- Method Detail
  - addDoneListener
```
void addDoneListener(java.lang.Runnable listener)
```
    Adds a listener to run on successful or unsuccessful completion of the asynchronous computation. The listener will run immediately if the computation is already complete when this method is called.
    Adding this listener on the UI thread will cause it to be invoked on the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.
    
    Parameters:
    
    listener - a Runnable to run when the computation is done
    
    Throws:
    
    java.lang.IllegalArgumentException - if listener is null

  - removeDoneListener
```
boolean removeDoneListener(java.lang.Runnable listener)
```
    Removes a done listener so that it will not be called when the computation completes.
    
    Parameters:
    
    listener - the listener to be removed
    
    Returns:
    
    true if the listener was removed, otherwise false
