faço o download de umas imagens
ai pego essas imagens e faço uma galeria usando as imagens
tenho cerca de 8 gallerias e cada galeria com 20 imagens
tudo isso em um grid layout...
dai quando vou exibir as imagens das gallerias da falta de moria, mais se a galeria é com pouca imagens funciona perfeitamente...
mais tb se saiu de uma galeria e entro em outra da falta de memoria

segue o codigo......

public class Galeria extends Activity {
    List<String> paths;
    ArrayList<Bitmap> images;
    private String id;
    private DataBaseAdapter dbadapter;

    @Override
    public void onBackPressed() {
        // TODO Auto-generated method stub
        finish();
        super.onBackPressed();
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        getWindow().getDecorView().setSystemUiVisibility(View.STATUS_BAR_HIDDEN);

        // ActionBar actionBar = getActionBar();
        // actionBar.show();
        // actionBar.setDisplayHomeAsUpEnabled(true);
//        getActionBar().hide();

        setContentView(R.layout.activity_galeria);

        Log.i("teste", "on create ");

        Intent intent = getIntent();
        id = getIntent().getStringExtra("idacessoria"); // recebo o id da galeria para buscar as imagens
        Log.i("teste", "on create "+id);

        dbadapter = new DataBaseAdapter();
        paths = dbadapter.getImage(getApplicationContext(), Integer.parseInt(id));//faço a busca das iamgens

        Log.i("teste", "on create paths "+paths);

        images = new ArrayList<Bitmap>();
        for (String path : paths) {// em cada item do array de bitmap eu coloca o nome da imagem

            images.add(getAssetFile(path.toString()));
            Log.i("teste", "on create paths "+paths);
        }

        ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
        ImagePagerAdapter adapter = new ImagePagerAdapter();
        viewPager.setAdapter(adapter);



    }

    /**
    * recebe o nome do arquivo e
    * @param fileName nome do arquivo
    * @return imagem da galeria
    */
    public Bitmap getAssetFile(String fileName) {
        Bitmap bitmap = null;
        try {

            File filePath = getFileStreamPath(fileName);
            bitmap = BitmapFactory.decodeFile(filePath.toString());

            return bitmap;
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

        }
        return bitmap;
    }

    private class ImagePagerAdapter extends PagerAdapter {

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

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

        @Override
        public void finishUpdate(View arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void restoreState(Parcelable arg0, ClassLoader arg1) {
            // TODO Auto-generated method stub
        }
        @Override
        public Parcelable saveState() {
            // TODO Auto-generated method stub
            return null;
        }
        @Override
        public void startUpdate(View arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public Object instantiateItem(ViewGroup container, int position) {

            Context context = Galeria.this;
            ImageView imageView = new ImageView(context);
            int padding = context.getResources().getDimensionPixelSize(R.dimen.padding_zero);
            imageView.setPadding(padding, padding, padding, padding);
            imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
            imageView.setImageBitmap(images.get(position));
//            imageView.setImageBitmap(getAssetFile(paths.get(position)));

            ((ViewPager) container).addView(imageView);

            return imageView;
        }

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

        @Override
        public void destroyItem(View collection, int position, Object o) {
                   View view = (View) o;
                ((ViewPager) collection).removeView(view);
                view = null;

//                 final View view = (View)o;
//                 ((ViewPager) collection).removeView(view);
        }


    }

}
