How to save a file that is accessible to the user outside of the app and also deletes on app uninstall?

Requirements of app:

I came across this post (How can I let users access the internal storage directory of my app?) where the OP seemed to be wanting the same behavior I do and seemed to have it solved by using getExternalFilesDir() [last post] but when I use that method my files are not visible to the user outside of my app. So how do I get both functionalities in my app? 

externalDir = mContext.getExternalFilesDir(null);
File myDir = new File(externalDir.toString() + "/my_snapshots");
myDir.mkdirs()
String fname = "Image-" + n + ".jpg";
            File file = new File(myDir, fname);
FileOutputStream out = new FileOutputStream(file);

MediaScannerConnection.scanFile(mContext, new String[] { file.toString() }, null,
            new MediaScannerConnection.OnScanCompletedListener() {
                public void onScanCompleted(String path, Uri uri) {
                    Log.i("ExternalStorage", "Scanned " + path + ":");
                    Log.i("ExternalStorage", "-> uri=" + uri);
                }
            });

That is the correct solution.

That is because you did not index the files using MediaScannerConnection and its scanFile() method. Once you do that, MTP clients and any on-device apps that use MediaStore will see your files.
