Determine if Android app is being used for the first time

Question

I am currently developing an android app. I need to do something when the app is launched for the first time, i.e. the code only runs on the first time the program is launch

Answer 1

You could simply check for the existence of an empty file, if it doesn't exist, then execute your code and create the file.

e.g.

if(File.Exists("emptyfile"){
    //Your code here
    File.Create("emptyfile");
}
