I am working a wp8 app which can read some different types file.Then launch them in a simply way.Like we can launch mp3 using MediaPlayerLauncher .But I failed.Any help will be kind to me.Thanks
I assume that you managed to use ExternalStorage. Firt of all you are not able to see this (mp3) files because they are reserved. What you can do is to change extensions to them and copy to InternalStorage. As you have done that you can play them well with MediaElement or BackGroundAudio.
Also it's not possible (for now) to play directly from ExternalStorage (SD card).

I want to transfer information from my website to my electron program by using a link that has some data in it (like myprogram://data). But can't seem to find any info on the internet about this. Any help would be gladly appreciated.
Thanks!
You need to register your app as a protocol handler using app.setAsDefaultProtocolClient
app.setAsDefaultProtocolClient("myprogram")
On Windows, when the "myprogram://data" link is clicked, a new instance of your application will be launched and the arguments will be included in process.argv
Use app.requestSingleInstanceLock if you don't want multiple instances of your app to be running
On macOS, you can get the arguments using the open-url event
I'm developing an VR Video Chat application using Agora.io api and Unity3D Engine, in which a main user streams his webcam from a standalone Pc to users equippped with an Oculus device.
As soon as I try to upload the VR app to the Oculus Server, I got that error:
This app uses permission(s) that are not compatible with this device: android.permission.CAMERA.
How do I overcome that issue?
Any suggestions?
I haven't programmed for Oculus yet but here are some ideas:
First you may try just to set android:required=“false” in the manifest to see what happens?
Secondly check the official Oculus documentation here to see if helps? https://developer.oculus.com/blog/tech-note-android-plugins-and-permissions/?locale=en_US
"You will need to modify your Android Manifest file. Because the Oculus Quest doesn’t have cameras (well, none that can be used for this demo) we will get rid of the camera use requirement ( ) located on line 9 in the folder Assets/Plugins/Android/AgoraRtcEngineKit.plugin "
This is a quote from this quick start tutorial which will get you up and running with Agora.io Video chat and Oculus Quest. It explains how to stream your webcam from a standalone PC to Oculus Quest. https://medium.com/#jake_agora.io/live-realtime-video-to-vr-oculus-quest-6bbb74e4fc63
Just in case anyone else falls into this. The solution posted where you remove the entry from the Agora included manifest doesn't work anymore, and I can't identify where its being added from, perhaps Agora can post a solution. The only way around it is to export from Unity, edit the Manifest to remove the unwanted camera permissions and then build in Android Studio.
I'm currenly writing an app where I need to use custom sound for toast notifications (which is sent from cloud). MSDN states that the audio clip must be stored in the app's installation directory or local storage folder. So how is this done?
I tried the CopyToIsolatedStorage() code sample from How to play background audio for Windows Phone. It fetches the audio clip correctly but when the toast should be shown the device won't play any audio or even show the toast which indicates that it can't find the audio clip correctly. In the app, I have a method which shows contents of the push notification when the app is in foreground. From there I can see that the toast notification is sent and received correctly with toast.mp3 sound tag. So the problem must be in the app but I can't figure out what I did wrong.
Tl;dr version:
I want to change toast notification sound, my device is running WP8 with Update 3 and I have a 5 sec long mp3. I can't figure out how and where I should put the audio clip.
I dont think you need to copy the sound to isolated storage, just put it in your main project and set it as content. Then in your Push just reference it.
<wp:Sound>toast.mp3</wp:Sound>
Or if it is in the Assets folder in your project do
<wp:Sound>Assets/toast.mp3</wp:Sound>
Note: This only works for Windows Phone 8 Update 3 and later, works fine for all Windows Phone 8.1.
So the problem was that I blindly assumed one can reference to the audio clip with just <wp:Sound>toast.mp3</wp:Sound> or new Uri("toast.mp3", UriKind.RelativeOrAbsolute), as in the MSDN tutorial, when the file is copied to the root of the isolated storage but this isn't the case. You'll have to include the directory where the clip is in your project to the path, in my case Audio\. Thaks goes to WiredPrairie for pointing this out.
So to wrap things up:
Copy the audio clip which you want to use to the isolated storage with CopyToIsolatedStorage() from How to play background audio for Windows Phone and follow the instructions in Using custom sounds in toasts on Windows Phone 8 Update 3 . And remember to include the directory structure to the path of the clip or put the clip in the root of your project.
The default camera showing up is the back camera using Camera getCamera
I want to know how to switch to front camera.
Also Camera names length is showing only length as 1 and not 2 , but i am having a front and back camera on galaxy tab, so i think it should show 2 names.
Please let me know a way out to this.
I am using air 3.1 , which is the latest version at present.
and the application is built in Flex 4.6 version
Air for Android only supports the back facing camera -- at least that might have been the case until very recently.
I have downloaded and saved the AS3 API reference from Adobe. On my local copy of the docs, it says this about the Camera.names property:
On Android, only one camera is supported, even if the device has more than one camera devices. The name of the camera is always, "Default."
However, when I look at the docs online, that comment is no longer there. So maybe Air 3.2 (released yesterday) now supports both cameras on Android!
Online docs:

I created an Air desktop app with Flash CS 5. Usually Windows (XP) is opening an application (like Firefox) with the latest set size and position.
For my installed Air app it's always just the default one.
How to start it with the latest used size and position?
Thanks.
Uli
hope this will work for you:

You need to save a record somewhere that remembers the window's size, and possibly position. If your app has a preferences file, this would be an ideal place to store that information. Then, whenever your app starts, it checks for this information and resizes the window if any values are found.
Most popular programs include this feature (and don't even mention it, since it's pretty basic UI), but it's done intentionally and not as a default for every application. Thus if you want it, you have to program it in.
You can read and write to application.xml. You'll find there and nodes.
file = new File( File.applicationDirectory.nativePath + "/META-INF/AIR/application.xml" );
Adobe restrict writing access to application diractory but this trick is useful if you don't want to create a separate config file in app-storage:/ folder, which is of course prefered.
