JavaScript problem

Stefen Howard 2 years ago in Application • updated by Richard 1 year ago 19


I am using Kiosk Browser Lockdown on a tablet locked into this site:
Most of the pages use JavaScript, including many pages that use Google Maps. I've had no problem with the scripts working *except* on pages that display 360 degree spherical images using the three.js libraries. These pages work just fine in Chrome, Firefox, and any other browser I've tested. They just won't work in Kiosk Browser Lockdown.
Here is an example page:
WebView has been updated to newest version and Android version is 5.x (Device is 400 miles away on site, so I'd need to have someone check if its important)
Do you have any idea why this might be happening?
Thank you

Possible to hide loading icon between page loads?

Running Kiosk Browser on a Samsung Android 5.0.1 in labs ahead of a wider roll out.

On page load, there is a page loading icon appearing. Is it possible to hide this?

Have tried disabling hardware acceleration based on a similar issue but no success

The circular progress bar can be hidden in Settings > Advanced > Hide Progress Bar.

Kiosk Browser Trial reloads after a few minutes

Sander Kruger 2 years ago in Application • updated by Richard 2 years ago 1

I'm testing Kiosk Browser with my app. My main concern is if the system doesn't lock up or go wrong or anything after hours of operation, so I'm letting it sit.

In variably, after a few minutes I get a message that it is the trial version and then the page reloads. After a few times, this leads to a blank screen and everthing is over.

Is it normal that the browser reloads the page? Is this the same in the licensed version?

This is by design, its a setting called "idle page timeout". It reloads the home page if the Kiosk has been idle for the specified amount of time. You can just turn the setting off if you wish, it's under Settings > General.

How to invoke Print action using javascript function on webpage ?


menu button is not clickable

Anurag 2 years ago in Application • updated by Richard 2 years ago 4

I am using Kiosk browser on a 7 inch android tablet. The menu button on the top right corner is not getting clicked on touch. some times it gets clicked after trying to click for 15 to 20 times in that area. It worked well on other devices but now on this new device it is not working.

At first I had doubt on touch screen of tablet, but later it was found that the touch screen was fine as the similar menu in top right corners of other apps like google drive, adobe reader was clickable. but not of Kiosk browser.

I even tried to uncheck hardware acceleration option in settings to solve the performance issue. But the problem persists.

Please Help.

Homepage reload resets screen brightness?

User309 2 years ago in Application • updated 2 years ago 8

Hi there.

We have an application with a javascript on the homepage. The first thing the homepage does is setting the device's brightness to 1 (Android.setScreenBrightness(1)) and then it might modify the brightness based on different application variables. But it is not unusual for the screen brightness to remain at 1 given that some devices are installed in a low-light scenario where images are being projected on walls.

Now we have kiosk-browser force reload the homepage every 5 minutes, and when this happens, the screen goes back to full brightness for a fraction of a second, and then back to the level set by the homepage. It is very short, like a "flash".

We have debugged our script but cannot find any errors. We've been trying to find the root cause for this for the past several weeks, and given that this happens when the page is being reloaded, our best guess at this point is that whenever the homepage reloads, kiosk-browser is somehow resetting the screen brightness until the script on the homepage kick-in again.

Is this possible?

As always, thank you for the support,



Screensaver black/empty transition between images

Jimmy Van den Bliek 2 years ago in Application • updated by Richard 1 year ago 10

For an unknown reason, maybe done by purpose, I've got a black or empty images displayed during 10-15 seconds between my images. Is there a way to avoid it and display each image next to the previous one without this black transition?


Hardware Requirements specifically RAM

What are the minimum hardware requirements? Will this work ok on an android tablet with 1gb ram?


Battery State JavaScript function

James Sampford 2 years ago in Application • updated by Richard 2 years ago 3

I cannot see an existing javascript function for it, but perhaps a 'state' for what the device is doing - either on charge or running off the battery - would complement the existing function that provides the battery level. I know this is already in remote management, so would be great if one could access this in the app as well :o)
