Build failure for mapbox example

Hello, all!
I have built some applications on unity and without any problems and now I am trying to build mapbox example (Traffic and Direction) as an android application but I am getting this error

I checked the number minSdkVersion in the file specified and it is equal to 24

and tried to edit it and rebuild the scene but the same error pops again
and I uninstall Android SDK and install it again, but the build fails again
Here is the commands in console

CommandInvokationFailure: Gradle build failed.
C:/Program Files/Java/jdk1.8.0_211\bin\java.exe -classpath "C:\Program Files\Unity\Hub\Editor\2018.4.9f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-5.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"

or increase this project's minSdk version to at least 24,
or use toolsverrideLibrary="com.mapbox.android.unity" to force usage (may lead to runtime failures)

Any help will be appreciated

 

I solved this by changing the minimum API Level in my project settings.
In Unity : Edit -> Project Settings -> Player -> Other Settings -> Minimum API Level -> change it to Android 7.0 (API Level 24).
