Constructors

AsyncTask()	Obsolete. Creates a new asynchronous task.
AsyncTask(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

Class	Returns the runtime class of this Object. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
IsCancelled	Obsolete. Returns true if this task was cancelled before it completed normally.
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
SerialExecutor	Obsolete. An Executor that executes tasks one at a time in serial order.
ThreadPoolExecutor	Obsolete. An Executor that can be used to execute tasks in parallel.
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Methods

Cancel(Boolean)	Obsolete. Attempts to cancel execution of this task.
Clone()	Creates and returns a copy of this object. (Inherited from Object)
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
DoInBackground(Object[])	Obsolete. Override this method to perform a computation on a background thread.
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
Execute(IRunnable)	Obsolete. Convenience version of #execute(Object...) for use with a simple Runnable object.
Execute(Object[])	Obsolete. Executes the task with the specified parameters.
ExecuteOnExecutor(IExecutor, Object[])	Obsolete. Executes the task with the specified parameters.
Get()	Obsolete. Waits if necessary for the computation to complete, and then retrieves its result.
Get(Int64, TimeUnit)	Obsolete. Waits if necessary for at most the given time for the computation to complete, and then retrieves its result.
GetAsync()
GetAsync(Int64, TimeUnit)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
GetStatus()	Obsolete. Returns the current status of this task.
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
Notify()	Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object)
NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
OnCancelled()	Obsolete. Applications should preferably override #onCancelled(Object).
OnCancelled(Object)	Obsolete. Runs on the UI thread after #cancel(boolean) is invoked and #doInBackground(Object[]) has finished.
OnPostExecute(Object)	Obsolete. Runs on the UI thread after #doInBackground.
OnPreExecute()	Obsolete. Runs on the UI thread before #doInBackground.
OnProgressUpdate(Object[])	Obsolete. Runs on the UI thread after #publishProgress is invoked.
PublishProgress(Object[])	Obsolete. This method can be invoked from #doInBackground to publish updates on the UI thread while the background computation is still running.
SetHandle(IntPtr, JniHandleOwnership)	Sets the Handle property. (Inherited from Object)
ToArray<T>()	(Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
UnregisterFromRuntime()	(Inherited from Object)
Wait()	Causes the current thread to wait until another thread invokes the java.lang.Object#notify() method or the java.lang.Object#notifyAll() method for this object. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until either another thread invokes the java.lang.Object#notify() method or the java.lang.Object#notifyAll() method for this object, or a specified amount of time has elapsed. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until another thread invokes the java.lang.Object#notify() method or the java.lang.Object#notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. (Inherited from Object)
