Not sure why this is happening, the application shows no errors and I've obtained the key successfully as well but the activity doesn't run!

Please keep in mind that I have read through the hundreds of similar questions such as this but I've seemed to cross off the check list of everything that has been stated in the instructions on how to get the Google maps to start working.
First things first, I'll show my code, then I'll narrate what has been happening.

Familiar right? You see it in a lot of other questions. I think what differentiates my question from the others is I may have a problem with different flavors of my app.
To cross out the mistakes others have encountered, I have done the following:
- Made sure my api keys are inside the tag of the manifest file.
- Ensured that the Google Maps API v2 for Android is enabled on Google Consoles
- I'm using the Google Play Services via Gradle (Scroll down for my gradle snippet)
- I made sure all of the essential permissions are set
- I made sure to enable the glEsVersion.
What I think the problem is?
I think I'm having a problem with my "free.elephant.tuskapp" flavor to authenticate with googles servers. In my gradle build, I maintain two different flavors of my application and I seem to be getting an error with authentication:
Ensure that the "Google Maps Android API v2" is enabled.
Ensure that the following Android Key exists:
API Key: myAPIKEY
Android Application (<cert_fingerprint>;<package_name>): SHA-1;free.elephant.tuskapp
I obtained my API by using the 'elephant.tuskapp' package name rather than the 'free.elephant.tuskapp'
Here's my gradle build if it's of any help:
Gradle
buildscript {
repositories {
maven {
url 'https://maven.fabric.io/public'
}
}
dependencies {
classpath 'io.fabric.tools:gradle:1.+'
}
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
repositories {
maven {
url 'https://maven.fabric.io/public'
}
}
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc2"
defaultConfig {
applicationId "elephant.tuskapp"
minSdkVersion 15
targetSdkVersion 15
}
productFlavors {
demo {
applicationId "demo.elephant.tuskapp"
}
free {
applicationId "free.elephant.tuskapp"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.google.android.gms:play-services:7.5.0'
compile 'com.google.zxing:core:3.2.0'
compile('com.crashlytics.sdk.android:crashlytics:2.3.2#aar') {
transitive = true;
}
}
Am I missing out on something? Or does it really have something to do with my flavor builds? If it's the flavors causing trouble, how am I supposed to handle this? I generated new api keys for all my flavors but I don't see how I'm supposed to make that work within the manifest file as well as having it look elegant.
According to your logcat, it says something wrong with your Map fragment layout. Also, I find that there is nothing in your MainActivity, I think you should initial map there. For more details, you can refer code here.
Sample code:
public class MainActivity extends FragmentActivity {
GoogleMap mGoogleMap;
private static LatLng MountainView = new LatLng(37.42, -122.08);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initial Map
try {
if (mGoogleMap == null) {
mGoogleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
}
} catch (Exception e) {
e.printStackTrace();
}
mGoogleMap.getUiSettings().setMyLocationButtonEnabled(true);
mGoogleMap.getUiSettings().setZoomControlsEnabled(true);
mGoogleMap.getUiSettings().setZoomGesturesEnabled(true);
mGoogleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(MountainView, 15));
Marker marker = mGoogleMap.addMarker(new MarkerOptions()
.position(MountainView)
.title("Have a nice day!"));
}
}
Since my app has multiple flavors, I was getting thrown an error that my api-keys were not being validated. The way to resolve this is to ensure that you add all packages of your project into the Google Developer Console.
SHA1;packagename
Then press enter
SHA1;packagename2(flavor)
In my case it was:
SHA1;elephant.tuskapp
SHA1;free.elephant.tuskapp
SHA1;demo.elephant.tuskapp
Im almost just a beginner in android. I was trying to make a very simple app with google maps, ie just displaying maps. I followed the following link:
file:///C:/Android/Android%20Google%20Maps%20V2%20Tutorial.htm
But when I test it on my device it says it has stopped working and closes.
Here is my Manifest.xml:

I have googled a lot about it and got some direct questions on it but no answer ?? .
It seems many have the same problem.Can anyone help with this problem. I want to develop an app but not able to proceed as Google mpas api is main part of it.
Your are missing a meta tag in the application tag of manifest
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
You should use SupportMapFragment instead of MapFragment.
Change
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
to
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Change
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
TO
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(
R.id.map)).getMap();
Whatever you have done is ok with older version of GooglePlayServices, but its apparently visible from your logcat that you are using GooglePlayServices 13 or higher so you need to add the meta data tag in your manifest just the way Raghunandan have answered.

Did you compile properly the google play services in your build.gradle... you can follow the steps at the android developers site... http://developer.android.com/google/play-services/setup.html... and maybe you will have to use the gmaps api v3...

I am trying to get Google Maps Android API v2 working on Android 2.2 on a HTC Desire.
My main.xml contains the following:
<?xml version="1.0" encoding="utf-8"?>

This is my activity.

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
When I run the application, I will get the following exception. It seems that it cannot find SupportMapFragment, however, I believe that I have both the support library and Google Play Services as dependencies. When creating the project in Android Studio I chose to add support for fragments.

This is the problem that seems to be occurred when missing Google Play services.
I request you to please follow the steps mentioned below to get the Google Play services to be included in your application.
copying the google-play-services.jar in libs folder and set in the build path of eclipse is a wrong method.
import Google Play services in your project and add it in workspace.
from location of your SDK folder.
\extras\google\google_play_services\libproject\google-play-services_lib
2! Now you added Google Play Services to your work space, we have to create a reference
from our project to this library. Right-Click your project and choose “Properties” go
to the Android section, in the lower part press the “Add…” button and add a reference
to that library. Your result should be as in the screen shot bellow:
adding Google Play services library
Please Add
<permission
android:name="com.anchit.locationapi.maps.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
in your manifest

I think the Problem is how I include the GooGlePlayService... I´ve tried to add as module, as libary as External Libary but I don't know how to include and to use it right... :(

****EDIT2**
Problem solved by using this: java.lang.noclassdeffounderror: com.google.android.gms.R$styleable**
The only thing I find missing in your RecorderMap.java file is that you haven't imported the SupportFragment class. So add this line to it
import com.google.android.gms.maps.SupportMapFragment;
If that doesn't work, then check out the following.
From what you are saying, it means you have already installed the google play services. If not, then try installing it using this link http://developer.android.com/google/play-services/setup.html
After that, referencing the google play services library should be as easy as editing your build.gradle file. The current version of android studio makes this possible. Under dependencies in your build.gradle file, add the following code
compile 'com.google.android.gms:play-services:3.1.36'
You seem to have your API key intact.
Finally, remember you need to test your app on an actual android device and not an emulator. The android API version 2 is not yet able to display maps on emulators.
I think this should be okay for your app to work.
