NotificationCompat.Builder: Cannot resolve assembly method ()
I have the following simple class that I would like to use to notify the user of incoming messages (I will develop this as I add the application). But at the moment, the last line has the following error and I cannot run it:
Cannot resolve build () method
Here is the code:
import android.app.Activity;
import android.app.NotificationManager;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
public class UserNotificationActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void triggerNoti() {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My notification")
.setContentText("Hello World!");
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(001, mBuilder.build());
}
}
I tried this solution but didn't change anything
What am I doing wrong?!
PS : Target (& min) sdk = 21

The notification method is slightly changed in support for V4 and above API level 19, you can try the lower code block.
public void sendNotification(String message, String title, Intent intent, int not_id) {
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notification;
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
notification
= new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.app_icon)
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setContentTitle(title)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
} else {
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.app_icon);
notification
= new NotificationCompat.Builder(this)
.setContentTitle(title)
.setSmallIcon(R.drawable.small_icon)
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setContentText(message)
.setAutoCancel(true)
//.setColor(Color.parseColor("#1a4994"))
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setLargeIcon(bitmap)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
}
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(not_id, notification.build());
}
Update for NotificationChannel :
public void initChannels(Context context) {
if (Build.VERSION.SDK_INT < 26) {
return;
}
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel channel = new NotificationChannel("default",
"Channel name",
NotificationManager.IMPORTANCE_DEFAULT);
channel.setDescription("Channel description");
notificationManager.createNotificationChannel(channel);
}
