Answer 1

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

этого Ассоль решить класс не найден исключение.

Answer 2

Если ваш проект содержит несколько пакетов, попробуйте вставить имя пакета в свой файл манифеста Android как;

<activity 
     android:name="com.PackageName.M1MapAppActivity" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

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