通过Homebrew安装的Android NDK无法本地化问题求助

DevOps 小满

2026-5-26

Hey there, let's work through this Android NDK localization issue together. From what you've described, here are targeted fixes to try out:

1. Confirm your environment variables are actually active

First, let's make sure the system is picking up your NDK path correctly. Open a new terminal window and run these commands:

echo $ANDROID_NDK_HOME
echo $PATH | grep android-ndk

If the first command doesn't output /usr/local/Caskroom/android-ndk/16b/android-ndk-r16b, or the second shows no match, your environment variable configuration isn't taking effect. Double-check which shell config file you're using (e.g., ~/.bash_profile for Bash, ~/.zshrc for Zsh) and ensure you've either restarted your terminal or reloaded the file with:

source ~/.zshrc  # or source ~/.bash_profile depending on your shell

2. Fix version compatibility between NDK and Gradle

NDK r16b is a fairly old release, and newer Gradle plugins (4.0+) often drop support for older NDK versions. If your project uses a recent Gradle setup, you have two options:

Option 1: Upgrade your NDK to a version compatible with your Gradle plugin (check the Android Gradle Plugin's documentation for compatible NDK versions)

Option 2: Explicitly specify the NDK version in your project's module-level build.gradle file:

android {
    ndkVersion "16.1.4479499"  // This is the full version number corresponding to r16b
}

3. Force Gradle to use your NDK path via local.properties

Gradle prioritizes the local.properties file over system environment variables. If you don't already have this file in your project root directory, create it and add these lines:

sdk.dir=/usr/local/Caskroom/android-sdk/3859397
ndk.dir=/usr/local/Caskroom/android-ndk/16b/android-ndk-r16b

This removes any ambiguity about where Gradle should look for your SDK and NDK.

4. Fix your PATH variable configuration

Your provided PATH snippet cuts off, but ensure you're adding the NDK directory to your PATH so system tools can find NDK binaries like ndk-build. Update your shell config with:

export PATH=$ANDROID_NDK_HOME:$PATH

Don't forget to reload the config file or restart your terminal after making this change.

5. Clear build caches and restart your IDE

Sometimes stale caches can cause path resolution issues. First, close your IDE (Android Studio or whatever you're using), then run these commands in your project directory:

./gradlew clean
./gradlew build --refresh-dependencies

Reopen your project afterward and try building again.
