title: Can not resolve symbol REQUEST_CODE
body: <p>I am trying to select an image from gallery using this code placed in my UploadActivity class</p>
  
  <pre><code>     @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP_MR1)
  private void selectImage(){
      Intent intent = new Intent();
      intent.setType("image/*");
      intent.setAction(Intent.ACTION_GET_CONTENT);
      if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.LOLLIPOP_MR1) {
          startActivityForResult(Intent.createChooser(intent,"Select Picture"),REQUEST_CODE);
      }
  }
  public void onActivityResult(int requestCode, int resultCode, Intent data){
      super.onActivityResult(requestCode,resultCode,data);
      if(requestCode == REQUEST_CODE &amp;&amp; resultCode == RESULT_OK &amp;&amp; data != null &amp;&amp; data.getData() != null ){
          Uri uri = data.getData();
          try {
              Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
              ImageHolder.setImageBitmap(bitmap);
          }
          catch (IOException e){
              e.printStackTrace();
          }
      }
  }
  </code></pre>
  
  <p>But it keep giving me the above error. Is there what I need to import and if yes what is it because the IDE - android studio does not show me when I click on options.
  If there is nothing to be imported, what can I edit to solve the error?</p>
  
  <p>I'll appreciate your support.</p>
