无法在设备上安装该应用程序，请阅读上面的错误了解详情.确保您有一个正在运行的 Android 模拟器或已连接的设备设置你的 Android 开发环境:https://facebook.github.io/react-native/docs/android-setup.html

解决方案

我的 linux 笔记本电脑遇到了同样的问题.我在我的应用程序根文件夹中运行它并工作:

chmod 755 android/gradlew

您必须对 android/gradlew 授予许可.

我在 this github issue

上找到了答案

而且你也必须这样做:

3. 配置 ANDROID_HOME 环境变量
   React Native 工具需要设置一些环境变量才能使用本机代码构建应用程序.
   将以下行添加到您的 $HOME/.bash_profile 配置文件中:
   导出 ANDROID_HOME=$HOME/Android/Sdk
导出路径=$PATH:$ANDROID_HOME/tools
导出路径=$PATH:$ANDROID_HOME/platform-tools

   .bash_profile 特定于 bash.如果您使用其他 shell，则需要编辑相应的特定于 shell 的配置文件.

I m having a problem when I try to run my react-native application in my Android Device. The device is connected even when I make sure that it is.

Device: Huawei Y2 Android Version: 5.1 Debug mode: enbaled the server is running. When i run

react-native run-android

I get this error

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

解决方案

I had the same problem with my linux laptop. I ran this inside my app root folder and worked:

chmod 755 android/gradlew

You have to give permission on the android/gradlew.

I found the answer on this github issue

And you must also do this:

Click here to see the all article on the react-native docs page (the place where i get this information).

3. Configure the ANDROID_HOME environment variable
   The React Native tools require some environment variables to be set up in order to build apps with native code.
   Add the following lines to your $HOME/.bash_profile config file:
   export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

   .bash_profile is specific to bash. If you're using another shell, you will need to edit the appropriate shell-specific config file.
