Unable to view googlemap in Maps activity

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));

Unable to get current location problems (android, permission)

I've dev my first application and i make a simple map activity, but latitude and longitude are always 0. (when i start the activity the cursor should be set in the device location).
I set permission in manifest and get google-services.json file, but i still have this error:
E/GMPM: GoogleService failed to initialize, status: 10, Missing an expected resource: 'R.string.google_app_id' for initializing Google services. Possible causes are missing google-services.json or com.google.gms.google-services gradle plugin.
I think this is why I cant get correct longitude and latitude.

Reading the log, i saw "Permission:problems" so the app seems to not has the right permission.

You need to place the configuration file (google-services.json) generated by developer.google.com, as mentioned in the 2nd step of the official docs here
Please take a look at this post: GoogleService failed to initialize
It will help you

I think i solved my problem:
- i updated android studio and now i use
compile 'com.google.android.gms:play-services-maps:9.2.0'
compile 'com.google.android.gms:play-services:9.2.0'
instead of 8.4.0.
Now i'll create a new post, cause i'm going crazy to use maps

Show location on map from address

I want to show user location as per address submitted by him. For that i am using Geocoder. But i got following error.

You need to add the package name and SHA certificate fingerprint on the developers console, under your key. Have you done that?

You need to add map key to show googlemap on your application.I didn't see it in the manifest file,i see only key for using GeoCoder
Try after adding your google map key. Example is shown below
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />

Try this, it may help you:
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocationName("Location String", 1);
} catch (IOException e) {
e.printStackTrace();
}
Address address = addresses.get(0);
if(addresses.size() > 0) {
double latitude = addresses.get(0).getLatitude();
double longitude = addresses.get(0).getLongitude();
LatLng latLng = new LatLng(latitude, longitude);
mMap.addMarker(new MarkerOptions().position(latLng));
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
mMap.animateCamera(CameraUpdateFactory.zoomTo(10));
}

Google map not coming despite no errors

I am trying to load google map in emulator for a given latitude and longitude.
Map is loading in the emulator but no marker is coming and same view is shown always.
i have followed the tutorial. Below is my code.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
double latitude = getIntent().getDoubleExtra("lat", 0);
double longitude = getIntent().getDoubleExtra("lng", 0);
Log.d("Zumbare","lat value : "+latitude);
Log.d("Zumbare","lng value : "+longitude);
LatLng position = new LatLng(latitude, longitude);
MarkerOptions options = new MarkerOptions();
options.position(position);
options.title("Position");
options.snippet("Latitude:"+latitude+",Longitude:"+longitude);
options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN));
SupportMapFragment fm = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap googleMap = fm.getMap();
googleMap.setMyLocationEnabled(true);
googleMap.getUiSettings().setMyLocationButtonEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(true);
googleMap.getUiSettings().setCompassEnabled(true);
googleMap.addMarker(options);
CameraUpdate updatePosition = CameraUpdateFactory.newLatLng(position);
CameraUpdate updateZoom = CameraUpdateFactory.zoomBy(4);
googleMap.moveCamera(updatePosition);
googleMap.animateCamera(updateZoom);

Can someone help me where the problem is..
Edit :
Yes, I am fetching lat lng of a city and logs are coming as..
1885-1885/com.app.maptest.gmap D/Zumbare﹕ lat value : 16.506174
03-29 16:20:54.602 1885-1885/com.app.maptest.gmap D/Zumbare﹕ lng value : 80.648015
Edit2:
I am using android studio and added the google play service in gradle file as below.
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.google.android.gms:play-services:3.1.36'
}

I think the tutorial that you followed is outdated. play-services now is 6.5.87.
Please try to follow this step by step, you will finally get a map on your phone.
MainAcitivity, sample code:
public class MainActivity extends Activity {
private static LatLng goodLatLng = new LatLng(37, -120);
private GoogleMap googleMap;
private EditText et_address, et_finalAddress;
LatLng addressPos, finalAddressPos;
Marker addressMarker;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_address = (EditText) findViewById(R.id.addressEditText);
et_finalAddress = (EditText) findViewById(R.id.finalAddressEditText);
// Initial Map
try {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
}
} catch (Exception e) {
e.printStackTrace();
}
googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
// Put a dot on my current location
googleMap.setMyLocationEnabled(true);
googleMap.setIndoorEnabled(true);
googleMap.setTrafficEnabled(true);
// 3D building
googleMap.setBuildingsEnabled(true);
// Get zoom button
googleMap.getUiSettings().setZoomControlsEnabled(true);
Marker marker = googleMap.addMarker(new MarkerOptions()
.position(goodLatLng)
.title("Hello"));
}
For more details, please refer to my github here.

Old MapView has been depreciated. You can't create a new Map key for publishing your app.
You have to use new Google Maps for Android v2 API. Here's a link to the documents and example.
https://developers.google.com/maps/documentation/android/start

make sure Google Repository && Google play Services is up to Date
add below to Project level Gradle
classpath 'com.google.gms:google-services:3.0.0'
and below two statements to App Level Gradle
compile 'com.google.android.gms:play-services-location:11.0.1'//for location
compile 'com.google.android.gms:play-services-maps:11.0.1'//for maps
compile 'com.google.android.gms:play-services-places:11.0.1'//for places
And add permission in Manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
add below statment in tag
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<meta-data

I could do this with the Google Map Activity bundled with Android Studio 1.2.1.1. I created a Google Maps Activity and followed the instructions as below:
Created the API Key following the instructions in google_maps_api.xml
To get one, follow this link, follow the directions and press "Create" at the end:
https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY%3Bnpackagename
You can also add your credentials to an existing key, using this line:
XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY;newmapscreen.avapps.nbapl.com.newmapscreen
Once you have your key (it starts with "AIza"), replace the "google_maps_key"
string in this file.
-->
<string name="google_maps_key" translatable="false" templateMergeStrategy="preserve">
AIzaXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
</string>
After that, I ensured all the dependencies are there in Android Manifest, build.gradle. See this answer for details.
In your MapActivity.java, you can add additional markers, and use the Android Google Maps API V2 features to enhance your map.
(replace XY:XY ...with whats in your google_maps_api.xml)
