no devices/emulators found when trying to use ionic cordova run android --device

The Connected Device:

When I run: ionic cordova run android --device I get this output:

BUILD SUCCESSFUL in 5s
42 actionable tasks: 42 up-to-date
Built the following apk(s):
    C:\Users\K-PC\myApp\platforms\android\app\build\outputs\apk\debug\app-debug.apk
native-run.cmd android --app platforms\android\app\build\outputs\apk\debug\app-debug.apk --device

        Re-running this command with the --verbose flag may provide more information.

I checked to see if the device was listed using native-run android --list and I get this output:

Errors (!):

  ERR_UNSUITABLE_API_INSTALLATION: No suitable API installation found.

Connected Devices:

  No connected devices found

Virtual Devices:

  No virtual devices found

I have Android Studio installed, I have two virtual devices in my AVD manager:

AVD Manager

I want to deploy the APK onto the device connected to my laptop, not these emulators but its strange to see that it hasn't even recognised the emulators inside my AVD manager

How can I fix this issue? I hope I have given enough detail.

Solution

  • Using ADB

    adb devices

    That command should give you a list of the attached devices. You must accept the debug mode on the phone. Before trying to run the app with a hardware device you should check that adb has a connection with one device atleast.Some issues may appear like:

    1. List of devices are empty: That means that the device is either not properly connected or there's an issue with the USB cable(may be broken).
    2. Unauthorized: Appears when you didn't accept the debug authorization of your phone.
    3. Offline: The phone has a little service called daemon that allows it to connect with the computer so can transfer the files and listen to changes. When this service is not running it stops the connection with the computer. Can be solved by rebooting the device or connect/disconnect the USB cable until it can be shown as "online".

    In summary you should run this code:

    1. Enable Debug mode on your Android device. Also enable USB debug that is in the same configuration view.
    2. Run adb devices, Authorize to connect with the computer. Solve the issues(if there's any) already commented above.
    3. Run ionic cordova run android --device.
    4. Happy coding time!.
