Android - Google Maps API v2 - SupportMapFragment Errors

Question

I am trying to get one of my apps back up and running with the Google Maps API v2 for the first time. I created a key for my app in my keystore, extracted the SHA1 hash, acquired an API key, then did the following in-app... I included:

google-play-services.jar

as well as importing the GooglePlayServices libraryand adding it as a reference to the project. In my Java code I simply just load the layout resource.

public class Times extends Activity{
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);
    }
}

In the layout (res/layout/map.xml) that I am trying to instantiate I have:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

I also have the following declared in my manifest:

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="tinyTech.us.ua.busschedule.permission.MAPS_RECEIVE" />

<permission
    android:name="tinyTech.us.ua.busschedule.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

And declared in the Application tag of the manifest:

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="My_API_Key" />

When the activity is loaded, it crashes with the following errors in LogCat:

FATAL EXCEPTION: main
java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable
    at com.google.android.gms.maps.GoogleMapOptions.createFromAttributes(Unknown Source)

I have attempted to research the problem, however I have been unable to find what I am looking for. Any and all help is greatly appreciated.

Answer 1

I think i had the same problem it seems that newer versions you have to add this line at the manifest

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

Answer 2

You need to extend FragmentActivity if you are using SupportMapFragment. If you are using the MapFragment you can extend Activity.

Answer 3

In your layout, use

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/map"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              class="com.google.android.gms.maps.SupportMapFragment"/>

instead of

...    
android:name="com.google.android.gms.maps.SupportMapFragment"
...

Answer 4

You must do this:

public class MainActivity extends android.support.v4.app.FragmentActivity{

}

Answer 5

This worked for me: https://stackoverflow.com/a/13744765/1215098

Seems like you have to add Google Play services as module, not just as .jar
