Writing and Reading to/from text files

[Kamac]

Hi.


Could someone give me straight-forward two examples of writing and reading to/from text files?

1. Write "a" to text file called "text.txt"
2. Read all strings from "text.txt" and store them into array.

@additional 3. After doing 1, how to add another "a" to "text.txt" so it'll contain "a
a"

- basically, extending "text.txt" in more strings.

Your only option is to use a tool such as adb or ddms.

Intent1.Initialize(Intent1.ACTION_VIEW,"file://"& File.DirInternal & "/PT930SA.txt")

StartActivity(Intent1)

Thank you.

Move your file to File.DirRootExternal. The internal folder is not accessible for other applications.
