Android Question Saving a variable in memory

[red30]

Public const=0 As Int
There is a public const that changes its value in the programme. How can I save this value in memory when closing the programme in order I could use it when open the programme the next time?

Is there an easier way? I need to write only one integer type value. And every time you start the program to watch it.

I have a variable: Public const=0 As Int
In the program, I changed it to: const=1
How do I save it and the next time you start reading?
It can be an example please!

Most simplest example: (from B4A IDE info)

Write it:

File.WriteString(File.DirRootExternal, "1.txt", "Some text")

Read it:

Dim text As String
text = File.ReadString(File.DirRootExternal, "1.txt")

See File object for more options

A type integer?
Where is it being stored?

You save an Integer as String and parse to Int when read from file; it can be stored on internal memory or external (SD) memory; please check the Beginner's guide at https://www.b4x.com/android/files/guide.zip (File Object: Page 321)
