    <p>I have seen lots of tutorial and information but i could not find any single place how to use the default settings of the existing camera application into any other customized camera application. I have seen the sharpness of the image and its focus is very fine in the built-in camera application. Now i am creating my own application with my customized features but i am still unable to make it sharp and non-blurry... I dont want to use Intent technique of the camera because i have to do some image processing afterward. </p> <p>I have used zooming but strangely zoom is not properly working ...like it works in built-in camera application</p> <p>here is my surface change code </p> <pre><code> public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { Log.e(TAG, "surfaceChanged"); // XXX stopPreview() will crash if preview is not running if (mPreviewRunning) { mCamera.stopPreview(); } Camera.Parameters params = mCamera.getParameters(); List&lt;Camera.Size&gt; sizes = params.getSupportedPreviewSizes(); mFrameWidth = w; mFrameHeight = h; // selecting optimal camera preview size { double minDiff = Double.MAX_VALUE; for (Camera.Size size : sizes) { if (Math.abs(size.height - h) &lt; minDiff) { mFrameWidth = size.width; mFrameHeight = size.height; minDiff = Math.abs(size.height - h); } } } try { //params.set("rotation", 180); //params.set("orientation", "landscape"); //params.set("auto", "WHITE_BALANCE_AUTO");//WHITE_BALANCE_AUTO Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay(); if(display.getRotation() == Surface.ROTATION_0) { params.setPreviewSize(mFrameHeight, mFrameWidth); mCamera.setDisplayOrientation(90); } if(display.getRotation() == Surface.ROTATION_90) { params.setPreviewSize(mFrameWidth, mFrameHeight); } if(display.getRotation() == Surface.ROTATION_180) { params.setPreviewSize(mFrameHeight, mFrameWidth); } if(display.getRotation() == Surface.ROTATION_270) { params.setPreviewSize(mFrameWidth, mFrameHeight); mCamera.setDisplayOrientation(180); } if(params.isZoomSupported()) { Log.e(TAG, params.getZoom()+"surfaceChanged camer zoom"+params.getMinExposureCompensation()); params.setZoom(params.getMaxZoom()); params.setExposureCompensation(1); // params.setColorEffect("none"); params.setWhiteBalance(params.WHITE_BALANCE_AUTO); params.setFocusMode(params.FOCUS_MODE_AUTO); params.setSceneMode(params.SCENE_MODE_ACTION); } params.set("auto", "FOCUS_MODE_AUTO"); params.setPreviewSize(mFrameWidth,mFrameHeight); mCamera.setParameters(params); mCamera.setPreviewDisplay(holder); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } mCamera.startPreview(); mPreviewRunning = true; } </code></pre> <p>Kindly let me know how to make the camera preview exactly same as the built in application one.</p>

    1. COHave you looked at the Android Camera Application code. You can pull it for the minimum version of the OS you will support and use it as a base. Keep in mind that every OS upgrade add's capabilities, and the mfg of your device probably has support for features that may or may not exist on other devices.

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.
