This is not a programming question but I feel SO is the right place to put it in.
有在市场上的Android应用程序。我们的工作是升级的应用程序在一个巨大的方式。有如此多的改变的地步，我们决定从头开始一个新的项目。
There is an android app in the market. Our job is to upgrade the app in a huge way. There is so much to change to the point where we decided to start a new project from scratch.
我的问题是：为了能够取代（升级）在Play商店中的现有应用下，我们应该怎么做？保持相同的包叫什么名字？或符号键就足够了？或两者？还是什么？
My question is: in order to be able to replace (upgrade) the existing app in the Play store, What should we do? Keep the same package name? or the sign key is enough? or both? or what?

推荐答案
您必须拥有相同的包名称和相同的签名密钥。另外，如果有任何形式的意图的/，可以从其他应用程序发起的行动，你可能要保持这些相同（以防用户设置了一个快捷方式到它们）。
You must have both the same package name and the same signature key. Also, if it has any sort of intents/actions that can be launched from other applications, you may want to keep those the same (in case a user has setup a shortcut to them).
包名称是怎样的Play商店从另一个决定一个应用程序。他们必须为每个应用程序的唯一。你不能改变它，你已经上传了，如果你想升级现有的应用程序原件后。
Package name is how the Play Store determines one app from another. They have to be unique for each app. You can't change it after you've uploaded the original if you're wanting to upgrade the existing app.
签名密钥与Play商店如何验证你是原开发商。如果你丢失或更改此键您绝对无法更新原来的应用程序！
The signing key is how the Play Store verifies that you are the original developer. If you ever lose or change this key you will absolutely not be able to update the original application!
