开始使用React Native.我安装了
Android SDK,Java SDK和Android依赖项.在我的终端上运行演示程序时,我收到以下错误.
我的Galaxy Emulator正在运行：
~ emulator @galaxy HAXM is working and emulator runs in fast virt mode emulator: UpdateChecker: skipped version check
现在我运行它：
~ react-native run-android Starting JS server... Building and installing the app on the device (cd android && ./gradlew installDebug)...
