Simple

An Android app for recording blood pressure measurements.

Pre-requisites

The application currently requires JDK 1.8 to build. If you already have JDK 1.8 installed, skip this step.

Check if the right JDK is already available

Run the command

java -version

sh
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_232-b09)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.232-b09, mixed mode)

If this command has an error, or shows a different version, you can follow the instructions below to install the JDK.

Install the JDK

We recommend using jEnv to manage your JDK installations. Here are instructions to setup a working JDK 1.8 installation (macOS only):

1. Setup up Homebrew.

2. Install

   jEnv

   using Homebrew.

   sh
   brew install jenv
   

3. Add the following lines to your shell configuration file (

   ~/.bash_profile

   if you're using bash, or

   ~/.zshrc

   if you're using zsh).

   sh
   export PATH="$HOME/.jenv/bin:$PATH"
   eval "$(jenv init -)"
   

4. Once this is done, you'll need to restart the terminal or reload the configuration file in order for the

   jenv

   command to be recognised.

   sh
   source 
   

5. Install the JDK using Homebrew.

   sh
   brew tap AdoptOpenJDK/openjdk
   brew cask install adoptopenjdk8
   

6. Add the installed JDK to

   jEnv

   sh
   jenv add /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home
   

7. Run the command

   jenv versions

   . You should see something like:

   sh
   system
   * 1.8
   1.8.0.222
   

How to build

Clone the project using git.

Run the following command in a terminal.

 $ git clone [email protected]:simpledotorg/simple-android.git

Install Android Studio

Download and install Android Studio from their website.

Import the project into Android Studio.

When Android Studio starts up, it will prompt you to create a new project or import an existing project. Select the option to import an existing project, navigate to the

simple-android

When building for the first time, gradle will download all dependencies so it'll take a few minutes to complete. Subsequent builds will be faster.

Running locally

The Simple App can be run locally on an Android emulator using Android Studio. To do this,

Install the NDK library

The NDK library is currently required by the project to enable an SQLite extension. To install it:

• Open the SDK Manager through Tools -> SDK Manager
• Select Appearance & Behavior -> System Settings -> Android SDK in the left sidebar
• Select the SDK Tools tab in the main window
• Activate NDK (Side by Side) and click Apply

NDK will now be installed.

Create a Run/Debug configuration

• Open the Run/Debug configurations window through Run -> Edit Configurations (ref)
• Create a new configuration using the

  Android App

  template
• Set the module to

  app

  , and finish creating the configuration

Create a virtual device

• Create an Android Virtual Device (AVD) using the AVD Manager, usually found in Tools -> AVD Manager. (ref)
• Select a device and operating system
• Note: You will have to download one of the available OS options the first time you create an AVD

Set the right build variant

• Open the Build Variants window through View -> Tool Windows -> Build Variants, or clicking the item in the lower left corner of the main window
• Set the Build Variant of the app module to

  qaDebug

Run the app

• Click "Run", either through Run -> Run, or the green play button in the top toolbar.

Code styles

The code styles which the project uses have been exported as an IntelliJ code style XML file and are saved as

quality/code-style.xml

1. Open the Android Studio preferences page, and navigate to Editor -> Code Style.
2. Click on the gear/settings button next to the "Scheme" label.
3. In the drop-down menu, select "Import scheme".
4. In the file picker, navigate to

   /quality/code-style.xml

   .
5. Import the

   Simple

   scheme into the IDE and set it as the project code style.
