The bounty run out without somebody mentioning the accountManager. I just stumbled over it. Wouldn't that be a method to achieve the behaviour described by me?

推荐答案

您你的SD卡就像迈克尔·克拉默上使用的存储陈述（让用户知道你存储数据:-)）。当应用程序被移除SD卡上的数据不会被删除。

You you use storage on the SD card like Michael Cramer stated ( Let the user know you are storing data :-) ). The data on the SD card is not deleted when the app is removed.

您可以在另一方面使用存储所有可下载，而不是使用用户名使用哪个是唯一的电话的IMEI在需要时和细节的服务器。即使用户重新安装操作系统，他将仍然能够读取该设置方式。

You could on the other hand use a server which stores all the details which can be downloaded as and when required and instead of using a user name use the IMEI of the phone which is unique. That way even if the user reinstalls the OS he will still be able to refetch the settings.
