ANR time change

[Dan Raaka]

Currently the Application Responding Timeout has been set at 5secs.
What is the reasoning behind that 5sec, why not 3 or 7? Is this tied
to some usability study or just the max that would be taken any code
within the platform which may run on the application UI thread ?

It's the number I picked when I implemented it, as a reasonable choice between something that is making the user wait way too long vs. not triggering in poorly behaving but not totally broken situations.

well .. If we change it to a higher value and go through adequate testing, would it be fine ?
Will this break CTS ?

[Dianne Hackborn]

No.  If you can't run the platform correctly, you need to fix that.

5 seconds is a LONG TIME. That means the UI cannot be refreshed and
that the user cannot interact with the app... for *5 seconds*. You
should really not attempt to use a higher value.

Like Romain said, a concern is that 5 seconds is a really long time to
allow the UI to be entirely unresponsive before doing anything about
it. If that value got to be changed, that should only be to make it
smaller.

Do NOT change this value, fix the app or whatever code is causing trouble.
