How to check if newly created folder is present into SD Card in Android

问题

From my application, I want to store some images into my SD card. For that I need to create a one folder.

At the first time folder will create but after it checks whether that folder is present or not. How can I do it?

回答1:

below code will create a directory if it does not exist

   File direct = new File(Environment.getExternalStorageDirectory() + "/New Folder");

   if(!direct.exists())
    {
        if(direct.mkdir()) 
          {
           //directory is created;
          }

    }

You should request the following permission first in your Android manifest :

android.permission.WRITE_EXTERNAL_STORAGE

and execute above code by Rasel for it to work.
