Bloody Health Cycle Tracker
A menstrual cycle tracking app that's open-source and leaves your data on your phone. Use it to track your menstrual cycle and/or for fertility awareness!
Development setup
-
Install Android Studio - you'll need it to install some dependencies.
-
Make sure you are running Node 8 or 9 (newer versions won’t work). It's easiest to switch Node versions using
nvm
, here’s how to do it:curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash nvm install v9
-
Clone this repository:
git clone git@gitlab.com:bloodyhealth/drip.git cd drip
-
Open Android Studio and click on "Open an existing Android Studio project". Navigate to the drip repository you cloned and double click the android folder. It detects, downloads and cofigures requirements that might be missing, like the NDK and CMake to build the native code part of the project. Also see the nodejs-mobile repository for the necessary prerequisites for your system.
-
Either start a virtual device in Android Studio or set your physical device like your Android phone up to run the app.
-
Open a terminal and run
npm install
-
Run
npm run android
-
In another tab, run
npm run log
to see logging output -
Run
adb shell input keyevent 82
and select enable hot reloading (see https://facebook.github.io/react-native/docs/debugging.html) -
We recommend installing an ESLint plugin in your editor. There's an
.eslintrc
file in this project which will be used by the plugin to check your code for style errors and potential bugs.
Java problems on macOS
Make sure that you have Java 1.8 by running java -version
.
If you don't have Java installed, or your Java version is different, the app may not work. You can try just using Android Studio's Java by prepending it to your $PATH
in your shell profile:
```
export PATH="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home/bin:${PATH}"
```
Now, which java
should output /Applications/Android Studio.app/Contents/jre/jdk/Contents/Home/bin/java
, and the correct Java version should be used.
Windows problems
Unfortunately, the react native version we use doesn't work on Windows 10 it seems, find more info here.
Tests
You can run the tests with npm test
.
Debugging
In order to see logging output from the app, run npm run log
in a separate terminal.
