安卓：不能够得到原始照片用相机拍摄（可读取COM preSS照片只） [英] Android: Not able to get original photo captured by camera (Able to read compress photo only)
问题描述
在我的应用程序拍摄的照片通过Android摄像头，然后我想将它发送到服务器。为此，我使用客户端Socket编程。我转换拍摄的相片变成字节组（字节[]），然后将其发送到服务器。每一件事情的工作perfactally。
In my application I capture photo by android camera and then I want to send it to the server. For this I use Client Socket programming. I convert the capture photo into bytearray(byte[]) and then send it to the server. Every thing work perfactally.
问题是存在的，我不能发送原始照片给服务器。缩略图照片是由android手机sended。但是，当我用相机拍摄的照片则原始照片是存在于库中。
Problem is there I am not able to send original photo to the server. Thumbnail photo is sended by the android mobile phone. But when I capture photo by the camera then original photo is there in Gallery.
如何获取原始照片在我的应用程序中使用？
How to get this original photo to use in my application?
我的code：
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra("outputFormat",Bitmap.CompressFormat.JPEG);
cameraIntent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(cameraIntent, "Select Picture"),
CAMERA_REQUEST);
而在onActivityResult方法：
And in onActivityResult method:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
// byte[] a = (byte[]) data.getExtras().getByteArray("data"); // I also use this but not work
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(CompressFormat.JPEG, 100, bos);
byte[] bitmapdata = bos.toByteArray();
}
}
在的BitmapData 照片是有，但COM pressed照片不是原来的。 有些人说，改变质量领域的 COM preSS（比较pressFormat.JPEG，100，BOS）; 在0到100之间，但什么都不会发生。
in bitmapdata photo is there but compressed photo not the original. Some of people say that, change quality field of compress(CompressFormat.JPEG, 100, bos); in between 0 to 100 but nothing will happen.

- >> ：当这张照片是在我的电脑中的文件夹，然后我通过给路径读取照片的文件中。 EX- 文件文件=新的文件（C：\ newphoto \ image.jpg文件）; 。我可以用这个code在Android中读取原始照片，因为我知道这个名字和照片的位置。如果是的话那么什么是读取照片库的路径。这是工作，如果我给的路径为： \ DCIM \摄像头\ photoName.jpg
-- >> When The photo is in folder of my computer then I read this photo in the file by giving the path. ex- File file = new File(c:\newphoto\image.jpg); . can I use this code in android to read original photo because I know the name and location of photo. If yes then what is the path to read photo in gallery. Is this work if I give path as: \DCIM\Camera\photoName.jpg.

推荐答案
您正在使用的意图捕捉使用图像 ACTION_IMAGE_CAPTURE 。如果您在使用意向正常启动相机，然后它会返回形象在onActivityResult（位图），但是这将是缩略图的目的。
You are using the Intent to capture the image using ACTION_IMAGE_CAPTURE. If you normally starts your camera using Intent then it will return image as a bitmap in onActivityResult() but it will be for thumbnail purpose.
如果你想获得全分辨率图像从相机，那么你应该提供你所烧制启动相机活动的意图的文件。
If you want to get full resolution image from the camera then you should provide a file with the intent which you are firing to start the camera activity.
您可以像下面
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File out = Environment.getExternalStorageDirectory();
out = new File(out, imagename);
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(out));
startActivityForResult(i, CAMERA_RESULT);
下面有一个 MediaStore.EXTRA_OUTPUT 参数，这需要在其中你希望你的相机写一个图像文件的URI。
Here there is a MediaStore.EXTRA_OUTPUT parameter which takes a Uri of the file in which you want your camera to write a images.
