android - setRotation(90) to take picture in portrait mode does not work on samsung devices -

-

according documentation, setrotation(90) should rotate captured jpeg picture (takepicture in landscape mode.

this works fine on htc phone, not work on samsung google nexus s , samsung galaxy s3. bug?

i know can use matrix transform rotation, wish os can more efficiently, , don't want risk over-rotating on other devices.

edit

setting camera.setdisplayorientation(90); made preview in portrait mode, did not have affect on picture taken.

further, besides setrotation, have tried set picture size - flip h w: parameters.setpicturesize(1200, 1600);. did not have affect.

solution

apparently samsung phones set exif orientation tag, rather rotating individual pixels. ariefbayu suggested, reading bitmap using bitmapfactory not support tag. code sample solution, , solution compatible using insamplesize.

i try answer in relation exif tag. did:

bitmap realimage = bitmapfactory.decodestream(stream);  exifinterface exif=new exifinterface(getrealpathfromuri(imagepath));  log.d("exif value", exif.getattribute(exifinterface.tag_orientation)); if(exif.getattribute(exifinterface.tag_orientation).equalsignorecase("6")){      realimage=imageutil.rotate(realimage, 90); }else if(exif.getattribute(exifinterface.tag_orientation).equalsignorecase("8")){     realimage=imageutil.rotate(realimage, 270); }else if(exif.getattribute(exifinterface.tag_orientation).equalsignorecase("3")){     realimage=imageutil.rotate(realimage, 180); }

the imageutil.rotate():

public static bitmap rotate(bitmap bitmap, int degree) {     int w = bitmap.getwidth();     int h = bitmap.getheight();      matrix mtx = new matrix();     mtx.postrotate(degree);      return bitmap.createbitmap(bitmap, 0, 0, w, h, mtx, true); }
