Hi all.
We've got a pretty large app with millions of installs. What we've
noticed is that there are always ANRs reported, even in questionable
conditions. For example, we see ANRs in the most simple of broadcast
receivers, where there are only 4 lines of code, and no networking or
file IO.
Have you used StrictMode to confirm that you are not using networking
or file I/O here? There may be file I/O under the covers in some
Android API calls you're using.
That is a good call, I will try that. I was thinking no.
Also, bear in mind that referring to classes other than the
Hi all. I was wondering what would happen in the following scenario:
Your application schedules a service or any type of pending event on
the AlarmManager. Let's say it repeats every 24 hours at noon. If an
application update is available, and the user updates the application
at 10 AM through
The AlarmManager setRepeating() methods include parameters for 1. when
it starts, and 2. how often it repeats.

I have a base group of activities. Let's call them A1, A2, and A3.
When the user switches between these activities, they are at the
bottom of the app. When they press the BACK button in either A1,
A2 , or A3, they leave the app (or task).
An easy way to visualize this is a tab activity, such as
