奇怪的InputDispatcher错误“消费者关闭了输入通道或发生了一个错误。events = 0x8”

Question

我刚刚创建了一个具有两个类（Launcher和Menu）的android应用（API 7）。启动器有几行：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = new Intent(this, com.bce.tip.core.MenuActivity.class);
    startActivity(intent);
    finish();
}

菜单是活动，具有以下内容：

public class MenuActivity extends Activity {

  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.menu);  
  }

  @Override
  public void onDestroy() { 
      super.onDestroy();     
  }
}

而且我收到类似这样的错误，之前没有堆栈跟踪...

01-03 11:28:47.279: WARN/ActivityManager(164): No content provider found for:

或这个

这是我的清单：

        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar"
        android:screenOrientation="portrait">
        <intent-filter>
            <action
                android:name="android.intent.action.MAIN" />
            <category
                android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity
        android:name="com.bce.tip.core.MenuActivity"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar"
        android:launchMode="singleTask"
        android:screenOrientation="portrait">
    </activity>


</application>

任何想法如何解决这个问题？
