Please use import android.os.Build.VERSION.SDK_INT and directly refer to SDK_INT (to not confuse with the Build from device profiles.
Also please use direct SDK level code (31) instead of named version codes.

Done, updated in the latest commit.
- Add USER_ACTION_NOT_REQUIRED to SessionParams in installPackagesInternal() for API 31+ (Android 12+) to prevent Huawei EMUI InstallDistActivity from intercepting every PackageInstaller session commit with a confirmation dialog. - Implement splitDeferred() in SplitInstallService to route deferred DFM install requests through splitInstallFlow() instead of being a no-op stub. Previously, apps like Facebook would fall back to startInstall() for each deferred module, triggering additional PackageInstaller sessions and additional InstallDistActivity dialogs on EMUI. Fixes: microg#3541

@mar-v-in I've updated the SDK_INT import and switched to the direct API level (31) as requested. Ready for another look whenever you have time, please let me know if anything else needs changing. |

Fixes #3541
When an app installed through microG requests dynamic feature modules, microG asks for an install confirmation again and again.
splitDeferred()was a no-op stub, so apps such as Facebook never got an answer and fell back tostartInstall()for the same modules. Every request created a newPackageInstallersession that needed a confirmation:InstallDistActivityon Huawei EMUI,PackageInstallerActivityon stock Android.As a side benefit, the same change removes the confirmation on stock Android 12+ for apps updated through the installer proxy (#3074), for example Aurora Store's "Update all" with the microG installer.
Changes
SplitInstallService.kt: implementsplitDeferred()through the samesplitInstallFlow()asstartInstall(), and always callonDeferredInstall()afterwards so the caller is not left waiting.Install.kt: setUSER_ACTION_NOT_REQUIREDon the session forSDK_INT >= 31.AndroidManifest.xml: requestUPDATE_PACKAGES_WITHOUT_USER_ACTION(normal permission, API 31+). Without it, Android ignoresUSER_ACTION_NOT_REQUIRED(PackageInstallerSession.computeUserActionRequirement).Security considerations
