I have found solution of my problem there is my code :

BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[24*1024];  
options.inJustDecodeBounds = false;
options.inSampleSize=32;     
bmp1=BitmapFactory.decodeFile(filepath1,options);  
Bitmap b1=ThumbnailUtils.extractThumbnail(bmp1,30, 30);  
iv1.setImageBitmap(b);  
 if(bmp1!=null){  
   bmp1.recycle();
   }  
         bmp1=BitmapFactory.decodeFile(filepath1,options);
 Bitmap b2=ThumbnailUtils.extractThumbnail(bmp1,30, 30);  
 iv2.setImageBitmap(b2);  
if(bmp1!=null){  
 bmp1.recycle();
 }

similarly I have use it for four image view and set image without OOM Exception
