Convert file: Uri to File in Android

What is the easiest way to convert from an android.net.Uri object which holds a file: type to a java.io.File object in Android?

I tried the following but it doesn't work:

File file = new File(Environment.getExternalStorageDirectory(), "read.me");
Uri uri = Uri.fromFile(file);
File auxFile = new File(uri.toString());
assertEquals(file.getAbsolutePath(), auxFile.getAbsolutePath());
Solution

  • What you want is...

    new File(uri.getPath());

    ... and not...

    new File(uri.toString());
    Notes
    1. For an android.net.Uri object which is named uri and created exactly as in the question, uri.toString() returns a String in the format "file:///mnt/sdcard/myPicture.jpg", whereas uri.getPath() returns a String in the format "/mnt/sdcard/myPicture.jpg".
    2. I understand that there are nuances to file storage in Android. My intention in this answer is to answer exactly what the questioner asked and not to get into the nuances.
