Qt app cannot be loaded on android device

I'm currently developing an android app. After successful compilation it starts with white screen, app icon and app name without loading the actual qml file. I can provide some code if it needs. But putting all in here is kind of an overkill i guess since its multiple thousand lines. If i start the app on my device i get the following output.

W ResourceType: No package identifier when getting name for resource number 0x00000000

I think problem in this lines
