Picasso为PNG文件打印JPG错误

Question

我的应用程序工作正常但我在日志中发现了一些奇怪的东西。当我打开刚刚生成Picasso打印的PNG文件时，打开JPEG图像会遇到麻烦：

10-13 18:15:41.883 10275-10615/lelisoft.com.lelimath.debug I/ExifInterface_JNI: Raw image not detected
10-13 18:15:41.885 10275-10615/lelisoft.com.lelimath.debug W/ExifInterface: Invalid image: ExifInterface got an unsupported image format file(ExifInterface supports JPEG and some RAW image formats only) or a corrupted JPEG file to ExifInterface.

图片是通过以下方式生成的：

File file = new File(getContext().getExternalFilesDir(Environment.DIRECTORY_PICTURES), figure.getId() + ".png");
fos = new FileOutputStream(file);
log.debug("Saving picture bitmap to " + file.getAbsolutePath());
bmp.compress(Bitmap.CompressFormat.PNG, 95, fos);
fos.close();

图片加载了以下代码：

File file = new File(getContext().getExternalFilesDir(Environment.DIRECTORY_PICTURES), figure + ".png");
if (file.exists()) {
    Picasso.with(getContext()).load(file).into(view);
} else {
    Picasso.with(getContext()).load(resource).into(view);
}

我下载了这张图片，我可以在二进制视图中看到PNG标题。 Windows可以打开它，XnView失败。知道那里有什么问题吗？
