我试图安装应用程序，我做我的手机上。但我不断收到错误

 安装错误：INSTALL_PARSE_FAILED_NO_CERTIFICATES
 

我使用的Eclipse。我以前从来没有看到这个问题。我有我的手机上几百次运行我的应用程序。在我的项目中的任何文件不存在明显的错误。我编辑的清单文件加大了版本，但它没有工作。我打扫我的项目。我卸载了我的应用程序的当前版本，从我的手机。但这一切的工作。

我完全不知道是什么问题。在LogCat中声称，它是我的main.xml文件有问题。

  ERROR / PackageParser（956）：##包我的包名没有证件入境RES /布局/ main.xml中;无视！
 

我还没有，所以我不知道，可能是什么问题接触过这个文件。

更新：事情变得更加混乱。在问题发生我将丁基下降了几个PNG文件到绘制文件夹（其中已经有几个）。之后拉我的头发，我明白了这个问题可能是这些文件。我（共5）删除了所有这些，它现在的作品。唯一的问题是我不知道为什么他们搞砸了安装。

这似乎是一个相当普遍的问题：http://$c$c.google.com/p/android/issues/detail?id=830

一个解决方法是导出签名的软件包和signapk.jar手动签署

评论26 lucasiturbide，04月14日，   2010大家好。我已经解决了这个   在我的项目通过签署APK与   在debugkey和jarsigner工具   通过Android的工具提供的。

只需执行这样的：

 的jarsigner -verbose -keystore＆LT; USERHOME＆GT; /安卓/ debug.keystore＆LT; package.apk＆GT; androiddebugkey
 

和你将有你好看清新   工作APK仅用于调试   目的。记住，你必须签署   你的APK具有有效签名   在市场发布应用程序

对于调试键与别名androiddebugkey密码为机器人。

I'm trying to install the app I making on my phone. But I keep getting an error

Installation error: INSTALL_PARSE_FAILED_NO_CERTIFICATES

I'm using Eclipse. I've never seen this problem before. I have run my app on my phone hundreds of times. No apparent errors exist in any files of my project. I edited the Manifest file upping the version, but it didnt work. I cleaned my project. I uninstalled the current version of my app from my phone. But none of this works.

I have absolutely no idea what the problem is. The LogCat claims it is a problem with my main.xml file.

ERROR/PackageParser(956): Package ##MY PACKAGE NAME has no certificates at entry res/layout/main.xml; ignoring!

I havent touched this file so I dont know what could be the problem.

UPDATE: Things got more confusing. Before the problem occured I drag-n-dropped a few png files into the drawable folder (where there are already a few). After pulling my hair out it dawned on me the problem might be these files. I deleted them all (5 in total) and it works now. Only problem is I dont know why they screwed up installation.

It seems to be a fairly common issue: http://code.google.com/p/android/issues/detail?id=830

A workaround is to export an unsigned package and sign it manually with signapk.jar

Verbatim:

Comment 26 by lucasiturbide, Apr 14, 2010 Hi everybody. I have solved this in my project by signing the APK with the debugkey and the jarsigner tool provided by android tools.

Just execute this:

 jarsigner -verbose -keystore <userhome>/.android/debug.keystore <package.apk> androiddebugkey

and you will have your nice fresh and working apk for debugging only purpose. Remember you have to sign your APK with a valid signature to publish your application at the Market

The password for the debug key with the alias "androiddebugkey" is "android".
