You can use a lazy initialize Java Singleton, where you pass in a context in case one is needed to recreate state.
If you need to keep a context reference, make sure to call getApplicationContext and keep that instead, so you don't run into object lifetime issues and leak memory (in case that Context is an Activity or a Service, and it goes away before the process does). The stuff about not doing much in the application's onCreate I take to be more of an architectural suggestion than a real framework limitation, you can probably do as much there as in any other callback (e.g activity onCreate), subject to ANR timeouts. -- Kostya Vasilyev -- http://kmansoft.wordpress.com 06.02.2011 1:38 пользователь "AndroidDevTime" <androiddevd...@gmail.com> написал: > I have an Widget Application that also has Activities, and a heavily > used Service full of functions.
