Hi everyone,
I have a problem with the initialization of mapfragment, I state that I am not using the designer file and I configure the objects manually, using mapfragment as you can see from the code I always get an error, I can not understand how I can do to delete it. If anyone can kindly give me some indication. Thank you.
This is the error Log :
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
