Final 12 months, we launched Android App Bundles and Google Play Dynamic Supply to introduce modular growth, scale back utility dimension, and simplify the publishing course of. Since then, builders have shortly adopted this new utility mannequin in additional than 60,000 manufacturing purposes. We’re happy to see that builders are reaching vital financial savings in utility dimension and decreasing the time required to handle every launch. We’ve got additionally documented these advantages in case research with Duolingo and RedBus.

Thanks to everybody who took the time to share their suggestions on our preliminary launch. We’re at all times open to new concepts and right this moment we’re joyful to announce new enhancements based mostly in your recommendations:

If a person modifications the locale of the system after the set up of the applying, Play robotically downloads the required sources.

Some builders select to decouple the applying show language from the system locale by including a built-in language selector to the applying. With the most recent model of the Play Core Library (model 1.four.zero), we introduce a brand new, further language API that means that you can create in-application language selectors whereas retaining all the advantages of smaller installations offered to utilizing bundles of purposes.

With the extra language API, purposes can now ask the Play Retailer to put in sources for a brand new on-demand language configuration and begin utilizing it instantly.

installRequestBuilder.addLanguage (Locale.forLanguageTag ("pl"))
splitInstallManager.startInstall (installRequestBuilder.construct ())

The appliance may also monitor the success of the set up with reminders and monitor the obtain standing with a listener, corresponding to when requesting an on-demand module.

Don’t forget to handle the state SplitInstallSessionStatus.REQUIRES_USER_CONFIRMATION. Observe that a current API change has been made in a current model of Play Core, which signifies that it’s essential to use the brand new SplitInstallManager # startConfirmationDialogForResult () with Exercise # onActivityResult (). The earlier technique of utilizing SplitInstallSessionState # resolutionIntent () with startIntentSender () was deprecated.

Everlasting uninstallation of the set up modules
