Android谷歌地图，谷歌地点，北纬超过南纬

Question

我正在使用谷歌地图并使用 JSON 从谷歌地点解析我所在位置周围的咖啡馆。当我从当前位置 95% cafe 开始导航到所选咖啡馆时，我得到一条折线，但在某些地方我收到错误，例如北纬超过南纬和应用程序崩溃。

这是我的日志:

利用 LatLngBounds.Builder 类使用 .include() 包含您的 LatLng。它将防止此错误。

LatLngBounds.Builder builder = new LatLngBounds.Builder();
builder.include(currentLocation).include(streetLocation);

//Animate to the bounds
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngBounds(builder.build(), 100);
mMap.moveCamera(cameraUpdate);
