Hi Guys, Thanks for your inputs. I have one more question. Before I ask, here is in brief, about what I'm doing. I'm working on a research project in a university and we are trying to find out the mobile users' context information. For this, we need to sense the users' environment. So, the basic working of the service is as follows:
- Initialise on start : register call backs using Intent filters, SensorManager and other System services - The main thread sleeps for about 15 mins, wakes up collects info from diff. classes and sends to a server. (i'm using the Java Timer class to do this) Now, my question is : Will using the timer class, have the same effect as using the AlarmManager ? or will it consume more resources. Also, it would be great if someone can suggest better way of achieving what I'm doing. -- Cheers, ~Tejas On Thu, Jun 10, 2010 at 5:46 PM, Dianne Hackborn <hack...@android.com>wrote: > Also note we are getting increasingly hard-core on such services.
