Eddie Android edition 4.1.0 preview available

[Staff 10581]

Hello! 

We're very glad to announce the Eddie Android edition 4.1.0 preview is available
UPDATE 2026-07-18 Eddie Android edition 4.1.0 beta 2 is available

Eddie Android edition 4.1.0 development focuses exclusively on improving stability by introducing a new custom AirVPN library that combines wg-go and amneziawg-go into a single runtime. This architectural change addresses a fundamental constraint of the Go runtime. Go was designed with the assumption that only one runtime instance exists per process and does not support multiple independent runtimes within the same process. Consequently, the runtime assumes exclusive ownership of global resources such as the heap, scheduler, stack management, and other core runtime components.
 

The current production version had been linked against two separate Go-based libraries since support for Amnezia WireGuard was introduced. Despite the precautions implemented, on a small subset of devices, this configuration still resulted in crashes during approximately 1% to 5% of application launches. Analysis showed that all such crashes originated from Go runtime components, most notably the garbage collector. By consolidating both libraries into a single Go runtime, Eddie Android Edition 4.1.0 is expected to eliminate these crashes across all supported devices.

Furthermore, Eddie Android edition adheres more strictly to AmneziaWG protocol version 2 real implementations. Specifically:

• The <c> tag for I parameters has been removed. Although documented for about a year, it was never implemented in the AmneziaWG protocol and any implementation intent was dropped during February 2026. Because, regrettably, it remained in the Amnezia documentation, Eddie 4.0.x still generated this parameter in certain profiles, resulting in the well-known interoperability issues with other clients. Eddie 4.1.0 eliminates this inconsistency. See: https://github.com/amnezia-vpn/amneziawg-go/issues/120
• Added support for the <rc> and <rd> tags for I parameters.
• J parameters must now be ≥ 1. Previous Eddie / Amnezia releases accepted values ≥ 0, making it possible to explicitly configure zero junk packets, thereby allowing users to explicitly configure a logically degenerate state in which the junk-packet mechanism remained enabled while simultaneously instructing it to emit precisely zero junk packets. This is no longer supported; to disable junk packet generation, simply omit the J parameters.
• WireGuard compatibility now requires the canonical header mapping (Hₙ = n), as packet header identifiers are interpreted in a strict semantic order. Earlier AmneziaWG implementations, including that used by Eddie 4.0.x, internally canonicalized header mappings, allowing any non-repeating permutation of {1, 2, 3, 4} to preserve WireGuard compatibility. Eddie now enforces the canonical mapping whenever interoperability with standard WireGuard peers is required, including connections to AirVPN servers using the default Amnezia configuration.

  Eddie Android Edition 4.1.0 also includes updated libraries and dependencies. Please refer to the changelog below for additional details.

This is a build debug package and side load is mandatory.

If you decide to test, please report at your convenience any bug and problem in this thread. If possible generate a report from the app in a matter of seconds: by tapping the paper plane icon on the Log view bar rightmost side you will generate a full system report which will include both log and logcat and have it sent to our servers. Then you just need to send us the link the app shows you (open a ticket if you prefer to do it in private).

Hello!

We're very glad to inform you that Eddie Android edition 4.1.0 beta 2 is now available. Please refer to the original message for important updates and details.

Kind regards

I just updated to beta 2.
Now ooften I get an error when opening the app and it doesn't connect. 
When iI close and reopen the app it connects but the connection doesn't work, in bytes stays 0.
I have shared my log through a ticket. 
Edit:When I re randomise the amnesia parameters it works

Hello!

Thank you very much for your tests and report. We can reproduce similar problems and we are investigating. In the meantime, please try this:

• from Android application settings, delete Eddie data (both data and cache)
• uninstall Eddie
• re-install Eddie and report back

The above procedure can mitigate one of the problems we detected thanks to your report, but we have found other problems (when using Eddie in Amnezia mode) and a thorough investigation is going on. We will keep you posted.

Kind regards
