Android App Error Nullpointerexception?
I am trying to make an android app that when a button is clicked goes into the phones' directory and can open a file. Here is the code I have so far: package com.open1; import jav
Solution 1:
Your method
private File getFilesDir() {
// TODO Auto-generated method stubreturnnull;
}
returns null
whose return value is then used here:
Filelister=this.getFilesDir();
...
>>>> for (String list : lister.list()){
You are obviously referencing an object (here: lister
) that has been initialized with null
.
Care to use a debugger and/or working on your TODO
comments?
