Android error: Error while casting ReactNativeBlobUtilFileResp

[ricbermo]

Hello, thanks for taking your time to maintain this library.
Somedays, ago, the "download" stopped working. I was able to track down and fix the issue (credits to @srbulovicdusan).

So, here's an image of the error

The fix is,

1. go to ReactNativeBlobUtilFileResp.java and add a new constructor like this:

public ReactNativeBlobUtilFileResp(ResponseBody body) {
  super();
  this.originalBody = body;
}

then, in ReactNativeBlobUtilReq.java around line 607 replace how ReactNativeBlobUtilFileResp is instanciated.

// remove or comment
ReactNativeBlobUtilFileResp = (ReactNativeBlobUtilFileResp) responseBody;
// use this
ReactNativeBlobUtilFileResp = new ReactNativeBlobUtilFileResp(responseBody);

Important information:

1. RN version: 0.64.2
2. lib. version: 0.13.18

Note: I was not able to reproduce this issue on a "clean" RN project.

Fix found here

Thank you for the fix. In general the usage of a constructor is of course better than a cast. Even though I don't completely understand why the cast didn't work here.

in my case this exception is happened on some device only, is there any workaround for this?

So far, no. Unless we figure out why the cast isn't working or get it working with a costructor.
