Taking a picture and storing it to internal storage
<p>I'm trying to take a picture and when the user clicks the button, I want to save the picture to the internal storage. I will be testing on a tablet which does not have an sd card. I'm also new to taking pictures on android and the web has been no help with trying to find what specific code I need to write it to somewhere other than an sd card. Here is what my camera.java looks like.</p>

                // Or write to sdcard
                //outStream = new FileOutputStream(String.format("/sdcard/%d.jpg", System.currentTimeMillis()));    
                outStream.write(data);
                outStream.close();
