HockeySDK for Windows

The official Windows SDK for the HockeyApp service. Supports .NET Framework >= 4.0 as well as Windows Phone 8.

Introduction

The HockeySDK for Windows allows users to send crash reports right from within the application. When your app crashes, a file with basic information about the environment (device type, OS version, etc.), the reason and the stacktrace of the exception is created. The next time the user starts the app, he is asked to send the crash data to the developer. If he confirms the dialog, the crash log is sent to HockeyApp and then the file deleted from the device.

Furthermore it wraps the necessary api calls for sending feedback information to the platform.

Features & Installation via Nuget

If you want to use the nuget packages make sure you have prerelease filter activated.

Windows Phone 8

Nuget PM> Install-Package HockeySDK.WP

• Automatic crash reporting (store and beta apps)
• Feedback page (store and beta apps): Let your users send you feedback messages via HockeyApp
• Automatic updates (only beta apps): Either all beta users must have developer unlocked phones or you need to either use an Enterprise Certificate to sign your beta apps. See http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj206943(v=vs.105).aspx

WP75

Deprecated but still available (no Nuget package available -> use the source)

• Crash reporting and Feedback (works for beta and store apps)

WinRT (Windows Store Apps)

Nuget PM> Install-Package HockeySDK.WinRT

• Automatic crash reporting
• Using feedback and update functionality(see below)

WPF

Nuget PM> Install-Package HockeySDK.WPF

• Automatic crash reporting
• Using feedback and update functionality(see below)

Portable lib (supports SL5, Win8, Net >= 4.0)

Nuget PM> Install-Package HockeySDK.Core

A basic API wrapper for the HockeyApp API that supports

• Handling of crashes
• Submitting of crashes to the HockeyApp server
• Checking for newest app version
• Sending feedback to the developers

Requirements

Before you integrate HockeySDK into your own app, you should add the app to HockeyApp if you haven't already. Read http://support.hockeyapp.net/kb/about-general-faq/how-to-create-a-new-app on how to do this.

Getting started with WP8

Configure the CrashHandler

1. Open your App.xaml.cs

• Search for the "App" constructor method and add the following line after InitializePhoneApplication() :

  CrashHandler.Instance.Configure(this, YOUR_APP_ID, RootFrame);

• Replace YOUR_APP_ID with the App ID of your app on HockeyApp. See http://support.hockeyapp.net/kb/about-general-faq/how-to-find-the-app-id
• Open the root page of your app (or the page in which you want to check for new crashes), for example MainPage.xaml.cs.
• Search the constructor of the class, e.g. "MainPage", and add the following line at the bottom:

  HockeyApp.CrashHandler.Instance.HandleCrashes();

  If you want to send crashes without user interaction, use this line instead:

  HockeyApp.CrashHandler.Instance.HandleCrashes(true);

  There is also an Async Version of that method if you use async in your framework.

Now every time when an unhandled exception occurs, the exception stacktrace is logged. At the next start, you should be asked to send the crash data (or crashes are sent automatically if you configured this).

Link the feedback page

Use the following line in an apropriate place (like a click-handler for a Feedback-Button)

FeedbackManager.Instance.NavigateToFeedbackUI(NavigationService);

if you don't have access to NavigationService in your ViewModels (like when using Caliburn.Micro) you should use the following URI with your navigation framework

new Uri("/HockeyApp;component/Views/FeedbackPage.xaml", UriKind.Relative)

Use automatic updates

Use the next line right after the call to HandleCrashes() to check for updates and present them to the user automatically

UpdateManager.RunUpdateCheck(Constants.HockeyAppAppId);

Getting started with WinRT

See the WPF-Section for Details. The WinRT-Implementation is very similar to the WPF-Implementation.

Getting started with WPF

Configure the CrashHandler

1. Open your App.xaml.cs and override the OnStartup-Method. If your are using frameworks like Caliburn.Micro use the caliburn-bootstrapper.
2. Before calling any methods you have to configure the sdk via HockeyApp.HockeyClientWPF.Instance.Configure(YOURAPPID, YOURAPPVERSION, USERNAME, CONTACTINFO, DESCRIPTIONHANDLER, APIBASE)

• YOURAPPID and YOURAPPVERSION are not optional
• USERNAME and CONTACTINFO is for optional submitting an logged on username and contactinfo
• DESCRIPTIONHANDLER is a lambda for submitting additional information like an event log
• The default APIBASE is https://rink.hockeyapp.net/api/2/ and can be overwritten

3. After the sdk is configured, all non handled exceptions are caught by the sdk. Exception information are written to the filesystem (%APPDATA%)
4. Crashdata is send using

   HockeyApp.HockeyClientWPF.Instance.SendCrashesNowAsync();

• The user can be asked, if the crashed should be sent using HockeyApp.HockeyClientWPF.Instance.CrashesAvailable and HockeyApp.HockeyClientWPF.Instance.CrashesAvailableCount
• Crashed can be deleted using HockeyApp.HockeyClientWPF.Instance.DeleteAllCrashes()

Use Feedback

In the WPF SDK there are no UI components for the Feedback-Informations. The SDK offers methods to load Feedbacks from the server by using feedback-tokens. Feedback-tokens must stored in the client application. Creating a new Feedback:

1. HockeyApp.HockeyClientWPF.Instance.CreateFeedbackThread() creates an new IFeedbackThread
2. feedbackThread.PostFeedbackMessageAsync(MESSAGE, EMAIL, SUBJECT, USERNAME); submits a new feedback message on the selected feedback-thread.
3. The FeedbackThread is created on the server with submitting the first feedback-message (keep that in mind when storing the feedback-token information)

Using the PCL

Without using the WPF or WP-SDKs you can use the portable library directly - e.g. when implementing an own SDK.

1. First you have to configure the portable using HockeyClient.Configure(YOURAPPID,YOURVERSION,APIBASE,USERNAME,USERCONTACTINFO,DESCRIPTION) or HockeyClient.ConfigureInternal(YOURAPPID,YOURVERSION,APIBASE,USERNAME,USERCONTACTINFO, USERAGENT, SDKNAME, SDKVERSION, DESCRIPTION);
2. Exception have to be caught in your own SDK. Using HockeyClient.Instance.CreateCrashData(EXCEPTION,CRASHLOGINFO); you can serialize the CrashData using ICrashData.Serialize(Stream outputstream);
3. When you want to post all crashes to the server, HockeyClient.Deserialize(Stream inputStream) offers you a deserializing functionality.
4. With the deserialized ICrashData you can post the crash information using ICrashData.Task SendDataAsync();

Console app

There is no special SDK for console apps, because feedback information is not used in console apps. The crashhandler has to be implemented yourself. Please find an example in Hoch.exe (HockeyUploaderConsole).
