Hey Android Builder Community, Today I am going to present you a Download Extension with very advanced features.

  3. It always resumes download, also in any error like download failed, network error, link expired, etc. ( In case of link expiration you have to use a different link of the same filename )

I found, this is nice extension but one one thing isn’t good and that’s is its not downloading all urls .
Only specific urls accept and most of the urls ut says “permission denied”

I was previously offline for some time, but I am now back to work. I will make an effort to correct any errors and create a new version of this extension that is free from bugs or other issues as soon as possible :+1:
