Solve Samsung phone photos after photo rotation.

Recent projects in the face of a Samsung phone photos, the picture will automatically rotate, should be the function of the Samsung internal system, and then need to do not let him rotate, found the method.

The principle is to get to the picture, judge its rotation angle, and then rotate back accordingly.

In the return result of the photo, get the path to the picture.

Path = FilePath + fileName; Path is the route returned by the photo
File File = new file (path);
int degree = Readpicturedegree (File.getabsolutepath ());
Bitmap smallbitmap=fileutils.compresssize (Path, 800, 800);
Smallbitmap = Rotaingimageview (degree, smallbitmap);
Saveallpath = Fileutils.savebitmap (Smallbitmap, System.currenttimemillis () + (Math.random () * 10000) + ". png");// Mass compression and storage of path
Imageitem Takephoto = new Imageitem ();
Takephoto.setbitmap (SMALLBITMAP);
Takephoto.setimagepath (Saveallpath);
Bimp.tempSelectBitmap.add (Takephoto);
