Bir RSS Haber Okuyucu uygulaması yapmaya çalışıyorum ve bir RSS yayın listesine yeni web siteleri eklemek için iş parçacıkları kullanmak için AsyncTask kullanıyorum. Ancak ne zaman yeni URL’ye koyup 'ADD' ye bastığımda, uygulama çöküyor. LogCat diyor -Yakalanmamış istisna ile çıkma iş parçacığı, AyncTask # 2 Önemli Hata
12 ThreadId: Konu yakalanmamış istisna ile çıkarken", "AsyncTask 2. FATAL İSTİSNA" ve java.lang.RuntimeException: Hata doInBackground yürütülürken()
yardım edin! (I ADT kullanıyorum PS.)

Sorunuzu biraz denemek ve temizlemek mümkün mü? (Günlükleri ve çıktıları yayınlamanız iyidir, ancak biçimlendirme sorununuzu okumak ve anlamak için oldukça zor hale getirir.) –
