how is it possible to show an image ontop of a running activity while still being able to control the background?
in case some ppl say it is not possible, check this app out:

is there a way to open a transparent activity but still being able to control the previous activity?
ive also tried using a toast, but that is capped by a timer, and i have not been able to find a way to control it.

Is it possible to make a screenshot of a phone screen beyond the Activity background?
I want to realize an Overlay button which will make a screenshots of work of other applications on phone.
The first try in this direction was performed in this discussion Taking screenshot using OverlayService Button, but the problem wasn't solved.
I'm running into an issue and I would appreciate some guidance. I'm writing a small Android program in Android Studio that uses MediaProjection to grab a screenshot of the whole screen and then I want to pass that screenshot as a Bitmap to my System Overlay (based on the chatheads example). When the MediaProjection runs and the Imagereader creates the bitmaps, I'm passing the bitmap into a class global variable so I can pass it into my System Overlay service and display it. The problem I'm running into is if I "tab out" to a different app, my methods stop working from the MainActivity. When my app is in focus, everything works well, when a different app is focused, the system overlay contracts and expands like it should, but the screenshots are not being taken anymore. My understand is its because my app becomes "asleep" since it's not in focus. Could anyone recommend a solution? Can I momentarily awake my mainActivity so it can take a screenshot? Can I keep my activity from falling asleep on app switch? Can I bring focus to my app, take the screenshot and then switch focus to the previous app? Any other ways?

So I am building a media player app and need some direction from anyone who knows.
Since I am forced to show a notificaiton, just to control lock screen wallpaper back to android 4 I am wonder now, if a remote view has the ability to be Visibility>INVISIBLE OR GONE.
This question is mainly just to get a yes or no answer from someone who make know since I am short on time now and don't wanna chase after something that may not be possible.
I am building an Android app that uses the phone's camera feature. I know there is a way to build a custom camera view. Instead, I am choosing to use the camera app via an intent and not build my own camera view. I want to disable/make disappear the pause button while taking a video and have just the stop button. I looked up the Camera API Guide at www.developer.android.com but it doesn't talk about how I could do this. Does anyone know a way to do this?
I doesn't think that this is possible. Using Intents is just a way to tell Android "hey, I'd like to take a video (photo, see MapView, etc). Can you do it for me?". It may trigger one or MORE Apps listening to that Intent, depending on what apps the user has Installed. Usually you can only choose very basic options via Intents, i.e. take video/picture or tell the MapView at which Position it should show up. These options usually also appear inside the App during normal use. I never see a "CustomCamera-App" that hasn't a pause Button, or where one is able to deactivate it inside the menu. Therefore the chances that it is possible to set that special option tends to zero.
As Android live wallpapers are becoming more prevalent, and developers are doing more with them, a question coming up more and more is how to hide the home screen icons temporarily while the user interacts with the wallpaper.
For this to work, the icons would have to be removed temporarily – not just made invisible, since a tap on an invisible icon would still run the app.
Also, it would be ideal to have a universal solution that works across customs launchers, not just the Android stock launcher.
This question was already asked on StackOverflow, and the answer was that you cannot do this. But this is clearly not correct, as there are at least two programs on Android Market that do exactly this: Show Off (Your Live Wallpaper) and The Cleaner (Show Wallpaper)
Is there a way to hide Android home screen icons, and then later put them back in place?
You can launch an activty which backgroung will be your live walpaper, and finish the activty upon touch... Just a thought...
Edit:
1st comment answer:
Preventing the delay:
You should be more "gentle" in the onCreate() method...
Try creating the minimum as possible in the onCreate(), like, just displaying the basic background...
in the end of the onCreate function, set an alarm (i.e. by AlarmManager) to call some BroadcastReceiver/Activity after half a second or so (with AlarmManager) to set the rest of the live wallpaper graphics... that way you don't have to worry about the delay.
This would have to be a completely new launcher. This is not possible without this I don't think. Sorry. However; to be absolutely sure though you'd have to look at the Launcher2 package in the android source and look through files like Homescreen.java. I'll look into it later on 2.3.3 for you and see what I find.
Try using the zoom gesture as you would to zoom in on a web page (reverse pinch). And you guessed it, the opposite makes everything come back.
