Re: Can't launch app on device

Hi @Tom74

 

In the device, click on alt + 'l' + 'g' + 'l' + 'g'.

 

This should open the device log and give you some more info on the problem.

Re: Can't launch app on device

It would be easier to assist if you added a code snippet of the initilization of your app. Maybe there is something that you're missing.

 

Also, why would you compile for 4.6 to run on an OS 6 device ...

Re: Can't launch app on device

Before adding this code, can you confirm that this code works fine on a Simulator, preferrably a Simulator for the same device you are trying it on?

 

Then try debugging on device - that way you get to see the log and you get to stop your application.  The process of debugging on device is described here:

If this doesn't help you, then please post your 'main' method.
