How can make tutorial runs once when application open for first time after install?

[deathprogrammer]

In PhoneTutorial library each time the user runs the application, tutorial will be displayed. How can I make it so that only the first time the application runs, it see?

@deathprogrammer You Can simply use SharedPrefrences Class and define a boolean to learn first run of application.

import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.RandomAccessFile; import java.util.UUID;

import android.content.Context;

public class Util { 
    // =========================================================== 
    // 
    // =========================================================== 

    private static final String INSTALLATION = "INSTALLATION";

    public synchronized static boolean isFirstLaunch(Context context) {
        String sID = null;
        boolean launchFlag = false;
        if (sID == null) {
            File installation = new File(context.getFilesDir(), INSTALLATION);
            try { 
                if (!installation.exists()) {
                launchFlag = true;                          
                    writeInstallationFile(installation);
                } 
                sID = readInstallationFile(installation);

            } catch (Exception e) {
                throw new RuntimeException(e);
            } 
        } 
        return launchFlag;
    } 

    private static String readInstallationFile(File installation) throws IOException {
        RandomAccessFile f = new RandomAccessFile(installation, "r");// read only mode
        byte[] bytes = new byte[(int) f.length()];
        f.readFully(bytes);
        f.close();

        return new String(bytes);
    } 

    private static void writeInstallationFile(File installation) throws IOException {
        FileOutputStream out = new FileOutputStream(installation);
        String id = UUID.randomUUID().toString();
        out.write(id.getBytes());
        out.close();
    } 
} 

Usage (in class extending android.app.Activity)

Util.isFirstLaunch(this);
