Blank White Screen after installing the Application

[Anup]

Hello Team,

I am developing an hybrid mobile application using telerik appbuilder visual studio extension and kendo mobile, whenever I build application and download the apk and try to install the application I get a white blank screen after the splashscreen exits and white blank screen remains.

I tried adding delay to splashscreen hide function, but didn't work for me. 

Please let me know how do I avoid this white blank screen which happens while installing the application for the first time. Please help me with some examples or best way of handling it.

 

 

Thanks:

Anup

Hello Anup,

Do you get the same white screen in the Device Simulator? If so, then most probably JavaScript exception was raised. Would you please open the developer console by pressing the F12 key (or through the Debugger button on the Simulator) and check for any errors listed under the Console tab.

It is not clear, do you get the Splashscreen displayed initially or not? A reason for not showing the screen would be because the Splashscreen plugin is disabled. You can check this as explained in the Enable and Disable the Core Plugins topic.

In addition, you can try debugging on a Device with the Debug on Device tools (iOS, Android - look for AppBuilder debug tools).

Do you also observe the same behavior on a new project created from template? If so, would you please share which is this sample app so that I can verify the same on it?

Hello Vicente,

Based on the provided logs, it looks like you are developing an application with Xamarin. In this forum, our support engineers can provide assistance only with hybrid Apache Cordova application. You would receive better answers if you post this question in a Xamarin related forum.

Having said that, please let me know if I misunderstood your case and you are in fact developing a hybrid Cordova application.
