loading saved score [closed]

Answer 1

Writing a file for passing just a few bytes is probably a bit too much.

You could simply use SharedPreferences instead. (see here).

Or in case you only want to pass the score to the next activity, you could just use:

/* pass extra data to next activity */
intent.putExtra("score", yourScore);

/* get passed data */
getIntent().getIntExtra("score", -1); // -1 will be returned if no score was passed
