为什么Environment.getExternalStoragePublicDirectory在某些设备(自2011年初开始特别制造)中不起作用? [英] Why Environment.getExternalStoragePublicDirectory is not working in some devices(specially manufactured since early 2011)?

问题描述

我正在尝试将从相机捕获的图像存储到公共存储目录，这是我用于存储图像的代码的一部分:

I am trying to store the images captured from camera to public storage directory, here is my part of code for storing image:

protected File createImageFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "JPEG_" + timeStamp + "_";
        File storageDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(
                imageFileName,  /* prefix */
                ".jpg",         /* suffix */
                storageDir      /* directory */
                );
        return image;
    }

在大多数设备上都能正常工作，但在某些设备上我能得到

its working fine in most of the devices, but in some devices i get

java.io.IOException:打开失败:ENOENT(没有这样的文件或目录)

java.io.IOException: open failed: ENOENT (No such file or directory)

所以我的问题是，为什么相同的代码在大多数设备上都能正常工作，为什么在某些设备上不能正常工作，以及如何解决此问题?

So my question is why the same piece of code is working fine in most of the devices and why not in some devices and how to fix this issue?

推荐答案

请改用context.getExternalFilesDir(Environment.DIRECTORY_PICTURES).
