I've tried window.setflags(windowmanagerflags.secure, windowmanagerflags.secure) it's working for some devices if we use screen recording software but if we start recording by built in Screen Recording feature (From shortcut menu) it allows screen record. I want to completely prevent recording of my app I've searched a lot but no success yet except this answer provided in flutter i've tried in native but i didn't get the same view (SurfaceView). If this can be done in flutter then there must be a way in android too. Kindly guide.
I'm new in android developing and i want to develop an app about (android) screen sharing to multiple android device in a local network. I want to send the output of mediaprojection in real time using libstreaming library. Is it possible? How can i replace the video source of libstreaming with the mediaprojection output?
Inside the VideoStream.java file wherein the source of the media recording is set to Camera, go ahead and change it to Surface.
MediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE)
This is assuming you want the screen recording to be streamed live to another screen.
I was wondering if there was a way to record video without user input in android. I've tried to to use other code before, but it pops up the camera app which is not what I want.
You are welcome to use MediaRecorder, in conjunction with android.hardware.Camera or the android.hardware.camera2.* classes, to record a video, without the user having to do anything other than run your app.
Using an ACTION_VIDEO_CAPTURE Intent to launch a third-party video recorder will usually require that the user tap something to start recording the video.
I am making an java Application using javacv to record an video. Application can successfully record an video using webcam.
What I wanted to do is my webcam (Intex IT-305WC) having some LED lights which get on/off according to light sensitivity, I want to make that LED lights continuously on when recording get stared through my application.
Is it possible to do that?
I searched on google I found some links related to android development using PackageManager(or somethink) etc. to control mobile phones flash.
In Android/Java, Is there any code example to capture the screenshot of a computer with good frames per second programatically and create video?
I'd like a tutorial or full source code to do this. I'd like the program to work with and without the device having been "rooted".
There is app in the play store called Screencast Video Recorder that does this. But you need to ROOT the device for it to work, so I know it can be done.
What's the best way to capture android screenshot and create a video programmatically on a non-rooted device?
There is an app called Telecine that is open source that allows you to record screens - the code can be found at https://github.com/JakeWharton/Telecine. All credit is to Jake Wharton.
If you need an example, you can find one at Commonsware's github page - Mark Murphy has provided a sample app for both screen capture and screen recording using the MediaProjection APIs.
you can capture the screen via using DDMS as adb runs and has permission to the framebuffer:

hope this help .
Check the following link
https://code.google.com/p/java-remote-control/
in this project the owner has created a java remote control i.e. he has captured the images from the remote computer and transfer to server and convert it to movies with different format all you need to understand what he has done and implement the same for all your needs. you can access the full source code with SVN client from the following URL
http://java-remote-control.googlecode.com/svn/trunk/
Also you can look for the Remote class in java which provides createScreenCapture method
As of Android 4.4, there is a screen recording feature accessible via adb.
http://developer.android.com/tools/help/adb.html#screenrecord
The screenrecord command is a shell utility for recording the display of devices running Android 4.4 (API level 19) and higher. The utility records screen activity to an MPEG-4 file, which you can then download and use as part of a video presentation. This utility is useful for developers who want to create promotional or training videos without using a separate recording device.

EDIT 28/11/2014
Lollipop has been released and provides a new Screen recording API
http://developer.android.com/about/versions/android-5.0.html#UI
Screen capturing and sharing
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.
For an example of how to use the new APIs, see the MediaProjectionDemo
class in the sample project.
