android - Google maps API v2 not working on device -


currently working on google maps , creating followed instructions in android developers site. cant load map in device, can point various places , all. device support google api v2? there way view map on device? device version 2.3.3.

i have working googlemaps v2 application , had same issues describe. problem in case api key used not matching certificate used sign application (debug/dev development phase , release play released app). application working on android versions 10 , on (so works on 2.3.3). log error sssems may having connectivity issue. did declare appropriate uses permissions? should be:

<uses-permission android:name="android.permission.internet"/> <uses-permission android:name="android.permission.access_coarse_location" /> <uses-permission android:name="android.permission.access_fine_location"/> 

here short snippet of main map code:

public class locationactivity extends mapactivity {       private mapcontroller mapcontroller;     private mapview mapview;     private locationmanager locationmanager;     private mylocationoverlay mylocationoverlay;      public void oncreate(bundle bundle) {         super.oncreate(bundle);         if(utils.isrelease(getapplicationcontext())) {             setcontentview(r.layout.location_activity_release); // bind layout activity         } else {             setcontentview(r.layout.location_activity); // bind layout activity         }          // configure map         mapview = (mapview) findviewbyid(r.id.mapview);         mapview.setbuiltinzoomcontrols(true);         mapview.setsatellite(false);         mapcontroller = mapview.getcontroller();         mapcontroller.setzoom(15); // zoon 1 world view          mylocationoverlay = new mylocationoverlay(this, mapview);         mapview.getoverlays().add(mylocationoverlay);         // more map configurations follow... 

and layouts (notice difference in maps api key): location_activity.xml

<?xml version="1.0" encoding="utf-8"?> <com.google.android.maps.mapview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/mapview"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:apikey="@string/google_maps_v1_api_key"     android:clickable="true" />  

and (location_activity_release.xml):

<?xml version="1.0" encoding="utf-8"?> <com.google.android.maps.mapview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/mapview"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:apikey="@string/google_maps_v1_api_key_release"     android:clickable="true" />
