Answer 1

Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app. If the device is running Android 6.0 or higher, and your app's target SDK is 23 or higher: The app has to list the permissions in the manifest, and it must request each dangerous permission it needs while the app is running. The user can grant or deny each permission, and the app can continue to run with limited capabilities even if the user denies a permission request.

To request permission in runtime, go to https://developer.android.com/training/permissions/requesting.html

Answer 2

Add runtime permission for access

Add library:
compile 'pub.devrel:easypermissions:0.2.1'

private String[] phonePermissions = {Manifest.permission.READ_PHONE_STATE};

if (EasyPermissions.hasPermissions(this, phonePermissions)) {
        //success
    } else {
        EasyPermissions.requestPermissions(this, "Access for Read Phone",
                101, phonePermissions);
    }
