问题描述
我是否需要使用不同的证书签名不同的应用程序，如果他们都是一样的谷歌播放帐户下发表或我可以使用始终是相同的？如果没有特殊要求，什么是最好的做法是什么？
Do I need to use different certificates to sign different apps if they are all published under the same Google Play account or can I use always the same? If there is no particular requirement, what is the best practice?
推荐答案
您不需要发布在同一Developper户头的所有应用程序使用同一证书，并且可以使用每个应用程序一个证书。
You don't need to publish all your applications on the same Developper Accout with the same certificate, and can use one certificate per application.
但是，你必须使用发布它已先行公布使用同一证书的应用程序的更新。这意味着你应该确保你的密钥库保存在severall到位。
But you must publish updates of an application using the same certificate it has first been published with. This mean that you should make sure that your keystore is saved in severall place.
最好的做法是使用相同的证书可以在同一个进程中运行让每个developper账户单密钥库，为应用程序，并在一个安全的方式共享数据（按照Documentation).
The best practice is to have a single keystore per developper account, as application using the same certificate can run in the same process, and share data in a secured way (as per the Documentation).
