Android NDK Apple SiliconM1 run into: Unknown host CPU architecture arm64
android, android-ndk, apple-m1, apple-silicon
Solution
To solve this on a Apple Silicon M1 I found three options
A
Use NDK 24
android {
ndkVersion "24.0.8215888"
...
}
You can install it with
echo "y" | sudo ${ANDROID_HOME}/tools/bin/sdkmanager --install 'ndk;24.0.8215888' 1>/dev/null
B
convert your `ndk-build` into a `cmake` build
C
Change your `ndk-build` to use Rosetta x86. Search for your installed ndk with
find ~ -name ndk-build 2>/dev/null
eg
vi ~/Library/Android/sdk/ndk/22.1.7171670/ndk-build
and change
DIR="$(cd "$(dirname "$0")" && pwd)"
$DIR/build/ndk-build "$@"
to
DIR="$(cd "$(dirname "$0")" && pwd)"
arch -x86_64 $DIR/build/ndk-build "$@"
D
Use a x86 Android Studio version. But this is slow
Problem
There are two kinds to build Android with NDK cmake ``` externalNativeBuild { cmake { path "../sharedCode/CMakeLists.txt" } } ``` This works fine with Apple Silicon M1 ndk-build ``` externalNativeBuild { ndkBuild { path "src/main/jni/Android.mk" } } ``` On a Apple Silicon M1 I run into ``` Unknown host CPU architecture arm64 ``` The question is to solve this ?
