I found out that each time Travis CI build the project, it has to download again all the SDK packages like the platform-tools, the support library, the current SDK, etc.
Is it possible to avoid it and make Travis reuse what it downloaded the first time ?
I probably made some mistakes in my .travis.yml file, here is a copy of it
language: android
android:
components:
# Uncomment the lines below if you want to
# use the latest revision of Android SDK Tools
- platform-tools
- tools
# The BuildTools version used by your project

- android-23
# Additional components

script:
- ./gradlew check
- ./gradlew test --continue
# - ./gradlew build connectedCheck
Why do Travis CI download everything each time it builds?
We talk about this here, Travis-ci downloads the cache from S3, so there is not a significant speed improvement caching big files like Android SDK.
How to include Android SDK in Travis-ci cache? (not recommended)
The relevant bits are here, you can add to the cache any file you like and know his path:
cache:
directories:
- ${TRAVIS_BUILD_DIR}/gradle/caches/
- ${TRAVIS_BUILD_DIR}/gradle/wrapper/dists/
- ${TRAVIS_BUILD_DIR}/android-sdk/extras/ # please don't include sys-images
I did it time ago, you can see the code in the link shared by #nicolas-f:
language: android
jdk: oraclejdk8
env:
global:
- GRADLE_USER_HOME=${TRAVIS_BUILD_DIR}/gradle
- ANDROID_HOME=${TRAVIS_BUILD_DIR}/android-sdk
- SDK=${TRAVIS_BUILD_DIR}/android-sdk
- PATH=${GRADLE_USER_HOME}/bin/:${SDK}/:${SDK}/tools/:${SDK}/platform-tools/:${PATH}
before_install:
- export OLD_SDK=/usr/local/android-sdk-24.0.2;
mkdir -p ${SDK};
cp -u -R ${OLD_SDK}/platforms ${SDK}/platforms;
cp -u -R ${OLD_SDK}/system-images ${SDK}/system-images;
cp -u -R ${OLD_SDK}/tools ${SDK}/tools

- platform-tools
- build-tools-23.0.2

- add-on
- extra
script:
- ./gradlew check
Use ls to confirm that the SDK path has not changed another time.
It's not currently necessary to move the SDK, and you need to update other things, perhaps add another tools after platform-tools, this code is outdated.

Travis CI throwing the firebase_cli_path. I am not sure how can I specify this path. In Google document, it mentioned that this path will automatically detect.
Well, then I need to install the firebase tools into Travis CI, How can I do that?
This is travis.yml
dist: trusty
branches:
only:
- master
before_install:
- gem install bundler
- bundle --version
- bundle install

# Uncomment the lines below if you want to

- sys-img-armeabi-v7a-android-17
script:
- bundle exec fastlane android uatrelease
after_success:
- firebase deploy --token $FIREBASE_TOKEN --non-interactive
This is fastfile
default_platform(:android)
platform :android do
desc "Runs all the tests"
lane :test do
gradle(task: "test")
end
desc "Submit a new Beta Build to Hockey App"
lane :beta do |options|
gradle(task: "clean assembleRelease")
firebase_app_distribution(
app: "1:***********************",
testers: "abc#gmail.com",
release_notes: "Configuring Fastlane",
firebase_cli_token:ENV["FIREBASE_TOKEN"]
)
end
end
I've figured out it and it's working now. Just included the script to install the standalone firebase tool in Travis.
Check this and add this
curl -sL firebase.tools | bash
in your travis.yml file.

I'm trying to set up my CI for a Android project that uses some C++ code. As such I need the NDK that doesn't come pre-installed on Travis Android images. I'm currently achieving this by pulling the NDK myself, however my CI box is complaining about the CMake license not being accepted. The weird thing is that I thought this was included in the android-sdk-license which I am already including in my build. My travis YAML looks like this:

The license error can be seen at the bottom of the build here
This is currently working for me:
install:
- echo y | sdkmanager 'ndk-bundle'
- echo y | sdkmanager 'cmake;3.6.4111459'
- echo y | sdkmanager 'lldb;3.0'
My .travis.yml is available here.
Looks like the NDK samples use travis, maybe look there to see what's missing from your build: https://github.com/googlesamples/android-ndk/blob/master/.travis.yml
I didn't try it but perhaps it's similar to the constraint library related issue.
As explained here and here, use a workaround to solve license issues or directly download it:
is there any solution without workaround using export license?
Yes, you can use the new sdkmanager to install the constraint library and accept the license:
- echo yes | sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout;1.0.2"
- echo yes | sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout-solver;1.0.2"
In your case, check the correct version for cmake like here and here, cmake;3.6.4111459:
- sdkmanager --list || true
- echo yes | sdkmanager "cmake;3.6.4111459"
Otherwise, the missing component will be detected by gradle and downloaded without accept it:
# Show version and download Gradle Wrapper if it's not already cached
- ./gradlew --version
# Clean project and download missing dependencies and components
- ./gradlew clean build
In that case, as explained here, you need to accept the license the first time via the workaround:
In your .travis.yml file add:
before_install:
- mkdir "$ANDROID_HOME/licenses" || true
- echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_HOME/licenses/android-sdk-license"
- echo -e "\n84831b9409646a918e30573bab4c9c91346d8abd" > "$ANDROID_HOME/licenses/android-sdk-preview-license"
Do not forgot to accept all the licences on the main android object:
android:
components:
# ...
licenses:
- android-sdk-license-.+
- '.+'
Before android script deprecation, you can accept all the licenses at the same time like this:
# THE SETUP STAGE

# If you comment out this section, Travis CI will install for you the components you define here.
# Check your project requirements and the components included by default on Travis-ci VM images.

# Check defaults: http://docs.travis-ci.com/user/languages/android/#Pre-installed-components
android:

# Check Android SDK Platform-tools: http://developer.android.com/tools/revisions/platforms.html

# - tools
# - platform-tools
# ...
licenses:
# Check licenses: http://docs.travis-ci.com/user/languages/android/#Dealing-with-Licenses
# By default Travis will accept all the licenses, but it's also possible to define a white list:
# White list current android-sdk-license revision.
# - 'android-sdk-license-5be876d5'
# White list all android-sdk-license revisions.
# - 'android-sdk-license-.+'
# White list all the licenses.
- '.+'
I think that if you remove licenses section, 'white list all the licenses' - '.+' is applied by default.
Before i write this question, i already search same question about this, they did export license because still use alpha version of constrain layout. But now android already release stable version of constrain layout. I tried a lot of setup but still failed..

Previous response: Since sdkmanager replaces android script
I'm a little outdated about Travis-ci and seems extra work is required now, so it's better you check:
As tir38 noticed, android tool is no longer supported. Instead, use sdkmanager...
Open issue and workarounds for this topic:
In your .travis.yml file add:
before_install:
- mkdir "$ANDROID_HOME/licenses" || true
- echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_HOME/licenses/android-sdk-license"
- echo -e "\n84831b9409646a918e30573bab4c9c91346d8abd" > "$ANDROID_HOME/licenses/android-sdk-preview-license"
Do not forgot to accept all the licences on the main android object:
android:
components:
# ...
licenses:
- android-sdk-license-.+
- '.+'
Another related issue and workaround:
If you are getting "Please install the missing components using the
SDK manager in Android Studio." error you can just install the missing
component with the sdkmanager command line tool:
echo y | sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout;1.0.0-beta4"
echo y | sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout-solver;1.0.0-beta"
This article explaining contraint-layout problem for Circle-ci and Travis-ci
Documentation about sdkmanager provided in the Android SDK Tools package (25.2.3+)
Outdated solution: Before android script deprecation
I don't use the default Travis-ci script to install Android components and accept licenses, from here:
# Install and update SDK
function install-and-update-sdk {
# Keep SDK packages up-to-date (only missing suggested updates are installed).
( sleep 5 && while [ 1 ]; do sleep 1; echo y; done ) | android update sdk -u -t \
${UPDATE_PKGS:-'platform-tools,tools,extra-android-m2repository,extra-google-m2repository'}
# Install or reinstall SDK packages (if empty, all packages are installed).
( sleep 5 && while [ 1 ]; do sleep 1; echo y; done ) | android update sdk -a -u -t \
${INSTALL_PKGS:-'build-tools-23.0.3,android-23'},${TARGET_PKGS:-}
}
You can accept all the licenses at the same time if you do it like this:
# THE SETUP STAGE

# If you comment out this section, Travis CI will install for you the components you define here.
# Check your project requirements and the components included by default on Travis-ci VM images.

# - 'android-sdk-license-.+'
# White list all the licenses.
- '.+'
The simplest solution that worked for me was to copy the SDK licenses to my project from SDK and then tell Travis to copy them to itself while building.
There's already a closed issue for this on Travis's Github page and one of the mentioned solutions on it is definitely working currently.
Solution
Copy the licenses folder found in Android SDK's root directory.
Paste it in the root directory of your own project on the same hierarchy where .travis.yml file is.
Add these commands to your .travis.yml's before_install block:
.travis.yml:
before_install:
- mkdir "$ANDROID_HOME/licenses" || true
- cp ./licenses/* "$ANDROID_HOME/licenses/"

I had the same issue and the problem was that I was using one old version of android build tools and gradle version, just updating them to the last version available did the trick.
For example, today the last version of gradle is 3.3, and build tools last version is 2.3.3.
My build.gradle file looks like that
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
}
}
This was raised as an issue some time ago https://issuetracker.google.com/issues/37102998
and if you go to last answers you will se that the issue was fixed by just upgrading gradle version and build tools version.
I am trying to set up Travis for Android. Running the build seems to work so far, but when it comes to the tests, it complains about "No connected devices!"

Can you tell me what I'm doing wrong and how to fix it?
Unfortunately i am not allowed to comment, as i just want to complete DominicJodoin's answer. Correct indentation and a longer ADB_INSTALL_TIMEOUT is necessary as DominicJodoin already stated.
In my opinion your Emulator is running but not ready to install an apk. With - adb wait-for-device you wait until the device connected. According to the Documentation this means:
Note that this command does not cause adb to wait until the entire system is fully booted. For that reason, you should not prepend it to other commands that require a fully booted system.
Try replacing this line with - android-wait-for-emulator in your travis.yml instead.

I think your problem is the sys-img-armeabi-v7a-android-22 image is not available yet on Travis CI.
Indeed if you run the following command on Travis CI: android list target, the output for android-22 shows no Tag/ABIs : no ABIs.
I would suggest you try running your tests on the sys-img-armeabi-v7a-android-21 in the meantime.
You can have a look at a sample Android project with unit tests I forked and ran successfully with your components but with sys-img-armeabi-v7a-android-21 image on Travis CI:

Hope this helps!
Edit: android-22 image should be available shortly on Travis CI. See the following pull request.
I wanted to use a more recent emulator. Unfortunately I wasn't able to make it work on android-26 or 27, but I was able to make it work on android-25. The ABI names were changed. Here's what works for me:

- EMULATOR_API_LEVEL=25
- ADB_INSTALL_TIMEOUT=8 # minutes (2 minutes by default)

I found the key ADB_TIMEOUT_INSTALL bit in J-Bossi answer, and it starts the emulator in before_script like Travis-CI is currently recommending, but I had issues with the VM running out of memory. So instead of running the emulator while the build is running, I changed my config to run the build, then start the emulator, then run the tests.
sudo: false

env:
global:
# switch glibc to a memory conserving mode
- MALLOC_ARENA_MAX=2
# wait up to 10 minutes for adb to connect to emulator
- ADB_INSTALL_TIMEOUT=10

I added the following configuration to run Travis CI on the Fahrplan Android project:
language: android
android:
components:
# All the build system components should be at the latest version
# - tools
# - platform-tools
- build-tools-21.1.1

jdk:
- oraclejdk7
- openjdk7
notifications:
email: true
before_script:
- chmod +x gradlew
- mv app/gradle.properties.example app/gradle.properties
script:
- ./gradlew clean assembleDebug
For some reason the process gets killed again and again as can be seen in the build history. It stops at different locations. The error message is not that informative:
The command "./gradlew clean assembleDebug" exited with 137
Only checking the gradle version you can force the download before you run the script (helps me to avoid error 137) but now i use wrapper so gradle-wrapper.jar is updated.
If it doesn't work, you can try to download the android dependencies before to run the script and clean before too.
I think they don't assemble by default but I like to override install stage to be sure.
In my case, error 137 is due concurrency (build/emulator) and jobs killed by Travis-ci. I solve it doing changes of this type and I don't understand it very well.
