Cannot reach files inside the root directory of my Android app

I have the code bellow:

String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/data/data/com.example.stavr.mydiary";
File file=new File(path);
File[] files = file.listFiles();
String arr[]=file.list();
List l=new ArrayList<>();
for(String i:arr){
    if(i.endsWith(". txt")){
        l.add(i);
    }
}

which returns 0 files on my array (NullPointerException to be exact), Iknow that there are files in that directory. If i change the directory to just

Environment.getExternalStorageDirectory().getAbsolutePath()

the code work and it returns all the files. I thing that i have done something wrong with the permissions. Could you please help me, Thank you very much in advance..!!!

It seems you're trying to access your internal app data folder, you can do that by using a context object: String dir = context.getFilesDir().getAbsolutePath();

If you still want to access external storage then you should make sureyou have WRITE_EXTERNAL_STORAGE permission in your AndroidManifest.xml
