[kadia8161]

I have Created a project in phoneGap and running it on Oracle Virtual box Android Emulator(downloaded using genymotion).
I need to know how can i debug project using vs-cdoe
I have added extension for cordvoa tools in vs code

@kadia8161 if you run adb devices, do you see the emulator show up? If not, can you follow the instructions at https://www.genymotion.com/faq/#adb-other-workstation-connection to connect adb to the emulator?

Once adb can connect to the emulator, from there you should be able to treat it as a device in vscode. You can verify this by trying to run cordova run android and see if the app installs and runs on the emulator. You do not run cordova emulate android since that will attempt to launch the google android emulator rather than using the genymotion emulator.

sorry for late replay
thanks to @MSLaguana for guidance.
i go through that link provided by you i am still facing problem connecting VirtualBox device using adb connect but that is not concern with this so first i will solve it and then try to connect device from vscode.

@mbraude i will let you know if i have any other issue.

Note : I am able to run same app using phoneGap windows application on virtual device

can you help me out...

[MSLaguana]

For your first issue there, that ERR_EMPTY_RESPONSE is happening inside your app. Do you make XMLHttpRequests? when simulating in a browser (which does not require an emulator at all, by the way) we proxy XHR to get around CORS issues, but it may create other issues on corporate networks it seems. You can try specifying "corsproxy": false, in the launch.json entry.

For the second issue, what happens if you try to run cordova run android --device in your project?

[kadia8161]

@MSLaguana
it is a very basic HelloWorld kind project
in my config file have some cordova plugins included
which i commented i have attached config if you it can help you.

( i can see chrome trying to load page)

i have installed gradle and other required files
i am not sure what problem is because i can run same project from phoneGap windows client in virtual android device using phoneGap Developer App

i have one more doubt regarding cordova
while building app from command prompt using
cordova build android command it downloaded many files related gradle and others i think it downloaded to temp location so if i clear temp files do i need to download again all files or can i choose download location for reuse ?

config.txt

[MSLaguana]

Regarding your issue with building android, according to http://stackoverflow.com/questions/30692085/cannot-build-project-using-cordova it may be due to a corrupt gradle download.

For your first issue, I believe it may possibly be caused by having the inappbrowser plugin installed twice. You have both cordova-plugin-inappbrowser and org.apache.cordova.inappbrowser referenced in your config.xml, and there is an issue in the version of cordova-simulate we use that I think you are hitting.

Your project should only use one version of the plugin, so I suggest removing the outdated org.apache.cordova.inappbrowser instance, make sure it is uninstalled from the project, and then see if that works for you.

@MSLaguana
as per your suggestion i have looked and i found there were actually two reference for crodova one was from gap (added by phonegap) and other was added when i tried to build using Cordova build android.
i took a fresh project using cordova add and it is able to run on browser using "simulate Android on browser"

But i have one more doubt when i use cordvoa build android or try to Run android on device it give me error (probably because of corrupted gradle files)
but same project runs perfectly on Simulate Android on browser.
any reason for that ? does it not use any gradle reference during browser run ?

and yes i have downloaded separately gradle all zip file from its site how can i use it with vscode so vs code will reference it instead of previous one ?

[MSLaguana]

When you simulate your project in the browser, it does not use any of the native implementation, just the html, css, and javascript in your project. We provide a fake "native" implementation of plugins so you can test things out, but we don't actually build the native project.

Did you try the suggested fix in the stack overflow question? Deleting / replacing the gradle zip in your user directory?

[kadia8161]

in my project it uses gradle-2.13 while i have downloaded higher version of gradle Version 3.0 (while downloading i thought it would be better to use latest version) so right now i am looking for way to change version of gradle it use during build and how can i set to use gradle from different path (set manually) rather than using from C:\Users

If you have any idea or you can provide some reference link regarding this it will helpful.

I think there should be option to set path ,version and other details for other libraries we used during cordova build so we can specify manually also.

I will update as soon as i sort out this gradle error.

[MSLaguana]

I haven't done this myself, but it looks like http://stackoverflow.com/questions/30413485/install-gradle-for-using-in-cordova-build-android has instructions for using a specific version of gradle.

We don't explicitly reference/require gradle anywhere in our extension, so I'm inclined to leave things with cordova configuration like the above. If you strongly disagree, we can discuss possible changes.

This looks pretty old. @kadia8161, I'm going to close this but feel free to reopen if you're still experiencing any problems w/ debugging
