I am doing a simple app that has to do with maps in Android studio. When I run it with the release key,
keytool -list -v -keystore C:\Users\Theodosios\maps.jks -alias mapsalias -storepass
larissa -keypass larissa
the map doesn't run correctly. If I use the debug.kestore though everything works fine.The message in the output is
01-06 00:17:00.904: E/ActivityThread(1665):

I took the code code of the MainActivity from google.It's pretty straight forward.
public class MainActivity extends ActionBarActivity {
GoogleMap googleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
createMapView();
addMarker();
}
/**
* Initialises the mapview
*/
private void createMapView(){
/**
* Catch the null pointer exception that
* may be thrown when initialising the map
*/
try {
if(null == googleMap){
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.mapView)).getMap();
/**
* If the map is still null after attempted initialisation,
* show an error to the user
*/
if(null == googleMap) {
Toast.makeText(getApplicationContext(),
"Error creating map", Toast.LENGTH_SHORT).show();
}
}
} catch (NullPointerException exception){
Log.e("mapApp", exception.toString());
}
}
private void addMarker(){
/** Make sure that the map has been initialised **/
if(null != googleMap){
Marker marker1= googleMap.addMarker(new MarkerOptions()
.position(new LatLng(39.648141,22.413155))
.title("Marker")
.draggable(true)
);
}
}
}
In the manifest file I add the necessary permissions.

Any help/hint will save my day

Valid=FALSE Implies your device does not have a GPS lock. Is your device indoors and unable to obtain a position? Second, please check to see if your application has the positioning permission.
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION " />
I am trying to build a location based MAP app and when I try to execute my App, I can view my Markers added to the Mapsactivity, however i don't Map on the activity
I can confirm that I have provide the correct Map key for my activity getting the key from console.developer.com and enabling Google Maps for Android API
Please suggest what could be wrong here

Probably you show desert on the map.
Try change:
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(mLat,mLon), 20));
to
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(mLat, mLon), 5));

I am creating class of map activity below, I have created the PositioningManager.getInstance() it gives null object by Toast popup
public class MainActivity extends AppCompatActivity {
// map embedded in the map fragment
private Map map = null;
// map fragment embedded in this activity
private MapFragment mapFragment = null;
private PositioningManager positioningManager = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Positioning Manager
positioningManager = PositioningManager.getInstance();
if (positioningManager == null) {
Toast.makeText(MainActivity.this, " Positioning Null", Toast.LENGTH_LONG).show();
}
// Search for the map fragment to finish setup by calling init().
mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.mapfragment);
mapFragment.init(new OnEngineInitListener() {
#Override
public void onEngineInitializationCompleted(
OnEngineInitListener.Error error) {
if (error == OnEngineInitListener.Error.NONE) {
// retrieve a reference of the map from the map fragment
map = mapFragment.getMap();
// Set the map center to the Vancouver region (no animation)
map.setCenter(new GeoCoordinate(12.9172, 77.5738, 0.0),
Map.Animation.NONE);
// Set the zoom level to the average between min and max
map.setZoomLevel(
(map.getMaxZoomLevel() + map.getMinZoomLevel()) / 2);
} else {
System.out.println("ERROR: Cannot initialize Map Fragment");
Toast.makeText(MainActivity.this, "Error:" + error.toString(), Toast.LENGTH_LONG).show();
}
}
});
}
}
Everything that's HERE Maps related needs to happen after initialization. This is applicable for everything related to the HERE MobileSDK.
Try getting the PositioningManager inside your EngineInitListener.onEngineInitializationCompleted (and keep in mind, once you get the instance, you also have to call start on it to receive any events)
So i just created a new google maps activity and it gives me a null pointer exception if i try to run my application
private GoogleMap mMap; // Might be null if Google Play services APK is not available.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setUpMapIfNeeded();
}
#Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
private void setUpMap() {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}
}
}

You need to call in onCreate(): setContentView(R.layout.main_layout).
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
setUpMapIfNeeded();
}
Please make sure that you extend ActionBarActivity
public class Contact_Us extends ActionBarActivity {
private GoogleMap mMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_us);
setUpMapIfNeeded();
}
