title: how to save photos and videos with CameraKit
body: <p>I'm making a camera app using Flurgle Camerakit, I have a camerapreview and all, I can call the cameraalistener, but what do I do after that? </p>
  
  <p>the manual says to include the following in my onclick for the shutter button </p>
  
  <pre><code>cameraView.captureImage();
  
              cameraView.setCameraListener(new CameraListener() {
                  @Override
                  public void onPictureTaken(byte[] picture) {
                      super.onPictureTaken(picture);
  
                      Bitmap result = BitmapFactory.decodeByteArray(picture, 0, picture.length);
                      ByteArrayOutputStream stream = new ByteArrayOutputStream();
                      result.compress(Bitmap.CompressFormat.PNG, 50, stream);
                      byte [] picArray = stream.toByteArray();
  
  
                  }
              });
  </code></pre>
  
  <p>when i do so, my app freezes and crashes when i click the shutter button. i also cannot figure out how to save the picture that i took into anywhere on the phone. </p>
  
  <p>the same goes for the video feature. they say to include: </p>
  
  <pre><code>cameraView.startRecordingVideo();
  
                      cameraView.setCameraListener(new CameraListener() {
                      @Override
                      public void onVideoTaken(File video) {
                          super.onVideoTaken(video);
                          // The File parameter is an MP4 file.
                      }
                  });
  
                      cameraView.startRecordingVideo();
                      cameraView.postDelayed(new Runnable() {
                          @Override
                          public void run() {
                              cameraView.stopRecordingVideo();
                          }
                      }, 2500);
  </code></pre>
  
  <p>but when i do I get the same error as before, the app freezes and crashes. </p>
  
  <p>can someone tell me how to save the created files onto the phone? </p>
  
  <p>thanks in advance! </p>
  
  <p>Edit 1: this is the logcat error when i press the video button. it turns out theres no error when i press the shutter button to take a picture, it just takes a really long time to convert the 13MP data from my phone into an array. </p>
