Hi,  
Thank you for contacting Bitrise.

This root cause is that the ndk version in your project’s setting is different from the ndk version pre-installed on Bitrise stacks.

Currently, the pre-installed ndk version is `24.0.8215888` and you can check the [system report](https://github.com/bitrise-io/bitrise.io/tree/master/system_reports/MACOS/INTEL) for further details.

Here’re two ways to solve this issue:

1. Update the ndk version to `24.0.8215888` in your project setting, or
2. Install the ndk version you’re using locally with the `Install missing Android SDK components` step at the beginning of the workflow.

Besides that, you will also need to specify the ndk path for Gradle.

### Using Android Gradle plugin before v3.5.0

You’d need a **local.properties** file and define the ndk.dir variable.  
Since local.properties is not recommended to be stored in git, please add a **script step** after git clone step and use the following script to create a **local.properties** file.

```auto
#!/usr/bin/env bash
echo ‘Generating local.properties ...’
echo $ANDROID_HOME
cat > “./local.properties” <<- FILE_CONTENT
sdk.dir=$ANDROID_HOME
ndk.dir=$ANDROID_HOME/ndk/21.4.7075529
FILE_CONTENT

```

### Using Android Gradle plugin v3.5.0 or higher

You’d need to define the ndkVersion in your **build.gradle** file.

```auto
android { ndkVersion "xx.x.xxxxx" // e.g., ndkVersion "24.0.8215888"}

```

You can check [https://developer.android.com/studio/projects/install-ndk#apply-specific-version](https://developer.android.com/studio/projects/install-ndk#apply-specific-version) for further information.

Hope this helps!

Thanks,  
Han
