NotificationCompat.Builder() not accepting Channel Id as argument

Question

I know this question has been asked several times before. But none of the solutions worked for me. That's why I would like to ask the question again. The following line only accepts NotificationCompat.Builder(context) :

 NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, ADMIN_CHANNEL_ID)  // Getting error

I have fulfilled:

• importing android.support.v4.app.NotificationCompat

• My support libraries version is above 25

  implementation group: 'com.android.support', name: 'appcompat-v7', version: '27.1.1'

• Compile & Target sdk is above 25

  android { compileSdkVersion(27) buildToolsVersion '27.0.3' flavorDimensions 'default' dataBinding { enabled = true } defaultConfig { applicationId('something') minSdkVersion(16) targetSdkVersion(27) versionCode(1) versionName('1.0.0') testInstrumentationRunner('android.support.test.runner.AndroidJUnitRunner') multiDexEnabled true } But still getting the error. What should I do to fix this? Please help.

Solution:

On Android 8.0 (Oreo) you must have something called as a NotificationChannel So try the below implementation:

Step1: Create Notification Channel

private void createNotificationChannel() {

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        CharSequence name = getString(R.string.channel_name);
        String description = getString(R.string.channel_description);
        int importance = NotificationManager.IMPORTANCE_DEFAULT;
        NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);
        channel.setDescription(description);
        NotificationManager notificationManager = getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
    }
}

Finally: Then your Notification:

 NotificationCompat.Builder mBuilder =   new NotificationCompat.Builder(activity)
                .setSmallIcon(R.drawable.ic_launcher_background) // notification icon
                .setContentTitle("Notification!") // title for notification
                .setContentText("Hello word") // message for notification
                .setAutoCancel(true); // clear notification after click
Intent intent = new Intent(activity, RecorderActivity.class);
PendingIntent pi = PendingIntent.getActivity(activity,0,intent, PendingIntent.FLAG_UPDATE_CURRENT);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mBuilder.setContentIntent(pi);
notificationManager.notify(1, mBuilder.build());

Please compare this with Yours and see if it works

Try this, Hope it helps.
