How can i run ionic-capacitor app on Android-studio or mobile device?

Question

I am trying to run an ionic-capacitor app on android studio or my android phone.

When i run

ionic capacitor run android

It shows:

? Which device would you like to target? (Use arrow keys) and it not showing me any option. i pressed the arrow key still nothing and when i pressed enter it shows:

TypeError: Cannot read property 'value' of undefined

Then i tried

ionic capacitor run android --open After compiling it shows:

[capacitor] [error] Unable to launch Android Studio. Is it installed?

[capacitor] Attempted to open Android Studio at: /usr/local/android-studio/bin/studio.sh

[capacitor] You can configure this with the CAPACITOR_ANDROID_STUDIO_PATH environment variable.

I searched online on how to set CAPACITOR_ANDROID_STUDIO_PATH but i didnt see any solution.

Finally i also tried following the steps in this link in a Stackoverflow answer.

I run adb device to show my device ID

Then i tried

ionic capacitor run android --target 0441925667003082

It showed the following error:

[ERROR] 0441925667003082 is not a valid Target ID.

Use the --list option to list all targets.

I tried to use the --list to list all target but it showing [INFO] No native targets found. despite my android device being connected and showing in the adb devices.

What am i doing wrong in all this steps ?.

How can i run ionic-capacitor on android studio and on my mobile device ?.

You need to make sure your environmenent variable ANDROID_SDK_ROOT points to the android sdk location.

Also try re-installing @capacitor/cli and native-run

1. Usually capacitor sometimes not detect device even-though the device is connected. This is due to authentication issue .
2. To solve this, in Developer options tap on revoke authentications/permissions (verify with your phone).
3. Turn off USB debugging , turn on USB debugging and Try again.

Answer 7

I had this problem recently. The problem is that I installed AndroidStudio in a random folder.

When you use ionic capacitor run android --open it appears in the /usr/local/ directory. To solve the problem, just move the AndroidStudio installation to this location.
