I am trying to make an app that can track the GPS location of my bike. To start off, I've been trying to read the GPS location of my own phone. My app keeps crashing whenever I try to launch the fragment below. I have put in a Google API key for the App and placed the line " " in my manifest file. What are some good ways to debug this issue? I am new to Android Studio so I would love to hear any sort of feedback.

You need to use GoogleApiClient for FusedLocationApi.Here is a working code
protected synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();}
return;
}
Call buildGoogleApiClient method on onCreate().And implement required interfaces. GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener,
LocationListener
#Override
public void onConnected(#Nullable Bundle bundle) {
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling

// for ActivityCompat#requestPermissions for more details.
return;
}
Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
if (mLastLocation != null) {
//place marker at current position
// Log.e("x", mLastLocation.getLongitude() + "");
//Log.e("y", mLastLocation.getLatitude() + "");
currentLocation = mLastLocation;
}
LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(5000); //5 seconds
mLocationRequest.setFastestInterval(5000); //3 seconds
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
mLocationRequest.setSmallestDisplacement(50F); //1/10 meter
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
}
#Override
public void onConnectionSuspended(int i) {
}
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
}
#Override
public void onLocationChanged(Location location) {
currentLocation = location;
}
And define this parameters
private GoogleApiClient mGoogleApiClient;
private Location currentLocation;
Btw if you are using Android 6.x or 7.x version. You need to grant permission at runtime.Check here
#FnR you're talking about the old version of the fusedlocationapi, a new one came out with the version 11 of the playservices, it's supposed to be much simpler, look here : https://android-developers.googleblog.com/2017/06/reduce-friction-with-new-location-apis.html
I got the same issue there seems to be a conflict between the new fusedlocationapi and the map activities.
I'm able to get my current location with this new technique in an empty activity with no map but the exact same code used in a map activity returns a null result.
Google didn't even provide any example of this with a map, which is crazy since getting the location is 99% of the time coupled with a map

I am trying to display a users current location using the google map activity. when the activity is launched the google map is displayed as it should be, but there is no marker and the users current location is not gotten. The map displays a view over many different countries. After putting Toast messages in every method i realise onLocationChange is not being called, as no Toast appears for this method.

In order to display user location you should add:
mMap.setMyLocationEnabled(true);
on your onMapReady callback, there's no need to use a LocationRequest.
Be aware that you'll be able to get user position after your app has achieved location permissions. To do so you can follow this guide or use a third party library like easy permissions
After hours of research the answer was in front of me, the location settings were disabled in the phone settings. Witting this so the next person inst as stupid as me.

How can I move the camera on my current position, immediately when I open the app?
I have a button which works (if I click it, it move the camera on my current position), but when I open the app, the camera is set on the middle of the ocean.
I want to open the app and the camera is already set on my current position.

Thanks for your help.
So you have done almost all the work already. You just need to go one step further.
First to understand, setMyLocationEnabled when set to true adds that location compass button on the map. This is what you click to find your current location. Good start.
You also need to set the camera to your current location when you initialize the map.
if(locationPermissionGranted){
Task<Location> locationResult = fusedLocationProviderClient.getLastLocation();
locationResult.addOnCompleteListener(getActivity(), new OnCompleteListener<Location>() {
#Override
public void onComplete(#NonNull Task<Location> task) {
if(task.isSuccessful()){
// Set the maps camera to current location
lastKnownLocation = task.getResult();
map.moveCamera(CameraUpdateFactory.newLatLngZoom(
new LatLng(lastKnownLocation.getLatitude(), lastKnownLocation.getLongitude()), 12));
}
else{
Log.d(TAG, "Current location is null");
Log.e(TAG,"Exception: %s", task.getException());
map.moveCamera(CameraUpdateFactory.newLatLngZoom(defaultLocation, 12));
map.getUiSettings().setMyLocationButtonEnabled(false);
}
}
});
}
Try this. First make sure you have location permissions granted. Then try and find the last known location. (If you are using an emulator try opening Google Maps before trying this code. The location services on an emulator have never been initiated). It will try and grab your current location. If success it moves the camera to that location, if failed I have set a default location for the map to move to instead of opening in the ocean.
private LatLng defaultLocation = new LatLng(41.651031, -83.541939);
Hope this helps.
I think, I solved in this way.
I have modified my onMapReady:
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){
buildGoogleApiClient();
mMap.setMyLocationEnabled(true);
mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
#Override
public void onMyLocationChange(Location arg0) {
float zoomLevel = 15.0f;
LatLng latLng = new LatLng(arg0.getLatitude(), arg0.getLongitude());
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, zoomLevel));
}
});
}
/*disabling toolbar (it is used to continue using this app without having to
use the official google maps app)*/
mMap.getUiSettings().setMapToolbarEnabled(false);
Then, when I open my app, the camera is set on my current location.
Thanks a lot.
[Prerequisite] - Make sure you have location permission granted and location services is turned on.
public void onMapReady(GoogleMap googleMap){
mMap = googleMap;
// You can register for Location Change Once the location is updated,
// Fetch lat, lng from it. Once you have lat,lng convert it into `LatLng`
LatLng currLatLng = fetchedFromAPI();
CameraPosition newPos =
new CameraPosition.Builder()
.target(currLatLng)
.build();
if (showAnimation){
mMap.animateCamera(CameraUpdateFactory.newCameraPosition(newPos));
}else{
mMap.moveCamera(CameraUpdateFactory.newCameraPosition(newPos));
}
}
I'm getting errors for not extending AppCompatActivity.
How do I solve this?
I've market with HERE the places the errors are found
Can I replace the "this" with something else?
I have seen that you can make your own toolbar , would that work?

you can see the errors in this picure
You are using SupportMapFragment, so try with
getActivity() or getContext ().
getActivity()- Return the Activity this fragment is currently associated with.
getContext () Returns the context the view is running in, through which it can access the current theme, resources, etc.
Example
Toast.makeText(getContext(), "permission denied", Toast.LENGTH_LONG).show();
There is some issue in this code. I can find the current location of the user by this code but can't locate it on the Map. location is placed in lat, lang variables but onMapReady method lat, lang values are 0.

I think the problem can occur with any library you can find that use com.google.android.gms.
If you have references to com.google.android.gms in android/app/build.gradle.
Try giving the associated library a new version that you currently have installed.
I found the version number of the library I am using by navigating to [YOUR_ANDROID_SDK]/extras/google/m2repository/com/google/android/gms
Then find the library that might be causing you problems for example play-services-auth.
In there you will see all the versions. Apply the newest to your build.gradle.
compile 'com.google.android.gms:play-services:10.2.1'
Also add (It seems gcm is needed in GoogleApiClient Builder)
compile 'com.google.android.gms:play-services-gcm:10.2.1'
