Java I/O is Java I/O, by and large.

That's fine, but 90% of what you need to do for that is tied to Java
I/O, not to Android.
Also, your original post suggested that you had not tried anything,
since you did not ask any concrete questions about specific techniques.

You should log your exceptions. I would skip the 2nd parameter on
openFileOutput(). This doesn't seem to have anything to do with byte
arrays and PNG files. You do not need getBaseContext() -- an Activity is
a Context, so you can just call openFileOutput().
Otherwise, it seems fine.
