Is there an app available that would let me modify my phone settings by application? To be specific, there are certain apps where I don't want the default screen timeout to occur. I'm on Gingerbread.
Use Llama. This is a free automation app like Tasker, and it has the ability to modify the screen timeout.
Create a new Event. Add the condition
OR (match any). Then add a condition for each
Active application that you want to keep the screen active.
Click the back button, then add the Action to change the
Screen Timeout to never.
You then have to create a second Event that does the opposite. You create the
OR (match any) condition, but this time select
Active application and change the Status option to
App stopped or in background, and again do this for each app you did in the first event. Set the
Screen Timeout action to whatever timeout value you want normally.
