我正在尝试使用Linux Mint在Android虚拟设备上运行初始应用程序。我已经尝试了很多次，但没有任何改变，感觉它由于某种原因被卡住了！这是来自Code studio的终端：
~/Music/app/app$ react-native run-android
info Starting JS server...
info Building and installing the app on the device (cd android && ./gradlew app:installDebug)...
Starting a Gradle Daemon (subsequent builds will be faster)
