I have checked all the solutions, comments and answers of all other questions in StackOverflow.

I have been running, compiling and debugging my app for months. But suddenly it started to appear this message in my Eclipse when using my Nexus to play with it.

MOBILE:

• I have no root !!! (It‘s a Nexus, and I have no root, and all the answers in other Stackoverflow‘s questions need root to be executed)
• The application is uninstalled, there‘s no trace of it in "Applications"
• Since I don‘t have root access, I can not access to /data/data folder, or /data/local, or /data
• I do know problem would be solved resetting the phone to factory settings, but, sincerely, I can not.

ECLIPSE:

• I have cleaned the project many times, restart Eclipse and even update it
• I can not change the name of the project (as one solution suggests), since it‘s a long time project and I can not change it

• Console says:

  • Installation error: INSTALL_FAILED_UID_CHANGED
  • Please check logcat output for more details.
  • Launch canceled!

• Logcat says:

  • 01-05 12:18:19.265: W/ActivityManager(761): No content provider found for permission revoke: file:///data/local/tmp/MyApp.apk
  • 01-05 12:18:20.855: W/PackageManager(761): Package couldn‘t be installed in /data/app/com.myapp-1.apk

• I can install, uninstall other APK/applications with no problems at all. So it‘s not about permissions in /data folder/subfolders

CONSOLE:

• If I try to uninstall (with -d or any other parameter) the app it says: "Failure" (because adb does not find the app in the phone)

So, I‘m not debugging with virtual machine / emulator. I have a Nexus no-rooted with no trace of the application, and I can not build the app from Eclipse to the device.

Thank you

我已经检查了所有的解决方案，在计算器的所有其他问题的意见和答案。

我已经运行，编译和调试应用程序的几个月我。但是它突然开始出现此消息时，我使用我的Eclipse Nexus玩它。

手机

• 我没有根！！！（这是一个关系，我没有根，和其他栈溢出的问题所有的答案需要根被执行）
• 应用程序卸载，没有在“应用程序”
• 因为我没有root权限，我不能访问/数据/数据文件夹，或/数据/地方，或/数据
• I做知道问题会得到解决，重置手机出厂设置，但是，真诚，我不能。

日蚀

• 我已经打扫过多次重新启动Eclipse项目，甚至更新
• 我不能改变项目的名称（作为一个解决方案建议），因为它是一个长期项目，我无法改变它

• 控制台说：

  • 安装错误：install_failed_uid_changed
  • 请检查logcat输出更多的细节。
  • 发射被取消了！

• LogCat说：

  • TV动画12:18: 19.265：W / activitymanager（761）：不允许内容提供者发现撤销：文件：/ / /数据/地方/甲氧苄啶/ myapp.apk
  • TV动画12:18: 20.855：W / packagemanager（761）：包不能被安装在/数据/应用程序/ com.myapp-1.apk

• 我可以安装，卸载其他APK /应用程序没有在所有的问题。所以这不是关于权限的文件夹/文件/数据

控制台

• 如果我试图卸载（与D或任何其他参数）的应用程序它说：“失败”（因为亚行不在电话里找到应用程序）

所以，我不在虚拟机/仿真器调试。我有一个关系没有根本没有应用程序的痕迹，我不能从Eclipse中构建应用程序的装置。

谢谢你

This may seem odd, but my pointy-haired boss just had this issue and tried everything we could think of. Just would NOT install due to the INSTALL_FAILED_UID_CHANGED error.

He uninstalled some other apps (games) and suddenly it would install. Maybe it is an issue of disk space on internal card? Dunno, but worth a try when someone else hits it.

这可能看起来很奇怪，但我的秃头老板就有这个问题，尝试了所有我们能想到的。就不会由于错误的install_failed_uid_changed。

他被其他一些应用程序（游戏），突然它将安装。可能是磁盘空间内部卡的问题？不知，但值得一试，当别人打它。

I can solve this like below without rooting on my Nexus 5.

• Push your app to /sdcard/
• adb push test.apk /sdcard/
• adb shell
• adb shell pm install -l /sdcard/test.apk

-l option means - pm install: installs a package to the system. Options: -l: install the package with FORWARD_LOCK.

我能解决这个像下面没有生根在我的Nexus 5。

• 把你的应用程序/ sdcard /
• 亚行将test.apk / sdcard /
• 亚行壳
• 亚行壳时安装L / sdcard / test.apk

我选择指PM的安装：安装软件包系统。选项： L：安装包。

First time this happened I tried installing from eclipse, from command line etc.... Everything failed so I did a factory reset which then worked.

24 hours later it happened again.

Not wanting to do another factory reset, I tried all the same things again to no avail.

Lastly I tried downloading our current app from the appstore, which miraculously worked.

I then used adb to reinstall.

So if you have a version of your app in the app store, try installing that to get something on your phone, then do a reinstall "adb -d install -r $PACKAGE.apk

Hope this helps someone.

第一次发生这种事我试着安装Eclipse，从命令行等……一切失败，所以我做了一个工厂复位，然后工作。

24小时后，它再次发生。

不想做另一个工厂复位，我想同样的事情没有用。

最后，我试着从AppStore下载我们当前的应用程序，它奇迹般地工作。

然后我用亚行重装。

所以如果你在应用商店里有一个自己的应用程序版本，安装，试着得到的东西在您的手机，然后做一个重新安装“亚行- D - R $ package.apk安装

希望这有助于人。

Here are some other things to check/try that are safe to do:

• Make sure your package name is 100% unique and not colliding with another app. You could temporarily change it to test.
• Try powering your phone off and then back on to clear data caches.
• Try a soft reset for your device (which might be the same as powering off/on).

这里有一些其他的东西来检查一下，是安全的吗：

• 确保你的包的名称是100%个独特的和不碰撞另一个应用程序。你可以暂时改变它的测试。
• 尝试为您的手机关机然后重新明确数据高速缓存。
• 尝试为你的设备软复位（这可能是同断电/上）。

This (or some other magic) helped me:

adb shell pm clear MY_PACKAGE_NAME

这个（或其他一些魔法）帮助我：

adb shell pm clear MY_PACKAGE_NAME

This is because of if you have install the app with same package name. So try to remove that one.

这是因为如果你有安装程序相同包名。所以尝试删除一个。

I could only fix this by rooting. I know you don‘t want to do that, but it worked for me. I downloaded Titanium Backup then found my uninstalled app crossed out in the list on Titanium Backup. I couldn‘t get rid of that crossed out one until I went to Batch Actions then Remove orphan data. That allowed me to re-install my app and it worked well.

我只能通过生根解决这个。我知道你不想这样做，但它为我工作。我下载了钛备份然后发现我的卸载程序删去了钛备份列表。我无法摆脱，划掉一直到我去那批行动消除孤儿数据。让我重新安装我的应用程序和它的工作。
