How to set broadcast receiver attributes programmatically in android studio?

[priyamtheone]

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 programmaticall y 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:exporte d="false". I need to know, how do I specifically set these two attributes when I register the receiver programmaticall y?

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.ja va 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 MyBroadcastRece iver.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();
    }
}

Studying further revealed the fact that there isn't any Java code counterpart for those two XML attributes. If you register the BroadcastReceiv er it is enabled. If you unregister it, it is disabled. Those attributes are only relevant for manifest-registered receivers. If you dynamically register a BroadcastReceiv er, it will be triggered based on the IntentFilter that you specify. If you want to prevent your BroadcastReceiv er from being triggered by other apps, you can use LocalBroadcastM anager for that.
