无法使用我的preferences.xml文件

Question

好的，首先，我知道有很多答案，我已经尝试了很多。我的SettingsActivity菜单有一个偏好，当我点击它时，我希望它打开另一个Activity。它每次都会崩溃。这只是我尝试过的一个例子：

XML

<Preference
            android:title="@string/open_menu_customizer" >
            <intent
                android:action="android.intent.action.VIEW"
                android:targetClass="CustomMenuActivity"
                android:targetPackage="com.triunedev.foodeze" />
        </Preference>

清单

<activity
            android:name=".CustomMenuActivity"
            android:label="@string/custom_menu_activity">
            <intent-filter>
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

这应该不是那么困难，但我是Android的新手。提前谢谢。

添加了信息。我希望这就是你的意思。

I/Process: Sending signal. PID: 7264 SIG: 9
Application terminated.

在尝试了几个不同的事情之后，我意识到我也不能用Java来调用这个活动;

public void openSettingsMenu(View view) {

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

    }

我得到了上面发布的相同错误。如果有人请求帮助。我会很感激！谢谢！

更新： 问题是：我试图用其余变量启动以下行，

SharedPreferences config = PreferenceManager.getDefaultSharedPreferences(this);

首先声明变量，然后在onCreate方法中初始化它，一切正常

<Preference
            android:title="@string/open_menu_customizer" >
            <intent
                android:action="android.intent.action.VIEW"
                android:targetPackage="com.triunedev.foodeze"
                android:targetClass="com.triunedev.foodeze.CustomMenuActivity"/>
        </Preference> 

并且清单中没有添加intent-filter。
