Answer: 
Late but you should encode your url,

```
try {
    url=URLEncoder.encode(url,"UTF-8");
    myWebView.loadUrl("https://docs.google.com/gview?embedded=true&url="+url);
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
}

```
I think your problem when you upload the file to firebase, you should add metadata of your uploaded file
in you case you should define StorageMetadata and set contentType of "application/pdf"

This code from iOS app

```
FIRStorageMetadata* metadata = [[FIRStorageMetadata alloc] init];
metadata.contentType = @"application/pdf";

```

and then when you put data to firebase add this metadata in upload function
