Android Firebase Storage Example
<p>I am trying to use Firebase's example Storage app for testing purposes. Unfortunately, it won't work for me. I have tried countless things to no avail.</p>

<p>My error is listed below as well. I understand it is telling me there is no such file or directory but I can't seem to figure that why. Also I did confirm I have read/write privileges for external storage</p>
