我有一个基于我大量修改的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,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某个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?
这是清单文件:

以下是关于活动的示例,在此更改之前已确认该活动有效:
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。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,那么为什么墙纸会起作用,因为服务名称的限定方式完全相同?
编辑
Dunamis 取得了出色的成绩。最初的名称是 ffvideolivewallpaper.frankandrobot.com,但从那以后它经历了几次更名。一个这样的名称是 com.nightscapecreations.orionkeysfree。看起来仍然有对我在设置 xml 文件中完全错过的那个旧名称的引用。例子:
<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。我在此文件和清单文件之间尝试了完全限定名称和简单点符号“.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
