Answer 1

This is a bug in the current implementation of Google Play Services support of instant apps.

It will be fixed in a future release, at which point the android.hardware.Camera API should function correctly.

Unfortunately I don't have any specifics on the timeframe of the fix being available.

Answer 2

Instant apps run natively on Android O and on previous versions, they use google play services to run. So camera 1 is not supported in instant apps prior to API 26 as they don't run natively. However, you can use Camera 1 api in an instant app on API 26 and till the time Camera 1 api lives I would imagine.

However, I'm using camera 2 api in the instant app and camera 1 api in the installed app.

Answer 3

android.hardware.Camera was deprecated in API level 21, while Instant Apps support devices only from API level 23. You need to use android.hardware.camera2 instead.

https://developer.android.com/reference/android/hardware/camera2/package-summary.html

The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.

This issue was addressed in https://issuetracker.google.com/issues/38485484 where Engineers provided the following information:

"Instant apps don't support the old deprecated android.hardware.Camera. They only support the camera2 APIs"

Answer 4

Instant apps have restricted functionality, obviously that method is not supported. You can use InstantApps.isInstantApp() method to determine whether it is installed or instant app and call isCameraSoundForced only for installed.
