Question

In my app, I used this code:

File DirectoryPath = cw.getDir("custom", Context.MODE_PRIVATE); 

While creating a directory, and it returns:

/data/data/com.custom/app_custom**

So my question is why this app_ appears along with directory name. I know its default, but what actually it means?

And secondly, how can I create a sub-directory inside my directory i.e. app_custom in this case. if anyone knows please help me to understand this concept of getDir.

You can create a new Directory using the path that you are getting from getDir(),

        File file = getDir("custom", MODE_PRIVATE);
        String path = file.getAbsolutePath();
        File create_dir = new File(path+"/dir_name");
        if(!create_dir.exists()){
            create_dir.mkdir();
        }
