I figured it out….I had to change the line
FileOutputStream fOut = openFileOutput("savedData.txt", MODE_WORLD_READABLE);
to
FileOutputStream fOut = openFileOutput("savedData.txt", MODE_APPEND);
After that I was able to append the text file without overwriting the data that was already inside the text file. Thanks for your assistance guys. I guess going to the 4th page on google IS useful sometimes.
