/**
|
|
* Displays a list of decrypted inputs.
|
|
* <p/>
|
|
* This class has a complex control flow to manage its input URIs. Each URI
|
|
* which is in mInputUris is also in exactly one of mPendingInputUris,
|
|
* mCancelledInputUris, mCurrentInputUri, or a key in mInputDataResults.
|
|
* <p/>
|
|
* Processing of URIs happens using a looping approach:
|
|
* - There is always exactly one method running which works on mCurrentInputUri
|
|
* - Processing starts in cryptoOperation(), which pops a new mCurrentInputUri
|
|
* from the list of mPendingInputUris.
|
|
* - Once a mCurrentInputUri is finished processing, it should be set to null and
|
|
* control handed back to cryptoOperation()
|
|
* - Control flow can move through asynchronous calls, and resume in callbacks
|
|
* like onActivityResult() or onPermissionRequestResult().
