Issue
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)
Solution
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
.
