को

मैं एक वर्ग डाली अपवाद हो रही है ढाला नहीं जा सकता अर्थात्java.lang.ClassCastException: android.app.Application greendroid.app.GDApplication

java.lang.ClassCastException: android.app.Application cannot be cast to greendroid.app.GDApplication

जब मैं हरे रंग का उपयोग करने के कोशिश कर रहा हूँ मेरी परियोजना में droid पुस्तकालय। यहां संबंधित कोड है। मैं यह पता लगाने की कोशिश कर रहा हूं कि क्या गलत हो रहा है लेकिन अभी भी कोई भाग्य नहीं है। किसी भी तरह की मदद की सराहना की जाएगी। धन्यवाद।

public class MainMenu extends GDActivity{ 
    private QuickActionWidget mBar; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setActionBarContentView(R.layout.mainmenu); 
     mBar = new QuickActionBar(this); 
     mBar.addQuickAction(new QuickAction(this, R.drawable.food, "food")); 

Button foodButton=(Button)findViewById(R.id.food); 




foodButton.setOnClickListener(new View.OnClickListener() { 

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
    mBar.show(v); 

} 
}); 


} 

    }

यहाँ मेरी mainmenu.xml

अपना लॉगकैट डालें और mainmenu.xml –

मैं केवल अनुमान लगा सकता हूं। क्या आप एंड्रॉइड ऐप extends GDApplication है?

उदाहरण के लिए (AndroidManifest.xml में):

<application 
     android:icon="@drawable/ic_gdcatalog" 
     android:label="@string/app_name" 
     android:theme="@style/Theme.GDCatalog" 
     android:name=".CatalogApplication"> 
... 
...

आप अपने वर्ग में करना चाहिए:

public class CatalogApplication extends GDApplication { 

    @Override 
    public Class<?> getHomeActivityClass() { 
     return CatalogActivity.class; 
    } 

    @Override 
    public Intent getMainApplicationIntent() { 
     return new Intent(Intent.ACTION_VIEW, Uri.parse(getString(R.string.app_url))); 
    } 

}

तुम भी GDCatalog sample Application डाउनलोड करने और ग्रहण में चला सकते हैं।

हाँ @ r.piesnikowski जोड़ें जो मेरी समस्या थी। मैंने कैटलॉग आवेदन की घोषणा नहीं की। –

यह सिर्फ मुझे सहेजा गया, एक पुराने ऐप को पुनर्गठित किया और 'एंड्रॉइड: नाम = "" मुख्यधारा के भीतर "भूल गया! – wired00

java.lang.ClassCastException: android.app.Application greendroid.app.GDApplication
