I am still facing Out of memory problem ,I am using this code please help me

//decodes image and scales it to reduce memory consumption
    private static Bitmap decodeFile(File f){
       try {
        //decode image size
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inSampleSize = 2;
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(new FileInputStream(f),null,o);

        //Find the correct scale value. It should be the power of 2.
        final int REQUIRED_SIZE=70;
        int width_tmp=o.outWidth, height_tmp=o.outHeight;
        int scale=1;
        while(true){
            if(width_tmp/2<REQUIRED_SIZE || height_tmp/2<REQUIRED_SIZE)
                break;
            width_tmp/=2;
            height_tmp/=2;
            scale*=2;
        }

        //decode with inSampleSize
        BitmapFactory.Options o2 = new BitmapFactory.Options();

        o2.inSampleSize=2;
        return BitmapFactory.decodeStream(new FileInputStream(f), null, null);
    } catch (FileNotFoundException e) {}
    return null;
}

Answer 1

You ran out of memory while Creating bitmap coming from ,you need to reduce the size of bitmap using

 BitmapFactory.Options option = new BitmapFactory.Options();
    option.inSampleSize = 2;


Bitmap bm = BitmapFactory.decodeFile(root.getPath() + "/" + imageName,
                            option);
                    imageView.setImageBitmap(bm);
