title: java.lang.OutOfMemoryError in opencv in android
body: <p>I am trying to use opencv in android.After so many difficulties i finally manage to run it in my device.But unfortunately it is not working.When i am trying to capture the image i am facing two problem:-
  1.The camera is showing 90 degree horizontal.
  2.When i click "capture" it is getting crashed.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>/** Handles data for raw picture */
      PictureCallback rawCallback = new PictureCallback() {
          public void onPictureTaken(byte[] data, Camera camera) {
              if (data != null) {
                  bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
                  findViewById(R.id.img).setVisibility(View.VISIBLE);
                  ((ImageView) findViewById(R.id.img)).setImageBitmap(bmp);
                  findViewById(R.id.preview).setVisibility(View.GONE);
                  if (pg != null)
                      pg.dismiss();
                  ok_button.setVisibility(View.VISIBLE);
                  click_button.setVisibility(View.GONE);
                  try_again_button.setVisibility(View.VISIBLE);
              }
          }
      };
  
      /** Handles data for jpeg picture */
      PictureCallback jpegCallback = new PictureCallback() {
          public void onPictureTaken(byte[] data, Camera camera) {
              if (data != null) {
                  bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
                  findViewById(R.id.img).setVisibility(View.VISIBLE);
                  ((ImageView) findViewById(R.id.img)).setImageBitmap(bmp);
                  findViewById(R.id.preview).setVisibility(View.GONE);
  
                  if (pg != null)
                      pg.dismiss();
                  ok_button.setVisibility(View.VISIBLE);
                  click_button.setVisibility(View.GONE);
                  try_again_button.setVisibility(View.VISIBLE);
              }
          }
      };
