  1. Thanks for the tutorial man!
    But is there anyway to show message when the timer reaches a specific point?
    like if timer reaches 60sec it will show message "60 seconds" left

    Excellent video but how would you do to get the time that is finally consumed, for example 10 minutes income and when you go back to reverse the counter in minute 8, only consumed 2 minutes as I do to get the difference (10 – 8) = "2
    "

    Thanks, greetings from Mexico;

    My timer stops at 00:01 and I don't know what the problem is. Maybe someone had this?

    Future Implementation Suggestion:
    1. To show countdown in the notification bar
    2. Alarm sound to notify user that time is up. Able to select music from available music options(In Built).
    3. Able to put in multiple timer with specific timer names. For different purposes.

    Ik its a lot.. but would be fun to implement this. Happy coding 🙂

    The correct way to watch your videos are:
    1. Select the video
    2. Like the video and thank the god that this video exits
    3. Then start learning about android and coding.. 😛 🙂

    Hello. Can I ask why after I typed RelativeLayout rather than ConstraintLayout that we usually do on the countDown.xml, when i run the emulator it did not shown like the other .xml I have coded? A prompt reply is appreciated cos my project already at eleventh hour. BTW, mine is Android Studio version 3.1. It would be lovely if you can provide me a solution. ^^

    Hello, i've got an idea for part 5. When time is 0:00, then timer count up, like as stopwatch. Have a nice day!
