現在、アクティビティは破棄されていますが、ステータス アイコンはステータス バーに表示されたままです。アプリを閉じると同時にアイコンを削除するのを手伝ってもらえますか?
onDestroy セクションの問題が疑われます... LogCat 情報は、 notificationManager.cancel(NOTIF_ID);行で nullpointer 例外が発生したことです。
private static final int NOTIF_ID = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_jajko);
text = (TextView) findViewById(R.id.tvTime);
play = (Button) findViewById(R.id.butStart);
miekko = (Button) findViewById(R.id.butMiekko);
srednio = (Button) findViewById(R.id.butSrednio);
twardo = (Button) findViewById(R.id.butTwardo);
miekko.setOnClickListener(this);
srednio.setOnClickListener(this);
twardo.setOnClickListener(this);
play.setOnClickListener(this);

result_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
