use this..

in onActivityresult..

 @Override
 protected void onActivityResult(int requestCode, int resultcode, Intent intent)
 {
     super.onActivityResult(requestCode, resultcode, intent);
if(requestCode == 1)
     {
File out = new File(Environment.getExternalStorageDirectory(), "newImage.jpg");

         if(!out.exists())
         {
          Log.v("log", "file not found");
          Toast.makeText(getBaseContext(),

          "Error while capturing image", Toast.LENGTH_LONG)

          .show();

        return;

       }

         Log.v("log", "file "+out.getAbsolutePath());
         File f = new File(out.getAbsolutePath());

         try {

    ExifInterface exif = new ExifInterface(out.getAbsolutePath());
     orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
    //Toast.makeText(getApplicationContext(), ""+orientation, 1).show();
    Log.v("log", "ort is "+orientation);

   } catch (IOException e)
   {
    e.printStackTrace();
   }
          Bitmap photo =decodeFile(f,400,400);////after this use base64 to convet image because this function will do your file size in very normal size..so, outofMemory error not occured..


 }
}

and this is decode function..

public static Bitmap decodeFile(File f,int WIDTH,int HIGHT){
     try {
         //Decode image size
         BitmapFactory.Options o = new BitmapFactory.Options();
         o.inJustDecodeBounds = true;
         BitmapFactory.decodeStream(new FileInputStream(f),null,o);

         //The new size we want to scale to
         final int REQUIRED_WIDTH=WIDTH;
         final int REQUIRED_HIGHT=HIGHT;
         //Find the correct scale value. It should be the power of 2.
         int scale=1;
         while(o.outWidth/scale/2>=REQUIRED_WIDTH && o.outHeight/scale/2>=REQUIRED_HIGHT)
             scale*=2;

         //Decode with inSampleSize
         BitmapFactory.Options o2 = new BitmapFactory.Options();
         o2.inSampleSize=scale;
         return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
     } catch (FileNotFoundException e) {}
     return null;
 }
