Error description

To the enterprise to do the app embedded in the use of GPS address information into the actual address of the function, using the Baidu map of the geocoding function, from the beginning of Wednesday, there have been user feedback, using the location can not obtain address information error, a small range, it is the user's own problems, no care , but in the Thursday, it began to explode in large areas;

Solution to find out whether the Baidu API changes

Because the recent Android app did not do any updates, so the suspicion is not Baidu's API has been modified, but looked at the following document, also did not change, and according to Baidu before the habit should be backward compatible;

See if the key expires.

Login Baidu Map API management Console, see the next key is not expired, and through the code can also be accessed;

After the key has been replaced, the problem remains after the call;

Check Android code

1, check the code used for the downgrade, found that the use of HttpGet way to obtain, consider changing the post method to see if it can solve the problem;

2, replaced by HttpPost mode, the problem is resolved, you can confirm that Baidu modified the API to obtain the way, rejected the get way live rejected Android code inside HttpGet Way;

&NBSP;

&NBSP;

3, but modified to post method, found that there will be 10 calls, 3 times will appear to fail, re-check the code, found that the practical way is not httppost, replaced by the standard way, the problem is resolved;

Change the revision here to

Basicnamevaluepair Basevaluepair = new Basicnamevaluepair ("Output", "json");

Params.add (Basevaluepair);

Basevaluepair = new Basicnamevaluepair ("Location", Loc.getlatitude () + "," +loc.getlongitude ());

strresult = Httpcomm.posturldata (method_url,params);
