"Installation of the application failed. Run time error has eccured. Fix the capabilities in WMAppManifest.xml file."

Question

I was building this simple application for WP8. Everything was working fine until today I had to add a new capability to the manifest file to allow access to sensors. I just used graphical editor to tick ID_CAP_SENSORS. Now every time I try to deploy my app I get:

Installation of the application failed. Run time error has eccured. Fix the capabilities in WMAppManifest.xml file.

Here is my whole manifest file:

<?xml version="1.0" encoding="utf-8"?>
<Deployment xmlns="http://schemas.microsoft.com/windowsphone/2012/deployment" AppPlatformVersion="8.0">
  <DefaultLanguage xmlns="" code="en-US" />

    </ScreenResolutions>
    <Requirements>
      <Requirement Name="ID_REQ_GYROSCOPE" />
    </Requirements>
  </App>
</Deployment>

My manifest file seems ok to me. I have no idea how to debug that. Compiler is not even showing were exactly I have the problem. I will be very glad for any hint.

Answer 1

The HTC 8S doesn't have a gyroscope (I've just tried one). That is the error you get if you specify:

<Requirements>
  <Requirement Name="ID_REQ_GYROSCOPE" />
</Requirements> 

and try running the app on a dev phone without a gyroscope.

Of course the App Store would hide any such apps so the HTC 8S wouldn't be able to download them.

Answer 2

Wow! After having wasted some time trying to solve this problem I eventually solved it by just keeping only those capabilities which I am actually using, no less, no more! In my case I only needed internet permission so here is how the capabilities part of my WMAppManifest.xml looks now

<Capabilities>
      <Capability Name="ID_CAP_NETWORKING" />
</Capabilities>
