 Not readily. Moreover, you "do not have much control" over Activity A.

Is "Activity A" a specific activity of a specific app or just any arbitrary

Re: [android-developers] how to-Start new activity with also current activity running

[Dan]

By "not readily" he means that there is no nice public API for
"what application has focus", but things that look close (e.g.
RunningAppProcessInfo importance sounds close, but requires
polling, is slow to update, and refers to scheduler time, not
what the user is doing.)   If you want to play non public API
games pre-JellyBean you could watch for ActivityManager
messages for application start (JellyBean restricts the Log
output so you need to be a system app to see it.)

The Google company line for not providing such an API seems
to range from privacy to performance.  The net result is that
if the performance monitoring tools provided (stuff under
Settings or dumpsys) don't match your needs precisely, tough
luck, you don't get to harness the app developers out there
to create something beyond what Google provides.

Unless your company has some bizarre change request process,
you'll be much happier having activity A do some IPC you can
count on.

If Activity A belongs to a different team, you should be coordinating
with them, having them fix their activity so onPause() is not
destructive (such as by moving that logic to onStop() so a
dialog-themed activity can appear and Activity A can remain visually
intact), or by negotiating some sort of broadcast Intent whereby you
can let them know that you are taking over the foreground. The
onStop() approach, with Activity B being a dialog-themed activity,
would seem to be the simplest approach given your description.

Yes, Activity A belongs to a different team. I can ask for change request 
if possible.

1) But what do you mean by 'not readily' ? is it possible to detect ?

2) I was wondering if there was another solution using TYPE_SYSTEM_DIALOG 
which I am guessing if it can be called from a Service rather than an 
Activity. But nobody replied to this post.

Re: [android-developers] how to-Start new activity with also current activity running

Ok.

So,  in Activity A's onPause, is it possible to find which activity is 
launched ? i.e., when Activity B is launched, is it possible to find in 
Activity A's onPause that Activity B is launched ?

Sorry, but onPause() is always called if some other activity takes
over the foreground.

Re: [android-developers] how to-Start new activity with also current activity running

[HK]

Justin,

The behavior I am looking for which I think not supported by Android:
Activity A is running which I do not have much control, it doesn't belong 
to me.
I start Activity B whose only purpose is to display some dialogs. When I 
start Activity B, Activity A's onPause is called and this onPause draws the 
screen blank.
So I was expecting some solution where Activity A's onPause is not called. 
I know this is not normally possible with Android's concept, so I was 
hoping if some developers in this forum has some tweaks.
thanks.

Re: [android-developers] how to-Start new activity with also current activity running

[Justin Anderson]

I have an app that has an effect similar to what you are trying to
accomplish (I think)...

If you take a look at AppSwipe! in the Google Play Store you will see that
I do not get a black background... AppSwipe! runs as an activity that has a
transparent background.

https://play.google.com/store/apps/details?id=com.magouyaware.appswipe

Is this what you are trying to implement?  If so, then it has absolutely
nothing to do with whether or not onPause() gets called on the activity in
the background.  If this is not what you are trying to do, then please
clarify...

If you start some Activity B after another Activity A, A's onPause will be
called. That is how Android works. If you don't want this behavior, then
don't start another Activity.

Yes, it set in Androidmanifiest.xml:

But this doesn't work.

i am not sure if this is what you want but but what about this:

you can use the
Dialog theme and make your
Activity appear like a dialog
box:

Or if you want the
background to be
transparent, use the
Translucent theme:

I think you mean:
popup.getWindow().setBackgroundDrawable(new 
ColorDrawable(android.graphics.Color.TRANSPARENT));

I have tried this, but it doesn't work.
thanks.

Re: [android-developers] how to-Start new activity with also current activity running

[HK]

Because, I don't want onPause to be called of the current running activity. 
This will show background black.
My activity B is started from a service and is only meant for Alert dialogs 
and nothing else. So I don't want activity A to go into onPause and show 
background black.

Sorry, I don't think this is possible... Actually I just thought of a
scenario where it might be possible.  If you make Activity B have a
trasparent (or semi-transparent) background then onPause() might not get
called.  I have not verified that is the case, but you could try it and see.

Re: [android-developers] how to-Start new activity with also current activity running

Hi Jugni,

Yes, I know. That's the reason  I am asking if its possible.

As I mentioned, I don't have control over Activity A, only B. Activity A 
doesn't belong to me. My activity is activity B.

I didn't understand 'use class file'. Can you please explain in detail ?

thanks.

As I mentioned, I don't have control over A, only B.
I don't want A's onPause called when B is started.
I didn't understand your second bullet:
  "or try to read and do about intent and apply it..."

thanks.

Hello HK,

If you know the android life cycle then you may know that when we go to
next activity then first activity should be on pause.So if you want the
alert dialog then you can also show in the same activity.So why you create
the new activity.Or if you want to handle different dialog thenuse the
class file and then just call the class file from activity so activity will
be running and alert dialog also popup.
