我是按照android studio精简离线打包操作的 但是现在应用打不开了

我是按照文档http://ask.dcloud.net.cn/article/924 一步步操作的 现在集成完毕后，android studio shift+f10运行 出现Unable to start activity ComponentInfo{com.example.sunshine.hbuilderdemo/io.dcloud.PandoraEntry}: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.sunshine.hbuilderdemo/io.dcloud.PandoraEntryActivity}; have you declared this activity in your AndroidManifest.xml?
的错误。求解决！
