How do i make directories in internal storage?
I tried this:
File file = getFilesDir();
this makes me goes to folder "/data/data/com.mypackages/files/"
Then i want to make a folder again in that directories, let's say i want to make "myfiles" folder in there so it becomes, "/data/data/com.mypackages/files/myfiles/".
Can anyone tell me how?
I also tried this:
File file = getDir("myfiles", MODE_PRIVATE);
It makes the folder, but it was created with "app_", so the directories becomes "/data/data/com.mypackages/app_myfiles". I don't want that because i can't read the folder if it has "app_" in there.

The solution is under your eyes :D
m_applicationDir = new File(this.getFilesDir() + "");
m_picturesDir = new File(m_applicationDir + "/pictures");
With this code, i save in m_applicationDir the dir of the package (in your case the dir saved in file). Then simply create a sub-directory named pictures.
So m_picturesDir points to:
/data/data/com.mypackages/files/pictures
