我正在使用此代码在我的android应用程序中显示通知。这在所有android版本中都可以正常工作,但是在Android 9中没有任何通知显示。
我试图用不同的方法来实现这一点,但没有任何效果。
public void showNotification(String heading, String description, String imageUrl, Intent intent){
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
createChannel();
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this,"channelID")
.setSmallIcon(R.drawable.logo)
.setContentTitle(heading)
.setContentText(description)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
int notificationId = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
notificationManager.notify(notificationId, notificationBuilder.build());
}
public void createChannel(){
if (Build.VERSION.SDK_INT < 26) {
return;
}
NotificationManager notificationManager =
(NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel channel = new NotificationChannel("channelID","name", NotificationManager.IMPORTANCE_DEFAULT); …Run Code Online (Sandbox Code Playgroud)
