android - Map Fragment doesn't load with same GPS location and Map Type -

i'm new android programming. i'm working on android project need access google maps. i've navigation drawer couple of options include google map location too.

so whenever try load map first time works fine , loads map current gps location , map type defined.

but whenever try switch other fragment , come map fragment, gps function , map type doesn't work.

help needed. in advance. i'm trying possible fix it. :)

my code below.

what i'm trying here whenever user touches somewhere, marker placed on location.

 public class addcustomerlocationfragment extends fragment implements         locationlistener {      private mapview mapview;     private googlemap map;     private marker marker;     private boolean markeravailable;     private bundle bundle;     button btnreset, btnsetlocation;     locationmanager locationmanager;     private view view;     private double[] addcustomerlocation = new double[10];      @override     public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {      view v = inflater.inflate(r.layout.fragment_addcustomer_location,      container, false);      mapsinitializer.initialize(getactivity());      mapview = (mapview) v.findviewbyid(r.id.map);      btnreset = (button) v.findviewbyid(r.id.btnreset);      btnsetlocation = (button) v.findviewbyid(r.id.btnsetlocation);      mapview.oncreate(bundle);      map.setmylocationenabled(true);      locationmanager = (locationmanager) getactivity()      .getsystemservice(      context.location_service);       if (locationmanager.isproviderenabled(locationmanager.gps_provider)) {      getgps();      } else {      locationmanager.requestlocationupdates(      locationmanager.network_provider, 1000, 10, this);      }      map.setmaptype(googlemap.map_type_hybrid);      map.getuisettings().setmylocationbuttonenabled(true);      map.getuisettings().setcompassenabled(true);       map.setonmapclicklistener(new onmapclicklistener() {      public void onmapclick(latlng point) {      toast.maketext(      getactivity(),      "latitude:" + point.latitude + ", longitude:"      + point.longitude, toast.length_short).show();      addmarker(point);      markeravailable = true;      }      });      btnsetlocation.setonclicklistener(new onclicklistener() {       @override      public void onclick(view v) {      // todo auto-generated method stub      toast.maketext(      getactivity(),      "your current loaction set to: latitude:"      + addcustomerlocation[0] + ", longitude:"      + addcustomerlocation[1], toast.length_short)      .show();       }      });      btnreset.setonclicklistener(new onclicklistener() {       @override      public void onclick(view v) {      // todo auto-generated method stub      marker.remove();      toast.maketext(getactivity(), "marker reset",      toast.length_short).show();      markeravailable = false;      }      });       // add marker      //      return v;      }     private void getgps() {         // todo auto-generated method stub         onlocationchanged(locationmanager                 .getlastknownlocation(locationmanager.passive_provider));      }      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         bundle = savedinstancestate;         setretaininstance(true);     }      @override     public void onresume() {         super.onresume();         mapview.onresume();         getgps();     }      @override     public void onpause() {         super.onpause();         mapview.onpause();     }      private void outgps() {         // todo auto-generated method stub         locationmanager.removeupdates(this);      }      @override     public void ondestroy() {         mapview.ondestroy();         super.ondestroy();     }      @override     public void onlowmemory() {         super.onlowmemory();         mapview.onlowmemory();     }      // @override     public void onlocationchanged(location location) {          // todo auto-generated method stub         latlng latlng = null;         if (!markeravailable) {             latlng = new latlng(location.getlatitude(), location.getlongitude());             cameraupdate cameraupdate = cameraupdatefactory.newlatlngzoom(                     latlng, 18f);             map.animatecamera(cameraupdate);             addmarker(latlng);     }      @override     public void onproviderdisabled(string provider) {         // todo auto-generated method stub      }      @override     public void onproviderenabled(final string provider) {         // todo auto-generated method stub     }      @override     public void onstatuschanged(string provider, int status, bundle extras) {         // todo auto-generated method stub      }      private void addmarker(latlng point) {         map.clear();         marker = map.addmarker(new markeroptions().position(                 new latlng(point.latitude, point.longitude)).title(                 "your location!?"));     } } 

here code display google map within fragment. i've put onlongclicklisteners place markers on map, can change onclick.

i've added fragment mainactivity.

you need add permissions manifest , specify google maps api key. manifest file is:

<?xml version="1.0" encoding="utf-8"?> <manifest package="your_package"           xmlns:android="http://schemas.android.com/apk/res/android">      <uses-permission android:name="android.permission.internet"/>     <uses-permission android:name="android.permission.access_network_state"/>     <uses-permission android:name="android.permission.write_external_storage"/>     <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices"/>     <!--  access_coarse/fine_location permissions not required use          google maps android api v2, recommended.     -->     <uses-permission android:name="android.permission.access_coarse_location"/>     <uses-permission android:name="android.permission.access_fine_location"/>      <permission         android:name="com.arshad.map.permission.maps_receive"         android:protectionlevel="signature"/>      <!-- permission receive google maps -->     <uses-permission android:name="com.arshad.map.permission.maps_receive"/>      <!-- maps api needs opengl es 2.0. -->     <uses-feature         android:glesversion="0x00020000"         android:required="true"/>      <application         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme">         <meta-data             android:name="com.google.android.gms.version"             android:value="@integer/google_play_services_version"/>         <meta-data             android:name="com.google.android.maps.v2.api_key"             android:value="@string/google_maps_key"/>          <activity             android:name=".mainactivity"             android:label="@string/title_activity_main">             <intent-filter>                 <action android:name="android.intent.action.main"/>                  <category android:name="android.intent.category.launcher"/>             </intent-filter>         </activity>     </application>  </manifest> 

and you're go.
