i have an array like this

array []=[1,1,1,0,0,0,0,0,1,1,1,0,0]

so i will handle flashlight via that array

if array item is 0 i will switchoff

if array item value is 1 i will SwitchOn

how can i do this?

i tried this

but for does not work with window.plugins.flashlight

what is problem with this?

i control parameteres everything is ok 

 

var on = [ true, false ];

 function flashlightDemo()

{ for(i=0;i<on.length;i++)

{

  if (on[i])

{

        window.plugins.flashlight.switchOn(); 

  }

else

{ 

       window.plugins.flashlight.switchOff();

        }}}

Hello,

I have just tried the code from your last post in the Flashlight plugin demo and I think it works as expected. Keep in mind that this plugin will only work on an actual device that has a flash light.

I have attached the modified demo project for reference. Here is the code I added in scripts/demo.js:

switchOnOffArray: function () {
    var on = [ true, false, true, false, true, false ];
    for(i=0;i<on.length;i++) {
          if (on[i]) {
                window.plugins.flashlight.switchOn();
          }
            else
            {
               window.plugins.flashlight.switchOff();
            }
    }
},

And in index.html I added one more button:

<button data-role="button" class="button" data-bind="click: switchOnOffArray">Switch ON/Off From Array</button>

Deploy the project on your device, go to the Demo tab and tap the Switch On/Off From Array button. The flashlight should flash 3 times.

The only difference is that I added some more true and false values for 3 flashes. Try the attached project and let me know if it works on your side. I have tested this on Android Nexus 5 with Android 5.1.

you just move

that array (var on = [ true, false, true, false, true, false ];) from outside function to inside function

now it works .thank you

 

i want to load that array(on array) from database

so i will make ajax call

should i make ajax call inside that function?are there any sample that contains ajax call?

 

i  want to make animation with many device

for example i want to make animation at 22:00 hours

so every device  have different time 

what should i do?

should i use server time?i want to start al device flash on on same time and off at same time 

synchrony is very important for me

Hi Hüseyin,

It isn't possible so synchronize devices by making AJAX calls, as these calls can take different periods of times on different devices, based on internet speed, device capabilities, etc. 

As a development tool, AppBuilder cannot offer a way to implement your requirement. You would need to further research how to sync devices system time or how to get two devices to communicate with a minimum lag.

You may need to implement a custom plugin of your own to wrap this functionality from a native implementation. Some discussions on the topic of syncing device time are available here:

Sync Android devices via GPS time?

How can I get the “network” time, (from the “Automatic” setting called “Use network-provided values”), NOT the time on the phone?

hi

i do my own way 

 for example if administrator want to animation start at 20:30 with on= [true,false,true,true,false....] array

i 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
