If you do this, you must repackage the library with a utility like Jar Jar to avoid class compatibility issues with the classes provided in the runtime. Additionally, activities no longer implicitly assign initial focus in touch-mode. Instead, it is up to you to explicitly request initial focus, if desired.

CSS Color Module Level 4 has been supported by Chrome since release 52, but WebView currently disables the feature because existing Android applications were found to contain 32 bit hex colors in the Android ordering ARGB , which would cause rendering errors.

For example, the color 80ff is currently rendered in WebView as opaque light red ff for apps targeting API levels 27 or lower. The leading component which would be interpreted by Android as the alpha component is currently ignored. Using the file contents to infer MIME types can be a source of security bugs, and this is not generally permitted by modern browsers.

If a file has a recognized file extension such as. If a file has no extension or an unrecognized one, the MIME type will be plain text. Android 9 properly handles the case where a document's root element is the scrolling element.

On earlier versions, scrolling position was set on the body element, and the root element had zero scroll values. Android 9 enables the standards-compliant behaviour where the scrolling element is the root element.

Furthermore, directly accessing document. To access viewport scroll values, use document. Prior to Android 9, notifications from suspended apps were canceled. 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.

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. The Target Framework identifies which library versions your application is linked against — this setting determines which APIs you can use in your app. For example, if you want to use the NotificationBuilder.

SetCategory method that was introduced in Android 5. 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.

To access the Target Framework setting in Visual Studio, open the project properties in Solution Explorer and select the Application page:. 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.

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.

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.

In the drop-down menu under Minimum Android version you can select the Minimum Android version for your application:. 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. Using the drop-down menu to the right of Minimum Android version , you can set the Minimum Android version for your application:. 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.

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. Android 6. Revision 2 November Fixed bugs in the layout rendering library used by Android Studio.
