图片您可以在纵向模式将被保存在的景观。但在横向模式拍摄的图像被正确保存。

私有类SaveImageTask扩展的AsyncTask {

解决方案

一些Android摄像头的硬件将创建横向纵向图像，与JPEG文件，表明图像浏览器应旋转图像的EXIF头。

一些Android摄像头硬件会产生纵向图像人像。

还有就是你真的可以做这个没什么。欢迎您扫描所产生的JPEG的EXIF头和自己旋转图像，但这是缓慢和内存密集型的。

Image take in portrait mode will be saved in the landscape. But images taken in the landscape mode is saved correctly.

private class SaveImageTask extends AsyncTask {

@Override protected Void doInBackground(byte[]... data) {

    FileOutputStream outStream = null;
    int rotate = 0;
    try {
    File sdCard = Environment.getExternalStorageDirectory();
    File dir = new File(sdCard.getAbsolutePath() + "/SELFie");
    dir.mkdirs();
    String fileName = String.format("%d.jpg", System.currentTimeMillis());

    // Before saving to the file rotate to portrait and save it in a right ratio.

File outFile = new File(dir, fileName);
    Log.d("SaveImageTask","It is a OutPut media file");
    outStream = new FileOutputStream(String.valueOf(outFile));
    Log.d("SaveImageTask","OutStream");

      // writing data to the file

outStream.write(data[0]);
    Log.d("SaveImageTask","writing the data to the outStream");
    outStream.flush();

    Log.d("SaveImageTask","OutStream.flush");
    outStream.close();

    Log.d("SaveImageTask","closing the outStream");
    Log.d(DEBUG_TAG, "onPictureTaken - wrote bytes: " + data.length + " to " +       outFile.getAbsolutePath());

     // Refreshing the gallery to save recently taken photos.

     refreshGallery(outFile);

     // After calling the refreshGallery method.

    } catch (FileNotFoundException e) {
     e.printStackTrace();

    } catch (IOException e) {
     e.printStackTrace();

    } finally {
    }
    return null;

     // Finally returning the null.
     }
    }

Some Android camera hardware will create portrait images in landscape, with an EXIF header in the JPEG file indicating that the image viewer should rotate the image.

Some Android camera hardware will create portrait images as portrait.

There is nothing that you can really do about this. You are welcome to scan the resulting JPEG for the EXIF header and rotate the image yourself, but this is slow and memory-intensive.
