FAQs

Cannot open camera on Android 9 and Android 10 devices?

Cause: On Android 9 and Android 10, requesting USB permissions will also check for Camera permissions. However, due to an anomaly in the Android framework, even if Camera permissions are granted, the check still fails, preventing USB permissions from being granted.
Solution: Modify the app's targetSdkVersion to 27 or lower.
defaultConfig { targetSdkVersion 27 }
