Answer 1

Aynı hataları var. Bu bana yardımcı oldu. v.4 kütüphanesini kontrol etmeye çalışın. Seç proje ve gidin: Properties-> Java Path-> Sipariş ve İhracat

Düzenlendi kurmak android.support.v4 kütüphane içinde işaretli olduğundan emin olun, Properties-> Java kurmak Path-> Sipariş ve İhracat Listede değilse işaretleyin. Temiz projeyi (i zaten proje kütüphane ithal varsayıyorum) ve

Answer 2

değişiklik

.GcmBroadcastReceiver 

için

com.example.smsmining.GcmBroadcastReceiver 

ve

.GCMIntentService 

için

çalışması gerekir

com.example.smsmining.GCMIntentService 

Bundan sonra, temiz bir proje. Bu benim için çalışıyor.
