You have not accepted the license agreements of the following SDK components [duplicate]

Question

I downloaded the latest Android SDK tools version 24.4.1. I used the command line to install SDKs. I typed y when asked

Do you accept the license 'android-sdk-license-c81a61d9' [y/n]: y after that install succeeded.

But when using Gradle 3.1 to build, the follows shows up

You have not accepted the license agreements of the following SDK components: [Android SDK Platform 23, Android SDK Build-Tools 23.0.1]. 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

I checked ~/.android and /opt/android-sdk where Android tools are put. Neither contain folder named licenses.

Answer 1

The way to accept license agreements from the command line has changed. You can use the SDK manager which is located at: $ANDROID_SDK_ROOT/tools/bin

e.g on linux:

cd ~/Library/Android/sdk/tools/bin/ 

Run the sdkmanager as follows:

./sdkmanager --licenses 

e.g on Windows:

cd /d "%ANDROID_SDK_ROOT%/tools/bin" 

Run the sdkmanager as follows:

sdkmanager --licenses 

And accept the licenses you did not accept yet (but need to).

For more details see the Android Studio documentation, although the current documentation is missing any description on the --licenses option.

Warning

You might have two Android SDKs on your machine. Make sure to check both ~/Library/Android/sdk and /usr/local/share/android-sdk! If unsure, fully uninstall Android Studio from your machine and start with a clean slate.

Update: ANDROID_HOME is deprecated, ANDROID_SDK_ROOT is now the correct variable

Answer 2

You can install and accept the license of the SDK & tools via 2 ways:

1. Open the Android SDK Manager GUI via command line

Open the Android SDK manager via the command line using:

# Android SDK Tools 25.2.3 and lower - Open the Android SDK GUI via the command line cd ~/Library/Android/sdk/tools && ./android  # 'Android SDK Tools' 25.2.3 and higher - `sdkmanager` is located in android_sdk/tools/bin/. cd ~/Library/Android/sdk/tools/bin && ./sdkmanager 

View more details on the new sdkmanager.

Select and install the required tools. (your location may be different)

2. Install and accept android license via command line:

Update the packages via command line, you'll be presented with the terms and conditions which you'll need to accept.

- Install or update to the latest version

This will install the latest platform-tools at the time you run it.

# Android SDK Tools 25.2.3 and lower. Install the latest `platform-tools` for android-25 android update sdk --no-ui --all --filter platform-tools,android-25,extra-android-m2repository  # Android SDK Tools 25.2.3 and higher sdkmanager --update 

- Install a specific version (25.0.1, 24.0.1, 23.0.1)

You can also install a specific version like so:

# Build Tools 23.0.1, 24.0.1, 25.0.1 android update sdk --no-ui --all --filter build-tools-25.0.1,android-25,extra-android-m2repository android update sdk --no-ui --all --filter build-tools-24.0.1,android-24,extra-android-m2repository android update sdk --no-ui --all --filter build-tools-23.0.1,android-23,extra-android-m2repository # Alter the versions as required                      ↑               ↑  # -u --no-ui  : Updates from command-line (does not display the GUI) # -a --all    : Includes all packages (such as obsolete and non-dependent ones.) # -t --filter : A filter that limits the update to the specified types of #               packages in the form of a comma-separated list of #               [platform, system-image, tool, platform-tool, doc, sample, #               source]. This also accepts the identifiers returned by #               'list sdk --extended'.  # List version and description of other available SDKs and tools android list sdk --extended sdkmanager --list
