I’m looking for something like the Keychain on the iPhone, but for Android development.

I’m looking for something like the Keychain on the iPhone, but for Android development. Something that gives me the capability to save small key-value pairs that are persistent and unchanged even if the user reinstalls the application.

Is there something like that? Can I use the standard preferences that way?

I would like to achieve a behavior similar to the way it works with games on a PC – writing the save files to another folder so that after deletion and reinstallation the save files are not lost.

Edit:

The bounty ran out without somebody mentioning the accountManager. I just stumbled over it. Would that be a method to achieve the behaviour described by me?

    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.

    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.

    for getting the IMEI you may refer : How to get the device's IMEI/ESN programmatically in android?
