Total time: 5.993 secs 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/getting-started.html
Run this command to clean project:
cd android && gradlew clean
After, run the following command to run project again:
cd .. && react-native run-android

I had same issue and solved by this,
1) Install watchman from here.
but installing watchman requires other dependencies and throws errors, install them one by one without missing any.
2) Go to your project folder from where you run commands as react-native run-android,
3) run following commands or puth this commands in one file and save with extension .sh e.g. filename.sh.
touch .watchmanconfig
watchman watch-del-all
watchman shutdown-server
sudo pkill -9 -x fseventsd
echo fs.inotify.max_user_instances=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
echo fs.inotify.max_queued_events=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
even if this doesn't help, then install expo client in real-android phone, and run.
