title: Why Images.Media.insertImage return null
body: <p>I have some code where I run the method MediaStore.Images.Media.insertImage (inserting it from a source not a file name), This code saves the image to the MediaStore and returns the uri of the image. I know that when it fails for any reason it will return null instead of a uri. This image has been downloaded multiple times by many people and every once in a while it will return null from this method. I have never had this happen to me so I have no idea what is going on. What are reasons why this could happen? There is another <a href="https://stackoverflow.com/questions/6576217/most-likely-cause-for-android-provider-mediastore-images-media-insertimage-to-re">post</a> with the same issue but the answer is a link to the source code for MediaStore but that link goes to a page saying the link is unavailable. Any help would be appreciated. Thanks.</p>
  
  <p>After removing my SD card I got this error so I know that could be a reason, I'm not sure but I feel that it would also happen if the card was full. Still just wondering if there could be another reason too.</p>
