Answer 1

Check these lines:

String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/MyDraw");    
myDir.mkdirs();
file = new File (myDir, name+".png");

file is the File object that points to the location where the Bitmap is saved.

Answer 2

When onActivityResult() gets called back in your application, the intent contains the uri of where the file was stored. Pull it out of there and save it

Answer 3

First of all, you need the name that the user entered to save the filename with. You can save the filename the user inputted by saving to a pref (or they just entered it, then you should still have it). Once you have the filename, you can simply get the file by:

String fileName = //get the file name
File f = new File(Environment.getExternalStorageDirectory(), "/MyDraw");
f = new File(f, fileName);

---

If you don't know the filename, you can loop through the file directory:

File dir = new File(Environment.getExternalStorageDirector(), "/MyDraw");
for (File f : dir.listFiles()) {
    //Do something with this file
}
