[Android] Build fails on Flutter 3.38.5: "Android NDK Clang could not be found" #180163
Description
Steps to reproduce
Build the project with flutter build apk --release
Expected results
The APK generation.
Actual results
The command flutter build apk --release fails with: Android NDK Clang could not be found..
The problem does not occur if I remove the cupertino_http dependency or use Flutter version 3.35.7.
Code sample
Since the code for this issue is irrelevant, I'm attaching the pubspec.yaml.
pubspec.yaml

description: "A new Flutter project."
# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter

@MatteoBax thanks for the report. Since it is specific to that package I recommend filing it https://github.com/dart-lang/http/issues. We can take a look if you're redirected here.
Also that package is specific to iOS/macOS.

I got the same issue, but do not have
cupertino_http,sentry_flutterorANDROID_NDK_HOME.Any recommended fixes?
I have downgraded to "resolve" this.Update: i was integrating melos for my packages at the same time, apparently (somehow) this was the cause. Downgrading to an older flutter release dit not solve my problem, removing melos did.

@EvertJanDeBruin I've landed a fix on main #180594, does switching to the main channel resolve your issue? (It might also already be in the latest beta.)

@dcharkes is there something we can cherry pick into the 3.41 beta (the next stable)Confirmed the linked pr is in 3.41 which is a beta but will be the next stable. ETA sometime in feb 2026
moodless3 commentedon Jan 28, 2026
switch to beta channel . then apply upgrade , it will avoid this issue for sure . other work arounds wont
jake-johnson-disney commentedon Feb 2, 2026
in our case we hit this issue in our GitHub Actions workflow on ubuntu-latest. The root cause was our disk cleanup step was deleting the pre-installed NDK:
The NDK is pre-installed on GitHub's ubuntu-latest runners, and Flutter 3.38.x needs it for native asset compilation. While Flutter can auto-install the NDK via sdkmanager, removing the entire /ndk directory before the build causes this failure.
Fix options:
Don't delete the NDK directory in cleanup steps
If you must free disk space, only delete specific old NDK versions you don't need
Explicitly reinstall the required NDK after cleanup:
echo "y" | $ANDROID_HOME/cmdline-tools/latest/bin/sdkmanager --install "ndk;YOUR_VERSION"This may help others seeing this error only in CI but not locally.
westito commentedon Feb 10, 2026
The only one working solution I found was adding
"android-ndk": "{{Your android SDK dir}}/sdk/ndk/28.2.13676358",to~/.config/flutter/settingsfilexlk777 commentedon Mar 5, 2026
export ANDROID_NDK_HOME=your ndk home
Mind-Reaper-Shuk commentedon Mar 23, 2026
I solved by deleting all folders of ndk higher than the one you intend to use.
e.g I wanted to use 29.0.14206865 , so I deleted existing folders of ndk 30
