# AdvancedPrivacy An app to let you control and protect your privacy. Forked to https://github.com/LedgerProject/e_privacycentralapp, embending all /e/ submodules. # Features The following features are currently part of AdvancedPrivacy app. 1. Centralized overview dashboard. 2. Fake location. 3. Hiding IP address. 4. Manage granular permissions. 5. Control trackers across apps. # Technologies - Kotlin as main language - Kotlin coroutines and flow for asynchronous code - AndroidX (core-ktx, fragment-ktx, and lifecycle etc.) - Google Material Design component for UI elements - Timber for logging - Room for database (may use datastore too) - Hilt for DI - MapBox for map support - LeakCanary for keeping an eye on memory leaks. - Junit for unit testing - Espresso for integration testing. - # Flavours This app comes in two flavours, one for /e/OS and second one for other android (where app doesn't have system access). For more information refer to [Architecture Guide](DEVELOPMENT.md) # Testing Need to write test and add code coverage. # Development ## Setup You can use any latest stable version of android studio to be able to build this app. ## Supported Versions - Minimum SDK: 24 (Android N) - Compile SDK: 30 (Android R) - Target SDK: 30 (Android R) ## API Keys This project uses [Sentry](https://sentry.io) for telemetry and crash reports, [Mapbox](https://docs.mapbox.com/android/maps/guides/install/) sdk for displaying maps. To download and use the mapbox sdk, you need to supply API key and secret and set them as follows: ### For local build You can set them in local.properties ``` MAPBOX_KEY= MAPBOX_SECRET_KEY= SENTRY_DSN= ``` **IMP: Never add this file to version control.** ### For CI build When building in CI environment, we don't have local.properties file. So the following environment variables must be set: ``` export MAPBOX_KEY= export MAPBOX_SECRET_KEY= export SENTRY_DSN= ``` ## Code Style and Quality This project uses [ktlint](https://github.com/pinterest/ktlint), provided via the [spotless](https://github.com/diffplug/spotless) gradle plugin. To maintain the same code style, all the codestyle configuration has been bundled into the project. To check for any codestyle related error, `./gradlew spotlessCheck`. Use `./gradlew spotlessApply` to autoformat in order to fix any code quality related issues. ### Setting up pre-commit hooks To strictly enforce the code quality, this project has a pre-commit hook which is triggered everytime before you commit any changes (only applies to *.kt, *.gradle, *.md and *.gitignore). You must setup the pre-commit hook before doing any changes to the project. For that, this project has a script which can executed as follows: ```bash hooks/pre-commit ``` ## Build dependencies TrackerFilter won't work unless your rom was build with this specific netd project: [android_system_netd](../../../e_privacycentral_android_system_netd) To create an /e/ build with this specific project, follow the documentation to create an usual /e/ build for your device https://doc.e.foundation/devices until `repo sync` After `repo sync` all the sources, replace ``` system/netd ``` with this repo [android_system_netd](../../../e_privacycentral_android_system_netd) then run the build as usual This won't include advanced privacy, you still need to build the app. This app requires different modules that must be built indivually and pushed to a local maven repository or our gitlab modules must be build and deployed in the following order: - privacymodule-api : - ./gradlew :privacymodule-api:assembleRelease - ./gradlew --console=verbose publishToMavenLocal // To make it available locally for dev. - ./gradlew --console=verbose publish // To publish it on gitlab for release. - [privacymodule-tor](../../../e_privacycentral_privacymoduletor) - [app] ## Build If you'd like to build AdvancedPrivacy locally, you should be able to just clone and build with no issues. For building from CLI, you can execute this command: ```bash ./gradlew build ``` ## How to use AdvancedPrivacy apk You can build the apk locally by using above instructions or you can download the latest stable apk from `master` branch pipeline. ### To run apk on /e/OS devices If you are running your tests on a `/test` build, the debug buildtype already sign it with the appropriate key, and without the persistant flag, to allow further updates. But the first time, to replace the AdvancedPrivacy app, embeded in the test build, you have to use the following commands: ```shell adb root && adb remount adb push your_advanced_privacy_debug_build.apk /system/priv-app/AdvancedPrivacy/AdvancedPrivacy.apk adb shell kill -9 $(adb shell pidof -s foundation.e.advancedprivacy) ``` #### AdvancedPrivacy requiement against the system AdvancedPrivacy needs to be installed as system app and whitelisting in order to grant some system specific permissions. Follow these steps to make it work properly on /e/OS 1. From `Developer options`, enable `Android debugging` and `Rooted debugging` 1. Sign the apk with platform certificate. You can use this command to do that ```shell apksigner sign --key platform.pk8 --cert platform.x509.pem AdvancedPrivacy.apk app-e-release-unsigned.apk ``` If you are running your tests on an `/test` build, you can find keys at https://gitlab.e.foundation/e/os/android_build/-/tree/v1-q/target/product/security 1. Install apk as system app and push permissions whitelist with following commands: ```shell adb root && adb remount adb shell mkdir system/priv-app/AdvancedPrivacy adb push AdvancedPrivacy.apk system/priv-app/AdvancedPrivacy ``` 1. Push permissions whitelist. - it requires the whitelisting [privapp-permissions-foundation.e.advancedprivacy.xml](privapp-permissions-foundation.e.advancedprivacy.xml) file that can be found in the project repository. - then use the following command ```bash adb push privapp-permissions-foundation.e.advancedprivacy.xml /system/etc/permissions/ ``` 1. Allow the fake location service to run in background. Add in the file /system/etc/permissions/platform.xml . 1. Reboot the device ```shell adb reboot ``` ### To run apk on stock android devices You can simply install the apk. Keep in that mind all features won't be available on stock android devices. > Voila !!!, AdvancedPrivacy is installed successfully in your device. # Distribution This project can be distributed as prebuilt apk with /e/OS or it can be published on other app stores for non /e/OS devices. # For developers and contributers Please refer to [Development Guide](DEVELOPMENT.md) for detailed instructions about project structure, architecture, design patterns and testing guide. # License ``` Copyright (C) 2021 ECORP This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
