How get permission for camera in android Specifically Marshmallow

Question

Hello, I'm creating an Android app in Android Studio. I need the camera's consent in that situation. The AndroidManifest.xml file contains the code 

<uses-permission android:name="android.permission.CAMERA" />

With the exception of Marshmallow, it functions correctly on all versions of Android. How can I automatically receive camera permission? If that's not possible, how can I ask the user?

Answer 1

To begin with, confirm that the user has given the permission:

if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
    == PackageManager.PERMISSION_DENIED)

Then, you might employ this to ask the user to:

ActivityCompat.requestPermissions(activity, new String[] {Manifest.permission.CAMERA}, requestCode);

Additionally, it will pop up in a dialogue in Marshmallow.
