Is there any method to upgrade apk in android? 在android中有没有升级apk的方法？

3 个解决方案

Once you've downloaded the APK, Android itself decides if the program is installed and needs to be upgraded, or if it is a new installation. 下载完APK后，Android会自行决定是否已安装该程序并需要升级，或者是否为新安装。 Users can decide for themselves whether to upgrade or not. 用户可以自行决定是否升级。

Besides how to find out when there is an update available, it's not possible to upgrade it without prompting the user with the "Do you want to install". 除了如何找出有可用更新的时候，如果没有提示用户“你想安装”，也无法升级它。 Android doesn't allow third apps to install apps unless the phone is rooted and your app has root access, but I think that this isn't your target group. Android不允许第三个应用安装应用，除非手机已植根并且您的应用具有超级用户权限，但我认为这不是您的目标群体。

I have no experience with that but what you could try is loading classes manually from your server and then store it in the assets folder. 我没有这方面的经验，但您可以尝试从服务器手动加载类，然后将其存储在assets文件夹中。 http://android-developers.blogspot.com/2011/07/custom-class-loading-in-dalvik.html http://android-developers.blogspot.com/2011/07/custom-class-loading-in-dalvik.html

This is one approach, I don't think that it's very handy and easy but it would work. 这是一种方法，我不认为它非常方便，但它会起作用。

Hope it helps! 希望能帮助到你！

PS: And just because I'm wondering, is there a reason why don't you wanna publish it on the Android Market? PS： 只是因为我想知道，为什么你不想在Android Market上发布它？

When you are publishing an App on your private web server, you need to create a process through which you can check for new version .There is No in built method for doing this . 当您在私人Web服务器上发布应用程序时，您需要创建一个过程来检查新版本。 在构建方法中没有这样做。

I have created one as well. 我也创造了一个。
