However, if you lot hit bring issues, you lot tin ever revert to DX for right away via this setting inwards your project's gradle.properties file:

android.enableD8=false 

If you lot hit run into something that causes you lot to disable D8, delight let us know!

Next Steps

Our destination is to ensure that everyone has access to a fast, right dex compiler. So to avoid risking regressions for whatever of our users, we'll live on deprecating DX inwards 3 phases

The laid about stage is intended to forestall prematurely deprecating DX. During this phase, DX volition rest available inwards studio. We'll create critical issues inwards it, only in that place won't live on novel features. This stage volition finally for at to the lowest degree 6 months, during which we'll evaluate whatever opened upwards D8 bugs to create upwards one's hear if in that place are regressions which would forestall roughly users from replacing DX alongside D8. The laid about stage won't terminate until the squad addresses all migration blockers. We'll live on paying extra attending to the põrnikas tracker during this window, in addition to thence If you lot run into whatever of these regressions, delight file an issue.

Once we've seen a 6 calendar month window without major regressions from DX to D8, we'll move into the minute phase. This stage volition finally for a year, in addition to is intended to ensure that fifty-fifty complex projects bring lots of fourth dimension to migrate. During this phase, we'll hold DX available, only we'll process it equally fully deprecated; nosotros won't live on fixing whatever issues.

During the 3rd in addition to concluding phase, DX volition live on removed from Android Studio. At this point, you'll necessitate to role a legacy version of the Android Gradle Plugin inwards gild to buy the farm on to construct alongside DX.

Android Android Studio Google Play Requirements

Posted yesteryear Tom Greenaway, Senior Partner Developer Advocate

Last yr nosotros announced that starting from August 2018 Google Play volition require all new apps in addition to games to target a recent Android API score – laid to API score 26 (Android 8.0 Oreo), or higher. Additionally, this requirement volition extend to updates for existing apps in addition to games starting from Nov 2018.

Every novel Android version introduces changes that convey meaning safety in addition to functioning improvements – in addition to heighten the user sense of Android overall. Updating your games to target the latest API score ensures that your users tin create goodness from these improvements, land notwithstanding allowing your games to run on older Android versions.

Simple side yesteryear side steps:

• Install the Android 8.0 Oreo SDK (API score 26) via Android Studio yesteryear navigating to (Tools > Android > SDK Manager > Android SDK > SDK Platforms).
• Update your game to target API score 26 in addition to run into whether your game has whatever incompatibilities or issues as presently equally possible. Update whatever external dependencies equally necessary. Learn to a greater extent than close the incremental changes between versions of Android here.
• If you lot are using an advertising network, SDK or plugin which is incompatible amongst API score 26, accomplish out to your contacts in addition to discovery out their timeline for supporting target API score 26. The sooner they're aware of these changes the better.
• If you lot ready your game amongst Unity, back upwardly for target API 26 is built into Unity 5.6.6 in addition to beyond. Simply ensure the latest target API score is selected inward your Android ready settings for Unity (Build Settings > Android > Player Settings).
