`addVolumeListener` is fired twice when press volume key
See original GitHub issueI just tested android device only.
There is a problem that the addVolumeListener
is called twice when the sound mode is “music”.
my code snipppet is here
componentDidMount = () => {
this.volumeListener = SystemSetting.addVolumeListener(this.setVolume);
};
componentWillUnmount = () => {
SystemSetting.removeVolumeListener(this.volumeListener);
};
setVolume = currentVolume => {
console.log("call setvolume");
this.setState({ currentVolume: currentVolume.value });
};

Hi. Did anyone solve this issue?
This solution does not work for my problem. I start the camera, thanks to a button, a self-timer starts, then after the recording starts. The problem with
shouldComponentUpdate
is that I don’t care about the rendering of the component. Thanks to theVolumeListener
, I want to be able to start recording with the volume button. With a multiple call from the listener, it prevents me from doing what I want and the shouldComponentUpdate() doesn’t work because it only concerns rendering.Sorry I’m French and I must have made some mistakes.
Edit : I have found a solution but it’s not a good solution
