Android Dependencies

app level

dependencies {
    compile 'com.android.support:appcompat-v7:25.3.1'
    // Access to Android Design library
    compile 'com.android.support:design:25.3.1'
    // Constraint layout
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    // Recycler view
    compile 'com.android.support:recyclerview-v7:25.3.1'
    // Image processing (Picasso)
    compile 'com.squareup.picasso:picasso:2.5.2'
    // View injector (Butter Knife)
    compile 'com.jakewharton:butterknife:8.5.1'
    // Gif views
    compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.7'
    // Progress button
    compile 'com.github.dmytrodanylyk.circular-progress-button:library:1.1.3'
    testCompile 'junit:junit:4.12'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'
    // Firebase
    compile 'com.google.firebase:firebase-core:10.2.6'
    compile 'com.google.firebase:firebase-auth:10.2.6'
    compile 'com.google.firebase:firebase-database:10.2.6'
    compile 'com.google.firebase:firebase-storage:10.2.6'
}

For use of Google Services, you also need

apply plugin: 'com.google.gms.google-services'

on the bottom of build.gradle in app folder.

build level

repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.2'
        // Google Services
        classpath 'com.google.gms:google-services:3.1.0'
    }

Android App Workflow

❗ We realized that Bluetooth Service could only be binded with one activity at a time near the end of the project timeline, so the way we handled BLE (simply binding and unbinding when switching activities) was not elegant. We strongly suggest you use fragments inside one activity to achieve the same functionality.
