How to set broadcast receiver attributes programmatically?

I'm broadcasting an intent in my app and receiving it with a broadcast receiver. I can handle the broadcasting and receiving. No problem with that. However, I want to register the receiver completely programmatically instead of doing it in the manifest file. Notice, that in the manifest file, there are two attributes of the receiver android:enabled="true" and android:exported="false". I need to know, how do I specifically set these two attributes when I register the receiver programmatically?

My AndroidManifest.xml file:

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

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

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android:name=".MyBroadcastReceiver"
            android:enabled="true"
            android:exported="false">
        </receiver>
    </application>

</manifest>

My MainActivity.java file:

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    MyBroadcastReceiver myReceiver;
    IntentFilter intentFilter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        myReceiver = new MyBroadcastReceiver();
        intentFilter = new IntentFilter();
        intentFilter.addAction("com.example.mybroadcastapplication.EXPLICIT_INTENT");
        findViewById(R.id.button1).setOnClickListener(this);
    }

    public void broadcastIntent() {
        Intent intent = new Intent();
        intent.setAction("com.example.mybroadcastapplication.EXPLICIT_INTENT");
        getApplicationContext().sendBroadcast(intent);
    }

    @Override
    protected void onPostResume() {
        super.onPostResume();
        registerReceiver(myReceiver, intentFilter);
    }

    @Override
    protected void onStop() {
        super.onStop();
        unregisterReceiver(myReceiver);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button1:
                broadcastIntent();
                break;
            default:
        }
    }
}

My MyBroadcastReceiver.java file:

public class MyBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction() != null && intent.getAction().equals("com.example.mybroadcastapplication.EXPLICIT_INTENT"))
            Toast.makeText(context, "Explicit intent received.", Toast.LENGTH_LONG).show();
    }
}

You don't need to declare the BroadcastReceiver in the manifest if you are registering/unregistering programmatically. You only need to declare BroadcastReceivers in the manifest if you want them to be instantiated from external triggers (for example, on device boot, or from the Alarm Manager, etc.)
