"Tag <Activity>属性名称包含无效字符''."Android Manifest

Question

我在Android Manifest中收到错误"Tag属性名称有无效字符'.",而没有明显无效的字符.这是代码:

<activity
        android:name="Quiz 31"
        android:configChanges="orientation|keyboardHidden"
        android:label="Quiz 31"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar" >
        <intent-filter>
            <action android:name="com.SoulSlayerAbad.AMQ.QUIZ31" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

如您所见,代码中没有''字符.有谁知道为什么会这样？需要注意的一点是,我使用Eclipse控制台内部运行的几行Java生成了这段代码.代码是:

        int Begin = 0, End = 0; 
    Scanner sc = new Scanner(System.in);

    String Text = " <activity "+
            "android:name=\"Quiz "+Begin+"\" "+
            "android:configChanges=\"orientation|keyboardHidden\" "+
            "android:label=\"Quiz "+Begin+"\" "+
            "android:screenOrientation=\"portrait\" "+
            "android:theme=\"@android:style/Theme.NoTitleBar\" > "+
            "<intent-filter> "+
                "<action android:name=\"com.SoulSlayerAbad.AMQ.QUIZ"+Begin+"\" /> "+

                "<category android:name=\"android.intent.category.DEFAULT\" /> "+
            "</intent-filter> "+
        "</activity> ";

    System.out.println("Begining:");
    Begin = sc.nextInt();
    System.out.println("End At:");
    End = sc.nextInt();
    while(Begin <= End){
        System.out.println(Text);
        Begin++;
    }

Answer 1

android:name应该引用代表活动的类路径.它不得包含任何特殊字符或空格.

例如:

android:name="com.json.test.MainActivity"

这里MainActivity是扩展的类文件Activity.
