Creating internal app directory

Question

I am trying to create a app specific directory (Internal) to store some images.I have tried many SO answers, but still nothing works. I've tried this from here.

File mydir = getApplicationContext.getDir("mydir", Context.MODE_PRIVATE); //Creating an internal dir;

But still this directory is not created - Android/data/com.packagename/....

But when I run this-

File mediaDir = new File("/sdcard/Android/data/com.packagename");
if (!mediaDir.exists()){
    mediaDir.mkdir();
}

This though creates the directory in the internal storage but is this the right way to do it ?

• And yes I've added the internal read write permissions

getApplicationContext().getDir() will not create a folder named Android/data/com.packagename/. If you log/print the path for the returned File you will see it is "/data/data/<packagename>/app_mydir/". This is the way it should be for internal storage.

If you want to create a directory on the sd card (usually referred to as external storage, even when the /sdcard path resides in internal flash storage) then use Context.getExternalFilesDir(). This will create a folder like "/sdcard/Android/data/<packagename>/files/"
