Android - Get file path from URI gives error

Question

I am trying to get file path of an image from URI, but I am getting this error:

 Caused by: java.lang.IllegalArgumentException: Invalid URI: content://media/external/images/media/9298
   at android.provider.DocumentsContract.getDocumentId(DocumentsContract.java:917)

Here is the function that saves the image:

public Uri saveImage(Context context, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(context.getContentResolver(),
            inImage,
            DateTimeUtil.getDateTime(),
            null);
    return Uri.parse(path);
}

And here is the function that reads the file path of the image:

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

    String wholeID = DocumentsContract.getDocumentId(uri); <<<<<< ERROR HERE

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

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

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

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


    return filePath;
}
