Declare Proguard rules for library

android {
    ...
    defaultConfig {
        ...
        consumerProguardFiles 'proguard-rules.pro'
    }
}

Manually build

./gradlew clean assembleDebug

Manually install apk

• ~/Library/Android/sdk/platform-tools/adb
• adb install [path to .apk]

Manually launch emulator

• ~/Library/Android/sdk/tools/emulator -avd Nexus_6_API_23 -netspeed full -netdelay none -http-proxy http://127.0.0.1:8888 -port 5554

Push to JCenter

Setup

Create local.properties at top level:

sdk.dir=/Users/alex/Library/Android/sdk
bintray.user=username
bintray.apikey=apikey
bintray.gpg.password=password

JCenter repo: https://bintray.com/[user]/maven/[repo name]

Push:

• For details see: https://inthecheesefactory.com/blog/how-to-upload-library-to-jcenter-maven-central-as-dependency/en
• Bump libraryVersion # in AndroidSDK/[app name]/build.gradle
• ./gradlew install
• Look for BUILD SUCCESSFUL
• ./gradlew bintrayUpload
• Look for BUILD SUCCESSFUL
• Run with --debug if anything goes wrong
• Check the JCenter repo to make sure the upload worked.

Test:

Install the new version of the library from JCenter in a new app and test that Gradle can sync and that everything works.

• Make sure the JCenter repo is configured in the new project's build.gradle:

allprojects {
    repositories {
        ...
        maven {
            ...
            url 'https://dl.bintray.com/[username]/maven/'
        }
    }
}

• Make sure the package is configured in the new project's app/build.gradle:

dependencies {
    ...
    compile '[package]:[artifact]:[version, e.g. 0.1.2]'
}

Clean gradle cache

• rm -rf ~/.gradle/caches
• rm -rf [ProjectRoot]/.gradle
• [ProjectRoot]/gradlew assemble
