Handling Rotation in Android

I run a webservice get the data I want and display them in another activity. So far everything is running smoothly. And now ROTATION!:). This is what I am doing. I use the onSaveInstanceState(...) method to save the values I want in key/values pairs. After that I use the onRestoreInstanceState(...) method to read the stored values. This is my code.

public class Extras extends AppCompatActivity {
TextView textView;
TextView articleTextView;
String image;
String title;
String article;
ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_clubnews_extra);

    textView = (TextView)findViewById(R.id.textView2);
    articleTextView = (TextView)findViewById(R.id.articleTextView);

    imageView = (ImageView)findViewById(R.id.imageNews);

    Intent i = getIntent();

    title = i.getStringExtra("title");
    article = i.getStringExtra("article");
    image = i.getStringExtra("image");

    textView.setText(Html.fromHtml(title));
    articleTextView.setText(Html.fromHtml(article));

    Picasso.with(this).load(image).into(imageView);



}

@Override
public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) {
    super.onSaveInstanceState(outState, outPersistentState);

    outState.putString("title",title);
    outState.putString("article",article);
    outState.putString("image",image);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);

    savedInstanceState.getString("title");
    savedInstanceState.getString("article");
    savedInstanceState.getString("image");
 }
}

When I am putting breakpoint inside the onSaveInstanceState I see nothing when I rotate the phone/emulator. That makes me thing that the values are not stored.

Please advice.

Thanks.

You're overriding the wrong method.

Use 

public void onSaveInstanceState(Bundle outState)

Instead of,

public void onSaveInstanceState(Bundle outState, 
                            PersistableBundle outPersistentState)
