MapActivity with StrictMode çalışmıyor - Yardım

Question

Android geliştiricisinin blogunda Tim Bray's post "New Gingerbread API: StrictMode" okuduktan sonra, projemde kullanmaya karar verdim. Performans sorunlarının, sorun olmadan önce yakalanmasına yardımcı olmayı umuyorum.

Sorunum, MapActivity özelliğini her yüklediğimde, uygulamanın kaldığı, ancak yalnızca StrictMode etkin olduğunda karşılaştığım. Basit, kod aktivitesi olmadan bile ölür.

Herkes, StrictMode'u MapActivity ile başarıyla kullandı mı? Eğer öyleyse, hile nedir?

LogCat çıktısı şu şekildedir:

TestActivity - onCreate 
TestActivity - onStart 
TestActivity - onResume

Etkinlik kod şudur: (Ben ekstra şeyler var biliyorum ama standart yöntemler yürütme yaptıklarını görmek istedim)

public class TestActivity extends MapActivity { 

    private final static String TAG = "TestActivity"; 

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

     Log.d(TAG, "TestActivity - onCreate"); 
    } 

    @Override 
    protected void onStart() { 
     // TODO Auto-generated method stub 
     super.onStart(); 

     Log.d(TAG, "TestActivity - onStart"); 
    } 

    @Override 
    protected void onResume() { 
     // TODO Auto-generated method stub 
     super.onResume(); 

     Log.d(TAG, "TestActivity - onResume"); 
    } 

    @Override 
    protected void onPause() { 
     // TODO Auto-generated method stub 
     super.onPause(); 

     Log.d(TAG, "TestActivity - onPause"); 
    } 

    @Override 
    protected void onStop() { 
     // TODO Auto-generated method stub 
     super.onStop(); 

     Log.d(TAG, "TestActivity - onStop"); 
    } 

    @Override 
    protected void onRestart() { 
     // TODO Auto-generated method stub 
     super.onRestart(); 

     Log.d(TAG, "TestActivity - onRestart"); 
    } 

    @Override 
    protected void onDestroy() { 
     // TODO Auto-generated method stub 
     super.onDestroy(); 

     Log.d(TAG, "TestActivity - onDestroy"); 
    } 

    @Override 
    protected boolean isRouteDisplayed() { 
     // TODO Auto-generated method stub 

     Log.d(TAG, "TestActivity - isRouteDisplayed"); 

     return false; 
    } 

} 

düzen :

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <com.google.android.maps.MapView 
     android:id="@+id/campusMap" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:clickable="true" 
     android:apiKey="<key>" /> 

</LinearLayout>

Sorun yok, AFAIK. MapView ve MapActivity, 2008'de ya da daha sonra yazılmıştır ve bundan sonra, anlatabildiğim kadarıyla önemli ölçüde değiştirilmemişlerdir. Ana uygulama iş parçacığı üzerinde G/Ç gibi bazı kötü uygulamalar var şaşırmayın.
