Aren't the methods in the Context class specific to the files within the application private file store? I've been trying to find a way to export data out of the applications space to the sdcard, the solution above by ggcespia is the only I've found that works. The methods I tried in the Context class where openFileOutput which again, saved the file within the directory data/data/com.myapp/?files?, not exactly sure about the last directory path, but regardless, it was not to the sdcard. Is there another method in the Context class that I'm missing that will specifically access the SD Card?
