Install Update
This is technically an asynchronous function which triggers the application to update when you make use of the Flexible Update Type. During this process Google will overlay your application UI with their own showing the installation progress. Once complete, your application will restart.
You should only make this functionality available within your application once you have confirmed your Flexible Update has finished downloading by setting up the Flexible Install Listener.
NOTE: There is no success delegate, because on a successfull installation, your application will restart.
On Failure
A delegate that will be called if there is an error attempting to Install the Update. The delegate will produce an Install Error for the developer to handle appropriately.
