aaronk Well-Known Member Licensed User Longtime User Feb 8, 2014 #1 Hello, Just wondering if anyone knows how to capture the screen of a Android device and stream it to a PC using B4A ? I have searched the Google Play store and found this: https://play.google.com/store/apps/details?id=com.mobzapp.screenstream&hl=en So it looks like its possible but I don't know how to capture the screen of the Android device ad stream it to the PC. I want to be able to it outside of the B4A as well, and looks like the above app does exactly that but I want to do the same thing using B4A. (note the above app doesn't require a rooted device) Anyone got any ideas on how to do this in B4A?

DonManfred Expert Licensed User Longtime User Feb 9, 2014 #3 i own the above app. It works till 4.3 but on 4.4.2 (KitKat) it actually does not work. The Author is working on it to get it work again also on KitKat. But i can say that this app is using a backgroundservice. I don´t know which features are inside the service Upvote 0

Click to expand... I searched based on 'screenshot' from that link but didn't really notice any that allow you to take screenshots outside of a B4A app. Do you know of any tutorials to look at that allows to take screenshots of the screen from the outside of the app, as I can't seem to find one that allow me to?

The author today released a new version which runs on 4.4.2 too on my device. Thanx for the tip @aaronk That´s a really great APP... Now i can view what happens on my device with VLC-media-player... And with VLC i can make a "screenshot" any time i need one... It doesnt matter if this is my app or not. It´s the few Euro worth in my opinion... but, i agree with you, it would be nice if we can do such things from B4A too Last edited: Feb 10, 2014 Upvote 0

May be they programatically press the button used to take screen shot (Home+volume up or plam swipe) ? Upvote 0

Erel B4X founder Staff member Licensed User Longtime User May 7, 2014 #17 It is not possible to programmatically take screenshots in Android. There are three exceptions: 1. Rooted devices. 2. With ADB (usb debug mode). 3. After ADB was connected. 2 & 3 are only useful for developers. Upvote 0
