    <p>So I was reading many tutorials on how to get an image preview and then save it. The usual tutorial involves using <code>SurfaceHolder</code> and <code>SurfaceView</code> with a <code>PictureCallback</code>.</p> <p>As it appears on the <a href="http://developer.android.com/reference/android/hardware/Camera.PictureCallback.html#onPictureTaken%28byte%5B%5D,%20android.hardware.Camera%29" rel="nofollow">documentation</a> this is the signature for </p> <p><code>public abstract void onPictureTaken (byte[] data, Camera camera)</code> </p> <p>Usually to save the image you can do something like</p> <pre><code>/** Handles data for jpeg picture */ PictureCallback jpegCallback = new PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { FileOutputStream outStream = null; try { // write to local sandbox file system // outStream = // CameraDemo.this.openFileOutput(String.format("%d.jpg", // System.currentTimeMillis()), 0); // Or write to sdcard outStream = new FileOutputStream(String.format( "/sdcard/%d.jpg", System.currentTimeMillis())); outStream.write(data); outStream.close(); Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { } Log.d(TAG, "onPictureTaken - jpeg"); } }; </code></pre> <p>but I'm not interested in saving a jpeg. I want to save a tiff image. Reading the documentation I've found a really general comment on <code>data</code> format:</p> <blockquote> <p>Called when image data is available after a picture is taken. The format of the data depends on the context of the callback and Camera.Parameters settings.</p> </blockquote> <p>So I clicked on <a href="http://developer.android.com/reference/android/hardware/Camera.Parameters.html" rel="nofollow">Camera.Parameters</a> but I didn't find anything useful.</p> <p>Is there a way to save the bytes as tiff? Am I doing something wrong?</p>

    1. COLook into this: http://developer.android.com/reference/android/hardware/Camera.Parameters.html#getSupportedPictureFormats() I don't think tiff is supported by default but you can always call that method to see what is available. You can find a list of available image formats here. http://developer.android.com/reference/android/graphics/ImageFormat.html

    2. COTiff is probably not supported by any camera hardware since nobody uses tiff anymore and the other formats are usually much better. Maybe you can find a library that can encode tiff files, http://www.awaresystems.be/imaging/tiff/faq.html mentions that that should exist

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
