ऐप खोले बिना Android नोटिफिकेशन एक्शन इम्प्लीमेंट करना

यह उदाहरण दर्शाता है कि ऐप खोले बिना Android नोटिफिकेशन एक्शन कैसे इम्प्लीमेंट किया जाता है।

चरण 1 - नया प्रोजेक्ट बनाएं

Android Studio में File → New Project पर जाएं और नया प्रोजेक्ट बनाने के लिए सभी आवश्यक विवरण भरें।

चरण 2 - res/layout/activity_main.xml में कोड जोड़ें

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="https://schemas.android.com/apk/res/android"
    xmlns:tools="https://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    tools:context=".MainActivity">
    <Button
        android:onClick="createNotification"
        android:text="create notification"
        android:layout_centerInParent="true"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</RelativeLayout>

चरण 3 - src/MainActivity.java में कोड जोड़ें

package app.tutorialspoint.com.notifyme;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.support.v7.app.AppCompatActivity;
import android.view.View;

public class MainActivity extends AppCompatActivity {
    public static final String NOTIFICATION_CHANNEL_ID = "10001";
    private final static String default_notification_channel_id = "default";

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

    public void createNotification(View view) {
        int NOTIFICATION_ID = (int) System.currentTimeMillis();
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, new Intent(), 0);
        Intent buttonIntent = new Intent(this, NotificationBroadcastReceiver.class);
        buttonIntent.putExtra("notificationId", NOTIFICATION_ID);
        PendingIntent btPendingIntent = PendingIntent.getBroadcast(this, 0, buttonIntent, 0);
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext(), default_notification_channel_id);
        mBuilder.setContentTitle("My Notification");
        mBuilder.setContentIntent(pendingIntent);
        mBuilder.addAction(R.drawable.ic_launcher_foreground, "Cancel", btPendingIntent);
        mBuilder.setContentText("Notification Listener Service Example");
        mBuilder.setSmallIcon(R.drawable.ic_launcher_foreground);
        mBuilder.setAutoCancel(true);
        mBuilder.setDeleteIntent(getDeleteIntent());
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            int importance = NotificationManager.IMPORTANCE_HIGH;
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "NOTIFICATION_CHANNEL_NAME", importance);
            mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
            assert mNotificationManager != null;
            mNotificationManager.createNotificationChannel(notificationChannel);
        }
        assert mNotificationManager != null;
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }

    protected PendingIntent getDeleteIntent() {
        Intent intent = new Intent(MainActivity.this, NotificationBroadcastReceiver.class);
        intent.setAction("notification_cancelled");
        return PendingIntent.getBroadcast(MainActivity.this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
    }
}

चरण 4 - src/NotificationBroadcastReceiver.java में कोड जोड़ें

package app.tutorialspoint.com.notifyme;
import android.app.NotificationManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class NotificationBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        int notificationId = intent.getIntExtra("notificationId", 0);
        NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        manager.cancel(notificationId);
    }
}

चरण 5 - AndroidManifest.xml में कोड जोड़ें

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
    package="app.tutorialspoint.com.notifyme">
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <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/AppTheme">
        <receiver
            android:name=".NotificationBroadcastReceiver"
            android:enabled="true"
            android:exported="true">
        </receiver>
        <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>

एप्लिकेशन चलाएं

अपने Android डिवाइस को कंप्यूटर से कनेक्ट करें। Android Studio से ऐप चलाएं और अपने मोबाइल डिवाइस पर डिफ़ॉल्ट स्क्रीन देखें।
