What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 4 years ago.
In the below code, I am able to create a marker on the map. Whenever I try to run it with the runnable, I get the error stating to googleMap with the error as:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.journaldev.MapsInAction/com.journaldev.MapsInAction.MainActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'com.google.android.gms.maps.model.Marker com.google.android.gms.maps.GoogleMap.addMarker(com.google.android.gms.maps.model.MarkerOptions)' on a null object reference

How do I make sure that the code also updates the marker every 10 seconds? If the Runnable code is removed, it works perfectly with the marker shown. With the Runnable code, it crashes with the error above.
getMapAsync initialize Map asynchronously.
So when you call googleMap.addMarker() at first time in your Runnable it crashes because Map is not initialized yet and googleMap is null.
Easiest way to fix this is move periodicUpdate.run(); to onMapReady() callback
Also you must not forget to clean Runnable in onPause()
You are putting marker before map is initialized in runnable. That is why it is causing null pointer exception and crashing app. Putting a null pointer check will resolve this error. Try this:
#Override
public void run() {
handler.postDelayed(periodicUpdate, 10 * 1000 - SystemClock.elapsedRealtime() % 1000);
latitude += 0.01;
longitude += 0.01;
MarkerOptions a = new MarkerOptions()
.position(new LatLng(50, 6));
if (googleMap != null) {
Marker m = googleMap.addMarker(a);
}
m.setPosition(new LatLng(50, 5));
}
There are several issues with your code.
At first, it crashes because in periodicUpdate.run(); you try to create marker (Marker m = googleMap.addMarker(a);) by calling addMarker() on global private GoogleMap googleMap; object which is not initialized. It will be better if you rename private GoogleMap googleMap; to private GoogleMap mGoogleMap; and init mGoogleMap in onMapReady(GoogleMap googleMap) by mGoogleMap = googleMap nd than call addMarker() on it: Marker mGoogleMap = googleMap.addMarker(a);.
Also, you should get rid of two onMapReady() methods. And you should start call periodicUpdate.run(); inside onMapReady() because in other case its possible that the Marker m = mGoogleMap.addMarker(a); can be called before mGoogleMap was created. And you should declare Marker m as global (private Marker mMarker) for possibility to remove it before create updated marker. And seems you didn't update LatLng of marker... So, there are a lot of work...
You haven't initialed the variable googleMap yet. And before using googleMap, you have to make sure Google Map is ready. So follow this code:
private Runnable periodicUpdate = new Runnable() {
#Override
public void run() {
handler.postDelayed(periodicUpdate, 10*1000 - SystemClock.elapsedRealtime()%1000);
if(googleMap){
latitude+=0.01;
longitude+=0.01;
MarkerOptions a = new MarkerOptions()
.position(new LatLng(50,6));
Marker m = googleMap.addMarker(a);
m.setPosition(new LatLng(50,5));
}
}
};
#Override
public void onMapReady(GoogleMap googleMap)
{
this.googleMap = googleMap;
googleMap.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude))
.title("Bus Location")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude), 15));
}

I'm developing an application using Google Maps API.
I'm trying to add a marker where the user press on the map and to draw a line between markers that the user have created.
I'v tried to add the method SetOnMapClickListener but every time I run my application in the virtual device it's immediately crushes.
I've also tried to locate the method in OnCreate method and in OnMapReady, but this is not working either.
I succeeded to add new markers but only by writing them...
On some tutorials that I've found I saw that they assign the google map object with mapFragment.getMap(), but I don't have this method.
Thanks!
Here is my code:
package com.example.user.testmap;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
#Override
public void onMapClick(LatLng latLng) {
double lit = latLng.latitude;
double lon = latLng.longitude;
mMap.addMarker(new MarkerOptions().position(new LatLng(lit, lon)));
}
});
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
mMap.addMarker(new MarkerOptions().position(new LatLng(20, 5)));
mMap.moveCamera(CameraUpdateFactory.newLatLng(new LatLng(20, 5)));
}
}
try to remove your mMap.setOnMapClickListener in onCreate() then implements the GoogleMap.OnMapClickListener
like this.
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleMap.OnMapClickListener {
private GoogleMap mMap;
private ArrayList<Marker> arrMarkerList;
private ArrayList<Polyline> arrPolylineList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setOnMapClickListener(this);
arrMarkerList = new ArrayList<>();
arrPolylineList = new ArrayList<>();
}
#Override
public void onMapClick(LatLng latLng) {
double lit = latLng.latitude;
double lon = latLng.longitude;
arrMarkerList.add(mMap.addMarker(new MarkerOptions().position(new LatLng(lit, lon))));
// Removing the existing polyline to draw a new.
for (Polyline polyline : arrPolylineList) {
polyline.remove();
}
if (arrMarkerList.size() > 1) {
PolylineOptions polylineOptions = new PolylineOptions();
for (Marker marker : arrMarkerList) {
polylineOptions.add(marker.getPosition());
}
arrPolylineList.add(mMap.addPolyline(polylineOptions));
}
}
}

Closed 7 years ago.
I find a tutorial accroding getmap() in stackoverflow but it was for old version.
this is new offical google tutorial for create map:
public class mapmain extends FragmentActivity implements OnMapReadyCallback {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.primary_layout);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap map) {
// Add a marker in Sydney, Australia, and move the camera.
LatLng sydney = new LatLng(-34, 151);
map.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
map.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
how can I convert it to fragment class? (extend by fragment not FragmentActivity)

Use FragmentActivity instead of Activity

private GoogleMap map;
private Location location;
private ArrayList<LatLng> mLocationsLatLngList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_screen);
map = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.mapfragment)).getMap();
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(Your_CurrentLocation).zoom(13).bearing(0) // Sets the orientation of the camera to east
.tilt(30) // Sets the tilt of the camera to 30 degrees
.build(); // Creates a CameraPosition from the builder
map.setBuildingsEnabled(true);
map.setMyLocationEnabled(true);
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
}
}
xml -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:id="#+id/mapfragment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
class="com.google.android.gms.maps.SupportMapFragment" />
</LinearLayout>
You are using SupportMapFragment in the XML, so you must use getSupportFragmentManager instead of getFragmentManager.
Use this code to obtain the Fragment and the Map:
SupportMapFragment fr = (SupportMapFragment)this.getSupportFragmentManager().findFragmentById(R.id.mapfragment);
GoogleMap Map = fr.getMap();
Your Activity must extend FragmentActivity.
Im developing an app using Google Maps v2 for Android and I managed to put a custom icon to the user's position but I can't remove the default one, so it overlays my custom icon like in the image:
(It is that big just for now :p )
My code is like:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
map.setMyLocationEnabled(true);
map.setOnMyLocationChangeListener(new OnMyLocationChangeListener() {
#Override
public void onMyLocationChange(Location location) {
if (location == null)
return;
mPositionMarker = map.addMarker(new MarkerOptions()
.flat(true)
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.logop1))
.anchor(0.5f, 1f)
.position(new LatLng(location.getLatitude(), location.getLongitude())));
}
});
}
So:
1) Is there a way to remove the default blue dot of user's current location?
2) Will the user location be updated when I move in the "real world" (I cant test it for conectivity reasons) or do I have to write/override a method to update users position?
Thanks in advance
You will have to stop using GoogleMap.setMyLocationEnabled and write a bit more code, including having your own LocationClient and adding Circle for accuracy.
You have to do that on your own.
- set to false gmaps.getUiSettings().setMyLocationButtonEnabled(false);
create your own location button
if you get your current location, set a marker with your icon on that
if you click on your location button, move the camera and center it to the map
That will remove the blue dot
map.setMyLocationEnabled(true); remove line
