I have an android app which is recording audio and outputting it withe the name audiorecorder to the local storage on the phone. Now i would like store a .txt file as well in same directory.
I have tried several methods from stack overflow, the app doesn't complain but does not store the .txt as it should. I can't figure out why.
The methods of interest is: CreateTxt and generateNote. These are the ones that doesn't do what they are supposed to.
These methods are used within the startR.setOnClickListener method.
Can anybody see why? Thank you in advance.
