Version r23b was a patch update for the r23 LTS branch. Here is why it remains relevant for many projects:
LTS Stability: As a Long Term Support release, it focuses on stability rather than experimental features.
LLVM Toolchain: It uses Clang/LLVM 12 as the primary compiler.
Removal of GNU Binutils: This version pushed further into using LLVM tools (like llvm-strip, llvm-objcopy) over the older GNU counterparts. download androidndkr23blinuxx8664zip top
Glibc Support: It requires a relatively modern Linux host (glibc 2.17+), which covers most distributions from the last decade (Ubuntu 14.04 and newer). 3. Quick Setup Guide for Linux
Once you have downloaded the zip file, follow these steps to integrate it into your environment: Extract the Archive: unzip android-ndk-r23b-linux.zip -d ~/android-sdk/ndk/ Use code with caution. Copied to clipboard
Set Environment Variables:Add these lines to your ~/.bashrc or ~/.zshrc:
export ANDROID_NDK_HOME=$HOME/android-sdk/ndk/android-ndk-r23b export PATH=$PATH:$ANDROID_NDK_HOME Use code with caution. Copied to clipboard Permissions:Ensure the toolchain binaries are executable: chmod -R +x $ANDROID_NDK_HOME/toolchains Use code with caution. Copied to clipboard 4. Common Troubleshooting
Missing Dependencies: If you are on a bare-bones Linux server, you might need libncurses5. Fix: sudo apt-get install libncurses5
Compatibility: If your project still requires GCC, note that r23 has completely removed it. You must migrate your build scripts to use Clang. The Android NDK r23b is a significant Long

Create hello.c:
#include <stdio.h>
int main()
printf("Hello from NDK!\n");
return 0;
Compile for ARM64:
$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang hello.c -o hello
Solution: The PATH is not set correctly. Use the absolute path:
/opt/android-ndk-r23b/ndk-build
unzip installed: sudo apt install unzip (Debian/Ubuntu) or sudo yum install unzip (RHEL/CentOS).Open your terminal and navigate to your preferred downloads directory (e.g., ~/Downloads or /opt). If you don’t have wget (rare)
cd /opt
sudo wget https://dl.google.com/android/repository/android-ndk-r23b-linux-x86_64.zip
If you don’t have wget (rare), use curl -O [URL] instead.
Even when downloading from the top source, you might encounter issues. Here is how to fix them.
To ensure everything is working correctly, run the following command to check the NDK version:
~/android-ndk-r23/ndk-build --version
You should see output confirming the version number (e.g., GNU Make 4.2.1).
