Android should i use lvl

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. To access this setting in Visual Studio, open the project properties in Solution Explorer and select the Android Manifest page.

In the drop-down menu under Target Android version you can select the Target Android version for your application:. 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.

To access this setting in Visual Studio for Mac, right-click the project name and select Options ; this opens the Project Options dialog. Using the drop-down menu to the right of Target Android version , you can set the Target Android version for your application:. 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. For most developers, we do not recommend setting the Target Android version to Automatic - use target framework version.

That is:. 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. For example, let's suppose that we want to use the NotificationBuilder.

SetCategory method to categorize a notification when running on Android 5. Referring to the Android version table at the beginning of this guide, we see that the build version code for Android 5. To support older versions of Android where SetCategory is not available, our code can detect the API level at runtime and conditionally call SetCategory only when the API level is greater than or equal to the Lollipop build version code:.

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.

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. For example:. 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. The following considerations apply to apps targeting Android 8. For an exhaustive list of changes introduced in Android 8. For an exhaustive list of changes introduced in Android 9.

Continue to update to API 30 by following the instructions in the previous section. As you update the target API level for your apps, consider adopting recent platform features to modernize your apps and delight your users. You should also verify any restrictions that may exist in the version of the Android Support Library that you're using.

We encourage you to update to a recent compatible Support Library in order to take advantage of the latest compatibility features and bug fixes. After you update your app's API level and features as appropriate, you should test some core use cases.

The following suggestions are not exhaustive, but aim to guide your testing process. We suggest testing:. Handles Doze with expected results and no errors. Using adb, place your test device into Doze while your app is running. Test any use cases that trigger Firebase Cloud Messaging messages. Test any use cases that use Alarms or Jobs. Eliminate any dependencies on background services. Test any use cases that use Alarms. Ensure that any critical use cases that depend on these events still work.
