React Native 运行保持在 IDLE 状态

Question

这是我第一次在Ubuntu 18.04 LTS. 我已经完成设置，并尝试使用react-native run-android命令在设备上运行应用程序。这是我在终端中得到的输出，

ron@lenovo:~/react/app$ react-native run-android
Scanning folders for symlinks in /home/ron/react/app/node_modules (9ms)
JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug)...

NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to /home/ron/Android/Sdk/ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

File /home/ron/.android/repositories.cfg could not be loaded.
Checking the license for package Android SDK Build-Tools 26.0.3 in /home/ron/Android/Sdk/licenses

它永远保持在空闲位置。这个问题有什么解决方法？
