  You have not accepted the license agreements of the following SDK components: [Android SDK Platform 24]. Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager. Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

Answer 1

My software:

Ubuntu 16.04.2 LTS
Gradle 3.5
java version "1.8.0_131"
$ANDROID_HOME = ~/AndroidSDK

Working solution:

yes | $ANDROID_HOME/tools/bin/sdkmanager "build-tools;25.0.2

of course you should use your version of build-tools.

Install the license:

In Command Prompt, go to ANDROID_HOME\tools\bin

Accept the licenses you want when it is prompted.

Install sdk 25 and accept the license from android studio. That solved my issues.
