Advanced Download Manager (ADM) is still the top pick in 2026, actively maintained with over 100 million installs and a 4.3-star rating. 1DM is the strongest newer alternative, built around the same multi-segment download splitting that made desktop tools like IDM fast. One real change since this article was last accurate: Android’s scoped storage rules, tightened since Android 10, mean a download manager now typically saves to the public Downloads folder automatically rather than asking for broad storage permission upfront.
Advanced Download Manager, still the default recommendation
ADM splits downloads across multiple threads, resumes interrupted downloads reliably, and supports scheduling and bandwidth allocation. It’s free, and its install numbers and rating have held up: still updated, still widely used. Some recent user reports mention ad-injection before video downloads and occasional “operation not permitted” errors, which is consistent with Android’s storage permission changes rather than the app itself being abandoned, worth trying a fresh permission grant if you hit that specific error.
1DM, the strongest newer option
1DM works on the same principle as desktop download accelerators, splitting a file into segments and downloading them in parallel, with a built-in browser and torrent support. It’s the closest current Android equivalent to what desktop tools like IDM do, and it’s a legitimate alternative to ADM if you want a second option or ADM isn’t behaving well on your specific phone.
What actually changed since this article’s original version
Per Android’s own developer documentation, scoped storage, introduced in Android 10 and tightened in later versions, changed how apps read and write shared storage. A download manager today typically saves files to the public Downloads folder through Android’s MediaStore system without asking for broad permission, but full folder management may prompt for “All Files Access,” which you grant manually in Settings if an app asks. This is a real behavior change from 2020, when a single storage-permission popup covered everything.
Frequently asked questions
Is ADM still the best free download manager for Android? Yes, it remains the most widely used and actively updated option, with 1DM as the strongest current alternative.
Why does my download manager ask for “All Files Access”? Android’s scoped storage rules restrict broad folder access by default since Android 10. An app needs this specific permission to manage files outside its own folder and the public Downloads directory.
Why do I get an “operation not permitted” error? This is commonly tied to Android’s storage permission changes rather than a broken app. Check the app’s storage permission in Settings and re-grant it if needed.
