I have an app that uses a set of permissions that are only available
on Samsung devices. However, this permission is not mandatory for my
app and it will still function fine without it. Given this, are there
any restrictions against me publishing the app through the main

Is it possible the Service itself to initiate disconnects for existing

Is there a way to detect focus change on any of these views? For

where the RootActivity spawned a ChildActivity in the foreground. If
the user then switches to another Task, RootActivity still cannot tell
that its current Task is going into the background.

In the implementation of my remote service's published API, is there a
way to identify which client called a given method? For example, is
there a way to obtain a unique ID or address of the caller? I already
cache an AIDL callback reference to the client, but not sure how I can
use this for identi

The documentation for sendOrderedBroadcast() describes the function as
following:
"Broadcast the given intent to all interested BroadcastReceivers,
delivering them one at a time to allow more preferred receivers to

implement the interface itself.

Whenever I invoked `sendBroadcast()` using an intent with Component
name set, it does not get properly delivered to the destination's
broadcast receiver.
As an example, assume that I have a TargetActivity that registered a

Currently, when I start ActivityB, Android pushes a blank screen that

I have an AIDL service that is intended to be used by both out-of-

common interface methods will either be invoked on the UI thread or in
a binder background thread. The logic between the two is not the
same. How do I distinguish bet
Are the UI threads for each Activity and Service in an app separate
threads, or is there actually 1 underlying UI thread per app that
processes the UI message queue for each Activity and Service?

To facilitate diagnostics while the app has been deployed, does

We have a multi-activity app that needs to communicate with a remote
service with a callback interface. Each activity needs to access the
remote service and receive callback messages from it (either directly
or indirectly). What are some good practices for designing this? Here
are some options:
-
I was playing around with the RemoteServiceBinding demo (in the API
demos), and noticed that the remote service would restart itself
(without user intervention) after the user has explicitly killed it.
How was this possible without an explict call to onBind to restart the
killed service?
