    <p>Following code solve your problem and it may take less time on Yuv Format data because YuvImage class is provided with Android-SDK.</p> <p>You can try this,</p> <pre><code>ByteArrayOutputStream out = new ByteArrayOutputStream(); YuvImage yuvImage = new YuvImage(data, ImageFormat.NV21, width, height, null); yuvImage.compressToJpeg(new Rect(0, 0, width, height), 50, out); byte[] imageBytes = out.toByteArray(); Bitmap image = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length); iv.setImageBitmap(image); </code></pre> <p>or</p> <pre><code>void yourFunction(byte[] data, int mWidth, int mHeight) { int[] mIntArray = new int[mWidth*mHeight]; // Decode Yuv data to integer array decodeYUV420SP(mIntArray, data, mWidth, mHeight); //Initialize the bitmap, with the replaced color Bitmap bmp = Bitmap.createBitmap(mIntArray, mWidth, mHeight, Bitmap.Config.ARGB_8888); // Draw the bitmap with the replaced color iv.setImageBitmap(bmp); } static public void decodeYUV420SP(int[] rgba, byte[] yuv420sp, int width, int height) { final int frameSize = width * height; for (int j = 0, yp = 0; j &lt; height; j++) { int uvp = frameSize + (j &gt;&gt; 1) * width, u = 0, v = 0; for (int i = 0; i &lt; width; i++, yp++) { int y = (0xff &amp; ((int) yuv420sp[yp])) - 16; if (y &lt; 0) y = 0; if ((i &amp; 1) == 0) { v = (0xff &amp; yuv420sp[uvp++]) - 128; u = (0xff &amp; yuv420sp[uvp++]) - 128; } int y1192 = 1192 * y; int r = (y1192 + 1634 * v); int g = (y1192 - 833 * v - 400 * u); int b = (y1192 + 2066 * u); if (r &lt; 0) r = 0; else if (r &gt; 262143) r = 262143; if (g &lt; 0) g = 0; else if (g &gt; 262143) g = 262143; if (b &lt; 0) b = 0; else if (b &gt; 262143) b = 262143; // rgb[yp] = 0xff000000 | ((r &lt;&lt; 6) &amp; 0xff0000) | ((g &gt;&gt; 2) &amp; // 0xff00) | ((b &gt;&gt; 10) &amp; 0xff); // rgba, divide 2^10 ( &gt;&gt; 10) rgba[yp] = ((r &lt;&lt; 14) &amp; 0xff000000) | ((g &lt;&lt; 6) &amp; 0xff0000) | ((b &gt;&gt; 2) | 0xff00); } } } </code></pre>

    1. COI tried your method decodeYUV420SP() but the image that it creates is not good. It is full of yellow and green waves. I did this one and it's works: http://stackoverflow.com/questions/5272388/need-help-with-androids-nv21-format/12702836#12702836

    2. COI don't understand why the rgba[yp]=... is shifted by 8 bits. The commented out line is more correct. I get an rotated image.

    3. COis there a way of doing this with lossless compression (i.e. not JPEG)?

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.
