Hello Maurice,
It does help a lot, thank you very much for your answer!
I'll try to set the permissions back to default.
Still, my app doesn't need all these permissions, and my users were surprised and a bit dubious when they were asked all of these for an offline schedule app which doesn't even use an Internet connection (that I know of). I hope Appery can help me find a way to make it work without it asking for access to the user's camera. 
Cheers - Pascal
Hi Pascal
That was my reason for removing the permissions too. I still need to learn how to remove the ones I don't need without causing this error. I assume you have to remove them in Appery, then export to eclipse and sort the errors out from there before submitting for play store release. I am about to launch my next app and certainly don't want all these permissions! No-one will use the app! So if I find out before you I'll post here for you.
Perhaps Appery Staff will get back to us here and point us in the right direction...
All the best Pascal
Regards
Thanks very much for your help Maurice !
Hello again,
By requesting only minimum permissions (INTERNET, ACCESS_NETWORK_STATE and WRITE_EXTERNAL_STORAGE), my app has stopped crashing.
Thanks Maurice for your insight and Appery support for your quick answer!
