I'm working on a Cordova project for Android using Visual Studio 2015. I can build my project without error and I can deploy it on Ripple.
But when I want to deploy on a real device or on an emulator, I'have always the same error: the specified file was not found. No more information in error list or output (using diagnostic output).
When I try to deploy on the emulator, the emulator receive the application and I can use it but when the app is lauched I have a pop-up from Visual Studio: "the specified file was not found" and I can't debug.
When I try to deploy on a real device, I have directy a pop-up: "there were deployment error. Continue ?" if I click on "yes", I have the popup "the specified file was not found".
I would like to have a solution and an explanation about this error.
Thank you in advance, I can't work with this kind of error except deploying on emulator and don't use debugging...
It seems like you are missing a third party component (such as Android Studio), so Cordova is creating an Android project, but Android is not compiling that project into an Android app. That's why it deploys on Ripple (which just uses the first half of the build) but fails on the second half. I'd make sure that you do have Android home set up (check the path in Tools->Options->Tools for Apache Cordova). Otherwise, feel free to email your question + current project to vscordovatools#microsoft.com. I can take a look at it on my machine.

I have just started internship in a company, they said i will be working on a android project using qt.I need to join them by next week, in meantime i thought of installing qt on my laptop which has Ubuntu 15.04(64-bit).
I downloaded Android SDK, Android NDK, Ant Executeable.
Here is my android settings in qt.
I created a sample app using New Project -> Qt quick Application,it pasted some sample code for hello world when i tried running it it said
could not find the executable please specify one qt
then i opened my project folder and specified a file having name same as my project name,fortunately it worked.
Now when i run the project it displays hello world but when i try to debug it either by attaching external device or through emulator it displays a pop-up which displays a string "Unknown error".
1.Have i specified the settings correctly?
2.how to get rid of this error and start debugging.
