Androidx Camera: Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 21

Hi I am using CameraX api to build custom camera, after adding updated library dependency to build.gradle file, i am getting following build error

Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [androidx.camera:camera-extensions:1.0.0-alpha08] /Users/.gradle/caches/transforms-2/files-2.1/f20dc98c605a4c4dbd6030601f9665d3/camera-extensions-1.0.0-alpha08/AndroidManifest.xml as the library might be using APIs not available in 16 Suggestion: use a compatible library with a minSdk of at most 16, or increase this project's minSdk version to at least 21, or use tools:overrideLibrary="androidx.camera.extensions" to force usage (may lead to runtime failures)

build.gradle file

You can stick to your minimum version 16 by adding the following to your manifest file.

<uses-sdk tools:overrideLibrary="androidx.camera.view, androidx.camera.camera2, androidx.camera.lifecycle, androidx.camera.core"/>

To avoid runtime failures you'll need to check if the device is running on api 21 and above before using CameraX

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
        // Use camera2 or cameraX
}else{
        // Use Camera1
}
