Hi ,

i want to develop animation app.

All device's (which installed app) flashlight will do that animation at specific time.They must be start at same time.

i will give array about off-on.All device must be on at same time and then off at same time.

So i do ajax call for to get animation begin time.

animation start at sametime for all devices.if time does not ready all of them wait when time is ok all devices start at same time .i give same array(whic include on-off info) but same devices get off when other is still on...How can i handle this?this is my code and descripton

receivedEvent: function (id) {
var on = [true,false,true];
var todayDate = (new Date().getTime()/1000);
var dateGSF = new Date(2020,11,25);

$.ajax({url: "URL...",
async: false,

success: function(result){//

var on1=result.split("?")[1];
on=on1.split(",");//this is on-off information array like this var on = [true,false,true]

window.localStorage.setItem("tarih",result.split("?")[2]);//this is animation start time
window.localStorage.setItem("dizi",on);

var serverTime=result.split("?")[3];//i get server unix UTC time.Maybe device time is wrong.
window.localStorage.setItem("ileri_geri",(todayDate-(serverTime)));// ileri_geri is difference between server time and device time.So if device time

//was more or less i will calculate.So i want to start animation with same time

flashlightDemo1(on);
}});
},

function flashlightDemo1(on) {

var ileri_geri=window.localStorage.getItem("ileri_geri");//difference device time and server time for synchronise

var tarih=window.localStorage.getItem("tarih");//this is animation start time
var baladiMi=false;//if animation start then i set this to true

if (parseInt(new Date().getTime()/1000)>(parseInt(new Date(tarih).getTime()/1000)+parseInt(ileri_geri))) //if animation time is ok let animation begin
{
flashlightDemo(on);
baladiMi=true;
}
var Fsettimeout=setTimeout(flashlightDemo1,100,on);
if(baladiMi){
clearTimeout(Fsettimeout);//if animation start clear interval
}
}

and this is my plugin

i make work around solution but

window.plugins.flashlight.switchOn();

this not work inside if--while....

?what is problem with this?

function flashlightDemo(on) {
var tarih=window.localStorage.getItem("tarih");
var ileri_geri=window.localStorage.getItem("ileri_geri");

while(2>1){
alert('while başı');
for (;;) {
alert('for basi');
if(parseInt(new Date().getTime()/1000)>(parseInt(new Date(tarih).getTime()/1000)+parseInt(ileri_geri)+parseInt(index*50)))
{
alert('if ici');

if ( on[ index ]==='true') {
alert('on basi');
window.plugins.flashlight.switchOn();
index++;

break;
alert('on sonu');

} else {
alert('off basi');
window.plugins.flashlight.switchOff();
index++;
break;
alert('on sonu');

}

i do my own way for example if administrator want to animation start at 20:30 with on= [true,false,true,true,false....] arrayi check if time is 20:30 if yes i start it for first item(on[0])and then i check time again if time is 20:30+X(difference two action time) if time is ok then i process it for seconde item(on[1]) this algoritm good looks but when i call switch on or off function it does not work

calling this function does not work

flashlightPlugin(on[ index ]);

function flashlightDemo(on) {
var tarih=window.localStorage.getItem("tarih");
var ileri_geri=window.localStorage.getItem("ileri_geri");

while(2>1){

for (;;) {

if(parseInt(new Date().getTime()/1000)>(parseInt(new Date(tarih).getTime()/1000)+parseInt(ileri_geri)+parseInt(index*20)))
{

flashlightPlugin(on[ index ]);
index++;
break;

.....................

and this is flashlightPlugin(on[ index ]);

function flashlightPlugin(on) {

if ( on==='true') {
window.plugins.flashlight.switchOn();
}
else
{
window.plugins.flashlight.switchOff();
}
}

function flashlightPlugin(index) {
var on=window.localStorage.getItem("dizi");
on=on.split(",");

if ( on[index]==='true') {

alert('on');
window.plugins.flashlight.switchOn(onSuccess, onError);
}
else
{
alert('off');
window.plugins.flashlight.switchOff(onSuccess, onError);
}

.....................

i handle time and call flashlightPlugin function.it work

if value (on[index] ) on it alert on

if value off it alert off

but it call window.plugins.flashlight.switchOn(onSuccess, onError); that function it does not work

i added

this function

var onSuccess = function (msg) { alert(msg) };
var onError = function (msg) { alert( msg) };

but it does not give any alert......

Hello Hüseyin,

You did not say if you test this directly on a device or in the companion app. Note that custom plugins do not work in the companion app and you need to deploy the app directly on the device.

Additonally, if you are using the Windows client or the Visual Studio extension and your app is running on a connected device, you can check the Output window for any runtime errors.

You can learn more about the debugging options in AppBuilder here:

FlashlightPluginTest.zip

Hello Hüseyin,

I tested the plugin on my side on an Android 4.4.4 device and an iPhone 5s and the flashlight switched on and off as expected. I am attaching my test project to this message. Am I missing anything out in trying to reproduce the issue?
