It sounds like you're looking for the Android NDK Revision 23b for Linux. This specific version is often required for older projects or specific compatibility needs in mobile development.
Below is an article covering why this version matters and where you can safely find it.
Navigating the Android NDK: Why Revision 23b Remains a Developer Staple
In the fast-evolving world of Android development, "newer" isn't always "better" for every project. While Google frequently pushes out new versions of the Native Development Kit (NDK), many developers still find themselves searching for the Android NDK r23b (Linux x86_64).
Whether you are maintaining a legacy codebase or dealing with specific toolchain requirements, having the right version is critical for a stable build. What is Android NDK r23b?
The NDK is a toolset that allows you to implement parts of your app in native code, using languages like C and C++. Revision 23b was a significant stable release that addressed several bugs found in the initial r23 rollout.
It is particularly known for its stability with LTS (Long Term Support) projects. Many cross-platform engines and libraries were calibrated specifically for the r23 cycle before Google moved toward the newer Clang-based builds in r24 and beyond. Why You Might Need This Specific Version
Toolchain Consistency: If your CI/CD pipeline was built around r23b, upgrading can lead to unexpected compiler errors or performance regressions.
Compatibility: Certain third-party libraries (like older versions of FFmpeg or game engines) have strict dependencies on the header files and libraries provided in this specific revision.
Stability: r23b fixed critical issues related to libandroid_support and certain architecture-specific crashes that plagued earlier versions. How to Download Safely
When downloading development tools, it is vital to use official sources to avoid compromised binaries. You can find the archived versions on the Official Android NDK Wiki or via the direct Google storage links.

Regarding the "hot" feature mentioned in your request, this likely refers to Hot Reload or Live Edit, which allows you to see UI changes in real-time without a full rebuild. While these features are more common in Jetpack Compose or Flutter, the NDK also supports Profile-guided Optimization (PGO) to identify "hot" regions of code—frequently executed sections—for aggressive performance optimization. Home · android/ndk Wiki - GitHub
The air in the server room was a hum of static and chilled oxygen—the only place where
felt truly at home. On his screen, a single line of text blinked in a Terminal window, a relic from an encrypted forum that shouldn't have existed: subject: "download androidndkr23blinuxx8664zip hot"
To a layman, it looked like a broken link to an outdated Android Native Development Kit. To Elias, it was a "hot" signal—a live exploit hidden inside a legacy toolchain. The Decryption
Elias didn't just click "download." He mirrored the traffic through three layers of virtual machines. As the 1.2GB file began to pull from a ghost server in Reykjavik, he watched the packet headers. They weren't standard Google signatures. Someone had repacked the NDK with a sidecar—a phantom library that executed the moment the compiler was initialized. The Discovery Once the zip file landed, Elias ran a recursive hash check. The standard NDK: Clean.
The "Hot" payload: Hidden deep within the toolchains folder under a fake documentation file named README_legacy_arch.txt.so.
He opened the binary in a hex editor. It wasn't a virus; it was a map. The code didn't steal passwords—it transmitted a single set of GPS coordinates and a timestamp. The Confrontation
The coordinates pointed to a decommissioned satellite uplink station three miles from his house. The timestamp? Twenty minutes from now.
Elias realized the "hot" in the subject line wasn't about the file being popular or a "hot fix." It was a thermal warning. The script was designed to override the cooling fans on any device that ran it, potentially causing a hardware fire to mask the data transmission. The Resolution
He killed the process, but the uplink had already begun. He had two choices: delete the evidence and run, or use the modified NDK to send a "poison pill" back up the stream.
With five minutes left on the clock, his fingers flew across the mechanical keyboard. He didn't just stop the transmission; he looped it. Whoever was waiting at those coordinates would receive nothing but a 1.2GB file of "Rick Astley" encoded into raw binary data.
As the terminal cleared, Elias took a sip of his now-cold coffee. The "hot" download was neutralized. If you'd like to take the story further, let me know: Should Elias go to the coordinates himself?
Should the story pivot into a cyber-heist or a horror thriller?
For latest projects, consider NDK r26+ (available on developer.android.com). Use r23 only if you need legacy toolchain compatibility.
