我modyfing我的Andr​​oid应用程序，而我在实际设备尝试它（运行应用程序在Eclipse）和所有正在不错。所以，当我已经很满意了我的变化，我为了修改版本释放它开了清单，但没有在清单的任何更改发生错误的行：

I was modyfing my android app, and I was trying it on real device (Run Application in eclipse) and all was working good. So When I was satisfied of my changes, I opened the Manifest in order to modify the version for releasing it, but WITHOUT ANY CHANGES in Manifest an error occurred at line:

<uses-permission android:name="android.permission.INSTALL_PACKAGES" />

该错误是：

Permission is only granted to system apps

这怎么可能呢？我用这条线建造我的应用程序很多次了。

How is this possible? I builded my application many times using this line.

推荐答案
