Need help reading the stack traces

问题

I'm getting these stack traces when running my app which crash. I get that it has to do something with "ANR keyDispatchingTimedOut". I'm new in Android development and I need some helping reading the traces.

回答1:

ANR keyDispatchingTimedOut means your activity was stuck doing something and couldn't react to the next user input.

To read a stacktrace just scan it until you see your package name, that is the bit you want to concentrate on.

I've answered this once before: ANR keyDispatchingTimedOut error

ANR Error

Activity Not Responding.

Your activity took to long to say to the Android OS 'hey i'm still alive'! (This is what the UI thread does).

http://developer.android.com/guide/practices/design/responsiveness.html

Basically if you make the UI thread do some complex task it's too busy doing your task to tell the OS that it is still 'alive'.

http://developer.android.com/resources/articles/painless-threading.html

You should move your Database select/update/delete code to another thread, then use a callback to tell the UI thread you have finished and to do something with the result.
