问题
I'm trying to write a file in my app's android internal storage space. After so many trials, I was finally successful using this method Writing/Reading Files to/from Android phone's internal memory . However, when I go to data/data/package_name/files, I cannot find my package, and cannot even find the MyFile.txt. In fact, I can't find them anywhere in internal memory. Why is that?
