Open a PDF on Android and iOS

Question

Okay this has been haunting me for a couple of days, I have this project one of its features is that it would have this button that would open a local pdf file for the user. However, the project is intended for Android and iOS.

What I achieved so far is locating the pdf file from the .apk on android (I haven't tested it on iOS yet). I used the WWW class to do so, and I checked for the size and it returned the true size of the PDF (Which proves that I have the correct file).

The problem is that I can only access the file through the WWW class (to get the size for example), How do I open it through www.assetBundle.mainAsset?

My thoughts were that I should first save the pdf file in a temporary location and use the OpenURL or maybe the process.start to open it. But I can't figure out how to do that either.

I have done tones of research and got this far and I can't find anything online that would help me to take this last step, so if anyone can help me with it, please tell me.

Thanks

EDIT: The code I used is

 IEnumerator Start() {
         if(Application.platform == RuntimePlatform.Android){
             path =Application.streamingAssetsPath + "/The_100.pdf";
         }else{
             path = "file://"+Application.streamingAssetsPath + "/The_100.pdf";
         }
         WWW www = new WWW(path);
         yield return www;
 }

when I use www.size it returns the correct size of the pdf file

I have figured out how to save the file to the Application.persistentDataPath The code I used:

     IEnumerator Start() {
         if(Application.platform == RuntimePlatform.Android){
             path =Application.streamingAssetsPath + "/The_100.pdf";
             savePath = Application.persistentDataPath;
         }else{
             path = "file://"+Application.streamingAssetsPath + "/The_100.pdf";
             savePath = "C:/Users/IBRAHI/Desktop/SaveTestUnity";
         }
         WWW www = new WWW(path);
         yield return www;
         error = www.error;
 
         byte[] bytes = www.bytes;
         result = "Done, bytes downloaded, File size : "+bytes.Length;
         try{
             File.WriteAllBytes(savePath+"/The_100.pdf", bytes);
             error = "No Errors so far";
         }catch(Exception ex){
             error = ex.Message;
         }
         Application.OpenURL(savePath+"/The_100.pdf");
     }

Thanks
