Приложение для Android аварийно завершало работу при сворачивании и повороте

Поместили ли вы android:configChanges="orientation|screenSize" для активности в файл AndroidMAnifext.xml.

Пример использования PagerAdapter:

открытый класс CustomPagerAdapter расширяет PagerAdapter {

public static final String TAG = CustomPagerAdapter.class.getSimpleName();
private Context context;
private ArrayList<Object> data;
private LayoutInflater inflater;

public CustomPagerAdapter(Context context, ArrayList<Object> data)
{
    this.data = data;
    this.context = context;
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public Object instantiateItem(ViewGroup pager, final int curentItem)
{
    Log.d(TAG, "instantiateItem called for position " + curentItem);

    //Inflate
    final View localView = inflater.inflate(R.layout.home_news_slide, null);
    if(null!=localView){
        final Data currentData= (Data) this.data.get(curentItem);
        TextView title = (TextView)localView.findViewById(R.id.title_textview);
        TextView date = (TextView)localView.findViewById(R.id.date_textview);
        final ImageView imageView = (ImageView) localView.findViewById(R.id.home_slide_image);
        //Set
        title.setText(currentData.getTitle());
        date.setText(Util.dateParse((currentData.getDate())));
        imageView.setImageUrl(currentData.getArticleImage(), VolleyService.getInstance(context).getImageLoader());
        imageView.setDefaultImageResId(R.drawable.default_img);
        imageView.setErrorImageResId(R.drawable.default_img);
        //Event listener for Fragment switch
        localView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Open some activity
            }
        });
        pager.addView(localView,curentItem);
    }

    return localView;
}

@Override
public int getCount() {
    return data.size();
}

@Override
public boolean isViewFromObject(View view, Object object) {
    return view == object;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object)
{
    container.removeView((View) object);
}

}
