And by the way: Cliqz is free and open source.

Cliqz features at a glance:

  • Maximum privacy
  • Innovative quick search
  • Ad blocker
  • Phishing protection
  • Forget mode
  • Cliqz Tab with most visited websites and news

How to clone and start hacking

Run these commands in a shell:

$> git clone git@github.com:cliqz-oss/browser-android.git
$> cd browser-android

Once the repository is checked out, get the dependencies for the react-native bundle, and build it

$> npm ci
$> npm run dev-bundle

You can compile the project using the the gradle wrapper on the command line:

$> ./gradlew :app:assembleCliqzDebug

Please notice you have to have the Android SDK. On Mac OSX, the latter can be installed using brew:

$> brew install android

Signing for distribution (CLIQZers only)

The APK must be signed to be published on PlayStore, for more information follow this link. To sign the app you need the CLIQZ keystore, however it is not and must not be distributed with the source code, also keystore passwords must be kept secret. If you have the keystore and the passwords, you can configure gradle to generate the signed APK. To do so, create a gradle.properties file and add (or append to it if already exists) the following lines:

Browser.storeFile=<key_store_path>
Browser.storePassword=<key_store_password>
Browser.keyAlias=<key_alias>
Browser.keyPassword=<key_password>

Replace <param> with the appropriate arguments, then you can compile the release APK using the usual gradle tasks (:app:assembleCliqzRelease).

React Native Development

The project uses react-native for some logic and views. This code is developed in the browser-core repository. To debug these components, follow these steps:

  1. Set the developer support flag for the JSEngine: https://github.com/cliqz/android-browser/blob/master/app/src/main/java/com/cliqz/jsengine/Engine.java#L42
  2. Start the react-native dev server:
npm run dev-server

Now, if the app is run, the JS code will be loaded from the dev server. In addition react-native debugging options will be available under the 'React Native Debug' option in the settings menu. If opened in the Chrome debugger, the app object (the root for all modules from browser-core will be exposed in the web-worker context.

To also develop code from browser-core, follow these steps:

  1. Check out browser-core somewhere (Cliqzers use navigation-extension)
  2. In the browser-core/navigation-extension directory, get dependencies to build the extension.
./fern.js install
  1. Now, build the extension, and direct the build output to the android browser's node_modules directory. Use the fern serve command means that the project will be rebuild if you make code changes:
 CLIQZ_OUTPUT_PATH=/path/to/android-browser/node_modules/browser-core/build/ ./fern.js serve configs/cliqz-android.js

Now the dev server will see and load the updated files outputed from the fern build when you reload the code in the app.

Debugging

To work with react live reloading server, the Developer Support option has to be set on ReactInstanceManager in /app/src/main/java/com/cliqz/jsengine/Engine.java, using .setUseDeveloperSupport(true).

Then Android has to be asked for system overlay permission to show React Native debug menu. One way to ask for this permission is with adb:

adb shell am start -a android.settings.action.MANAGE_OVERLAY_PERMISSION -d package:com.cliqz.browser.debug

Application will automatically detect if react dev server is running and will load bundle from it, otherwise the bundle will be loaded from app assets.
