| <p>Denotes a <code><a href="https://developer.android.com/reference/android/content/Context.html">android.content.Context</a></code> that can be used to create UI, meaning that it can provide a <code><a href="https://developer.android.com/reference/android/view/Display.html">android.view.Display</a></code> via <code><a href="https://developer.android.com/reference/android/content/Context.html#getDisplay()">android.content.Context.getDisplay</a></code> and can be used to obtain an instance of a UI-related service, such as <code><a href="https://developer.android.com/reference/android/view/WindowManager.html">android.view.WindowManager</a></code>, <code><a href="https://developer.android.com/reference/android/view/LayoutInflater.html">android.view.LayoutInflater</a></code> or <code><a href="https://developer.android.com/reference/android/app/WallpaperManager.html">android.app.WallpaperManager</a></code> via <code><a href="https://developer.android.com/reference/android/content/Context.html#getSystemService(kotlin.String)">android.content.Context.getSystemService</a></code>. A <code><a href="https://developer.android.com/reference/android/content/Context.html">android.content.Context</a></code> which is marked as <code><a href="/reference/androidx/annotation/UiContext.html">UiContext</a></code> implies that the <code><a href="https://developer.android.com/reference/android/content/Context.html">android.content.Context</a></code> is also a <code><a href="/reference/androidx/annotation/DisplayContext.html">DisplayContext</a></code>.</p> |
| <p>This kind of <code><a href="https://developer.android.com/reference/android/content/Context.html">android.content.Context</a></code> is usually an <code><a href="https://developer.android.com/reference/android/app/Activity.html">android.app.Activity</a></code> or an instance created via <code><a href="https://developer.android.com/reference/android/content/Context.html#createWindowContext(kotlin.Int, android.os.Bundle)">android.content.Context.createWindowContext</a></code>. The <code><a href="https://developer.android.com/reference/android/content/res/Configuration.html">android.content.res.Configuration</a></code> for these types of Context types is correctly adjusted to the visual bounds of your window so it can be used to get the correct values for {link android.view.WindowMetrics} and other UI related queries.</p> |
