I have an api that return blob file response in my Ionic application and using file-saver.js I am able to download it as pdf when running it on browser, but when I deploy it on android my app wont download the pdf . Is there alternative way to do it? I’m using Ionic 5 with Capacitor .

```auto
const response = await this.interactionService.generatePdf(payload).toPromise();

      FileSaver.saveAs(response, `InteractionMonitoring.pdf`);

```

Super easy with [Angular’s `HttpClient`](https://angular.io/api/common/http/HttpRequest), as you just specify `responseType: "blob"`, but I get the feeling you’re not using Angular, if any framework at all.
