Known indirect subclasses
AnimationDrawable, CookieSyncManager, ForkJoinWorkerThread, FutureTask<V>, HandlerThread, RenderScript.RSErrorHandler, RenderScript.RSMessageHandler, RunnableFuture<V>, RunnableScheduledFuture<V>, Thread, TimerTask
| AnimationDrawable | An object used to create frame-by-frame animations, defined by a series of Drawable objects, which can be used as a View object's background. |
| CookieSyncManager |
This class was deprecated
in API level 21.
The WebView now automatically syncs cookies as necessary.
You no longer need to create or use the CookieSyncManager.
To manually force a sync you can use the CookieManager
method CookieManager#flush which is a synchronous
replacement for sync().
|
| ForkJoinWorkerThread |
A thread managed by a ForkJoinPool, which executes
ForkJoinTasks.
|
| FutureTask<V> | A cancellable asynchronous computation. |
| HandlerThread |
A Thread that has a Looper.
|
| RenderScript.RSErrorHandler | The runtime error handler base class. |
| RenderScript.RSMessageHandler | The base class from which an application should derive in order to receive RS messages from scripts. |
| RunnableFuture<V> |
A Future that is Runnable.
|
| RunnableScheduledFuture<V> |
A ScheduledFuture that is Runnable.
|
| Thread | A thread is a thread of execution in a program. |
| TimerTask |
A task that can be scheduled for one-time or repeated execution by a
Timer.

The Runnable interface should be implemented by any
class whose instances are intended to be executed by a thread. The
class must define a method of no arguments called run.
This interface is designed to provide a common protocol for objects that
wish to execute code while they are active. For example,
Runnable is implemented by class Thread.
Being active simply means that a thread has been started and has not
yet been stopped.
In addition, Runnable provides the means for a class to be
active while not subclassing Thread. A class that implements
Runnable can run without subclassing Thread
by instantiating a Thread instance and passing itself in
as the target. In most cases, the Runnable interface should
be used if you are only planning to override the run()
method and no other Thread methods.
This is important because classes should not be subclassed
unless the programmer intends on modifying or enhancing the fundamental
behavior of the class.

run
public abstract void run ()
When an object implementing interface Runnable is used
to create a thread, starting the thread causes the object's
run method to be called in that separately executing
thread.
The general contract of the method run is that it may
take any action whatsoever.
