Problem while saving file on Android Lolipop from second generation moto-g

Question

Good morning, I have an app that works normally on all versions of Android from-the 2 to the first generation moto-g version, this app is very simple, I describe the details I need to add in the photo name, I take the photo and it saves the photo with the information I described, today when trying to use it in a motorcycle-g second generation the application does the whole process as if everything is happening correctly but when I go in my files the folder is not there, I did a debugging and realized that it fails to create the folder "DBQ_LTQ" folder where saved the photos, it creates and deletes at the same instant tried to create manual and gave the same problem, I tried then to change the directory and save on the main page of the internal memory with another name and the error persists, uninstalled the application and the folder appeared without any file, follow the code below:
