Create a function that fires only once after app is installed on phone

I'm developing a mobile app using ApacheCordova/Phonegap. I need a function that sends a SMS to me once per install. If I put my function on "DeviceReady" it will be run each time the app opens. Is there any solution for a function to be run when app is installed OR when it runs for first time?

Any suggestion would be appreciated.

I added a field to the localstorage and on startup just check if that field exists. So something like this:

if (window.localStorage.getItem("installed") == undefined) {
   /* run function */
   window.localStorage.setItem("installed", true);
}

Edit: The reason I prefer this over the other methods is that this works on iOS, WP, etc as well, and not only on android

Use some boolean value if its true don't call that function other wise call that function example is here

if(smssent!=true)
{

//call sms sending method

}


else

{

//just leave blank or else notify user using some toast message

}

Note:-the boolean value store in some database like sharedprefernce or sqllite, files....

Check if it is the first time with a method and then perform the action if that method determines that it is the first time.

Ex:

isFirstTime() Method

private boolean isFirstTime()
    {
    SharedPreferences preferences = getPreferences(MODE_PRIVATE);
    boolean ranBefore = preferences.getBoolean("RanBefore", false);
    if (!ranBefore) {

        SharedPreferences.Editor editor = preferences.edit();
        editor.putBoolean("RanBefore", true);
        editor.commit();
        // Send the SMS

        }
    return ranBefore;

    }

You may want to add it to your onCreate()

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    topLevelLayout = findViewById(R.id.top_layout);



   if (isFirstTime()) {
        topLevelLayout.setVisibility(View.INVISIBLE);
    }

This should be what u are searching for:

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
if(!prefs.getBoolean("firstTime", false)) 
{
// run your one time code
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean("firstTime", true);
editor.commit();
}
