    <p>Perhaps this link can help you.</p> <p><a href="http://adblogcat.com/a-camera-preview-with-a-bounding-box-like-google-goggles/" rel="nofollow">http://adblogcat.com/a-camera-preview-with-a-bounding-box-like-google-goggles/</a></p> <p>Here is the onSurfaceChange method which sets the right orientation</p> <pre><code>public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { //Log.i(TAG, "Preview: surfaceChanged() - size now " + w + "x" + h); // Now that the size is known, set up the camera parameters and begin // the preview. try { mParameters = mCamera.getParameters(); mParameters.set("orientation","landscape"); for (Integer i : mParameters.getSupportedPreviewFormats()) { //Log.i(TAG, "supported preview format: " + i); } List&lt;Size&gt; sizes = mParameters.getSupportedPreviewSizes(); for (Size size : sizes) { //Log.i(TAG, "supported preview size: " + size.width + "x" + size.height); } mCamera.setParameters(mParameters); // apply the changes } catch (Exception e) { // older phone - doesn't support these calls } //updateBufferSize(); // then use them to calculate Size p = mCamera.getParameters().getPreviewSize(); //Log.i(TAG, "Preview: checking it was set: " + p.width + "x" + p.height); // DEBUG mCamera.startPreview(); } public Parameters getCameraParameters(){ return mCamera.getParameters(); } </code></pre> <p>The article sets the parameters to landscape. I see you do not have this in your code.</p> <p>Also, for saving images I see two methods:</p> <pre><code>private boolean savePhoto(Bitmap bm) { FileOutputStream image = null; try { image = new FileOutputStream(mLocation); } catch (FileNotFoundException e) { e.printStackTrace(); } bm.compress(CompressFormat.JPEG, 100, image); if (bm != null) { int h = bm.getHeight(); int w = bm.getWidth(); //Log.i(TAG, "savePhoto(): Bitmap WxH is " + w + "x" + h); } else { //Log.i(TAG, "savePhoto(): Bitmap is null.."); return false; } return true; </code></pre> <p>}</p> <p>and</p> <pre><code>public Bitmap getPic(int x, int y, int width, int height) { System.gc(); Bitmap b = null; Size s = mParameters.getPreviewSize(); YuvImage yuvimage = new YuvImage(mBuffer, ImageFormat.NV21, s.width, s.height, null); ByteArrayOutputStream outStream = new ByteArrayOutputStream(); yuvimage.compressToJpeg(new Rect(x, y, width, height), 100, outStream); // make JPG b = BitmapFactory.decodeByteArray(outStream.toByteArray(), 0, outStream.size()); if (b != null) { //Log.i(TAG, "getPic() WxH:" + b.getWidth() + "x" + b.getHeight()); } else { //Log.i(TAG, "getPic(): Bitmap is null.."); } yuvimage = null; outStream = null; System.gc(); return b; </code></pre> <p>}</p> <p>And you need to use android 2.2 </p>

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.
