Is it possible to record only part of a screen?

I want to record only part of a screen
I`ve tried this sdk to record a screen, but I was able to record only full screen of device

Screen recording can be done without requiring root (Android 5+) using the MediaProjection package. An example of a recording activity can be found here.

How to programmatically stop a screen video recorder from recording an Android app

I don't want anyone to use a screen recording app on their Android phone to VIDEO record my app's screen. I know screen capture can be prevented, but what about video?

By adding FLAG_SECURE into your Activity You can secure screen capturing functionality
getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);
write above setContenView();
from documentation
Android 5.0 lets you add screen capturing and screen sharing
capabilities to your app with the new android.media.projection APIs.
This functionality is useful, for example, if you want to enable
screen sharing in a video conferencing app.
The new createVirtualDisplay() method allows your app to capture the
contents of the main screen (the default display) into a Surface
object, which your app can then send across the network. The API only
allows capturing non-secure screen content, and not system audio. To
begin screen capturing, your app must first request the user’s
permission by launching a screen capture dialog using an Intent
obtained through the createScreenCaptureIntent() method.
and Also from this documentation says
Window flag: treat the content of the window as secure, preventing it
from appearing in screenshots or from being viewed on non-secure
displays.
NB
If you are using SurefaceView with media player then use SurfaceView.setSecure(true), then your video will be secured from any other apps.

Preventing other camera apps from using the camera when my app is using it

Will it be possible to prevent other camera app from using the camera while my app is using it, at least until the duration of my video recording is completed?
If yes, how can I achieve it?
If no, is there any event I can listen to to know if other camera app has accessed the camera?
What's happening is that the camera instance is being taken from my app and no video is being fed to the recorded file, only audio.

Getting live video on an android app from a wireless camera

I am trying to make a system wherein I need to send live video covered on an external wireless camera (not phone camera) to an android app I am going to make. The camera's I searched for only send videos to their own apps. So, is it possible in some way to design an app which will be able to take that live video? The camera is connected to the phone through Wifi. I need to process the video for some real time application, so I will need the live video only and not after it gets saved through their app. I have no prior experience in android, so any help will be appreciated. Thanks.

Above solution will surely prevent applications from capturing Video of your app

getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);
write above setContenView();
It prevents only snapshot capturing. And also prevents video capturing. But For video capturing its device specific.

Try adding this in your Activity,
getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);
