Does anyone knows how TeamViewer gets screen capturing?

Question

I'm looking for an way to record my Android's screen without rooting my phone. This will be on my work phone, so I'm not allowed to root it.

I recently found TeamViewer QuickSupport which lets you control an Android phone remotely, Surely someone's made an app that uses the same API that TeamViewer uses to retrieve the screen ?

I mean, TeamViewer is recording it and sending it over wifi with no trouble, so why do actual screen recording apps require root?

Does anyone knows how that tool gets screen capturing ?

Any advice?

Thanks

getting from https://stackoverflow.com/questions/3067586/how-to-capture-the-android-device-screen-content

Use the following code:

Bitmap bitmap; View v1 = MyView.getRootView();
v1.setDrawingCacheEnabled(true); bitmap =
Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false); Here MyView is the View through
which we need include in the screen. You can also get DrawingCache
from of any View this way (without getRootView()).


There is also another way.. If we having ScrollView as root view then
its better to use following code,

LayoutInflater inflater = (LayoutInflater)
this.getSystemService(LAYOUT_INFLATER_SERVICE); FrameLayout root =
(FrameLayout) inflater.inflate(R.layout.activity_main, null); //
activity_main is UI(xml) file we used in our Activity class.
FrameLayout is root view of my UI(xml) file.
root.setDrawingCacheEnabled(true); Bitmap bitmap =
getBitmapFromView(this.getWindow().findViewById(R.id.frameLayout)); //
here give id of our root layout (here its my FrameLayout's id)
