I'm trying to play a video using the AVPlayer and an AVPlayerItem.
Im using following code:
asset = AVAsset.FromUrl(new NSUrl(GalleryURL));
playerItem = new AVPlayerItem(asset);
playerItem.AddObserver(this, (NSString)"status", NSKeyValueObservingOptions.OldNew, IntPtr.Zero);
player = new AVPlayer(playerItem);
the property GalleryURL is one of the following:
1.) When saving a video to the gallery, i get this url from the ALAssetsLibrary instance call: WriteVideoToSavedPhotosAlbum(url, (galleryPath, error) => { ... });
where "galleryPath" is something like this:
file:///var/mobile/Containers/Data/Application/0D510365-4A63-425B-840C-A4E18BD870A8/Documents/...
this works fine, I can create the AVAsset and retrieve the AVPlayerItemStatus, especially the status "ReadyToPlay", via the added Observer.
2.) However when I retrieve a Video from the gallery, the url looks different:
assets-library://asset/asset.MOV?id=EB9FC214...
and in this case I'm not able to retrieve a working AVAsset
How can I get part 2 to create a working AVAsset, which I can use for video playback? I believe this works in iOS versions prior to iOS 11.
Landu Lu - MSFT helped me to find the answer:
He told me that there are 2 paths that I receive from the UIImagePickerController:
The asset-library path could not be used, maybe I have to remove the "assets-library:" part? but the path beginning with "file://" could be used. The problem of the plugin was, that the start of the url was cut off, there was no "file://" at the beginning. I manually added this string and it works! Thanks alot!

I found out, that the requirements for showing a notification consist of setting a content-title, a context-text and a small icon. The last of which I do not do. Unfortunately, I don't know, how to provide a small icon especially in unity.
Original Question
I'm currently trying to show a notification from a unity-instance via android. I want to show the notification, when the user enters a specific gps-area. Thus, the script should run, when the app is paused. That's why I want to use the android-functionality.
With this code, I currently try to show the notification manually:
public void createNotification(){
NotificationManagerCompat nManager = NotificationManagerCompat.from(curContext);
NotificationCompat.Builder builder = new NotificationCompat.Builder(curContext, CHANNEL_ID)
.setContentTitle("Stuff")
.setContentText("MoreStuff")
.setPriority(NotificationCompat.PRIORITY_DEFAULT);
nManager.notify(1551, builder.build());
}
The context is stored in a static variable and is set, when calling the method.
The function is called in C# with:
PluginInstance.Call("createNotification");
The PluginInstance works, the function can be called, but I get the error:
AndroidJavaException: java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/core/app/NotificationManagerCompat
I found the solution for my problem: I used the Unity Android Jar-Resolver in which I provided the *Dependencies.xml (Where the * presents the Name of my project). In the *Dependenices.xml I specified: <androidPackage spec="androidx.appcompat:appcompat:1.1.0"> and run through the steps, provided in the Tutorial of the Resolver.
Afterwards, multiple dependencies appeared in my /Assets/Plugin/Android-Folder, which were successfully transferred to the app, when building it.
I'm trying to play a HDHomeRun Connect Video source from a url in the following format: http://x.x.x.x:xxxx/auto/v4.1. This video source is an MPEG2 video encoding and AC3 audio encoding.
I've tried using the Samsung Tizen.TV .NET sample with the following source but the video never plays.
_player = new Tizen.Multimedia.Player();
var mediaSource = new Multimedia.MediaUriSource(uri);
_player.SetSource(mediaSource);
var display = new Multimedia.Display(Window.Instance);
_player.Display = display;
await _player.PrepareAsync();
The player state gets stuck in preparing, and the await _player.PrepareAsync() call never finishes. It is worth noting that I'm using the Tizen Samsung TV Emulator. Do I need to transcode the stream from the HDHomeRun to be playable? Are there any other measures I might be missing for the Video to play?
Ultimately, the Display property of the player wasn't being set correctly. The property that worked for me (found from investigating the JuvoPlayer code was this:
var display = new Multimedia.Display(((FormsApplication)Forms.Context).MainWindow);
_player.Display = display;
When you are to develop a Tizen .NET application, please be aware of which UI framework your project is targetted for among 3 different types: Xamarin.Forms, (pure) ElmSharp, and Tizen.NUI.
Unless your project is based on the Tizen.NUI framework, you shouldn't use Tizen.NUI.Window.Instance and types in Tizen.NUI namespace in any case. Instead, you will have to use types of ElmSharp or Xamarin.Forms.Platform.Tizen namespace for platform-specific code in your application.
Since the internal implementation of Xamarin.Forms for Tizen is based on ElmSharp, FormsApplication.MainWindow will return a ElmSharp.Window instance which can be used to instantiate a Tizen.Multimedia.Display object. That's why the code in your answer worked.
I am having some difficulty stream online radio in Android Using MvvmCross. I found the plugin Xamarin MediaManager and tried to go that route.
Here's the code:
public IMvxCommand ListenCommand => new MvxCommand(Play);
private void Play()
{
CrossMediaManager.Current.Play("http://ic2.christiannetcast.com/wayg-fm");
}
In my axml, there is a button bound to that command and pressing it outputs this in the console:
[MediaPlayer] Couldn't open http://ic2.christiannetcast.com/wayg-fm: java.io.FileNotFoundException: No content provider: http://ic2.christiannetcast.com/wayg-fm
I've tested it with several different links just to make sure that wasn't't the case. Also, I've made sure to have <uses-permission android:name="android.permission.INTERNET" /> in my AndroidManifest.xml
I've also tried using Android's MediaPlayer, but I get the exact same result.
Please let me know if there is something I am missing. I haven't found any solutions online regarding this issue. Thanks!
EDIT
I am running this on an Android emulator, not a real phone. Don't know if this makes a difference.
[MediaPlayer] Couldn't open xxx java.io.FileNotFoundException: No content provider: xxx
void setDataSource(String path):
Sets the data source (file-path or http/rtsp URL) to use.
#param path the path of the file, or the http/rtsp URL of the stream you want to play
setDataSource(Context context, Uri uri):
Sets the data source as a content Uri.
#param uri the Content URI of the data you want to play
which assumes URI to be of some form of ContentProvider
Solution:
Change your MediaPlayer SetDataSource method from:
mediaPlayer.SetDataSource(context, Android.Net.Uri.Parse(url));
To:
mediaPlayer.SetDataSource(url);
I test it on my side and it works fine:
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.Reset();
mediaPlayer.SetDataSource("https://ia800806.us.archive.org/15/items/Mp3Playlist_555/AaronNeville-CrazyLove.mp3");
mediaPlayer.Prepare();
mediaPlayer.Start();

I'm not recommending but i've used Zxing Library for Barcode/QR code scanning and that worked for me.
here's a sample how to use this library:
// create a barcode reader instance
IBarcodeReader reader = new BarcodeReader();
// load a bitmap
var barcodeBitmap = (Bitmap)Bitmap.LoadFrom("C:\\sample-barcode-image.png");
// detect and decode the barcode inside the bitmap
var result = reader.Decode(barcodeBitmap);
// do something with the result
if (result != null)
{
txtDecoderType.Text = result.BarcodeFormat.ToString();
txtDecoderContent.Text = result.Text;
}
Documentation and other demoClient is available here
Ask if you require more code. Hope that helps..!
I'm trying to do some simple DOM manipulation when a page is rendered as a PDF using ABCPdf. I followed what they document here: http://www.websupergoo.com/helppdf9net/source/5-abcpdf/xhtmloptions/2-properties/usescript.htm
But when I try something as simple as the following:
var doc = new Doc();
doc.HtmlOptions.UseScript = true;
doc.HtmlOptions.UseNoCache = true;
doc.HtmlOptions.PageCachePurge();
doc.HtmlOptions.OnLoadScript = #"var reportElms = document.getElementsByClassName(""report"");";
doc.Page = doc.AddPage();
doc.AddImageUrl(Url.Action("TestPdf", "Pdf", new { }, "http"));
I get the exception:
Unable to render HTML. Unable to apply JScript.
COM error 80020101.
Script 'var reportElms = document.getElementsByClassName("report");'.
Any thoughts as to what I'm doing wrong?
Not even the built in functions work
I'm even getting the same exception with the following script:
doc.HtmlOptions.OnLoadScript = #"
window.ABCpdf_RenderWait();
window.ABCpdf_RenderComplete();";
Btw, I'm using version 8 because that's what we have a licence for.
Edit:
I was missing the .external for the ABCpdf_RenderWait() and ABCpdf_RenderComplete() calls. It works if you reference them properly (imagine that):
doc.HtmlOptions.OnLoadScript = #"
window.external.ABCpdf_RenderWait();
window.external.ABCpdf_RenderComplete();";
Though as I mention in my answer, there are a lot of security hoops that need to be jumped through for IE also.
So I didn't actually get the IE engine to execute JavaScript the way I wanted but I was able to find a solution using the Gecko engine. The original NuGet install did not include the Gecko DLL, so I just downloaded the standalone install and added the DLLs manually.
After that everything worked exactly as expected.
I believe that the IE engine didn't work because it requires a lot of security configuration, because the FAQs spend a lot of time discussing debugging of security: http://www.websupergoo.com/support.htm#6.7
