你使用調試器？您可以將eclipse調試器附加到電話進程。此外，logcat很可能會爲您提供堆棧跟蹤。請嘗試自己做腿部工作，而不是在這裏發佈你的代碼。 – Femaref 2013-03-09 09:41:24

發佈一些日誌來分析？ – QAMAR 2013-03-09 09:43:17

請發佈logcat – 2013-03-09 11:09:30

如果您只使用BroadcastReceiver然後不寫Bttest11在活動bcoz那不是活動。

和如果您想要活動，則創建一個活動類並從那裏調用接收器。定義了Android清單中的活動。在活動標籤和接收器標籤的接收器寫入

public class MainActivity extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    startService(new Intent(MainActivity.this, MyService.class)); 
}

}
