    <p>look:<br> <a href="http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html" rel="nofollow">http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html</a></p> <p>1: because... Direct FROM DOC: If set to a value > 1, requests the decoder to subsample the original image, returning a smaller image to save memory. The sample size is the number of pixels in either dimension that correspond to a single pixel in the decoded bitmap. For example, inSampleSize == 4 returns an image that is 1/4 the width/height of the original, and 1/16 the number of pixels. Any value &lt;= 1 is treated the same as 1. Note: the decoder uses a final value based on powers of 2, any other value will be rounded down to the nearest power of 2. </p> <p>2:My guess is because not all the devices have the same memory available. 3: you need to calculate the sample size no just set a number... </p> <p>2,3: all devices have different cameras resolution. </p> <p>to work on this issue read this: <a href="http://developer.android.com/training/displaying-bitmaps/index.html" rel="nofollow">http://developer.android.com/training/displaying-bitmaps/index.html</a></p> <pre><code> public static Bitmap lessResolution(String filePath) { int reqHeight = 120; int reqWidth = 120; BitmapFactory.Options options = new BitmapFactory.Options(); // First decode with inJustDecodeBounds=true to check dimensions options.inJustDecodeBounds = true; BitmapFactory.decodeFile(filePath, options); // Calculate inSampleSize options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight); // Decode bitmap with inSampleSize set options.inJustDecodeBounds = false; return BitmapFactory.decodeFile(filePath, options); } private static int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) { final int height = options.outHeight; final int width = options.outWidth; int inSampleSize = 1; if (height &gt; reqHeight || width &gt; reqWidth) { // Calculate ratios of height and width to requested height and // width final int heightRatio = Math.round((float) height / (float) reqHeight); final int widthRatio = Math.round((float) width / (float) reqWidth); // Choose the smallest ratio as inSampleSize value, this will // guarantee // a final image with both dimensions larger than or equal to the // requested height and width. inSampleSize = heightRatio &lt; widthRatio ? heightRatio : widthRatio; } return inSampleSize; } </code></pre>

    1. COThanks for your reply i have updated code in my question but as you mentioned i am finding sample size using camera params but still choosing between 1 and 4 or is it better to completely go with your solution.

    2. CODepends of your needs but keep in mind that insample size is used to avoid the Out of memory when you are working with images of high resolution... sometimes the resolution of a image is too big, reduce the image resolution to 1/4 is not enough. Is not a correct way delimit the value that insample size can have..

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.
