My app does not work on the mobile phone..

My app does not work on the mobile phone without any error appearing on the screen. It just synchronizes for a long time and the app does not open.

What is the solution?

You'll need to provide more details about your app, how you have it configured and what you have tried.

What kind of app is it - what does it do?   More specifically what kind of content and how much of it does it work with.
