Error: open failed: ENOENT (No such file or directory)

Question

I was trying to create a file to save pictures from the camera, it turns out that I can't create the file. But I really can't find the mistake. Can you have a look at it and give me some advice?

    private File createImageFile(){             File imageFile=null;             String stamp=new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());             File dir= Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);             String imageFileName="JPEG_"+stamp+"_";             try {                 imageFile=File.createTempFile(imageFileName,".jpg",dir);             } catch (IOException e) {                 Log.d("YJW",e.getMessage());             }             return  imageFile;         } 

And I have added the permission.

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 

The method always gives such mistakes:

open failed: ENOENT (No such file or directory)

Answer 1

The Pictures directory might not exist yet. It's not guaranteed to be there.

In the API documentation for getExternalStoragePublicDirectory(), the code ensures the directory exists using mkdirs:

File path = Environment.getExternalStoragePublicDirectory(         Environment.DIRECTORY_PICTURES); File file = new File(path, "DemoPicture.jpg");  try {     // Make sure the Pictures directory exists.     path.mkdirs();  

...so it may be as simple as adding that path.mkdirs() to your existing code before you createTempFile.
