将exoplayer 2.8.4迁移到2.9.0

Question

我试图将exoplayer 2.8.4更新到2.9.0。 但是现在我在编译过程中遇到了这个错误：

Traceback (most recent call last):


File "C:\Users\hermans\Desktop\RedditBot\Current_Create_DB.py", line 121, in <module>
    row = json.loads(row)
  File "C:\Program Files (x86)\Python 3.5\lib\json\__init__.py", line 319, in loads
    return _default_decoder.decode(s)
  File "C:\Program Files (x86)\Python 3.5\lib\json\decoder.py", line 339, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Program Files (x86)\Python 3.5\lib\json\decoder.py", line 355, in raw_decode
    obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 2 column 1 (char 2)

这是我完整的gradle文件： https://pastebin.com/e2DKAvmF

对这个问题有任何想法吗？

感谢您的帮助。
