How to record screen and take screenshots, using Android API?

First step and the one which Ken White rightly suggested & which you may have already covered is the Example Code provided officially.

I have used their API earlier. I agree screenshot is pretty straight forward. But, screen recording is also under similar lines.

I will answer your questions in 3 sections and will wrap it up with a link. :)

1. Start Video Recording

private void startScreenRecord(final Intent intent) { if (DEBUG) Log.v(TAG, "startScreenRecord:sMuxer=" + sMuxer); synchronized(sSync) {  if (sMuxer == null) {   final int resultCode = intent.getIntExtra(EXTRA_RESULT_CODE, 0);   // get MediaProjection    final MediaProjection projection = mMediaProjectionManager.getMediaProjection(resultCode, intent);   if (projection != null) {    final DisplayMetrics metrics = getResources().getDisplayMetrics();    final int density = metrics.densityDpi;    if (DEBUG) Log.v(TAG, "startRecording:");    try {     sMuxer = new MediaMuxerWrapper(".mp4"); // if you record audio only, ".m4a" is also OK.      if (true) {      // for screen capturing       new MediaScreenEncoder(sMuxer, mMediaEncoderListener,       projection, metrics.widthPixels, metrics.heightPixels, density);     }     if (true) {      // for audio capturing       new MediaAudioEncoder(sMuxer, mMediaEncoderListener);     }     sMuxer.prepare();     sMuxer.startRecording();    } catch (final IOException e) {     Log.e(TAG, "startScreenRecord:", e);    }   }  } }}

2. Stop Video Recording

 private void stopScreenRecord() {  if (DEBUG) Log.v(TAG, "stopScreenRecord:sMuxer=" + sMuxer);  synchronized(sSync) {   if (sMuxer != null) {    sMuxer.stopRecording();    sMuxer = null;    // you should not wait here    }  } }

2.5. Pause and Resume Video Recording

 private void pauseScreenRecord() {  synchronized(sSync) {   if (sMuxer != null) {    sMuxer.pauseRecording();   }  } } private void resumeScreenRecord() {  synchronized(sSync) {   if (sMuxer != null) {    sMuxer.resumeRecording();   }  } }

Hope the code helps. Here is the original link to the code that I referred to and from which this implementation(Video recording) is also derived from.

3. Take screenshot Instead of Video

I think by default its easy to capture the image in bitmap format. You can still go ahead with MediaProjectionDemo example to capture screenshot.

[EDIT] : Code encrypt for screenshot

a. To create virtual display depending on device width / height

mImageReader = ImageReader.newInstance(mWidth, mHeight, PixelFormat.RGBA_8888, 2);mVirtualDisplay = sMediaProjection.createVirtualDisplay(SCREENCAP_NAME, mWidth, mHeight, mDensity, VIRTUAL_DISPLAY_FLAGS, mImageReader.getSurface(), null, mHandler);mImageReader.setOnImageAvailableListener(new ImageAvailableListener(), mHandler);

b. Then start the Screen Capture based on an intent or action-

startActivityForResult(mProjectionManager.createScreenCaptureIntent(), REQUEST_CODE);

Stop Media projection-

sMediaProjection.stop();

c. Then convert to image-

//Process the media captureimage = mImageReader.acquireLatestImage();Image.Plane[] planes = image.getPlanes();ByteBuffer buffer = planes[0].getBuffer();int pixelStride = planes[0].getPixelStride();int rowStride = planes[0].getRowStride();int rowPadding = rowStride - pixelStride * mWidth;//Create bitmapbitmap = Bitmap.createBitmap(mWidth + rowPadding / pixelStride, mHeight, Bitmap.Config.ARGB_8888);bitmap.copyPixelsFromBuffer(buffer);//Write Bitmap to file in some path on the phonefos = new FileOutputStream(STORE_DIRECTORY + "/myscreen_" + IMAGES_PRODUCED + ".png");bitmap.compress(CompressFormat.PNG, 100, fos);fos.close();

There are several implementations (full code) of Media Projection API available.Some other links that can help you in your development-

1. Video Recording with MediaProjectionManager - website

2. android-ScreenCapture - github as per android developer's observations :)

3. screenrecorder - github

4. Capture and Record Android Screen using MediaProjection APIs - website

Hope it helps :) Happy coding and screen recording!

PS: Can you please tell me the Microsoft app you are talking about? I have not used it. Would like to try it :)
