Treking Basically this is what I've done... say I have MyAppActivity which has stuff that automatically registers itself into application... events come in, application gets last accessed and I use that to start dialogs etc.
Seemed like there were cases where it was throwing exceptions about null window token even though the activity reference itself wasnt null. Ie, just simply keeping a reference around doesnt guarentee its suitable to spawn dialogs (even if it IS an activity). I also tried to have in my base callback a context we pass through... could be activity or app context and thats fine... and say I want to spawn dialog if context is a subclass of Activity... seems like that works decent... but seems like that has potential to have problems if the activity goes away before the callback returns. I guess I am frustrated... I like in IOS dev I can just create a UIAlert, and show =) I know that there are things in place on purpose (for fluid user experience, but for a lot of the stuff I build, its much lower level... rom hacking and such and I do have a legitimate excuse to be wanting to do things the way I want) Weston On Feb 15, 4:12 pm, TreKing <[email protected]> wrote: > On Wed, Feb 15, 2012 at 5:49 PM, Weston Weems <[email protected]> wrote: > > it doesnt even seem there is a decent way to > > test to see if context is > > 1) a valid ui context from which I can pop dialogs, show dialog fragments > > etc > > Don't use a base Context, use an Activity, which itself is a Context, but > one associated with UI (as opposed to, say, a Service). > > > 2) know if the reference to the instance of the activity or whatever > > actually has ties enough to spawn a dialog etc. > > That is not very clear. > > --------------------------------------------------------------------------- > ---------------------- > TreKing <http://sites.google.com/site/rezmobileapps/treking> - Chicago > transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
