[BUG] Can't debug a .net 8 for android app on a fireTV when running from vscode on mac.

[TOberlie]

Describe the Issue

We have a fireTV app which is written in .net 8 for android. I recently had to switch from using Visual Studio 2022 on pc to vscode on a mac. I am unable to run and debug the app from vscode. This issue only happens with .net 8 and only on a firetv stick. If i try running a .net 8 for android app on a mobile android device, it works fine whether i use usb debugging or wireless debugging. If I try running a test app written in kotlin from android studio, I can run and debug it on the firetv device. The only way I am able to run the .net 8 app on the firetv device is by attempting to run it from vscode, deleting the app that gets installed from the firetv, then using adb to manually install the signed apk on the firetv. I’ve also tried using an android tv emulator, but it almost always freezes up and when it doesn’t freeze it fails to fetch data from our api so i am unable to reliably test the app. One thing I’ve noticed is a message in the build output instructing me to start sdb and connect my device, but from what I understand sdb is meant for tizen apps.

Steps To Reproduce

Create a .net for android application and attempt to run and debug it from vscode.

Expected Behavior

The app should launch and you should be able to set breakpoints

Hi @TOberlie,

We need to make sure we understand your use case before being able to help.

Do you see the FireTV stick in the list of launch targets before attempting to launch and debug the app? Before doing F5, you are supposed to select your startup project and launch target, by clicking on the "{}" (language status item) at the bottom right of VS Code (while having a .cs file opened).

As far as I understand, that's your real issue. If not, what happens that prevents you to run and debug your app? Are you getting a build error, a deploy error, a debug error?

If you can be more specific on what is exactly failing for you, it would be helpful.

Also, sharing the build output from the VS Code terminal might help as well.

Thanks

Hi @mauro ***@***.***>, Yes, I can see the fire tv device in the debug targets. I have that selected as well as my startup project. When attempting to run and debug the app, the build succeeds. I do not get any errors. The debug session starts and usually ends within a second. Occasionally I can see the firetv attempt to launch the app before it goes back to the home page. Very rarely, it will launch the app and will get stuck on our main launcher activity, but it will only show the background of that activity. None of the other views are displayed. However, it works fine if I manually install the apk via adb. I am attaching the build output, debug console output and a screenshot of the language status item.

Hello @mauro ***@***.***>, I tried to run the app from vscode this morning. The app launched and the debug session remained active. The background of our authentication activity was shown, and it took a few minutes for the rest of the views to be displayed. After clicking a skip button on the auth page, it took around 15 minutes for the player to load and start playback. I am attaching the build logs and debug logs to this email.
