In ActivityManagerService there is mRecentTasks and mHistory. these seem to be key to how it all wokrs.
this is my understanding: mHistory is used to record the 'visual' order of activities that are revealed as the user pushes 'back'. mRecentTasks is the list of tasks. Which activity belongs to which task is recorded in mHistoryRecord. when you want to move a task around, such as to activate it by making it visible, you have to manipulate mHistory so that all of the activities belonging to tha task are moved as a block to the top of the mHistory stack. I have some questions: 1) why is mHistory a single stack? You could have made each task in mRecentTasks point to a different stack instance - its own stack of activities, and have the order of tasks in mRecentTasks define the order in which the different tasks were revealed as the user pushes back through the activities of one task into the activites of the next. I assume there is something fundamental I am missing that is the reason. 2) is the order of tasks in mRecentTasks important? cheers Steve On Feb 17, 7:47 pm, Dianne Hackborn <[email protected]> wrote: > On Mon, Feb 16, 2009 at 1:01 PM, stefoid <[email protected]> wrote: > > The imagination and innovation has to come from us, but it would be > > nice to have the tools available. > > At least something more than 'good luck' and an emoticon... > > So I've pointed you to the parts of the system where these kinds of features > would be added.
