问题
I got this message on the developer console stating that my application had frozen because of:
ANR Broadcast of Intent { act=android.intent.action.SCREEN_OFF flg=0x40000000 }
There was no stack trace because this was raised by a pre-Froyo user. It doesn't even tell me which activity within my application caused the error - although I'd guess it was my Game activity.
This also matches my own experience that sometimes when my phone is running low on battery that my application will just freeze and has to be killed.
Is there something that I'm supposed to be doing within my activities to handle this freeze state?
I've now got some proper output from the market but I still don't know what to do with it.

Android will display the ANR dialog for a particular application when it detects one of the following conditions: • No response to an input event (e.g. key press, screen touch) within 5 seconds. • A BroadcastReceiver hasn't finished executing within 10 seconds.
