SLicense Crowdin Build Status Codacy Badge GitHub release

Note taking open-source application aimed to have both a simple interface but keeping smart behavior.

The project was inspired by the absence of such applications compatible with old phones and old versions of Android. It aims to provide an attractive look and follow the most recent design guidelines of the Google operating system.

Watch the following terminal session recording on how to compile distributable files asciicast

To be sure that build environment is fully compliant with the project the following command creates a container with all the needed tools to compile the code:

cd {project-folder}; rm local.properties; docker rm android; docker run -v $PWD:/workspace --name android tabrindle/min-alpine-android-sdk:latest bash -c "yes | sdkmanager --update && yes | sdkmanager --licenses && cd /workspace && ./gradlew build --stacktrace -Dorg.gradle.daemon=true -Pandroid.useDeprecatedNdk=true"


To execute all tests included into the project connect a device or emulator, then run the following command:

./gradlew connectedAndroidTest


Due to the fact that I’m using gitflow as code versioning methodology, you as developer should always start working on develop branch that contains the most recent changes.

There are many features/improvements that are not on my roadmap but someone else could decide to work on them anyway: hunt for issues tagged as Help Wanted to find them!

Feel free to add yourself to contributors.md file.

New feature or improvements contributions

This kind of contributions must have screenshots or screencast as demonstration of the new additions.

Code style

If you plan to manipulate the code then you’ll have to do it by following a specific code style. Also pay attention if you’re using any plugin that automatically formats/cleans/rearrange your code and set it to only change that code that you touched and not the whole files.

Test your code contributions!

All code changes and additions must be tested. See the related section for more informations or this two pull requests comments: one and two

Forking project

When forking the project you’ll have to modify some files that are strictly dependent from my own development / build / third-party-services environment. Files that need some attention are the following:

Code quality

A public instance of SonarQube is available both to encourage other developers to improve their code contributions (and existing code obviously) and to move the project even further into transparency and openness.

Checkout for it here

Pull requests will be automatically analyzed and rejected if they’ll rise the code technical debt.


They’re all listed into the build.gradle file but due to the fact that many of the dependences have been customized by me I’d like to say thanks here to the original developers of these great libraries:
