i want to choose a file (via file chooser) from astro manager (in my case a *.pdf or *.doc) but the uri contains only the file path (\"sdcard/my_folder/test.pdf\"

    Like @CommmonsWare said, there is no easy way to convert any type of files into content:// .
    But here is how I convert an image File into content://

    public static Uri getImageContentUri(Context context, File imageFile) {
        String filePath = imageFile.getAbsolutePath();
        Cursor cursor = context.getContentResolver().query(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                new String[] { MediaStore.Images.Media._ID },
                MediaStore.Images.Media.DATA + "=? ",
                new String[] { filePath }, null);
    
        if (cursor != null && cursor.moveToFirst()) {
            int id = cursor.getInt(cursor
                    .getColumnIndex(MediaStore.MediaColumns._ID));
            Uri baseUri = Uri.parse("content://media/external/images/media");
            return Uri.withAppendedPath(baseUri, "" + id);
        } else {
            if (imageFile.exists()) {
                ContentValues values = new ContentValues();
                values.put(MediaStore.Images.Media.DATA, filePath);
                return context.getContentResolver().insert(
                        MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
            } else {
                return null;
            }
        }
    }
