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 ?
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
