java - 无法解决android中的错误？

Question

我正在开发安卓问答游戏。 QuestionActivity 和 EndgameActivity 是我游戏中的两个类。我希望当我的游戏结束时控制权转移到 EndgameActivity。为此，我在 QuestionActivty 类中添加了

Intent i = new Intent(this, EndgameActivity.class);
            startActivity(i);
            finish();

在 if(currentGame.isGameOver()) 方法中。但是在回答了最后一个问题之后，当我的游戏结束控制没有转移到 EndgameActivity 并且日志猫显示以下错误时。

QuestionActivity 类-

public class QuestionActivity extends Activity implements OnClickListener{

    private Question currentQ;
    private GamePlay currentGame;
    private CountDownTimer counterTimer;

         }

我认为可能是定时器方法中的一些错误导致了这些错误。有人知道如何解决这个错误吗？

Answer 1

Check your manifest file you register activity
android.content.ActivityNotFoundException: No Activity found to handle Intent {     act=EndgameActivity }
