There are two things wrong with the manifest:

<activity android:name=".Map"></activity> 

should be outside the other activity and in application.

<uses-library android:name="com.google.android.maps" />

should be inside application

Use this xml:

  <?xml version="1.0" encoding="utf-8"?>
  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.clubber"
  android:versionCode="1"
  android:versionName="1.0">

<application android:icon="@drawable/icon" android:label="@string/app_name">

    <uses-library android:name="com.google.android.maps" />     
    <activity android:name=".clubbera" android:label="@string/app_name">


        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".Map"> </activity>

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

You are missing the Map activity in your manifest. The stacktrace in logcat is probably telling you that is the error...

pls ensure your Logcat, that you had yield, Activity Not Found Exception, this is because you had forgot to register your map activity in Android manifest file.

you have to add the Activity as shown below

    <activity android:name=".clubber" android:label="@string/app_name">


        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".Map"></activity>

</application>

In order to have this running you need to put in the manifest file the following line:

<uses-library android:name="com.google.android.maps" />

but please pay attention and add the line inside the <application> tag like bellow:

<application>
    ...
    <uses-library android:name="com.google.android.maps" />
</application>
