Android: how to get audio data from an audio file

I have a music application that runs from external applications using intent data as a music file.

So I have an mp3 audio URI something like this

File: /// storage / emulate / 0 / Music / Tamil / I% 20 ​​(2014) /Ennodu%20Nee%20Irundhaal.mp3

how to get audio data from a URI, i.e. Media.TITLE, Media.ALBUM, Media._ID

You can convert the file URI to the canonical path and retrieve information about the music file using the ContentProvider, as shown below.

String path = new File(new URI(path).getPath()).getCanonicalPath();
Cursor c = context.getContentResolver().query(
    MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
    new String[] {
            MediaStore.Audio.Media.ALBUM,
            MediaStore.Audio.Media.ARTIST,
            MediaStore.Audio.Media.TRACK,
            MediaStore.Audio.Media.TITLE,
            MediaStore.Audio.Media.DISPLAY_NAME,
            MediaStore.Audio.Media.DATA,
            MediaStore.Audio.Media.DURATION,
            MediaStore.Audio.Media.YEAR
    },
    MediaStore.Audio.Media.DATA + " = ?",
    new String[] {
            path
    },
    "");

if (null == c) {
    // ERROR
}

while (c.moveToNext()) {
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.ALBUM));
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.ARTIST));
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.TRACK));
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.TITLE));
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.DATA));
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.DURATION));
    c.getString(c.getColumnIndex(MediaStore.Audio.Media.YEAR));
}
