동적 기능 모듈이 설치되지 않음

내 앱에 주문형 동적 기능 모듈을 추가하고 있는데 문제가 있습니다.

해당 기능 모듈을 설치할 때

val request = SplitInstallRequest.newBuilder()
    .addModule("ondemandfeature")
    .build()
splitInstallManager.startInstall(request)

다음 로그가 인쇄됩니다.

동적 기능 모듈이 성공적으로 설치되었다고 믿습니다. 하지만 설치된 모듈을 확인하려고 할 때 :

splitInstallManager.installedModules

빈 목록을 반환합니다.

내가 놓친 것이 있습니까?

추가 정보 :

다음은 로그입니다 SplitInstallStateUpdatedListener.

// begin
PENDING (printed 4x)
DOWNLOADING (printed 14x)
INSTALLING (printed 1x)
DOWNLOADED (printed 1x)
// end

나는 또한 INSTALLING로그 바로 뒤에 다음과 같은 것이 인쇄 되는 것을 감지했습니다 .

I/Finsky: [2] dyv.<init>(17): com.package.my is installed but certificate mismatch

무슨 뜻이에요?

추가 정보 2 :

Pixel 3XL (Android 10) 기기에서 주문형 동적 기능 모듈이 성공적으로 다운로드되고 설치됩니다.

그러나 Motorola G5 (Android 8.1) 장치에서는 주문형 동적 기능 모듈이 다운로드 만 가능하지만 설치되지는 않습니다.

추가 정보 3 :

어떤 이유로 다운로드 및 설치가 Android 10 장치에서만 작동하지만 이유를 모르겠습니다.

이 기능을 테스트하기 위해 앱 번들을 업로드 할 수 있는 내부 앱 공유 도구를 사용하고 있습니다 .
