BackgroundTimer.stopBackgroundTimer() not stopping timer in iOS
Hello!
I checked all the other issues related with this and the problem still persists in iOS:
componentDidMount
if (Platform.OS === 'android') {
this.interval = BackgroundTimer.setInterval(() => {
this.recurrentTask();
}, 1000);
} else {
BackgroundTimer.runBackgroundTimer(() => {
this.recurrentTask();
}, 1000);
}
componentwillUnmount
if (Platform.OS === 'android') {
BackgroundTimer.clearInterval(this.interval);
} else {
BackgroundTimer.stopBackgroundTimer();
}
It works perfectly in Android but in iOS the timer doesn't stop. I tried the same approach from Android in iOS, which works but not when the app is in background, and I also tried the "Crossplatform" which also doesn't work. This means that the timer is not being released in iOS.
RN version: 0.58.4 react-native-background-timer version: 2.1.1
that correct... not stops in iOs and in android
@LuisBonsembiante In Android it works perfectly for me. Android 8.1
In the beginning It looks like it works, but if you close the app and wait 30 - 60 minutes, you will see the battery is drain cause problem with release the wake lock.
If someone know how to release it, it will be very helpful.
I also look at the code and it looks like it should free it, but most of the time is not release it.

@roysG Thanks for your comment. I'm only testing with 1min, 3min and 5min in background. For those timespans, well I think there is no solution. The SO is free to even kill the app: https://dontkillmyapp.com/problem
Hi, I think you did not understood me, the app is not killed me. The awake lock is still running in the background and drain the battery, even i close the app.
The second problem, When i turn off the screen there is lag(delay) in the gps location. See also reference here: https://github.com/ocetnik/react-native-background-timer/issues/13
Please assist, thanks. (By the way, awesome library!)

Oh okay I got it! Yes I didn't know that. So it means that if the app is not closed I still have those locks draining the battery... Ok so it's even worse than I expected.
Yes, my users not happy :( Maybe you know how to fix it?
And also about delayed gps when the screen is off ?
@roysG I'm not the developer of this library and I'm not familiar with the codebase. I've just reported a problem that I'm having right now.
This solution work for me
For Starting timer must do like this.
startTimer = async () => {
this.setState(() => ({ timerValue: TIMER_INTERVAL }));
if (isAndroid) {
await BackgroundTimer.runBackgroundTimer(() => this.updateValue(), 1000);
} else {
await BackgroundTimer.start();
timer = BackgroundTimer.setInterval(() => {
this.updateValue()
}, 1000);
}
}
For stopping timer must do like this.
resetTimer = async () => {
this.setState({ timerValue: 0, timerDisplayValue: '' });
if (isAndroid) {
await BackgroundTimer.stopBackgroundTimer();
}
if (timer) {
await BackgroundTimer.clearInterval(timer)
}
await BackgroundTimer.stop()
}
i've found some solution, but i'm not sure how much is it correct
modify index.js as 1)
this.uniqueId = 0
this.callbacks = {}
this.bool = true <--------- ADD THIS ONE
backgroundClockMethod(callback, delay) {
this.backgroundTimer = this.setTimeout(() => {
if (this.bool) { <--------- ADD
callback()
this.backgroundClockMethod(callback, delay)
} <--------- ADD
}, delay)
}
stopBackgroundTimer() {
this.bool = false <--------- AND THIS LAST
this.stop()
this.clearTimeout(this.backgroundTimer)
}
and use for IOS and ANDROID
BackgroundTimer.runBackgroundTimer(() => { //CODE HERE }, delay)
BackgroundTimer.stopBackgroundTimer()
@davidcunha try this solution from stackoverflow, worked for me on android and ios https://stackoverflow.com/questions/54833140/react-native-background-timer-never-stops/56473096#56473096

If i set a timer of 60 seconds and i background the app in ios the app gets terminated after 30 seconds.
