Android APK app background different from chrome developer console background
I am working on a cordova android application. The application uses jquery-mobile-1.4.5.min.js and jquery-mobile-1.4.5.min.css . I have problem with the background color of the application. My application when I open the HTML page directly and view it in mobile viewport of chrome/firefox developer console it looks similar to figure in 1
However, When I generate the apk file(using cordova) and install the apk file in my android device I can see an app as shown in figure 2
So, there is a clear conflict between the "chrome developer console" (vs) "application installed version" for the background color.
Can someone give me a reason why this is happening?
