Answer 1

As you had mentioned in your code, You have only one Activity called HelloGoogleMaps and in your AndroidManifest you have declared two activities!! your HelloGoogleMapsActivity is useless. You are getting the error because you set HelloGoogleMapsActivity as the Launcher activity and this activity don’t even exist!!

Solution:
change your AndroidManifest.xml like that and you will get your app work if you had managed to get the apikey for your map correctly:

<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar"
        android:name=".HelloGoogleMaps" >
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>        
    </activity>
    <uses-library android:name="com.google.android.maps"/>
</application>
