回答1:

You shouldn't rotate the image after upload. You need to rotate it before. The preview is correct maybe because you're respecting Exif values when showing it. But the server isn't.

You need to rotate the image according to it's exif rotation:

https://stackoverflow.com/a/20480741/3410697

And only then you should upload it to the server



回答2:

Call this function where you get path of image

public void setImage(String _path) {
    int orientation = CustomImageUtil.getExifOrientation(_path);
    BitmapFactory.Options resample = new BitmapFactory.Options();
    resample.inSampleSize = 4;
    Bitmap bitmap = BitmapFactory.decodeFile(_path, resample);
    if (orientation == 90) {
        bitmap = CustomImageUtil.rotate(bitmap, 90);
    } else if (orientation == 180) {
        bitmap = CustomImageUtil.rotate(bitmap, 180);
    } else if (orientation == 270) {
        bitmap = CustomImageUtil.rotate(bitmap, 270);
    }

    // use your bitmap here


}

CustomImageUtil.class:

 public class CustomImageUtil {



public static  String getRealPathFromURI(Context context,Uri contentURI) {
    String result;
    Cursor cursor = context.getContentResolver().query(contentURI, null, null, null, null);
    if (cursor == null) { // Source is Dropbox or other similar local file path
        result = contentURI.getPath();
    } else { 
        cursor.moveToFirst(); 
        int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
        result = cursor.getString(idx);
        cursor.close();
    }
    return result;
}

// method for bitmap to base64
public static String encodeTobase64(Bitmap image) {
    Bitmap immage = image;
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    immage.compress(Bitmap.CompressFormat.PNG, 60, baos);
    byte[] b = baos.toByteArray();
    String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT);

    Log.d("Image Log:", imageEncoded);
    return imageEncoded;



}

/**

public static int getExifOrientation(String filepath) {

                (float) b.getHeight() / 2);
        try {
            Bitmap b2 = Bitmap.createBitmap(b, 0, 0, b.getWidth(),
                    b.getHeight(), m, true);
            if (b != b2) {
                b.recycle();
                b = b2;
            }
        } catch (OutOfMemoryError ex) {ex.printStackTrace();
        }
    }
    return b;
}


 }

To convert Bitmap to Uri

public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
