update:

ok seems problem location manager (returning null) :

locman = (locationmanager) getsystemservice(location_service);     criteria criteria = new criteria();     provider = locman.getbestprovider(criteria, false);     loc = locman.getlastknownlocation(provider); 

manifest

    <uses-permission android:name="android.permission.access_network_state" /> <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" /> <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices" /> <uses-permission android:name="android.permission.get_accounts" /> <uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="com.google.android.c2dm.permission.receive" /> <uses-permission android:name="android.permission.vibrate" /> <uses-permission android:name="android.permission.wake_lock" /> 

ok locationmanager not getting location.

any appreciated. im stressing.

can see grids in mapview.if yes may not getting location.but if not getting , application crashes,check manifest following

<uses-library android:name=”com.google.android.maps” />
