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 can try an emulated device. Start one from Android Studio or use Genymotion. –  Sep 07 '21 at 11:50
  • @ChrisG How can i start it from Android Studio? – walexy Sep 07 '21 at 12:16
  • Tools -> AVD Manager, then click "Create Virtual Device" in the bottom left corner to create a new virtual machine. –  Sep 07 '21 at 12:24

  • @ChrisG have installed an new virtual device but am still facing this error `[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.` when i run **ionic capacitor run android --open** – walexy Sep 08 '21 at 00:21

    Right, that error message seems pretty straightforward though. Here's a [guide](https://linuxize.com/post/how-to-set-and-list-environment-variables-in-linux/). Check if the environment var exists and set it if necessary. –  Sep 08 '21 at 07:02
  • @Chris G The link helped. I was able to add add it to my evironment variables and am not facing that error again.But am facing another manifest merger failed error in android studio. – walexy Sep 08 '21 at 11:42

I had the same problem, I think it is an error that create a crashe but is not displayed.

This solution worked for me:

ionic capacitor sync

ionic capacitor open android

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.

you have to change your global variable

nano ~/.bashrc

add end the list

export ANDROID_HOME=$HOME~/Android/Sdk/
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:$ANDROID_HOME/emulator
export ANDROID_SDK_ROOT=~/Android/Sdk/

CTRL + O + Enter

source ~/.bashrc

restart you computer

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.
