onReceive (Context context, Intent intent) in B & C with two calls from A
one each to B & C from A and A with have to register a "callback reciever" (as it seems to be called by coders ) with something like registerReceiver (BroadcastReceiver receiver, IntentFilter filter) before calling sendBroadcast (Intent intent) from what ( i think - i am new at this ) the SDK is calling android app Activity which is (rather obviously) the entry for "doing something" (by the user of the device) in general, the form of what you need is often called callbacks or interfaces ~ take awhile for one to grasp that we write a code-path for the instruction pointer to follow - we are not actually "driving" the code nor does the code drive the machine = we are only describing a path this is done with callbacks and interfaces ~ to do it like your first approach it is needful to pass a ref from A to B&C so the thread there can "callback" ~ which works but correct design is to let the SKD tell us how to do it as most hardware vendors will (likely) have someone code it from there end where onLowMemory() and so on may intercede if needed as the way the coder does it may tend to load the machine when user may suddenly decide to do something else On Oct 29, 2:08 pm, John Goche <[email protected]> wrote: > Hello, > > I have come across the following scenario: I have an activity A which > needs to launch activity B to make a selection.
