Automatically accept all SDK licences

Question

Since gradle android plugins 2.2-alpha4:

Gradle will attempt to download missing SDK packages that a project depends on

Which is amazingly cool and was know to be a JakeWharton project.

But, to download the SDK library you need to: accept the license agreements or gradle tells you:

You have not accepted the license agreements of the following SDK components: [Android SDK Build-Tools 24, 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

And this is a problem because I would love to install all sdk dependencies while doing a gradle build.

I am looking for a solution to automatically accept all licenses. Maybe a gradle script ? Do you have any ideas ?

Answer 1

UPDATE 2021 This should be the accepted answer as its easy and upto date

AndroidSDK can finally accept licenses.

Go to Android\sdk\tools\bin

yes | sdkmanager --licenses 

EDIT:

as pointed out in the comments by @MoOx, on macOS, you can do

yes | sudo ~/Library/Android/sdk/tools/bin/sdkmanager --licenses

as pointed out in the comments by @pho, @mikebridge and @ Noitidart on Windows, you can do

cmd.exe /C"%ANDROID_HOME%\tools\bin\sdkmanager.bat --licenses"

be sure to install java before

Answer 2

I was getting this error:

License for package Android SDK Build-Tools 30.0.2 not accepted. 

So, I went to Tools -> SDK Manager -> SDK Tools. Then I installed Google Play Licensing Library. It solved the problem.
