Question

我正在开始使用本机反应。安装Android Studio后，和JDK，我尝试使用react-native run-android

来编译android项目

但我收到此错误：

JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug)...

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/riccardoconti/Documents/ReactNative/rncourse/android/app/build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':app'.

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:

我已经尝试过但没有成功的东西：

更新到最新的JDK（Java 1.8.0_20）
在Android Studio上，转到“项目结构”->“ SDK位置”->选择“使用嵌入式JDK（推荐）”
创建相对资产文件夹后，我使用了react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

有任何线索吗？

谢谢。
