Running on the Emulator

Running the App on the Android Emulator

npx cap run android does all of this in one step (cap run), but it can restart the adb server, so on a machine shared with other emulators build and install by hand:

Build, sync, install and launchShell

npm run build && npx cap sync android
(cd android && JAVA_HOME=/usr/lib/jvm/java-21-openjdk-amd64 ./gradlew assembleDebug)
adb -s emulator-5558 install -r android/app/build/outputs/apk/debug/app-debug.apk
adb -s emulator-5558 shell am start -n com.example.booknest/.MainActivity
adb -s emulator-5558 logcat -v tag -s Capacitor -e "Loading app|App started" -m 2
