For generic skin emulator with default apis (without google apis):

1. List All System Images Available for Download: sdkmanager --list | Select-String system-images

2. Download Image: sdkmanager --install "system-images;android-29;default;x86"

3. Create Emulator: echo "no" | avdmanager --verbose create avd --force --name "generic_10" --package "system-images;android-29;default;x86" --tag "default" --abi "x86"

   I recommend adding these lines to: ~/.android/avd/generic_10.avd/config.ini
   
   skin.name=1080x1920        # proper screen size for emulator
   hw.lcd.density=480
   hw.keyboard=yes            # enables keys from your laptop to be sent to the emulator

4. Run Emulator: emulator @generic_10 &

Stories not appearing in the browser once the emulator has loaded? Do the following then reload:

adb reverse tcp:7007 tcp:7007

For example:

adb shell
ls /data/user/0/<your-app-id>/files
ls: /data/user/0/<your-app-id>/files: Permission denied

Instead do this:

adb shell "run-as <your-app-id> ls /data/user/0/<your-app-id>/files"

Use adb to automate repetitive text entry like login forms:

adb shell input text YOUR_EMAIL
adb shell input keyevent 61
adb shell input text YOUR_PASSWORD
adb shell input keyevent 66 

adb install myapp.apk

adb logcat Capacitor:V AndroidRuntime:E *:E
