androi studio bitmap 压缩后 图片方向异常

Android 使用 Camera2拍照后，获得 byte[] data，随后使用 BitmapFactory.decodeByteArray  压缩

导致图片方向异常

 

/*
* 避免出现方向异常
* */
public static Matrix getMatrix(byte[] data) {
		if (Build.VERSION.SDK_INT >= 24) {
				ExifInterface exif = null;
				try {
						exif = new ExifInterface(new ByteArrayInputStream(data));
				} catch (IOException e) {
						e.printStackTrace();
				}
				int orientation = ExifInterface.ORIENTATION_UNDEFINED;
				if (exif != null) {
						orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED);
				}
				Matrix matrix = new Matrix();
				switch (orientation) {
						case ExifInterface.ORIENTATION_ROTATE_90:
								matrix.postRotate(90);
								break;
						case ExifInterface.ORIENTATION_ROTATE_180:
								matrix.postRotate(180);
								break;
						case ExifInterface.ORIENTATION_ROTATE_270:
								matrix.postRotate(270);
								break;
						default:
								break;
				}
				return matrix;

				return null;

}

if (matrix != null) {
