Android: unable to create a directory in default pictures folder

This is the code i am using to create a folder in the default pictures folder:

File imagesFolder = new File(Environment.DIRECTORY_PICTURES, "/images");
if (!imagesFolder.exists()) {
Log.d("if imagesFolder exists - 1", "False");
imagesFolder.mkdirs();
} else {
Log.d("if imagesFolder exists - 1", "True");
}
if (!imagesFolder.exists()) {
Log.d("if imagesFolder exists - 2", "False");
imagesFolder.mkdirs();
} else {
Log.d("if imagesFolder exists - 2", "True");
}

in log i am getting:

False

False

for the 1st time the directory is not present, hence False but then immediately i am creating it using mkdirs(), hence i expect the 2nd log to be True but even that is False and my application crashed because of NullPointerException in the later part of the code

Please help

Thank You

  • You are using Environment.DIRECTORY_PICTURES the wrong way. It's just a String constant like "Pictures" but not a path. You need to get the path via Environment.getExternalStoragePublicDirectory(string)

    File pictureFolder = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES
        );
File imagesFolder = new File(pictureFolder, "images");
// etc
