In GPS devices, there are different display methods for coordinate units, with degrees (DMS) and degrees (DDD ).
For example, the GPS coordinates of the window Pioneer Park in bancang Street, Xuanwu District, Nanjing are as follows:
Minute second (DMS): longitude E 118 degrees 48 minutes 54.152 seconds north latitude N 32 degrees 04 minutes 10.461 seconds
Degree (DDD): E 118.815033 degrees N 32.069723 degr
First, open the simulator.

To convert the GPS coordinates collected by mobile phones to Baidu coordinates, I found the code on the Internet:
GeoPointgeoPoint3=newGeoPoint((int)((mLat1+0.001)*1E6),(int)((mLon1+0.003)*1E6));GeoPointGeoPointBaidu=CoordinateConvert.fromWgs84ToBaidu(geoPoint3);mOverlayList.add(newOverlayItem(GeoPointBaidu,"point","point"));A crash occurs as soon as it is run, and an error is displayed: 10-08
