member this.IsUiContext : bool

Property Value

Attributes

Remarks

Returns true if the context is a UI context which can access UI components such as WindowManager, android.view.LayoutInflater LayoutInflater or android.app.WallpaperManager WallpaperManager. Accessing UI components from non-UI contexts throws android.os.strictmode.Violation if android.os.StrictMode.VmPolicy.Builder#detectIncorrectContextUse() is enabled.

Examples of UI contexts are an android.app.Activity Activity, a context created from #createWindowContext(int, Bundle) or android.inputmethodservice.InputMethodService InputMethodService

Note that even if it is allowed programmatically, it is not suggested to override this method to bypass android.os.strictmode.IncorrectContextUseViolation verification.
