Answer 1

The logcat is saying it:

04-16 21:04:18.033: E/AndroidRuntime(18078): Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 7095000 but found 0.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

Always look fot this Caused by: in the logcat, it should show you a enough information to find and correct a problem with your app, like in this case.

    The meta-data tag in your app's AndroidManifest.xml does not have the right value.  
Expected 7095000 but found 0.  
You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

So just do what it says, put this

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

inside the <application> tag in your AndroidManifest.xml file.

UPDATE:

As I said, you shuld look for this Caused by, here it is

04-17 20:15:36.956: E/AndroidRuntime(24437): Caused by: java.lang.SecurityException: The Maps API requires the additional following permissions to be set in the AndroidManifest.xml to ensure a correct behavior:
04-17 20:15:36.956: E/AndroidRuntime(24437): <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

See this:

The Maps API requires the additional following permissions to be set in the AndroidManifest.xml to ensure a correct behavior:<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

And now just add that permission to your AndroidManifest:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Answer 2

Change in your Fragment tag, from

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

to

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

If this does not solve, then

Add meta-data within application element: Logcat clearly shows the error.

04-16 21:04:18.033: E/AndroidRuntime(18078): Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 7095000 but found 0.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

Like This:

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
            ...

Answer 3

Append <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> in your manifest file's <application> element.
