Exif data TAG_ORIENTATION always 0

Question

I need to know the orientation of an image from the gallery (taken by the camera). My initial approach was to use MediaStore.Images.Media.ORIENTATION which was working for m

Answer 1

Here is the code I used onActivityResult() in my activity. The intent returned was for picking an image of the type image/*. Works well for me!

Uri imageUri = intent.getData();
String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION};
Cursor cur = managedQuery(imageUri, orientationColumn, null, null, null);
int orientation = -1;
if (cur != null && cur.moveToFirst()) {
    orientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
}  
Matrix matrix = new Matrix();
matrix.postRotate(orientation);
