android数独游戏,按钮按下崩溃游戏

Question

我正在创建一个数独游戏,但是当我按下按钮时它会崩溃游戏.这是我的代码:

FPSudoku.java:

package org.example.fpsudoku;

import android.app.Activity; import
android.os.Bundle; import
android.content.Intent; import
android.view.View; import
android.view.View.OnClickListener;

public class FPSudoku extends Activity
implements OnClickListener{
     @Override    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);

      View newButton = findViewById(R.id.new_game_button);
      newButton.setOnClickListener(this);
      View aboutButton = findViewById(R.id.how_to_play_button);
      aboutButton.setOnClickListener(this);
      View exitButton = findViewById(R.id.exit_game_button);
      exitButton.setOnClickListener(this);
          }

      public void onClick(View v) {
          switch (v.getId()) {
          case R.id.how_to_play_button:
          Intent i = new Intent(this, Howtoplay.class);
          startActivity(i);
          break;

      } 
  }
}

Howtoplay.java

package org.example.fpsudoku;

import android.app.Activity; import
android.os.Bundle;

public class Howtoplay extends
Activity {  @Override   protected void
onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.howtoplay);
    }

}

更新

android manifest.xml

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".FPSudoku"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <activity android:name=".Howtoplay"
                  android:label="@string/how_to_play_title" >
                </activity>
                </activity>

</application>

更新了logcat

隐藏在您的LogCat中是您的问题的答案:

ActivityNotFoundException: Unable to find explicit activity class {org.example.fpsudoku/org.example.fpsudoku.Howtoplay}; have you declared this activity in your AndroidManifest.xml?
