Android Question Save and share a value with other Activities

[Matteo Granatiero]

I have an app that for the first time that is started, asks us what sex we are. That said I would save forever this value (male or female) and then pass it to the Activity 2 that according to the value (male or female) shows me a certain content or with
(If value ="male"then
button1.visible = true
else
button2.visible = true
end if)
So how do I save this string value in the app forever?

Define a ProcessGlobal variable and save it in a file.
You can access this variable from any module.
When you restart the program, check if the fiele does exist.
If yes, read it it and set the variable.
If no, ask the question.

There are many ways to do this.

You can also create a variable in Process_Globals of Starter Service and store the value.

"The Starter service should be the default location for all the public process global variables. SQL objects, data read from files and bitmaps used by multiple activities should all be initialized in the Service_Create sub of the Starter service."

That said I would save forever this value (male or female)

Use a KeyValueStore object, defined as Public in the Process_Globals routine of the Starter module (initialize it in the Service_Create).
For example, if you named this object KVS, you can access values (stored permanently) from anywhere you want, like:

Starter.KVS.Put ("Sex", "Male")

If Starter.KVS.Get ("Sex") = "Male" Then


You could also use the StateManager code module.
