Ionic cordova run/build/emulate android not working

Question

When I do adb devices -l I could see my Oneplus in the list.

Doing ionic cordova run android doesn’t open my app on my phone. I also tried doing ionic cordova --device=<device_address> but that didn’t work also.

I also noticed that doing ionic cordova build android didn’t make an apk that I could copy and past over to my device so that I could manually install it.

Tried ionic cordova emulate android that also didn’t work,

Here's a result when running ionic cordova run android --device

[OK] Your app has been deployed.
     Did you know you can live-reload changes from your app with --livereload?

[11:49:23]  lint finished in 14.23 s

I also tried adding the --livereload flag and entered the External URL on my Chrome App. I was getting these messages when visiting the url:

Result on Terminal:

Any idea on how to get this running?

Might I politely also suggest your question title can be tweaked to not say "build/emulate" as you are really talking about just "run" in this case. — Greg Netland

This may not solve your exact problem, but this worked for me.
I was having the exact same issue and I changed android phones from a Pixel XL running 8.1 to a Samsung S7 running android 7 and it worked.

To solve my Pixel 8.1 problem:

cordova platform list (verify which version you have)
cordova platform rm android (if you dont have 7.1.0)
cordova platform add [email protected]

I then had to make sure my minSDKversion was 19 in my config.xml

This might also help - ionic add platform android with custom android-target
