I have been creating a component that will manage some data on my amazon webservice and I would like to use the amazon library on working with it but I have been encountering an error here is the error:
Fatal error: Class 'JView' not found in C:\xampp\htdocs\joomla1\administrator\components\com_amazon\views\amazon\view.html.php on line 8
here the code coming from the view:
jimport('joomla.application.component.view');
class AmazonViewAmazon extends JView{
function display()
{
$this->setLayout('table_layout');
parent::display();
}
}
It's weird cause the error will only happen when I require the sdk library from the amazon package here is the controller code I have:
jimport('joomla.application.component.controller');
class AmazonController extends JController
{
function display()
{
require_once(JPATH_COMPONENT.DS.'lib'.DS.'amazon'.DS.'sdk.class.php');
parent::display();
}
}
If I try to comment out the require_once statement from the code above the component will load successfully, is there anyone who is able to encounter the same problem I'm encountering or anyone who has knowledge about how to resolve it? any answer is highly appreciated. :)
I impacted the same problem here. Tried to fix it with namespaces which did no help, so I switched to this solution http://undesigned.org.za/2007/10/22/amazon-s3-php-class
It's pretty simple and does the trick perfectly.

I am trying to make my Xamarin Project use MVVM with Prism and DryIoc.
I mostly want to use AutoRegistration like below:
[AutoRegisterForNavigation]
...
protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
//Pages
containerRegistry.RegisterForNavigation<NavigationPage>();
//Services
containerRegistry.RegisterSingleton<ILocalDatabase, LocalDatabase>();
containerRegistry.RegisterSingleton<IUserProfileDataStore, UserProfileDataStore>();
containerRegistry.RegisterSingleton<IApplicationSettings, ApplicationSettings>();
containerRegistry.RegisterSingleton<ILogger, Logger>();
containerRegistry.RegisterSingleton<IApiService, ApiService>();
containerRegistry.RegisterSingleton<IUserSession, UserSession>();
containerRegistry.Register<IBrowser, BrowserImplementation>();
containerRegistry.Register<IConnectivity, ConnectivityImplementation();
containerRegistry.Register<IFileSystem, FileSystemImplementation>();
containerRegistry.Register<ICoreServices, CoreServices>();
}
I have also tried Manual Registration:
containerRegistry.RegisterForNavigation<LoginPage, LoginPageViewModel>();
Neither works, It hits the Login Page code behind then breaks with the following error:
Exception - High: Prism.Ioc.ContainerResolutionException:
An unexpected error occurred while resolving 'AppetiteApp.ViewModels.LoginPageViewModel' --->
DryIoc.ContainerException: code: UnableToResolveUnknownService; message: Unable to resolve
Resolution root AppetiteApp.ViewModels.LoginPageViewModel
with passed arguments [value(Prism.Navigation.ErrorReportingNavigationService)]
**System.NullReferenceException:** 'Object reference not set to an instance of an object.'
I've also tried using a Linker file setting it's build action to "linkdescription"
As for my Login Page here is the declaration
public LoginPageViewModel(ICoreServices coreServices)
: base(coreServices)
The constructor of LoginPageViewModel requires the ICoreServices argument which is registered.
The error message says that the LoginPageViewModel itself is unknown to the IoC - it means the type LoginPageViewModel is not directly registered and not found through dynamic registrations or unknown service resolvers.
I am not a user of the Xamarin Prism so I am not sure about its mechanism for registering the view models.
Btw, this part of error
Resolution root AppetiteApp.ViewModels.LoginPageViewModel
with passed arguments [value(Prism.Navigation.ErrorReportingNavigationService)]
basically means the view-model was resolved via the foollowing call resolver.Resolve(typeof(LoginPageViewModel), args: new[] { errorReportingNavigationService })
Hope it will help you or someone knowledgeable in Xamarin to track the error cause.
So Once I investigated Inside of ICoreServices I commented out each of the dependencies then discovered that IUserSession was the once causing problems then I dug into that and discovered that the dependences for IAppInfo and IVersionTracking were missing in the App.Xaml.cs registr tyepes so I added that and then it worked!
containerRegistry.Register<IAppInfo, AppInfoImplementation>();
containerRegistry.Register<IVersionTracking, VersionTrackingImplementation>();
So I'm trying to create a plugin that uses PrettyDialog (https://github.com/mjn1369/PrettyDialog) using the latest NativeScript seed.
However I've run into the following error when compiling:
Error: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
That happens using the following code, and calling show() (TypeScript):
export class PrettyAlert {
show() {
const alert = this.createAlert();
}
createAlert(width?: number) {
return new libs.mjn.prettydialog.PrettyDialog(app.android.context);
}
}
I've been looking into the error here (pure Android): You need to use a Theme.AppCompat theme (or descendant) with this activity
But none of the solutions have worked.
I figure it possible somehow, but I'm new a plugin building, and I'm sure there's some quirks I need to understand.
There are similar plugins - fancyalert / cfalert already if you are not very choosy about PrettyDialog.
NativeScript introduced support for AppCompatActivity from v5.x which seems just hit live. You should bypass this error if you upgrade to latest version.
Thanks in advance to all who wants to help...
I'm following the console commands guide that appears on cakephp 3.x cookbook. I have created the first example for trying to understand how it works
<?php
namespace App\Command;
use Cake\Console\Arguments;
use Cake\Console\Command;
use Cake\Console\ConsoleIo;
class HelloCommand extends Command
{
public function execute(Arguments $args, ConsoleIo $io)
{
$io->out('Hello world.');
}
}
I have saved that on src/Console, and when I execute as they said in the guide "bin/cake hello", everything is perfect, however, I want to be able to run the console command from the model. I have cheched by internet and I have tried some things but I'm not succesfull on that.
Thanks again!
Here's the scenario.
I created a brand new Asp.Net DNX RC2 Final project. I also added a .Net class library project to my solution (both under FX 4.6.1). The class library project is located in the src folder.
Then, I add a reference to the class library, and it can successfully restore all packages after making changes to the project.json file.
I've added a simple foo function to my class library
namespace ClassLibrary1
{
public class Class1
{
public static string Foo()
{
return "Bar";
}
}
}
and finally in my Home/Index view, I have added the following on top
<div>
#(ClassLibrary1.Class1.Foo())
</div>
The solution compiles with no errors.
You may think so far so good, let's continue.
Then, when I run the solution, the following is shows:
At runtime, my class library is not available.
I ran into a similar situation. In my case I got a RazorEngine exception in Visual Studio which at least gave me an indication of what was going on (it was something like a missing reference exception, even though the class library was added as a reference).
The only way that I could get it working (I'm hoping there is a better way), was to add the following code to my ConfigureServices method in Startup.cs:
services.Configure<RazorViewEngineOptions>(options =>
{
var previous = options.CompilationCallback;
options.CompilationCallback = (context) =>
{
previous?.Invoke(context);
context.Compilation = context.Compilation.AddReferences(MetadataReference.CreateFromFile(typeof(ClassLibrary1.Class1).Assembly.Location));
};
});
I got the idea from the following websites:
Callback on RazorViewEngineOptions
Configure RazorViewEngine
I did confirm that your example is working when I add the code mentioned above.
I am trying to create a Xamarin Java Binding to the Spotify Android SDK. The SDK is now separated into two parts, one for authentication and one for the player. The former java binding works, however, the seconds gives me an error.
The original question was asked on the Xamarin Forums.
Hi,
I am trying to create a binding project for the Spotify Android SDK.
The SDK is seperated into two .aar files. One for authentication and one for media playback (Player).
Firstly I tried having both .aar files in one Binding Project, but the Player.aar was ignored. However, moving it to its own seem to work.
Now, my issue is related to the Java Interface NativePlayerNotificationCallback which is generated to IPlayerNotificationCallback (hence the lack og Notification), but in the Player class it tried to implement: global::Com.Spotify.Android.Player.INativePlayerNotificationCallback.
I can find no other mention of INativePlayerNotificationCallback in the decompiled files. Only IPlayerNotificationCallback.
I understand that this is a bit difficult to imagine. Here are the java class files seen in JD-GUI:
The generated files are listed here:
Inside the file Com.Spotify.Sdk.Android.Player.IPlayerNotificationCallback.cs:
And the error message itself
Error CS0234: The type or namespace name INativePlayerNotificationCallback' does not exist in the namespaceCom.Spotify.Sdk.Android.Player'. Are you missing an assembly reference?
I would really appreciate any insight as to how I can get this to work. It looks to me like there are some inconsistencies in the naming of the interface, but I am not sure.
Thank you for helping out,
Fredrik
Should be fixed by adding metadata to Player binding project:
<metadata>
<attr path="/api/package[#name='com.spotify.sdk.android.player']/interface[#name='NativePlayerNotificationCallback']" name="visibility">public</attr>
</metadata>
and Player class extension (into the Additions directory):
using System.Collections;
using Java.Lang;
using Java.Util.Concurrent;
namespace Com.Spotify.Sdk.Android.Player
{
public partial class Player
{
public IList InvokeAll(ICollection tasks)
{
return null;
}
public IList InvokeAll(ICollection tasks, long timeout, TimeUnit unit)
{
return null;
}
public Object InvokeAny(ICollection tasks)
{
return null;
}
public Object InvokeAny(ICollection tasks, long timeout, TimeUnit unit)
{
return null;
}
}
}
You will probably need to implement these methods correctly by calling generic methods.
Also I had to add metadata to Auth library binding project (I found it in your old topics) and referenced Auth project from Player project as it uses some of the classes (maybe that's no necessary).
