In todays tutorial I'm going to run you through how to build a simple count up timer app using Java and Android Studio. Our simple tutorial app will have a few basic buttons to start, stop and reset the timer. We will build and alert dialog to confirm when the timer is reset. Our basic timer will count up from zero to infinity and beyond 🚀🚀🚀.

This is exactly what I was looking for. An experienced coder to speed up my learning curve in android studio. I watched another tutorial and the guy never wrote a single line of code... I was sad and confused until I found your video. This shows exactly how an experienced coder would use android studio and I thank you. I am surprised this video barely has any views and likes and comments. I hope this blows up.

This is great, would love a follow-up where you show how to let the app run in the background even if we switch to another app or close the app.

Thank you alot for this tutorial but i was wondering how can i return the time after the timer stop as integer so i can use it for another calculations?

@CodeWithCal 2 жыл бұрын

We keep the time as the double variable. So you can return that. Just cast it to an int like we do in getTimerText()

If i want only seconds to show counting it only goes uptp 60 and gets reset, but i want it to continue further 60 as well, how can i do that...plz help P.S. I have used same code and just removed hours and minute parameters

@rubinho388 2 жыл бұрын

5:45 how did you choose these values 86400, 3600 and 60? I understood the result but I dont know the logic behind those numbers...Is this some sort of formula for getting seconds, minutes and hours and then resetting it when it gets at a limit value?

@CodeWithCal 2 жыл бұрын

Yeah so that value is total milliseconds and those numbers calculate the hours seconds etc from the milliseconds

You had a class where the timer didn't stop even when the user turned off the smartphone, I can't find this class in your video collections. Can you repeat the class? I'm new to JAVA, I need to understand java a lot and it takes months even years, I can't want to like KOTLIN right now.

How do you start the count up from a given time?

@CodeWithCal 3 жыл бұрын

You should be able to set the variable: Double time = 0.0; To your given custom start time.

This is great, but one issue when screen rotate or app is closed, timer start reset automatically and start from 0.

@CodeWithCal 3 жыл бұрын

You are right, for simplicity sake the timer is running on the main / UI thread. Putting the timer on a background thread is the way forward. Maybe a tutorial on the topic would be good 🤔

You still Java to write Android code and not Kotlin? And then put all the logic in your Activity? In the year 2020? :| #BadExampleToFollow

@CodeWithCal 2 жыл бұрын

Firstly Java still has it's place. Secondly this is a small project and tutorial so who cares where the code is. You are right, for bigger projects it is worth splitting most logic out of your activity. But man I'm calling you out for sounding like a massive elitist.
