If You have old PC (Android in emulator with high screen resolution uses a lot of memory) or your testing phone have small screen, You can try this trick.
Rename layout folder for small device screen f.g. from layout into layout-swXXXdp and a large layout-sw600dp into layout.
Your phone with small screnn will do select xml file from renamed layout folder (for small screen).
You can to testing rotation with device en stability of fragments if an application changed orientation.
If you have old pc, you can try to make a new virtual device running on older version of Android, which uses less memory of computer.
For testing of rotation stability - application orientation changed - use on emulator Ctrl+F11, Ctrl+F12 key (Windows).

Important
Before the release of application, you have to rename layout folder to older name layout-sw600dp and layout-swXXXdp to layout.

drawText(), setColor(), setTextSize(), setTextAlign()

public class ApokusActivity extends Activity {
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(new SampleView(this));
	}

	private static class SampleView extends View {

		// CONSTRUCTOR
		public SampleView(Context context) {
			super(context);
			setFocusable(true);

		}
		@Override
		protected void onDraw(Canvas canvas) {
			Paint paint = new Paint();
			
            paint.setColor(Color.YELLOW);
            paint.setTextSize(60);
            //paint.setTextAlign(Paint.Align.CENTER);

            canvas.drawText("Hello world!", 0, 50, paint);
		}

	}
}

Problem:
You have two class with similar names HeadLinesFragment and HeadMyLinesFragment with OnHeadlineSelectedListener.
Check if call correct class in MainActivity.
For example if use HeadMyLinesFragment change implement to HeadMyLinesFragment too!

public class MainActivity extends FragmentActivity 
        implements HeadLinesFragment.OnHeadlineSelectedListener { 
// wrong implements you need correct class name 
//implements  HeadMyLinesFragment.OnHeadlineSelectedListener
//............
HeadMyLinesFragment firstFragment = new HeadMyLinesFragment(); // because in code using HeadMyLinesFragment

android:gravity="left|center_vertical" or android:gravity="right|center_vertical"

               
<Button
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:gravity="left|center_vertical"
                    android:paddingLeft="20dp"
                    android:text="My Button"
                     />

Warning: The application may be doing too much work on its main thread
Try this sorce code:

import android.os.StrictMode;

public class MyActivity extends Activity {
	static{
		StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
		StrictMode.setThreadPolicy(policy);
	}
	@Override
    public void onCreate(Bundle savedInstanceState) {
//.................. etc.
