I would like to use a Google Map in my current application. Before integrate it to my app, I created a test project to understand the functionalities.
I read this : https://developers.google.com/maps/documentation/android/start#installing_the_google_maps_android_v2_api
and this :
http://developer.android.com/google/play-services/setup.html#
After a lot of problems with these errors :
didn't find class com.google.android.gms.maps.MapFragment
and
Found 2 versions of android-support-v4.jar in the dependency list,
but not all the versions are identical (check is based on SHA-1 only at this time)
When I run my project, Eclipse says "Launching Test:(99%)", then my computer temperature up to 100°C and Eclipse take 512% of my CPU ! So I'm obliged to force Eclipse to quit.
I spent a lot of time on stack overflow, rebuild, clean, add support library, delete project and recreate from the beginning etc.
Help me, I just want to create a basic app to test a GoogleMap !
My code :
MainActivity.java
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
activity_main.xml

public class YourActivity extends FragmentActivity {
GoogleMap map;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_activity);
map =((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.iqamah_map)).getMap();
}
}
your xml :
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/iqamah_map"
android:layout_width="match_parent"
android:layout_height="match_parent"

Add this in your Manifest
<uses-permission android:name="com.example.test.permission.MAPS_RECEIVE" />
<uses-library android:name="com.google.android.maps" />
Even me having the same issue, then instead of getting API key from Google Map Android V2, i took the API key from Google Maps Embed API and included in the Manifest and solved my problem.
Proof:
1.API key i took for project
2.Used Key in Manifest.xml

I have tried everything I can think of. I have made sure that I have Google Maps Android API in the google apis. I have renewed my debugging key many times, I have downloaded the google-play services and I have copied the lib jar into my directory. I have ensure that my target sdk is Google api 17, I have included all of the permissions that I could find that I might need. I've looked all over StackOverflow for help, and the above are the help that I could find, but my app still displays a blank screen and zoom buttons. I'm really at a loss for what to do now. Are there some other things I have not done correctly? How might my access my SHA1 code? I have done it through the command line and eclipse, but my logcat says that it may still be an authorization issue.
public class MapsActivity extends FragmentActivity
{
GoogleMap gm;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.maps);
gm = ((SupportMapFragment) (getSupportFragmentManager()
.findFragmentById(R.id.map))).getMap();
gm.setMapType(GoogleMap.MAP_TYPE_NORMAL);
gm.setMyLocationEnabled(true);
}
}
There are two keys.Debug and release key. Release key procedure,you can refer here.
Google Map Android API v2 can't display map in play store application
In your MainActivity you will have to load the GoogleMap. Just putting fragment in xml file doesn't going to load the map.
Try out as below:
public class MainActivity extends FragmentActivity {
private GoogleMap mMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 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) {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
}
}
}
Your manifest looks right. It's definitely a problem with your key.
In the api console, under services, make sure you have selected Google Maps Android API v2 and not Google Maps API v3. Also, make sure you have appended your package name to your key and that your are generating your SHA-1 on the same key that you are signing with. If this is debug mode, use:
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore -list -v
If release mode use your release keystore.
So it is problem with your API key, create new API key with your SHA-1 key and package name(mentioned in Android manifest.xml) separated with semi column.
See here,just change the api key with your key in manifest file and follow these steps:
and make sure that your google_play_services_lib project should be present in your project's work space only.

I want to display google maps in my android application. I tried with the google api, but it seems to have problems with API 12 and lower. So i used the example in this page (http://www.truiton.com/2013/05/android-supportmapfragment-example/), but it doesn't seem so work in my API 7 device (xperia 10 mini pro). I used the same code in that page and i get this error after the application starts:
10-18 18:04:55.481: E/AndroidRuntime(3980): Uncaught handler: thread main exiting due to uncaught exception
10-18 18:04:55.491: E/AndroidRuntime(3980): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.example.maps/com.example.maps.MainActivity}: java.lang.ClassNotFoundException: com.example.maps.MainActivity in loader dalvik.system.PathClassLoader#458fc8e0
I get this error even if i did the "Add support library" in the "Android tools" menu, but it doesn't work. I saw that using GM with a web view is not a great idea, so i wanted to fix this problem.
you need to use 2.2 (API 8) and up inorder to use google maps v2

This issue is common BUT I didn't find a solution on google, or stackoverflow (4days of research...)
Here is the thing :
I need to display a full screen google map, which i ve already done several times in other application i've developped.
BUT here i can't get it to work for an unknow reason !
The warning and the error i get when i open the SherlockFragmentActivity which contains the map :
The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
Here i'll explain how i did things in detail and post some code :
LIBRARY IMPORT :
Last version of Google play services imported in eclipse as library (checked)
In the project the google play services are imported as library in properties (like ABS)

// MAP
_googleMap = ((TransparentSupportMapFragment) getSupportFragmentManager().findFragmentById((R.id.map))).getMap();
//the map should still display at this point
}
}
And so that's it, the main code is here
The map was working up until now, i didn't do nything with the code map related...
I tried to regenerate a debug key on the google console, change the permissions .. etc i am out of idea !!!!
After changing the API key in AndroidManifest.xml you must clear application data.
To clear application data do one of the following:
Go to Settings > Application Manager > Select Your Application > Clear Data
Uninstall the application before re-installing it.
<uses-feature android:glEsVersion="131072" android:required="true" />
Put this under your permissions in your manifest.

Finally, this is what my Libraries folder in the Java Build Path tool look like:
I've been really beating my head against a wall on this one. Any help would be appreciated.
This is bit late but I had the exact same issue and could at least resolve the "java.lang.NoClassDefFoundError:". In project property->java Build path -> Libraries, I had included android-support-v4.jar from android sdk path. This lib was available during compile time but not at run time. You need to copy this jar from sdk path to application libs location that way this lib is statically added to your app and could be found during run time. hope this helps. This solution I found after lots of search in StackOverFlow. Hers is the link. Trying to use DialogFragments via v4 compatability causes NoClassDefFoundErrors
It turns out the issue had to do with a change in Android versions.
More information and the fix can be found http://www.wiseappsllc.com/homepage/android-dev-tips
I had same problem, then i resolved it by checking the build path of the project. There i had two map jars. I deleted one in libraries, Now it is working fine. Just check it may work.
