check it on your devices and tell me "Do you see black screen or played game" , and if it is black screen , why?
Help me please

There probably is an error with the application that the user can't see. I advise you to run this in an emulator or link your device to your pc and emulate it locally. When you have the emulator (or device linked up) ready, you can debug and see exactly what the error is.
If you have trouble on certain devices, check your SDK level and test on multiple emulated devices.
Chances are the problem is a deprecated item or a version level error.

iPhone doesn't show up using Adobe Animate CC

Hey everyone so I have an iPhone 4(I know old) and I am trying to publish my app using Adobe Air for IOS 26.0. My computer and iTunes recognizes the apple device perfectly but when I try to publish it in Animate where it says "Install application on connected IOS device" mine doesn't show up at all. I tried restarting the device and computer and tried multiple USB cables as well. Nothing is working. Please any help is appreciated.
Updating AIR won't fix this as the process of detecting a device is through Animate, not AIR. I can confirm Animate can still detect iPhone 4. Mine is running iOS 7.1.2
Try connecting in this order:
Launch Animate
Unlock your iPhone
Connect your iPhone via USB
Debug Menu > Debug Movie > On Device via USB > Refresh Device List

How to get the ID to register a test device for unity ads

How and where can I see this number needed to register a test device in unity ads?
it depends wheter its what phone you are using if its an Android based phone for example you can find that number behind the battery usually or with simple commands on the phone itself,
e.g. (Android) https://www.verizonwireless.com/b2c/findDeviceId/helpOverlay.jsp?pageName=androidPhone
(Iphone) https://support.apple.com/en-il/HT204073
that number just tells unity that any ads running on that device are test ads and treat them so.
For Android device.
Open google settings from device.
Navigate to services->Ads.
Advertising id for your android device will there.

Canvas Drawing lines are very slow in phonegap with android

I am using phogegap to develop my drawing app. When user touch with the finger and move around, multiple lines can be drawn. But this app is very slow/slugging in android emulator and android device.
The same coding work fine for iPhone Simulator.
Note: In android emulator I can see the following messages.
[[Miss a drag as we are waiting for WebCore's response for touch down.]]
Any suggestion.
Try unplugging the android handset after installing the app on it. I have found that my apps are generally much slower (even on a handset) when they have an active debugging session connected to the device. In other words, just run the app without a debugger attached and see if its any faster.
Phone gap is never going to be as fast as a fully native application. If you are going graphics intensive stuff then prepare to be disappointed...

Xcode for Dummies: Can I simulate an iDevice camera?

So, is it possible to simulate the iPhone (arguably future iPad) camera in Xcode using the built in camera on my MacBook?
I read some similar posts, but from the answers I feel it was left up in the air if it can or can not...
Thanks in advance!
No, you cannot. There is no camera app installed, and calling the camera related classes normally creates a crash. You can however sync photos to it.
Short answer: Never use the simulator. It's a joke. I think the only reason they put it in there is so that people can fiddle with stuff before they pay 100 dollars for the developer program.
You cannot simulate the camera using just iOS SDK frameworks while staying within the app sandbox.
However, on the Mac Simulator, you CAN reach outside the sandbox and connect to another camera server Mac application or process, which you would have to develop. So it's technically possible using Mac frameworks and processes outside of the iOS environment for debug purposes to get a camera view inside a Simulated but-non-pure iOS app. Not for dummies though...

Is it possible to display my iPhone on my computer monitor?

As the title says, is this possible?
I want to "mirror" my actions on the iPhone so it shows on the computer monitor.
We've seen this on the Apple key notes, but I am not sure if this feature is public.
Many screencasts displaying an iPhone application simply use the iPhone Simulator, which is one option.
You can also take screenshots on the phone by quickly pressing the menu and the power/sleep button at the same time. The image is then saved to your "Camera Roll" and easily transferable to the computer
The other way is only possible with a Jailbroken phone - Veency is a VNC server for the iPhone, which you can connect to with a regular VNC client.
The latest SDKs (beginning with 2.2, I believe), include TV-Out functionality. With a special cable connected to the iPhone dock connector, a program can send RCA signals representing its current screen contents through the iPhone->RCA cable. If you have a TV Tuner for your computer (i.e. I have an EyeTV Hybrid) with RCA inputs, you can display the screen contents of your iPhone directly in the TV viewer.
If your iPhone is jailbroken you can use DemoGod
use screensplitr on jailbrocken iphone/ipod touch it works
Release notes iOS 3.2 (External Display Support) and iOS 4.0 (Inherited Improvements) mentions that it should be possible to connect external displays to iOS 4.0 devices.
But you still have to jailbreak if you would mirror your iPhone screen...
