開始活動的Android錯誤

我正試圖從另一個活動開始活動，並收到錯誤並且應用程序強制關閉。這裏是logcat的：開始活動的Android錯誤

10-07 11:29:04.002: D/SntpClient(61): request time failed: java.net.SocketException: Address family not supported by protocol

在這裏，這是我的代碼，我怎麼稱呼活動：

Intent intent=new Intent(Boicemain.this,draw.class); 
      startActivity(intent);

這是我的活動我打電話：

public class draw extends Activity { 
drawview drawView; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    // Set full screen view 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
            WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 

    drawView = new drawview(this); 
    setContentView(drawView); 
    drawView.requestFocus(); 
} 
}

你錯過了實際的異常（logcat stacktrace的第一行）... – nneonneo

你需要爲我們提供'Boicemain.onPause（）'和'Boicemain.onDestroy（）'方法的源代碼 – HitOdessit

i haven' t實現onPause或onDestroy方法！ –

因爲你沒有把最重要的錯誤放在該日誌上，我想你沒有在你的AndroidManifest.xml中定義你的活動。爲了更好地檢查你的錯誤，請把所有的錯誤日誌從頂部開始
