回调中修改，也会出问题，报错如下

Start by tracing the callback stack from com._.activity.cb_CF.onSuccess(x.java:93) through AbstractRestClient.java:241 and JsonHttpResponseHandler.java:126. Reproduce the Android callback scenario and determine why it raises the reported NoSuchFieldError; done means the same callback completes without that error.
