How to check sign error when developing Android Tencent Weibo with a real machine

Everything works normally when using a simulator;

When using a real machine, {"data": NULL, "errcode":-103, "MSG": "check sign error", "RET": 3} returned values always appear.

Later I considered whether it was an HTTPS problem, but I found that all of them were connected over HTTP.

What are the differences between a real machine and a simulator?

It suddenly occurred that there was a timestamp in the parameter and the local time was to be read, and the difference between the time and the server cannot be greater than 8 minutes.

So I checked the Android phone and found that the time of the phone was automatically set by the network,

And the time zone is GMT + 0.

My God, the difference is 8 hours.

Change it back.

So everything is normal.

We hope that the returned values of the API can be clear, saving our developers time.
