how can I let my application auto look for a new update in the startup? like if I'm making new changes in the android studio and I start my application it needs to check for updates and then if there are new updates then it needs to download it and then start up the application.

I have one my old java project where I had that function. What you need:

  • Simple website where to upload text file with newest version and also newest version's jar file. I recommend 000webhost.com.

  • *.bat file that replaces old *.jar file with new one and then runs that jar.

  • Java application that downloads that text file from that website, gets the newest version and compares with current version. If your current version isn't the newest then launch that *.bat file and terminate currently running Java application.

Done!

How *.bat file should look like:

copy C:/User/Matrx007/Documents/AutoUpdate/autpupdate_v1.0.2.jar 
     C:/User/Matrx007/Documents/AutoUpdate/autpupdate.jar
java -jar C:/User/Matrx007/Documents/AutoUpdate/autpupdate.jar
