The reference to button_id is probably a mistake. Button mButton = (Button) findViewById(R.id.button); final Button button = … Read more

Your problem stems from poorly thought out and/or formatted path strings. Instead of concatenating raw strings, use os.path.join(). And make sure you’re always passing absolute paths. In that same vein, using string methods directly instead of “+” is often more efficient and usually more readable. With those in mind, working code: import os def rec(direc, … Read more

I think what you are confused about is the modulo operation. At least the text does not fit to what it is doing.
