I'm using the android.hardware.Camera class to take pictures and i'm finding that no exif data is stored in the images at all. If i use the camera application on my DROID all of the exif data is being saved.

我试过设置与设置（）和SetRotation（）的旋转，看看我是否能得到一些EXIF数据显示出来。当我认为我的笔记本电脑的图像的EXIF阅读器它告诉我的图像没有EXIF数据。

I've tried setting the rotation with Set() and SetRotation() to see if I can get some exif data to show up. When I view the images on my laptop with an exif reader it tells me the image has NO exif data.

推荐答案

所以经过一些研究，我发现我失去了EXIF信息，当我用下面的code将图像数据保存到SD卡。

So after some more research I found that I was loosing the EXIF information when i used the following code to save the image data to the SD card.

BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 0;
Bitmap myImage = BitmapFactory.decodeByteArray(imageData, 0, imageData.length);
FullFileName = sdImageMainDirectory.toString() + "/DCIM/Camera/" + getDateTime() + ".jpg";
fileOutputStream = new FileOutputStream(FullFileName);
BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream);
myImage.compress(CompressFormat.JPEG, quality, bos);
bos.flush();
bos.close();

我改变了上面的code到仅仅是这一点，现在从相机所有的EXIF数据是present。

I changed the above code to simply be this, and now all the EXIF data from the camera is present.

FileOutputStream file = new FileOutputStream(FileName);
file.write(imageData);
