Upload of MediaFiles is always returning NullPointException
<p>I am encountering this weird error when uploading voice recordings from the Android device to an backend.</p>

<p>I am getting the following error and nothing is uploaded:</p>

<p>java.lang.NullPointerException
at java.io.File.fixSlashes (File.java.=:205)</p>

<p>The file name consists of the data timestamp, I have tried without data timestamp and still have the same error.</p>

<p>The weird part is that, I have tested with textfiles and it gets uploaded without any issue nor exception.</p>

<p>Anyone knows what's the issue?</p>

<p>Thanks In Advance</p>
