当我尝试在我的Nexus 4运行4.2.1运行我的应用程序，我一直在Eclipse中收到此错误：

When I try to run my app on my Nexus 4 running 4.2.1, I kept on getting this error in eclipse:

[2012-12-22 19:30:51 - Rhiokai] Installation failed due to invalid APK file!
[2012-12-22 19:30:51 - Rhiokai] Please check logcat output for more details.
[2012-12-22 19:30:51 - Rhiokai] Launch canceled!

我累推，并通过亚行安装，但它也不能工作。我想通了，这是因为在logcat中此消息的：

I tired pushing and installing via adb but it didn't work either. I figured out that it was because of this message in Logcat:

12-22 19:37:29.326: W/zipro(7371): Unable to open zip '/data/local/tmp/Rhiokai.apk': Permission denied
12-22 19:37:29.326: D/asset(7371): failed to open Zip archive '/data/local/tmp/Rhiokai.apk'

在如何解决这个问题的任何想法？

Any ideas on how to fix this issue?

推荐答案

如果您已经有设备使用相同的包名的应用程序的签名版本，则可能需要重新安装之前卸载它（除非你要再次签字，然后上传签署应用程序的设备）。

If you already have a signed version of the application on the device with the same package name, you might need to uninstall it before re-installing it (unless you want to sign it again and then upload that signed app to the device).
