I am developing Phonegap Application and my application has scenarios where camera is used very frequently.
In my application I have used custom camera plugin (https://www.npmjs.com/package/cordova-camera-custom) to take picture and use it in my application.
Now when I capture images from this camera 30 times by opening camera and capturing again and again the app goes to crash.
The app just crashes so I am not able to identify the root cause of the crash.
I am not an iOS Programmer though I have tried to check the plugin code but I was not able to find the cause.
You can even check the plugin code on your end if needed.
I have also posted this issue to DevExtreme, the framework which I am using to develop hybrid applications at following link:
https://www.devexpress.com/support/center/Question/Details/T480068
and they found that issue indeed is related to memory shortage. The error message was with bug_type: 298 and fault cause: vm_pageshortage.
Please help me on this, I am struggling on it since long before.
Any Help is greatly appreciated.

I created a completely new and empty FMX app, tried it using Delphi 10.3.3 and 10.4.0 (patch 3), and when installed on Android 7.1.2 devices (tried two different ones and the official simulator VM), after the splash screen this error message appears:
'java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.contains(java.lang.CharSequence)' on a null object reference'
The error message box flickers quickly (endless loop) and gets slower and slower and after a minute the complete device doesn't react anymore and I can only hard reset it.
I found this thread, so I'm not alone. They say it worked until Delphi 10.1.2. There are also many other similar search results.
Is there any solution? On other Android versions it works well.
Or what can I try to get more information about what causes it?
Do you know a good candidate for an app made with Firemonkey that I could download directly and try out on the device?
Now there is a fix available at quality.embarcadero.com!
Just one line has to be added to 'Androidapi.JNIBridge.pas'. I'm not sure if I should copy it here... Will update this answer when it is released.
I'm working on a project using IBM Worklight and any time I build and deploy my project on any simulator or device, I have this busy indicator spinner in the middle of the screen. Its always there, on every page and its there in the ios, windows, web and android simulators as well as one android device we've tested on. Has anyone seen this before and if so how would I get rid of it.
Jquery-mobile was the problem, it was continuously displaying the indicator for seemingly no good reason. Deleting Jquery mobile fixed the problem
I already used the native worklight loading.It is very good and I tested it on different platforms, devices. But it is necessary to close it when you leave the function that opened it.
Example:
var busyInd = new WL.BusyIndicator ("content", {text: "Please wait..."});
function consult(){
busyInd.show();
//impl
busyInd.hide();
}
I've got a terminal application that needs to take a webcam picture and then perform some processing on it. I'm having trouble getting it to initialize. There's a fairly complete demo with an app called MyRecorder in the Apple docs that uses QTKit, which I was able to make work fine. I was also able to modify it to grab a single frame instead of a stream.
When I move this to a terminal application, the startRunning of the QTCaptureSession command simply does nothing. There are no errors, and everything reports as successful, but my webcam doesn't light up, and no frames are captured.
Any idea what's going on here? Are there any kind of security restrictions, or other kinds of restrictions that would prevent the QTCaptureSession from working?
So switching to AVFoundation solved my problem. I'm still not certain what the issue is, but for now using AVFoundation seems like the way to go since it was designed to replace QtKit anyways.
Is there any way in which the usage of the camera of the iPad2 can be restricted only to my application? even if it is using i tunes.
could not find any code related to it. some code would be helpful.
There's no way to achieve this. I think it could be done with quite a bunch of hacking if you were developing for Cydia, but I'm not sure ever then. If the user quits your application or switches from it, the system will make the camera available to any other app requesting it.
I am developing an iPhone game, and I will implement Game Center in it.
Apparently, I need to do some configuration with my application in iTunes Connect first. Therefore I have to "create" my application in the iTunes Connect page, right? But, how do I do that without getting Apple's staff review my app since I am still working on it?
I tried making a new app like normal, but it asks me for a bunch of stuff like screenshots etc, but I have none to offer in the first place...
Fixed. It seems they won't even review it if there is no binary uploaded yet.
