安卓重命名:找不到显式活动类

我有一个基于我大量修改的一些开源代码的动态壁纸。作为最后一项，我在 Eclipse 中右键单击它以更改包名称，世界一切都很好。墙纸工作正常。设置菜单工作正常。但是当我尝试单击设置菜单中的项目以启动另一个活动时，我得到：

 10-10 16:16:56.215: E/AndroidRuntime(13825): FATAL EXCEPTION: main
 10-10 16:16:56.215: E/AndroidRuntime(13825): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.nightscapecreations.orionkeysfree/ffvideolivewallpaper.frankandrobot.com.extLinkNC}; have you declared this activity in your AndroidManifest.xml?

以下是清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

            <intent-filter>
                <action android:name="android.service.wallpaper.WallpaperService" />
            </intent-filter>
            <meta-data
                android:name="android.service.wallpaper"

        </service>
        <activity

        <activity

            android:exported="true"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="ffvideolivewallpaper.frankandrobot.com.About"
            android:exported="true"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="ffvideolivewallpaper.frankandrobot.com.License"
            android:exported="true"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="ffvideolivewallpaper.frankandrobot.com.SelectVideo"
            android:exported="true"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="ffvideolivewallpaper.frankandrobot.com.extLinkNC"
            android:exported="true"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="ffvideolivewallpaper.frankandrobot.com.extLinkZazzle"
            android:exported="true"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="ffvideolivewallpaper.frankandrobot.com.extLinkFacebook"
            android:exported="true"
            android:label="@string/app_name" >
        </activity>
        <activity
            android:name="ffvideolivewallpaper.frankandrobot.com.extLinkGooglePlus"
            android:exported="true"
            android:label="@string/app_name" >
        </activity>
    </application>
</manifest>

下面是"关于"活动，作为示例，该活动在此更改之前已确认有效：

package ffvideolivewallpaper.frankandrobot.com;
import android.app.Activity;
import android.os.Bundle;
import android.text.method.LinkMovementMethod;
import android.widget.TextView;
import android.content.Intent;
import android.view.View;
import com.nightscapecreations.anim1.R;
public class About extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.about);
        TextView t = (TextView) findViewById(R.id.about_box);
        t.setMovementMethod(LinkMovementMethod.getInstance());
    }
    public void showLicense(View view) {
    startActivity(new Intent(About.this, License.class));
    }
}

ffvideolivewallpaper.frankandrobot.com 是旧的包名称。 Eclipse 在包名称更改期间为所有活动的 android：name 添加了前缀。我不明白的是，如果这是不正确的，那么为什么墙纸可以工作，因为服务名称以完全相同的方式限定？

编辑

杜纳米斯做出了一个很好的收获。原名是ffvideolivewallpaper.frankandrobot.com，但从那时起它经历了几次名称更改。其中一个名字是com.nightscapecreations.orionkeysfree。看起来仍然有对那个旧名称的引用，我在设置 xml 文件中完全错过了。例：

<PreferenceCategory android:title="Links and Information" >
        <PreferenceScreen android:title="Visit Nightscape Creations"
            android:summary="See more live wallpapers, get free static wallpapers, and learn about NC by visiting us online." >
            <intent
                android:targetClass="ffvideolivewallpaper.frankandrobot.com.extLinkNC"
                android:targetPackage="com.nightscapecreations.orionkeysfree" />
        </PreferenceScreen>

但是，这仍然不起作用。我尝试了此文件和清单文件之间的完全限定名称和简单点表示法".extLinkFacebook"的所有组合，但没有成功。这是我现在收到的错误，两个名称都是完全限定的：

10-11 08:19:43.176: E/AndroidRuntime(25204): FATAL EXCEPTION: main
10-11 08:19:43.176: E/AndroidRuntime(25204): android.content.ActivityNotFoundException: Unable to find explicit activity class {ffvideolivewallpaper.frankandrobot.com/ffvideolivewallpaper.frankandrobot.com.extLinkFacebook}; have you declared this activity in your AndroidManifest.xml?

以下是供参考的设置文件：

添加赏金后不久，我找到了解决此问题的方法。不过，我仍然不确定最初的问题是什么。

为了解决这个问题，我重命名了包含所有代码的 ffvideolivewallpaper.frankandrobot.com 包，以匹配清单的代码。我一直犹豫要不要这样做，因为它需要更新 video.c 文件才能将本机调用中的所有"ffvideolivewallpaper_frankandrobot_com"引用更改为"com_nightscapecreations_anim1"，并且上次我尝试过时，我把应用程序灌得很糟糕，我不得不返回备份副本。但是，在今天这样做之后，然后通过应用程序搜索/替换以查找所有其他参考资料，我能够让它工作。

不过，我仍然想知道上述问题的答案。如果我可以只保留主包名称而不是为搜索/替换而烦恼，那么将来在此基础上创建新应用程序会容易得多。但是，如果没有人知道，我将把这个标记为答案。
