BitmapFactory.decodeStream(...) called twice

[TannerS]

Was it intentionally, to have

BitmapFactory.decodeStream(getContentResolver().openInputStream(uri), null, opts);

called twice within the private Bitmap loadBitmapFromUri(Uri uri) method

it is used to return a Bitmap which is why it is returned such as

return BitmapFactory.decodeStream(getContentResolver().openInputStream(uri), null, opts);

but it is also called in the method without returning or assigning it to anything, was this a typo or intentionally?

Hi Tanner,

This is intentional. The first call passes an Options object with inJustDecodeBounds set to true. This causes the BitmapFactory to retrieve the dimensions without decoding the bitmap. In the following lines, these dimensions are used to compute a sampleSize to load an image that is approximately the same size as the screen. Then the second call to decodeStream decodes a bitmap with this size.
