android deleting a file from internal storage

Question

I have created a file stored on internal storage from an activity. How can I delete this file from another activity?

I'm thinking I'll have to get the file's directory (which I'm not sure how to) and delete it. I tried using

context.deleteFile(); 

but it won't work because I'm trying to call it from a non-static method.

Answer 1

You can try getting the instance pointing to the file and deleting it like in this answer or this one

Answer 2

Here is your answer :

File dir = getFilesDir();
File file = new File(dir, "my_filename");
boolean deleted = file.delete();
