Android: save a file from an existing URI

Question

How to save a media file (say .mp3) from an existing URI, which I am getting from an Implicit Intent?

Answer 1

Here's the easiest and the cleanest:

private void saveFile(Uri sourceUri, File destination)
    try {
        File source = new File(sourceUri.getPath());
        FileChannel src = new FileInputStream(source).getChannel();
        FileChannel dst = new FileOutputStream(destination).getChannel();
        dst.transferFrom(src, 0, src.size());
        src.close();
        dst.close();
    } catch (IOException ex) {
        ex.printStackTrace();
    }
}
