Octobre Oct BuildVersionCodes. As this table indicates, new Android versions are released frequently — sometimes more than one release per year. As a result, the universe of Android devices that might run your app includes of a wide variety of older and newer Android versions. How can you guarantee that your app will run consistently and reliably on so many different versions of Android?

Android's API levels can help you manage this problem. The API level precisely identifies the version of the API set that your app can call into; it identifies the combination of manifest elements, permissions, etc. Android's system of API levels helps Android determine whether an application is compatible with an Android system image prior to installing the application on a device.

The target API level of Android that the app is built to run on. These settings are used to ensure that the functionality needed to run the app correctly is available on the Android device at installation time. If not, the app is blocked from running on that device. For example, if the API level of an Android device is lower than the minimum API level that you specify for your app, the Android device will prevent the user from installing your app.

The following sections explain how to use the SDK Manager to prepare your development environment for the API levels you want to target, followed by detailed explanations of how to configure Target Framework, Minimum Android version, and Target Android version settings in Xamarin. La plage des choix disponibles pour la version cible de. This setting specifies what APIs your app expects to use when it runs, but it has no effect on which APIs are actually available to your app when it is installed.

As a result, changing the Target Framework setting does not change runtime behavior. La version cible du. NET Framework identifie les versions de bibliothèque auxquelles votre application est liée —. The Target Framework identifies which library versions your application is linked against — this setting determines which APIs you can use in your app.

Par exemple, si vous souhaitez utiliser la méthode NotificationBuilder. SetCategory introduite dans Android 5,0 Lollipop, vous devez définir la version cible de. For example, if you want to use the NotificationBuilder. SetCategory method that was introduced in Android 5. Si vous définissez la version cible de. Nous vous recommandons de toujours compiler avec la dernière version de Framework cible disponible. We recommend that you always compile with the latest available Target Framework version.

Doing so provides you with helpful warning messages for any deprecated APIs that might be called by your code. Using the latest Target Framework version is especially important when you use the latest support library releases — each library expects your app to be compiled at that support library's minimum API level or greater.

Visual Studio pour MacVisual Studio for Mac Pour accéder au paramètre Framework cible dans Visual Studio, ouvrez les propriétés du projet dans Explorateur de solutions puis sélectionnez la page application :To access the Target Framework setting in Visual Studio, open the project properties in Solution Explorer and select the Application page: Définissez la version cible du.

Pour accéder au paramètre Framework cible dans Visual Studio pour Mac, cliquez avec le bouton droit sur le nom du projet, puis sélectionnez options. To access the Target Framework setting in Visual Studio for Mac, right-click the project name and select Options; this opens the Project Options dialog.

Set the Target Framework by selecting an API level in the drop-down menu to the right of Target framework as shown above. Par défaut, une application ne peut être installée que sur les appareils qui correspondent au paramètre du Framework cible ou à une version ultérieure. By default, an app can only be installed on devices matching the Target Framework setting or higher; if the Minimum Android version setting is lower than the Target Framework setting, your app can also run on earlier versions of Android.

Par exemple, si vous définissez la version cible de. NET Framework sur android 7,1 nougat et que vous définissez la version Android minimale sur Android 4. For example, if you set the Target Framework to Android 7. Although your app may successfully build and install on this range of platforms, this does not guarantee that it will successfully run on all of these platforms.

For example, if your app is installed on Android 5. Therefore, your code must ensure — at runtime — that it calls only those APIs that are supported by the Android device that it is running on.

In other words, your code must include explicit runtime checks to ensure that your app uses newer APIs only on devices that are recent enough to support them. Runtime Checks for Android Versions , later in this guide, explains how to add these runtime checks to your code. Visual Studio pour MacVisual Studio for Mac Pour accéder au paramètre de version Android minimal dans Visual Studio, ouvrez les propriétés du projet dans Explorateur de solutions puis sélectionnez la page du manifeste Android.

To access the Minimum Android version in Visual Studio for Mac, right-click the project name and select Options; this opens the Project Options dialog. If you select Automatic — use target framework version, the Minimum Android version will be the same as the Target Framework setting. Android uses this setting to determine whether to enable any compatibility behaviors — this ensures that your app continues to work the way you expect.

Android uses the Target Android version setting of your app to figure out which behavior changes can be applied to your app without breaking it this is how Android provides forward compatibility.

La version cible de. The Target Framework and the Target Android version, while having very similar names, are not the same thing. Android for use at compile time, while the Target Android version communicates target API level information to Android for use at run time when the app is installed and running on a device. Visual Studio pour MacVisual Studio for Mac Pour accéder à ce paramètre dans Visual Studio, ouvrez les propriétés du projet dans Explorateur de solutions puis sélectionnez la page du manifeste Android.

To access this setting in Visual Studio, open the project properties in Solution Explorer and select the Android Manifest page. We recommend that you explicitly set the Target Android version to the latest version of Android that you use to test your app. Ideally, it should be set to the latest Android SDK version — this allows you to use new APIs prior to working through the behavior changes. Pour accéder à ce paramètre dans Visual Studio pour Mac, cliquez avec le bouton droit sur le nom du projet, puis sélectionnez options.

To access this setting in Visual Studio for Mac, right-click the project name and select Options; this opens the Project Options dialog. Ideally, it should be set to the latest available Android SDK version — this allows you to use new APIs prior to working through the behavior changes. Pour la plupart des développeurs, nous vous déconseillons de définir la version Android cible sur automatique-utiliser la version du Framework cible.

For most developers, we do not recommend setting the Target Android version to Automatic - use target framework version. NET Framework. As each new version of Android is released, the framework API is updated to provide new or replacement functionality. With few exceptions, API functionality from earlier Android versions is carried forward into newer Android versions without modifications.

But what if you also want to run your app on earlier versions of Android? If you select a Minimum Android version that is lower than your Target Framework setting, some APIs may not be available to your app at runtime.

However, your app can still run on an earlier device, but with reduced functionality. For each API that is not available on Android platforms corresponding to your Minimum Android version setting, your code must explicitly check the value of the Android.

SdkInt property to determine the API level of the platform the app is running on. Supposons, par exemple, que nous souhaitons utiliser la méthode NotificationBuilder.

For example, let's suppose that we want to use the NotificationBuilder. SetCategory method to categorize a notification when running on Android 5. En vous référant à la table de version Android au début de ce guide, nous voyons que le code de version de build pour Android 5,0 Lollipop est Android. Referring to the Android version table at the beginning of this guide, we see that the build version code for Android 5. SetCategory Notification. In this example, our app's Target Framework is set to Android 5.

Lollipop and later, this example code will call SetCategory only when it is actually available — it will not attempt to call SetCategory when the API level is 16, 17, 18, 19, or The functionality is reduced on these earlier Android versions only to the extent that notifications are not sorted properly because they are not categorized by type , yet the notifications are still published to alert the user.

Notre application fonctionne toujours, mais ses fonctionnalités sont légèrement amoindries. Our app still works, but its functionality is slightly diminished. In general, the build version check helps your code decide at runtime between doing something the new way versus the old way.

There's no fast and simple rule that explains how to reduce or modify your app's functionality when it runs on older Android versions that are lacking one or more APIs. In some cases such as in the SetCategory example above , it's sufficient to omit the API call when it's not available. However, in other cases, you may need to implement alternate functionality for when Android. SdkInt is detected to be less than the API level that your app needs to present its optimum experience.
