                + File.separator + "MYPICS" + File.separator);
        private File[] fileName = root.listFiles();
        int count=fileName.length;
        public ImageAdapter(Context c) {

    public long getItemId(int position) {
        return 0;
    }

    // create a new ImageView for each item referenced by the Adapter
    public View getView(int position, View convertView, ViewGroup parent) {

            Uri uri = Uri.fromFile(fileName[position]);

        ImageView imageView;
        if (convertView == null) {  // if it's not recycled, initialize some attributes
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(8, 8, 8, 8);
        } else {
            imageView = (ImageView) convertView;
        }

what you have tried before asking question ? search in stackoverflow... — Samir Mangroliya, May 16 '12 at 11:06
Before this i do it with BitmapFactory but nothing works fine for me — Sachin Gurnani, May 16 '12 at 11:10
Load Full Image with out any Memory Management you will sure get OOM Error ,Please Refer this site [http://developer.android.com/training/displaying-bitmaps/index.html](Load Bitmaps ) — Herry, May 16 '12 at 11:11

If it's about image size use this code snippet `BitmapFactory.Options bitmapFactoryOptions = new BitmapFactory.Options(); bitmapFactoryOptions.inSampleSize = 2; bitmap = BitmapFactory.decodeFile(imagePath, bitmapFactoryOptions);` — AnujAroshA, May 16 '12 at 11:29
@saurabhtrivedi File sdImageMainDirectory = new File(path,"image.jpg"); Uri imgUri = Uri.fromFile(sdImageMainDirectory); Intent intent = new Intent( android.provider.MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imgUri); startActivityForResult(intent, 0); start camera with this intent image is stored in your path specified imgUri path — Sachin Gurnani, Oct 15 '12 at 18:59

add this to your manifest for listview activity

android:configChanges="orientation|keyboardHidden"

if this not helps then add this piece of code for your image file to sample the bitmap

private Bitmap decodeFile(File f){
            FileOutputStream os = null;
            try {
                //Decode image size
                BitmapFactory.Options o = new BitmapFactory.Options();
                o.inJustDecodeBounds = true;

                FileInputStream fis = new FileInputStream(f);
                BitmapFactory.decodeStream(fis, null, o);
                fis.close();

                int scale = 1;
                if (o.outHeight > IMAGE_MAX_SIZE || o.outWidth > IMAGE_MAX_SIZE) {
                    scale = (int)Math.pow(2, (int) Math.round(Math.log(IMAGE_MAX_SIZE / (double) Math.max(o.outHeight, o.outWidth)) / Math.log(0.5)));
                }

                //Decode with inSampleSize
                BitmapFactory.Options o2 = new BitmapFactory.Options();
                o2.inSampleSize = scale;
                fis = new FileInputStream(f);
                try {

                b = BitmapFactory.decodeStream(fis, null, o2);

                } catch (OutOfMemoryError e) {
                    Log.d("hai","filename"+f);
                    System.gc();
                }
                fis.close();
            } catch (IOException e) {
            }
            return b;
        }

Load lot many images causes the app to run out of memory and force closes.I think this is what happening to your application.the memory issue is a complex issue android while developing an application.this can be solved by manually clearing the unused bitmaps and by using the garbage collector.

Try using System.gc();

Try recycling the bitmap using

Bitmap.recycle();

Make all the unused bitmap null.

Deallocate all the unused memory.

This all will help you a lot and also go through this link.Use memory analyzer it will help you spot out the Deallocated memory>try this link

if the image size is bigg.then there will be a chance for oom exception.so scale down the bitmap is a simple way.check my answer — Jackson Chengalai, May 16 '12 at 11:34
File[] files = root.listFiles();for (int i = 0; i < fileNames.length; i++) { Uri uri = Uri.fromFile(files[i]); String path="/mnt/sdcard/MYPICS/MyPic"+i+".png"; /*BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 8; Bitmap yourSelectedImage = BitmapFactory.decodeFile(path);*/ Bitmap bm=decodeFile(files[i]); imageView.setImageBitmap(bm); } — Sachin Gurnani, May 16 '12 at 11:38
but it display same image 4 time and i have 6 images in my folder — Sachin Gurnani, May 16 '12 at 11:46
now ur imageview replacing each other.create a imageview array and save each image to that imageview[i] and in your getview add set your imageview array like imageview[position] — Jackson Chengalai, May 16 '12 at 11:53

He is running into out of memory error. This solution will not work. He has to work on solving Out Of memory – Andro Selva May 16 '12 at 11:19
