copied!<p>It looks like you only want to display a 160x160 bitmap, but on this line you are reading in the whole bitmap and then later scaling it down.</p> <pre><code>imageSelected = android.provider.MediaStore.Images.Media(cr, selectedImage); </code></pre> <p>You can avoid ever loading the whole bitmap into memory by using <a href="http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inJustDecodeBounds" rel="nofollow">inJustDecodeBounds</a>, and then you can scale it using <a href="http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inSampleSize" rel="nofollow">inSampleSize</a>.</p> <p>Here is some example code from the Android series on <a href="http://developer.android.com/training/displaying-bitmaps/load-bitmap.html" rel="nofollow">Loading Large Bitmaps Efficiently</a></p> <pre><code>public static int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) { // Raw height and width of image final int height = options.outHeight; final int width = options.outWidth; int inSampleSize = 1; if (height > reqHeight || width > reqWidth) { if (width > height) { inSampleSize = Math.round((float)height / (float)reqHeight); } else { inSampleSize = Math.round((float)width / (float)reqWidth); } } return inSampleSize; } public static Bitmap decodeSampledBitmapFromUri(Uri uri, int reqWidth, int reqHeight) { // First decode with inJustDecodeBounds=true to check dimensions final BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeStream(getContentResolver().openInputStream(uri), options); // Calculate inSampleSize options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight); // Decode bitmap with inSampleSize set options.inJustDecodeBounds = false; return BitmapFactory.decodeStream(getContentResolver().openInputStream(uri), null, options); } </code></pre> <p>Then to get your 160x160 image you would just do:</p> <pre><code>ivImageLoad.setImageBitmap(decodeSampledBitmapFromUri(selectedImage, 100, 100)); </code></pre>
