    <p><strong>BACKGROUND</strong> Hey so I have a camera that I have implemented myself in code. This means I access and control the camera hardware and use it to save pictures. I can save the picture using the Camera.takePicture() function when the camera is <strong>running</strong>: running means Camera.startPreview();</p> <p><strong>PROBLEM</strong> My problem is that I want to be able to save the image also when the camera image is <strong>frozen</strong>: frozen is when Camera.stopPreview(); is called.When frozen I can see the image in my layout but how do I access it? Where is the image saved so that I might be able to modify it later?</p> <p>Thanks in advance!</p> <p><strong>------------------Update 1</strong></p> <pre><code> jpeg bla; public class jpeg implements PictureCallback{ public void onPictureTaken(byte[] data, Camera camera) { g_data = data; } } </code></pre> <p>This is part of my code. Here I am trying to write the data that would originally be saved to a global variable. However the value of g_data remains null and I am unable to set a breakpoint inside the onPictureTaken() call back function. </p> <p><strong>------------------Update 2</strong></p> <pre><code>FileOutputStream outStream = null; try { // generate the folder File imagesFolder = new File(Environment.getExternalStorageDirectory(), "MirrorMirror"); if( !imagesFolder.exists() ) { imagesFolder.mkdirs(); } // generate new image name SimpleDateFormat formatter = new SimpleDateFormat("HH_mm_ss"); Date now = new Date(); String fileName = "image_" + formatter.format(now) + ".jpg"; // create outstream and write data File image = new File(imagesFolder, fileName); outStream = new FileOutputStream(image); outStream.write(data); outStream.close(); Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length); } catch (FileNotFoundException e) { // &lt;10&gt; //Toast.makeText(ctx, "Exception #2", Toast.LENGTH_LONG).show(); e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally {} </code></pre> <p>I used this code previously to save the file from the camera onPictureTaken() function. The key here is the byte[] data which I need to save and save later. However like I said I just get a null when I check it in the debugger.</p>
