README

Android Instant Apps - Sample code collection

The samples in this repository demonstrate building and using APIs related to Android Instant Apps.

Getting started

Shared instructions on the samples are collected in this file. For sample specific instructions, enter a sample's directory and follow the corresponding README file.

Available samples

analytics -> Usage of Firebase Analytics

configuration-apk -> Introduces Configuration APKs

cookie-api -> Usage of the Cookie API

hello-java -> Hello World written in the Java Programming Language.

hello-kotlin -> Hello World written in Kotlin.

hello-feature-module -> Hello World with feature modules

install-api -> Introduces Install API

multi-feature-module -> More complex feature module sample

flavors -> product flavors in an Instant App

Running an Instant App sample

From Android Studio

1. Select the instant feature module run configuration
2. Run the selected configuration

Some samples provide multiple entry points. In this case you can choose which URL to use before starting the Instant App.

From the command line (Android O+)

Find the build output

1. Run a gradle build ./gradlew assembleDebug.
2. Locate the zip file containing the instant app. 2.1 This is usually located at ./instant/build/outputs/debug/instant-debug.zip 2.2 Some samples contain flavors. In these cases the output path is different. These build output paths will be specified in the sample in question.

Run the Instant App

From the sample's root directory, execute

nstant/build/outputs/apk/debug # navigate to build dir
p instantapp-debug.zip # extract apks
install-multiple -r -t --instantapp *.apk # install apks

unch entry point; you'll have to replace $(SAMPLE_ENTRY_POINT)
shell am start -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d $(SAMPLE_ENTRY_POINT)

 # takes you back to the root directory

Code minification & obfuscation

Each sample's minified build type has code minification enabled. In case API surfaces are being exposed to other modules, these surfaces are being explicitly excluded from the obfuscation process through a proguard configuration file. Take a look in a module's build.gradle file to see what is being done for that module.

Usage

From Android Studio

• Open Build Variants
• Change each variant to a “minified” variant
• Run the “instant” configuration of the sample

From the command line

• Assemble a minified build ./gradlew assembleMinified
• Navigate to instant/build/outputs/apk/*/minified
• Run the instant app as described in the above section

Note: For samples containing flavors the paths & variant names will be slightly different.

Troubleshooting

Refer to the troubleshooting section of the Android Instant Apps documentation.
