Every Java application has a single instance of class
Runtime that allows the application to interface with
the environment in which the application is running.
[Android.Runtime.Register("java/lang/Runtime", DoNotGenerateAcw=true)]
public class Runtime : Java.Lang.Object[<Android.Runtime.Register("java/lang/Runtime", DoNotGenerateAcw=true)>]
type Runtime = class
inherit Object- Inheritance
- Attributes
Remarks
Every Java application has a single instance of class Runtime that allows the application to interface with the environment in which the application is running. The current runtime can be obtained from the getRuntime method.
An application cannot create its own instance of this class.

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) |
| Load(String) |
Loads the native library specified by the filename argument. |
| LoadAsync(String) |
