我看到这个错误，你在AndroidManifest中声明了这个活动，但我无法做到。

public boolean onOptionsItemSelected(MenuItem item) { 
     switch(item.getItemId()){ 
     case R.id.Mapy: 

      Intent intent = new Intent(this,Map.class); 
      startActivity(intent); 


      break; 
     default: 
      return super.onOptionsItemSelected(item); 
     } 
     return true; 
    } 

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

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="17" />

    <application 

     android:allowBackup="true"

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

public class Map extends MapActivity { 

    private MapView mapView; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.mapactivity); 

     mapView = (MapView) findViewById(R.id.mapview); 

     mapView.setBuiltInZoomControls(true); 
     mapView.setTraffic(false); 
     mapView.setSatellite(true); 
     mapView.setStreetView(true); 


    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    @Override 
    protected boolean isRouteDisplayed() { 
     // TODO Auto-generated method stub 
     return false; 
    } 

}

好像你忘了申报活动：

pl.pawelfrydrych.flyingball.Map 

在AndroidManifest.xml中

---

到的Manifest.xml添加类似的东西其他activity标签如下：

<activity 
     android:name="pl.pawelfrydrych.flyingball.MainActivity" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    <!-- add this here: --> 
    <activity 
     android:name="pl.pawelfrydrych.flyingball.Map" 
     android:label="@string/map_title" > 
    </activity>
