Welcome to MAC Founded in 1891, MAC today serves 22,000 members in 600,000 square feet of recreation and event space in downtown Portland. Amenities include restaurants, banquet halls, swimming pools, exercise rooms and courts of all sizes. Opening an Application: Launch Terminal. Look for Terminal in 'Applications' → 'Utilities' →. Click Spectacle’s icon in the menu bar and select the ‘Center’ option, or just use the Option+Command+C keyboard shortcut to center it. One of these three solutions should do the trick. The app should no longer open off-screen once it’s been forced back to the center. App Center requires JavaScript. JavaScript is not enabled in your browser. Please enable JavaScript and refresh this page. From the Applications Folder The simplest, most direct way to launch an app is to open the Applications folder and click on the application you want. To find it, open the Finder from the Dock (it's usually the first icon from the left). Another way to open the Finder: Click on a blank area of the desktop.

The App Center SDK uses a modular architecture so you can use any or all of the services.

Let's get started with setting up App Center Xamarin SDK in your app to use App Center Analytics and App Center Crashes. To add App Center Distribute to you app, have a look at the documentation for App Center Distribute.

1. Prerequisites

Before you begin, make sure that the following prerequisites are met:

Your project is set up in Visual Studio 2017 or Visual Studio for Mac.
You are targeting devices running iOS 9.0 or later or Android 5.0 (API level 21) or later.
You are not using any other SDK that provides Crash Reporting functionality.

The App Center SDK for Xamarin supports the following platforms:

Xamarin.Android
Xamarin.iOS
Xamarin.Forms (iOS, Android, and UWP)

1.1 About Xamarin.Android

Choose this option if you target only Android platform. You need to create one app in the App Center portal with the Android as the OS and Xamarin as the platform.

1.2 About Xamarin.iOS

Choose this option if you target only iOS platform. You need to create one app in the App Center portal with iOS as the OS and Xamarin as the platform.

1.3 About Xamarin.Forms (iOS, Android, and UWP)

Choose this option if you want to create a cross platform app for iOS, Android and UWP devices. You need to create 3 apps in App Center – one for each OS.

You need to select Xamarin as the platform for Android and iOS applications (UWP does not have a Xamarin option).

2. Create your app in the App Center Portal to obtain the App Secret

If you have already created your app in the App Center portal, you can skip this step.

Head over to appcenter.ms.
Sign up or log in and hit the blue button on the top right corner of the portal that says Add new and select Add new app from the dropdown menu.
Enter a name and an optional description for your app.
Select the appropriate OS and platform depending on your project as described above.
Hit the button at the bottom right that says Add new app.

Once you have created an app, you can obtain its App Secret on the Settings page on the App Center Portal. At the top right hand corner of the Settings page, click on the triple vertical dots and select Copy app secret to get your App Secret.

3. Add the App Center SDK to your solution

The App Center SDK can be integrated using Visual Studio or the Package Manager Console.

Visual Studio for Mac

Open Visual Studio for Mac.
Click File > Open and choose your solution.
In the solution navigator, right click the Packages section, and choose Add NuGet packages...
Search for App Center, and select App Center Analytics and App Center Crashes.
Click Add Packages.

Visual Studio for Windows

Open Visual Studio for Windows.
Click File > Open and choose your solution.
In the solution navigator, right-click References and choose Manage NuGet Packages.
Search for App Center, and install Microsoft.AppCenter.Analytics and Microsoft.AppCenter.Crashes packages.

Package Manager Console

Open the console in Visual Studio. To do this, choose Tools > NuGet Package Manager > Package Manager Console.
If you're working in Visual Studio for Mac, make sure you have NuGet Package Management Extensions installed. For this, choose Visual Studio > Extensions, search for NuGet and install, if necessary.
Type the following command in the console:

Now that you've integrated the SDK in your application, it's time to start the SDK and make use of the App Center services.

Note

If you use the App Center SDK in a portable project (such as Xamarin.Forms), you must install the packages in each of the projects: the portable, Android, and iOS ones. To do that, you should open each sub-project and follow the corresponding steps described in Visual Studio for Mac or Visual Studio for Windows sections.

4. Start the SDK

In order to use App Center, you must opt in to the module(s) that you want to use. By default no modules are started and you will have to explicitly call each of them when starting the SDK.

4.1 Add the using statements

Add the appropriate namespaces before you get started with using our APIs.

Xamarin.iOS - Open the project's AppDelegate.cs and add the following lines below the existing using statements
Xamarin.Android - Open the project's MainActivity.cs and add the following lines below the existing using statements
Xamarin.Forms - Open the project's App.xaml.cs and add the following lines below the existing using statements

4.2 Add the `Start()` method

4.2.1 Xamarin.Android

Note

In case you are using the HockeyApp SDK for Android, make sure to initialize the HockeyApp SDK AFTER the App Center SDK.

Open the project's MainActivity.cs file and add the Start() call inside the OnCreate() method

Note

If your application has background services or multiple entry points like a broadcast receiver, exported activities or content providers, it's recommended to start AppCenter in the Application.OnCreate callback instead. If this remark applies to your application and you don't already have the callback, look at this Application.OnCreate code sample.

4.2.2 Xamarin.iOS

Note

Remember that it is not possible to have more than one active crash reporting SDK in your app. Disable the other SDKs' crash reporting functionality to make sure App Center can catch the crashes.

Open the project's AppDelegate.cs file and add the Start() call inside the FinishedLaunching() method

Note

If using Crashes, you must call this method in the UI/main thread and avoid starting background tasks until the Start method returns.The reason is that any null reference exception caught from another thread while Crashes is initializing may trigger a native crash and ignore the catch clause.Once the AppCenter.Start method returns, it is safe to try/catch null reference exceptions again.You can read more about the cause of this timing issue in the Signals and third-party crash reporters article.

4.2.3 Xamarin.Forms

To use a Xamarin.Forms application targeting iOS, Android and UWP platforms, you need to create three applications in the App Center portal - one for each platform. Creating three apps will give you three App
