After taking the photo, look at the rotation angle, if there is a rotation angle, the description is rotated, and then rotated back with the rotation matrix.

Calling party:

int degree = bitmaputils.getbitmapdegree (File.getabsolutepath ()); Bitmaputils.compressbitmapforuploadlimitmaxsize (This, file, max_upload_size); Bitmaputils.rotatebitmapbydegree (file, degree);
 Public Static intgetbitmapdegree (String path) {intdegree = 0; Try {            //reads a picture from the specified path and obtains its EXIF informationExifinterface Exifinterface =Newexifinterface (path); //get rotation information for a picture            intOrientation =Exifinterface.getattributeint (Exifinterface.tag_orientation,            Exifinterface.orientation_normal); Switch(orientation) { CaseExifInterface.ORIENTATION_ROTATE_90:degree= 90;  Break;  CaseExifInterface.ORIENTATION_ROTATE_180:degree= 180;  Break;  CaseExifInterface.ORIENTATION_ROTATE_270:degree= 270;  Break; }        } Catch(IOException e) {e.printstacktrace (); }        returndegree; }     Public Static voidRotatebitmapbydegree (File file,intdegree) {        if(File = =NULL|| !file.exists () | | degree = = 0) {            return; } Bitmap Bitmap=NULL, Rotatedbitmap =NULL; Try{bitmap=Bitmapfactory.decodefile (File.getabsolutepath ()); if(Bitmap = =NULL) {                return; }            //creates a rotation matrix based on the rotation angleMatrix Matrix =NewMatrix ();            Matrix.postrotate (degree); //rotate the original image according to the rotation matrix and get a new pictureRotatedbitmap = Bitmap.createbitmap (Bitmap, 0, 0, bitmap.getwidth (), Bitmap.getheight (), Matrix,true);        Savebitmap2file (rotatedbitmap, file); } Catch(OutOfMemoryError e) {l.exception (e); } finally {            if(Bitmap! =NULL) {bitmap.recycle (); }            if(Rotatedbitmap! =NULL) {rotatedbitmap.recycle ();        } System.GC (); }    }
