            <ImageView
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:id="@+id/exerciseImgB"
                android:layout_weight="1"
                android:scaleType="fitCenter"
                android:adjustViewBounds="true"
                android:paddingLeft="8dp"/>
        </LinearLayout>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:text=""
            android:id="@+id/exerciseDesc" />

        <VideoView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/exerciseVideo" />

        <ImageView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/guideImg"
            android:scaleType="fitCenter"
            android:adjustViewBounds="true"/>


    </LinearLayout>
</ScrollView>

Try this code.. This code works perfectly for me..

VideoView videoView = findViewById(R.id.videoView);
videoView.setVideoPath("http://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4");
videoView.start();
