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

private static String FILE_NAM  = "video";
String outputfile = getFilesDir() + File.separator+FILE_NAM+"_tmp.mp4";

InputStream in = getContentResolver().openInputStream(videoFileUri);
private static File createFileFromInputStream(InputStream inputStream, String fileName) {

    try {
        File f = new File(fileName);
        f.setWritable(true, false);
        OutputStream outputStream = new FileOutputStream(f);
        byte buffer[] = new byte[1024];
        int length = 0;

        while((length=inputStream.read(buffer)) > 0) {
            outputStream.write(buffer,0,length);
        }

        outputStream.close();
        inputStream.close();

        return f;
    } catch (IOException e) {
        System.out.println("error in creating a file");
        e.printStackTrace();
    }

    return null;
}
