I have ListView and i uses ion library to load images in he rows of it, When i tap on any row i take the data on the row like TextView and display it in activity using Intent

Sender Activity

// Keys
public static String TITLE = "title";
public static String ARTICLE = "article";
public static String IMG = "img";


Intent passData = new Intent(getContext(), ArticleScreen.class);
       passData.putExtra(TITLE, tv.getText());
       passData.putExtra(ARTICLE, tv2.getText());
       getContext().startActivity(passData);

Receiver Activity

Bundle extras = getIntent().getExtras();

    if (extras != null) {

        title = extras.getString(NewsAdapter.TITLE);
        article = extras.getString(NewsAdapter.ARTICLE);

    }

Now I have different ImageView in every row in the ListView and i want to display that image in the activity with the text using ion library, So i have Array of String named thumbUrl contains the urls that i want to display in the row and activity.

Ion in Sender Activity

ImageView iv = (ImageView) v.findViewById(R.id.mThumb);

    Ion.with(getContext()).load(thumbUrl[position])
            .withBitmap()
            .placeholder(R.drawable.ic_settings_black_24dp)
            .error(R.drawable.ic_info_outline_black_24dp)
            .intoImageView(iv);

So i tried to send that thumbUrl Array using Bundle and Intent like this:

Bundle b = new Bundle();
       b.putStringArray(IMG, thumbUrl);

       Intent passData = new Intent(getContext(), ArticleScreen.class);
       passData.putExtra(TITLE, tv.getText());
       passData.putExtra(ARTICLE, tv2.getText());
       passData.putExtras(b);
       getContext().startActivity(passData);

and receive it like this:

Ion in Receiver Activity

private String[] img;

Bundle extras = getIntent().getExtras();

    if (extras != null) {

        title = extras.getString(NewsAdapter.TITLE);
        article = extras.getString(NewsAdapter.ARTICLE);
        img = extras.getStringArray(NewsAdapter.IMG);

    }

    ImageView iv = (ImageView) findViewById(R.id.articleImg);

    Ion.with(this).load(Arrays.toString(img))
            .withBitmap()
            .placeholder(R.drawable.ic_settings_black_24dp)
            .error(R.drawable.ic_info_outline_black_24dp)
            .intoImageView(iv);

But it's gives me that exception

 08-20 23:51:23.841  28725-28725/com.mEmoZz.App W/Bundle﹕ Key img expected String[] but value was a java.lang.Integer.  The default value <null> was returned.

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:699)

So what to do right now?

Sorry for that messy problem but am just a beginner and that's my first time to deal with apps like that.

You should pass the url of the image related to the row being clicked. DO NOT pass the whole array:

//In the Sender:
passData.putExtra(IMG, thumbUrl[position]);

//In the Receiver
String img = extras.getString(NewsAdapter.IMG);
