Build a Photo Album - blank screen at end of step 1

[Mainroad]

I ran through the interactive tutorial for "Build a Photo Album" a month or two ago successfully.

Today I deleted the project it created and tried to step through the same tutorial again.

When I try to "Run -> iPhone" at the end of step 1, the simulator iPhone screen is blank (white).

If I use AppBuilder to run the project on an actual iPhone or Android the result is the same.

What's going on?

I'm on Windows 8.1 and using a Chrome browser.

I've tried using F12 in the simulator to see if I can find an error, but no luck.

Any help would be appreciated!

It was a syntax error in the html.  Unfortunately no errors arise from it.  It just stops the app from working.  Ouch!

I run into the same situation. All blank windows situations was rised from bugs. It's easy to catch, but you need to start project on "Custom device" (ctrl+F12) instead on iPhone simulator. After that you can invoke console with F12 and locate your bug. 

 

 In most cases it was an open braket or something simple :)

Hi all,

@Zdravko
Thanks for your input, indeed, this is correct. Usually a small JavaScript error can break the UI. You can observe these errors in the Developer Console of your browser that runs the simulator after hitting F12.

Note that this is available with any of the devices in the simulator, not only with a Custom Device option.

In case you need to verify your code against the completed tutorials - here is the list.

Let me know if further questions arise.
