Why is my camera intent working? I thought Nougat was supposed to fix this security issue?

Question

Everything I'm seeing says that you need to add a <provider> section into the AndroidManifest, and you need to refer to an XML resource file that says the external file path you want for the image.

I'm doing neither of those but the code snippet I found is working, even on Nougat and newer.

I'm wondering why. I can't figure out what is causing this to actually work.

Here is my Android manifest:

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

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

And here is the full MainActivity. I would love to trim it down quite a bit for you guys but I want to make sure I don't accidentally cut something out that you guys need to see. I can't figure it out.

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private static final int REQUEST_TAKE_PHOTO = 1;

    Button btnTakePhoto;
    ImageView ivPreview;

    String mCurrentPhotoPath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        initInstances();
    }

    private void initInstances() {
        btnTakePhoto = (Button) findViewById(R.id.btnTakePhoto);
        ivPreview = (ImageView) findViewById(R.id.ivPreview);

        btnTakePhoto.setOnClickListener(this);
    }
