在Android的应用程序未安装“错误 [英] 'App not Installed' Error on Android

问题描述

我有一个程序在Android模拟器的工作。现在每一次我一直在创造一个签名的apk并将其导出到我的HTC Desire测试。它具有所有被罚款。

I have a program working in the Android Emulator. Every now and again I have been creating a signed .apk and exporting it to my HTC Desire to test. It has all been fine.

在我最新的出口.apk文件时得到未安装应用程序，当我尝试安装apk文件的错误消息。它运行良好的模拟器。

On my latest exported .apk I get the error message 'App not installed' when I try to install the .apk. It runs fine on the emulators.

正如我主要是在测试上的模拟器，只有每一个现在，再出口到真正的电话，我不知道什么时候发生的。这是什么不安装在物理的手机，但在模拟器运行正常？

As I have mainly been testing on the emulators and only every now and again exporting to a real phone I am not sure when this happened. What is the likely cause of it not installing on a physical phone but running fine in the emulators?

我试图重新启动电话和放大器;删除现有.apk文件，并没有修复故障

I have tried rebooting the phone & removing the existing .apk, does not fix fault

感谢

推荐答案

我也有类似的问题，那是因为我是想在手机上安装的APK具有相同的apk的previous版本，并且都APK尚未用相同的证书签名。我的意思是，当我用同样的证书，我就能够覆盖previous安装目录，但是当我改变证书的两个版本之间的安装目录是不可能的。您是否使用了相同的证书？

I had a similar issue and it was because I was trying to install an apk on a phone with a previous version of the same apk, and both apk hadn't been signed with the same certificate. I mean when I used the same certificate I was able to overwrite the previous instalation, but when I changed of certificate between both versions the instalation was not possible. Are you using the same certificate?
