title: Android, how to reduce the size of a bitmap?
body: <p>I have an app that allows the user to change their profile image to another one that is stored on their device. For this, the app sends the selected image to a remote server. All this works well, so I do not put the code of that part so as not to complicate the question. My problem is that I want that bitmap sent to the server is reduced in size to prevent, for example, large files of five or six megabytes, which slow down the app. But it does not end well.</p>
  
  <p>This is my code for this:</p>
  
  <pre><code>if (requestCode == 1 &amp;&amp; resultCode == RESULT_OK) {
  
              Uri selectedImageUri = data.getData();
              imagepath = getPath(selectedImageUri);
              Bitmap bitmap=BitmapFactory.decodeFile(imagepath);
  
              ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream();
  
              //Resize the bitmap
              Bitmap resizedBitmap = Bitmap.createScaledBitmap(bitmap, 150, 150, false);
  
              resizedBitmap.compress(Bitmap.CompressFormat.JPEG,50,bytearrayoutputstream);
  
  
              //Round the image
              int min = Math.min(resizedBitmap.getWidth(), resizedBitmap.getHeight());
  
              Bitmap bitmapRounded = Bitmap.createBitmap(min, min, resizedBitmap.getConfig());
  
              Canvas canvas = new Canvas(bitmapRounded);
              Paint paint = new Paint();
              paint.setAntiAlias(true);
              paint.setShader(new BitmapShader(resizedBitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP));
              canvas.drawRoundRect((new RectF(0.0f, 0.0f, min, min)), min / 2, min / 2, paint);
  
              //bitmap to imageView
              avatar.setImageBitmap(bitmapRounded);
  
  }
  </code></pre>
  
  <p>I trying to reduce it in size (it does not work) and then round the image (this works fine) before adjusting it to the corresponding ImageView.</p>
  
  <p>The only thing that I can not get it to work properly is to reduce the size of the bitmap.</p>
