achievementDatabase.open();
//achievementDatabase.resetDatabase();
achievements = achievementDatabase.getAllAchievements();

}
}
}
}
成就更新服务：
package whiskeymedia.com;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import whiskeymedia.com.vo.Achievement;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
public class AchievementUpdateService extends Service{
private AchievementDatabase achievementDatabase;
private final IBinder mBinder = new MyBinder();
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
HtmlParser htmlParser = new HtmlParser();
try {
List<Achievement> achievements= htmlParser.parseDocument();
achievementDatabase.loadAchievements(achievements);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return Service.START_NOT_STICKY;
}
@Override
public IBinder onBind(Intent arg0) {
return mBinder;
}
public class MyBinder extends Binder {
AchievementUpdateService getService() {
return AchievementUpdateService.this;
}
}
}
知道我做错了什么吗？
解决方法:
崩溃是因为你要回来的活页夹是BinderProxy的一个实例,而不是你当地的活页夹类.这通常是因为您的活动试图绑定到不在同一进程中的服务.跨进程边界绑定时,使用BinderProxy的实例而不是实际实例(因为它在不同的进程中).
你的AndroidManifest.xml是什么样的？
