Hi @kamlekar, can you answer a couple of questions so we can help you figure out your problem:

• Are you, by any chance, trying to connect to your device through wi-fi instead of a usb cable?
• Are you on a virtual machine? (possible network problem)
• Are you running geny motion emulator or a regular image coming from the android tooling? (adb.exe sometimes fights with other android sdk installed on your machine)
• Do you have Android Studio installed? Where does your ANDROID_HOME variable point to echo %ANDROID_HOME%? (maybe the path is too long and windows is struggling with it)

[kamlekar]

Hi @Plamen5kov, last time when I checked, it used to work when I used to run cmd as adminstrator. It is my Home PC, and I check it rare.

• Are you, by any chance, trying to connect to your device through wi-fi instead of a usb cable?

I am trying to connect Emulator (which I installed through Android Studio)

• Are you on a virtual machine? (possible network problem)

No, I am on Windows 10 (and I am on high speed network)

• Are you running geny motion emulator or a regular image coming from the android tooling? (adb.exe sometimes fights with other android sdk installed on your machine)

I have no idea, but I am sure I am not running any other emulator.

• Do you have Android Studio installed? Where does your ANDROID_HOME variable point to echo %ANDROID_HOME%? (maybe the path is too long and windows is struggling with it)

It is in {user}/AppData/Local/Android/Sdk. Please check below environmental variables screenshot.

[Plamen5kov]

Can you enter {user}/AppData/Local/Android/Sdk/platform-tools, open a terminal there, run adb devices command and post the result here?

[kamlekar]

Here is the screenshot:

Also, I forgot to tell you that in Android studio, I am unable to find Android menu inside Tools, which was visible before.

[Plamen5kov]

This is often caused by a plugin that's not working could you post a screenshot with File/Settings -> Plugins. You can also try this where people have the same issue as you do.
The missing android option inside tools menu is an indicator of a missing tools folder inside %ANDROID_HOME% directory. Can you please make sure that's the case?

[kamlekar]

@Plamen5kov Here are the screenshots:

[Plamen5kov]

try doing file/invalidate caches and restart and check if tools/android is there

[kamlekar]

@Plamen5kov nope. Still not there.

[kamlekar]

@Plamen5kov I switched the project to the first project which was created when Android studio was installed. And now after sometime, I was able to see Tools => Android :/

I changed the default project once, thinking I can work this nativescript project through Android Studio instead of VS Code.

And then when I checked adb devices as you mentioned above, I was able the see offline devices.

[Plamen5kov]

@kamlekar one thing you can do is restart the adb server by running adb kill-server && adb start-server and try running the emulators and making sure they are online by doing as you have adb devices.

I changed the default project once, thinking I can work this nativescript project through Android Studio instead of VS Code.

In the latest release 3.4.0 of the tns-android platform you actually can open your project in Android Studio. Just open this folder <app_name>/platforms/android with android studio once you have prepared the project, by running tns prepare android.

Hi @Plamen5kov,

I tried as you said. It is still showing as offline:

Hi @kamlekar,
In case the device is showing as offline, you can try following this thread and see if it helps. Unfortunately, because the environment is different on every machine, these kinds of problems can be really difficult to figure out.

I am closing this due to inactivity. Please fell free to write here or open an another issue in case you have some problems.
