_A collection of Android libraries to build browsers or browser-like applications._

ℹ️ For more information **[see the website](https://mozilla-mobile.github.io/android-components/)**.

A fully-featured reference browser implementation based on the components can be found in the [reference-browser repository](https://github.com/mozilla-mobile/reference-browser).

# Maven repository

All components are getting published on [maven.mozilla.org](https://maven.mozilla.org/).

To use them, you need to add the following to your project's top-level build file, in the `allprojects` block (see e.g. the [reference-browser](https://github.com/mozilla-mobile/reference-browser/blob/main/build.gradle)):

```groovy

repositories {

    maven {

       url "https://maven.mozilla.org/maven2"

    }

}

```

Each module that uses a component needs to specify it in its build file, in the `dependencies` block.  For example, to use the `Base` component (in the `support`) collection, you need:

```groovy

dependencies {

    implementation 'org.mozilla.components:support-base:+'

}

```

## Nightly builds

Nightly builds are created every day from the `main` branch and published on [nightly.maven.mozilla.org](https://nightly.maven.mozilla.org).

# Building #

## Command line ##

```

$ git clone https://github.com/mozilla-mobile/android-components.git

$ cd android-components

$ ./gradlew assemble

```

## Android Studio ##

If the environment variable `JAVA_HOME` is not defined, you will need to set it. If you would like to use the JDK installed by Android Studio, here's how to find it:

1. Open Android Studio.

2. Select "Configure".

3. Select "Default Project Structure". You should now see the Android JDK location.

4. Set the environment variable `JAVA_HOME` to the location. (How you set an environment variable depends on your OS.)

5. Restart Android Studio.

Once the environment variable is set, you can import the project into Android Studio with the default wizard options.

If your build fails, you may find you get more instructive error messages by attempting the build at the command line.

# Coding Standards #

## Style ##

We follow the style enforced by [ktlint](https://ktlint.github.io/) and [detekt](https://arturbosch.github.io/detekt/). See [how to configure Android Studio appropriately](https://github.com/pinterest/ktlint#option-1-recommended).

To check your style, run:

```

./gradlew ktlint

./gradlew detekt

```

## Documentation ##

We use `README.md` files for each component.

If you fix a bug or change an API, you should update [docs/changelog.md](https://github.com/mozilla-mobile/android-components/blob/main/docs/changelog.md).

## Testing ##

You are expected to both add tests for code that you write and make sure that your changes do not

cause existing tests to fail. You may find these command lines helpful:

```

./gradlew test                             # Run all tests

./gradlew :support-ktx:testdebugunittest   # Run unit tests for a specified module

```

See also [how to measure code coverage](https://mozac.org/contributing/code-coverage).

## Accessibility ##

If your code has user-facing changes, follow [Android accessibility best practices](https://github.com/mozilla-mobile/shared-docs/blob/main/android/accessibility_guide.md).
