Question

I’m in the process of making an Android application that creates a new file when a button is pressed. I’m using the following code:

File file = new File(Environment.getExternalStorageDirectory()
         +File.separator
         +"myDirectory" //folder name
         +File.separator
         +"myFile.png"); //file name
file.mkdirs();

However, myFile.png is actually being displayed as a directory and not a .png file.

Answer 1

Because of file.mkdirs(); mkdirs() – is used for making directory by filename given file object’s parameter, If you want to make a file make IO operation for writing in a file,

In your case: to make a directory,

File file = new File(Environment.getExternalStorageDirectory()
     +File.separator
     +"myDirectory" //folder name
     +File.separator
     +"myFile.png"); //file name
   file.getParentFile().mkdirs();

This make a myDirectory folder in external storage.
