google maps - Unable to get current location problems (android, permission) -
i've dev first application , make simple map activity, latitude , longitude 0. (when start activity cursor should set in device location). set permission in manifest , google-services.json file, still have error:
e/gmpm: googleservice failed initialize, status: 10, missing expected resource: 'r.string.google_app_id' initializing google services. possible causes missing google-services.json or com.google.gms.google-services gradle plugin.
i think why cant correct longitude , latitude.
activity code:
public class ********activity extends fragmentactivity implements onmapreadycallback,googleapiclient.connectioncallbacks, googleapiclient.onconnectionfailedlistener { private googlemap mmap; double latitude, longitude; googleapiclient mgoogleapiclient; location mlastlocation; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_locate_match); buildgoogleapiclient(); if (mgoogleapiclient != null) { mgoogleapiclient.connect(); } else toast.maketext(this, "not connected...", toast.length_short).show(); // obtain supportmapfragment , notified when map ready used. supportmapfragment mapfragment = (supportmapfragment) getsupportfragmentmanager() .findfragmentbyid(r.id.map); mapfragment.getmapasync(this); } protected void onstart() { mgoogleapiclient.connect(); super.onstart(); } protected void onstop() { mgoogleapiclient.disconnect(); super.onstop(); } public void onconnectionfailed(connectionresult arg0) { toast.maketext(this, "failed connect...", toast.length_short).show(); } public void onconnectionsuspended(int arg0) { toast.maketext(this, "connection suspended...", toast.length_short).show(); } public void onconnected(bundle arg0) { mlastlocation = locationservices.fusedlocationapi.getlastlocation(mgoogleapiclient); if (activitycompat.checkselfpermission(this, manifest.permission.access_fine_location) != packagemanager.permission_granted){ // todo: consider calling // activitycompat#requestpermissions // here request missing permissions, , overriding // public void onrequestpermissionsresult(int requestcode, string[] permissions, // int[] grantresults) // handle case user grants permission. see documentation // activitycompat#requestpermissions more details. log.i("permission","problems"); return; } if (mlastlocation != null) { latitude = mlastlocation.getlatitude(); longitude = mlastlocation.getlongitude(); log.i("latitude",""+latitude); log.i("longitude",""+longitude); } } protected synchronized void buildgoogleapiclient() { mgoogleapiclient = new googleapiclient.builder(this) .addconnectioncallbacks(this) .addonconnectionfailedlistener(this) .addapi(locationservices.api) .build(); } /** * manipulates map once available. * callback triggered when map ready used. * can add markers or lines, add listeners or move camera. in case, * add marker near sydney, australia. * if google play services not installed on device, user prompted install * inside supportmapfragment. method triggered once user has * installed google play services , returned app. */ @override public void onmapready(googlemap googlemap) { mmap = googlemap; latlng pos = new latlng(latitude,longitude); mmap.addmarker(new markeroptions().position(pos).title("user marker")); mmap.movecamera(cameraupdatefactory.newlatlng(pos)); } } manifest:

you need place configuration file (google-services.json) generated developer.google.com, mentioned in 2nd step of official docs here
