Android append text file

Question

I am tring to record the wake time and sleep time from a dialog picker to a text file like this, but the call to the method commitToFile2 doesn\'t append the text file \"sa

Answer 1

In your commitToFile2() method, after fw.append(entryString); try adding fw.flush();

FileWriter is a subclass of OutputStreamWriter and the write() methods of that class will not necessarily 'flush' data automatically.

Answer 2

that's so you retain your MODE_WORLD_READABLE

openFileOutput("savedData.txt", MODE_APPEND | MODE_WORLD_READABLE ); 

Answer 3

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.
