QUESTION
I have a round progress bar, made with a drawable, with values from 0-100 (included). When I load my activity, I want to animate the progressbar being "filled" with values from 0 to my desidered value. I'm using a CountdownTimer for that.
The issue is, even though I set the value to 100, the max (or any other value), the progressbar doesn't get filled all the way. Here's my code:

var countDown = setInterval(function() {
to
countDown = setInterval(function() {
With line 1 you already declared a global var countDown. Then in the function you did it again, that's why your clearInterval function won't clear the interval.
QUESTION
I have a countdown timer class which can be paused/resumed until the timer hits zero. When the timer expires, a callback function (supplied in the class's constructor) should be invoked. The problem is that when I call this.timeout(), I get an error which says TypeError: this.timeout is not a function.
This is my CountdownTimer class.

Rewrite this line: this.handle = setTimeout(this.onTimeout, this.timeRemaining); as:

I am trying to retrieve the location every 10 seconds. The problem is that the location sometimes is null, and sometimes gives back an old location. When I update the location in my emulator it is not updating live.
Code to get location:
...ANSWER
Answered 2021-Jun-01 at 15:08You cannot rely on lastLocation completely , lastLocation can be null
Also lastLocation will return the device last known location so it will not update as the device location updates until and unless some other app is requesting location (like google map)
lastLocation literally means that we are not requesting for new Location, instead we are using location which are requested by other apps, so the lastLocation can be null or old
https://developer.android.com/training/location/retrieve-current
So Instead of relying on lastLocation use requestLocationUpdates, using which you can set the time interval like after how much time you want to receive the new location, so you don't have to implement CountDownTimer
I think for your case requestLocationUpdates will be the best option
Read below docs for how to request Location updates

I am making an app which reads the SMS from the phone and sends SMS from a particular sender to a server. I want to have to app run in background using Service but its not working. The app is crashing when I try to start the Service.

Answered 2021-May-25 at 08:14We should not create a MainActivity object to call API.Instead create a Local broadcast from Main Activity and register for broadcast.When you want to call API,just send broadcast to MainActivity to trigger API.For creating local broadcast,you can check below link.

Answered 2021-May-12 at 21:41You are defining function CountDownTimer(....) within the anonymous function that is inside the $(document).ready() call. As a result the CountDownTimer function is only known during the execution of the anonymous function, and it ceases to exist when the anonymous function ends, meaning that the script inside your
To fix this, take CountDownTimer out of the $(document).ready() call - or if that is all there is in it, then consider just removing the $(document).ready() call.
So instead of this:

QUESTION
I wrote a foreground service to make sure my app can continue running when put into the background. The app needs to run in the background because after its timer elapses, it sounds a tone and vibrates to alert the user. However, when the Power or Home button is pressed, the app's timer stops running after about 15 minutes unless the phone is plugged into power. The phone was fully charged when I tested this.
Incidentally, I also set the app to NOT be optimized for battery life after reading on various sites that that would ensure that the app would continue running. From everything I read, I'm doing everything right, yet I still can't get this to work. I'm running Android 11 on a Pixel 2. I know that Google limited foreground processing for later versions of Android, but setting the app to not optimize for battery life is supposed to get around the problem, isn't it? To be safe, when the app starts, it asks the user to approve background operation:
