模拟器上运行我的应用程序？

From android studio I can run this app and it works on genymotion. Tell me please what should I do to run my app on android emulator?

推荐答案

我遇到了类似的问题，并且在花费了很多时间并进行了很多搜索之后，唯一的技巧对我有用：

I had a similar problem, and after spending so much time and lots of searching about this issue the only trick worked for me:

1. 请按如下所示安装所需的SDK此图

配置所需的SDK

1. 如果已经安装了它，则必须更新以下SDK： b
   $ b
   
   
   • Android SDK工具（将其更新为最新版本）
   
   
   • Android SDK平台工具（将其更新为最新版本）
   
   
   • Android SDK生成工具（将其更新到最新版本）
   
   
   • Android支持存储库在 Extra


1. If You have already installed it, so you must have to update the following SDKs:
   • Android SDK Tool (update it to latest version)
   • Android SDK Platform-tools (update it to latest version)
   • Android SDK Build-tools (update it to latest version)
   • Android Support Repository under Extra folder (update it to latest version)

注意：支持库的本地Maven存储库，在React的官方文档中列为SDK要求-native现在在SDK Manager中被命名为Android Support Repository。

Note: Local Maven repository for Support Libraries which is listed as the SDK requirement in the official docs of React-native is now named as Android Support Repository in the SDK Manager .
