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.
As far as I know you can add notification channel only for versions greater than or equal 26, the versions below android 8.0 doesn't support notification channel. My suggestion would be using following codes:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, ADMIN_CHANNEL_ID)
}
else NotificationCompat.Builder(context)
First create notification channel and notification passing channel ID.
NotificationManager notificationManager = (NotificationManager)context
.getSystemService(Context.NOTIFICATION_SERVICE);
buildNotificationChannel(manager,String <Channel_ID>,String description);
Create Notification channel.
public void buildNotificationChannel(NotificationManager manager, String channelID,
String description) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
if (manager.getNotificationChannel(channelID) == null) {
NotificationChannel channel = new NotificationChannel(channelID,
description,NotificationManager.IMPORTANCE_LOW);
channel.setDescription(description);
manager.createNotificationChannel(channel);
}
}
}
Create Notification passing argument channel ID
Notification notification = new
NotificationCompat.Builder(context,<Channel_ID>)
.setSmallIcon(R.drawable.app_icon)
.setContentTitle("Title goes here.")
.setPriority(Notification.PRIORITY_HIGH)
.setContentIntent(pendingIntent)
.setAutoCancel(false)
.setOngoing(true)
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setContentText("Content Text").build();
notificationManager.notify(ID,notification);
