Java Keytool Commands for Creating and Importing

These commands allow you to generate a new Java Keytool keystore file, create a CSR, and import certificates. Any root or intermediate certificates will need to be imported before importing the primary certificate for your domain.

Generate a Java keystore and key pair

keytool -genkey -alias mydomain -keyalg RSA -keystore keystore.jks -keysize 2048

Generate a certificate signing request (CSR) for an existing Java keystore

In the pass, to build the timer task, for example: to show count down timer on TextView or show current position when play the music or video use MediaPlayer, I use TimerTask or Timer object as the best choices.

This is the old source code

timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
    @Override 
    public void run() { 
 runOnUiThread(new Runnable() {

                        int targetWidth = imageView.getWidth();
