Answer 1

Make use of LatLngBounds.Builder class to include your LatLng using .include(). It will prevent this error.

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);

Answer 2

First , I'am Chinese ,and I use the Gaode Map（aMap.com）,and while I run this

aMap.addPolyline(new
PolylineOptions().add(drawLineLastLatlng,latlng).width(10)            
.color(Color.argb(255, 1, 255, 255)))

the Exception "southern latitude exceeds northern latitude" occurs; then I check the class and find the sentence at LineNumber 35, then I change my codes like this ,and questions resolved :

if(drawLineLastLatlng!=null&&drawLineLastLatlng.latitude!=latlng.latitude){                                               
                if(latlng.latitude>drawLineLastLatlng.latitude){
                    aMap.addPolyline(new PolylineOptions().add(drawLineLastLatlng,latlng).width(10)
                            .color(Color.argb(255, 1, 255, 255)));
                }else{
                    aMap.addPolyline(new PolylineOptions().add(latlng,drawLineLastLatlng).width(10)
                            .color(Color.argb(255, 1, 255, 255)));
                }
            }

This exception basically happens while creating LatLngBounds object with wrong LatLng points. southwest Latlong should be first and northwest should be 2nd parameter. check this link
