install-api -> Introduces Install API
multi-feature-module -> More complex feature module sample
flavors -> product flavors in an Instant App
urlless -> An instant app sample that doesn't require URL association.
Running an Instant App sample
From Android Studio
- Select the
instantfeature module run configuration
- 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
- Run a gradle build
- Locate the zip file containing the instant app.
2.1 This is usually located at
./instant/build/outputs/debug/instant-debug.zip2.2 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
cd instant/build/outputs/apk/debug # navigate to build dir unzip instantapp-debug.zip # extract apks adb install-multiple -r -t --instantapp *.apk # install apks # launch entry point; you'll have to replace $(SAMPLE_ENTRY_POINT) adb shell am start -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d $(SAMPLE_ENTRY_POINT) cd - # takes you back to the root directory
Code minification & obfuscation
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.
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
- Navigate to
- Run the instant app as described in the above section
Note: For samples containing flavors the paths & variant names will be slightly different.
Refer to the troubleshooting section of the Android Instant Apps documentation.
