Full screen videoview without stretching the video

Like this you can set the properties of the video by yourself.

Use a SurfaceView (gives you more control on the view), set it to fill_parent to match the whole screen

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     
              android:orientation="vertical" 
              android:layout_width="match_parent"
              android:layout_height="fill_parent">

    <SurfaceView
        android:id="@+id/surfaceViewFrame"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center" >
    </SurfaceView>
</Linearlayout>

then on your java code get the surface view and add your media player to it

surfaceViewFrame = (SurfaceView) findViewById(R.id.surfaceViewFrame);
player = new MediaPlayer();
player.setDisplay(holder);

set on your media player a onPreparedListener and manually calculate the desired size of the video, to fill the screen in the desired proportion avoiding stretching the video!

player.setOnPreparedListener(new OnPreparedListener() {

        @Override
        public void onPrepared(MediaPlayer mp) {
                    // Adjust the size of the video
    // so it fits on the screen
    int videoWidth = player.getVideoWidth();
    int videoHeight = player.getVideoHeight();
    float videoProportion = (float) videoWidth / (float) videoHeight;       
    int screenWidth = getWindowManager().getDefaultDisplay().getWidth();
    int screenHeight = getWindowManager().getDefaultDisplay().getHeight();
    float screenProportion = (float) screenWidth / (float) screenHeight;
    android.view.ViewGroup.LayoutParams lp = surfaceViewFrame.getLayoutParams();

    if (videoProportion > screenProportion) {
        lp.width = screenWidth;
        lp.height = (int) ((float) screenWidth / videoProportion);
    } else {
        lp.width = (int) (videoProportion * (float) screenHeight);
        lp.height = screenHeight;
    }
    surfaceViewFrame.setLayoutParams(lp);

    if (!player.isPlaying()) {
        player.start();         
    }

        }
    });

I modified this from a tutorial for video streaming that I followed some time ago, can’t find it right now to reference it, if someone does please add the link to the answer!

Hope it helps!

EDIT

Ok, so, if you want the video to occupy the whole screen and you don’t want it to stretch you will end up with black stripes in the sides. In the code I posted we are finding out what is bigger, the video or the phone screen and fitting it the best way we can.

There you have my complete activity, streaming a video from a link. It’s 100% functional. I can’t tell you how to play a video from your own device because I don’t know that. I’m sure you will find it in the documentation here or here.
