talks about overlay permission.

They add the permission check code to the activity which hosts react native view.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    if (!Settings.canDrawOverlays(this)) {
        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                                   Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
    }
}

It seems the permission is required because react native needs to show the debug window in an overlay.

How to turn it off in production build?

I turned it off in release with two changes, one in the manifest, and one in the code.

First: In your main Manifest (src/main/AndroidManifest.xml), remove the line:

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

Add a new manifest in src/debug/AndroidManifest.xml that looks like this

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.mycompany.myapp">

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

This will merge the permission only on debug variants.

Second, to the code you mentioned, I added a check for BuildConfig.DEBUG:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    if (!Settings.canDrawOverlays(this) && BuildConfig.DEBUG) {
        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
    }
}
