Question

So I created a folder in the internal storage like this:

File folder1 = getBaseContext().getDir("DataBase", Context.MODE_PRIVATE); //Creating an internal dir;

Now how to I create a new folder inside that folder1?

I tried this (below), but this creates a file and not a folder. . .

File insideFolder = new File (folder1,"Important Database");

I also tried calling mkdir but it seems like insideFolder is still a file.

Now how to I create a new folder inside that folder1?

new File(folder1, "subdirname").mkdir();

Now how to I create a new folder inside that folder1?

If the file was already there due to some previous experiment of yours, mkdir() will not delete it. You will need to delete it yourself.
