來使用AppBundle吧！

What is App Bundle

Google Play’s new app serving model, called Dynamic Delivery, to generate and serve optimized APKs for each user.

More details
.aab is compressing file like .zip, and it contains ProtoBuffer formate files.

Generation of result types

• Base APK
  the main part of your application.
• Configuration APKs
  the native libraries(.so) and resources for a specific screen density, CPU architecture, or language.
• Dynamic feature APKs
  the dynamic modules, which can download and install by calling APIs in the Play Core Library from the Google Play Store.

How to test

Test how Google Play uses .aab to generate APKs and how those APKs behave when deployed to a device.

1. locally using the bundletool command line tool.
2. uploading your bundle to the Play Console and using a test track.

Test 1 : BundleTool

setup

1. download bundleTool file .jar or source code(it will need build by yourself)
2. set up the environment variable, $ANDROID_HOME, to your Android/sdk path

edit file .bash_profile like this
localhost$ vim ~/.bash_profile
localhost$ source ~/.bash_profile
localhost$echo $ANDROID_HOME

generate apks

3. generate APK set for all device configurations you wnat support.
   unsigned APKs :
   $ java -jar /Users/deer/Documents/tool/bundletool.jar build-apks --bundle=/MyApp/my_app.aab --output=/MyApp/my_app.apks
   signed APKs :
   $ java -jar /Users/deer/Documents/tool/bundletool.jar build-apks --bundle=/MyApp/my_app.aab --output=/MyApp/my_app.apks
   --ks=/MyApp/keystore.jks --ks-pass=file:/MyApp/keystore.pwd
   --ks-key-alias=MyKeyAlias --key-pass=file:/MyApp/key.pwd

install apks

3. connect your device by USB

4. use the command in android studio Terminal, like this:
   $ java -jar /path1/tool/bundletool.jar install-apks --apks=/path2/project/app/build/outputs/bite.apks
   * path1 is your bundletool.jar path, path 2 is the apks
   more:
   you can set the java -jar /path2/tool/bundletool.jar to
   alias command bundletool.
