Re: [android-developers] Re: Excute two activity at the same time
Thank you, Bob. I get very much cause of your help. I would research the windows manager service and if I have any result I would let you know. Regards 2010/3/22 Bob Kerns r...@acm.org If you're serious about doing this -- for example, you have some new device with a larger screen, and you're looking to compete with the iPad, then what you want is to ask in the android-porting group instead of here. This group is about things using the SDK, and you can't do it in the SDK. I think you're going to need two window managers, and a way of arbitrating and routing events (including from any physical buttons) to the appropriate one. And you're going to need scheduler changes. Right now, the foreground activity gets priority. You probably want to maintain a similar policy, but the definition of which activity gets priority gets a bit more complicated. This may not involve actual changes to the scheduler, but rather with how it gets informed about which activity to give priority to -- but to get a quick response to a tap on the other window, you may need to take further measures. If you sometimes use full screen, sometimes half, there's also issues about communicating to apps what their size is, managing the resources, deciding when to be full and when to be half, etc. I'd strongly suggest coordinating with the Android team on the question. It's an architectural issue and an architectural change, and you'd like to take it in a direction that is compatible with other devices and future releases. You don't want to be stuck down the road with a one-off version of the OS that can't run apps from the app store, etc. I do think it's something that needs to be done at some point, to keep up with hardware trends.

Re: [android-developers] Excute two activity at the same time
Hi Sven, you are right. I want to display two activities from different apps on the screen simultaneously. I know it can't run more than one activity at the same time, but I want to achieve this. I have some ideas: 1. Change the scale of application into smaller size. 2. Modify the framework to activate another activity from another application. However, I am not sure how much effort should I pay on the second step. Would you have some ideas to share with me? Regards Michael 2010/3/22 Sven Jacobs sven.jac...@web.de Hi Michael, you certainly can't modify the framework... I mean, of course you can check out the sources of the Android framework and modify them but then your application would only run on devices where *your* version of the framework is installed. I don't think you want that. What do you want to archive? Do you want to display two activities from different apps on the screen simultaneously? Or are the activities part of your application? If latter is the case, why don't you adjust your app so that it displays all the data you want on one activity?
