[android] android get real path by Uri.getPath()

EDIT: Use this Solution here: https://stackoverflow.com/a/20559175/2033223 Works perfect!

First of, thank for your solution @luizfelipetx

I changed your solution a little bit. This works for me:

public static String getRealPathFromDocumentUri(Context context, Uri uri){
    String filePath = "";

    Pattern p = Pattern.compile("(\\d+)$");
    Matcher m = p.matcher(uri.toString());
    if (!m.find()) {
        Log.e(ImageConverter.class.getSimpleName(), "ID for requested image not found: " + uri.toString());
        return filePath;
    }
    String imgId = m.group();

    String[] column = { MediaStore.Images.Media.DATA };
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ imgId }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();

    return filePath;
}

Note: So we got documents and image, depending, if the image comes from 'recents', 'gallery' or what ever. So I extract the image ID first before looking it up.
