I am getting ClassNotFoundException when trying to run the below code to start BroadCastReceiver. there is a custom notification and a buttonview to it, when i click the button the notification will close, but it is giving the below exception.
and i have created the notification channel for API 26 and above in OnCreate method too
public void OpenActivity(object sender, EventArgs e)
{
Intent intent = new Intent(this, typeof(DrawRect));
intent.SetFlags(ActivityFlags.ClearTop | ActivityFlags.SingleTop);
PendingIntent pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
RemoteViews remoteView = new RemoteViews(PackageName, Resource.Layout.NotificationLayout);
int notificationId = (int)SystemClock.CurrentThreadTimeMillis();
Intent buttonIntent = new Intent("button_clicked");
buttonIntent.PutExtra("id", notificationId);
PendingIntent buttonPendingIntent =
PendingIntent.GetBroadcast(this, notificationId, buttonIntent, 0);
remoteView.SetOnClickPendingIntent(Resource.Id.cloceNotification,
buttonPendingIntent);

Pending Intent or on click of Notification Does Not Open My desire Activity

please find the code of sendNotfication. I tried lots of things but still not working. Do I need to change in some Mainfest file ?
private void sendNotification(String messageBody) {
int requestID = (int) System.currentTimeMillis();
Intent intent = new Intent(getApplicationContext(), NotificationActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, requestID /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = getString(R.string.default_notification_channel_id);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setContentTitle(getString(R.string.fcm_message))
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(requestID/* ID of notification */, notificationBuilder.build());
}
Please find the mainfest file. This is the same that i found example in firbase. but still when i click on notfication it always went to SplashScreen.
I tried the recent comments but still not working.

You are using request Id in many places..
Please check the below working code to open the desired Activity :
Here , activity = CurrentActivity context,
mNotificationId = unique constatnt number like 200,201..e.t.c
Try the below code :
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(activity);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { mBuilder.setColor(activity.getResources().getColor(R.color.pricify_red));
mBuilder.setSmallIcon(R.drawable.transparent_img);
} else {
mBuilder.setColor(activity.getResources().getColor(R.color.pricify_red));
mBuilder.setSmallIcon(R.drawable.app_logo);
}
mBuilder.setContentTitle(title)
.setContentText(msg);
Intent i = new Intent();
i.setComponent(new ComponentName(currentActivity.this, DesiredActivity.class));
PendingIntent pIntent = PendingIntent.getActivity(activity, 0, i, 0);
mBuilder.setContentIntent(pIntent);
NotificationManager mNotificationManager =
(NotificationManager) activity.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(mNotificationId, mBuilder.build());

GCM Push Notifications not opening app

Whenever a gcm message comes back to my phone, I receive a notification. However, when I press it, it doesn't open my app. It only disappears. Previously when I used PendingIntent.FLAG_ONE_SHOT, it would work, but if I sent multiple messages, it wouldn't be up to date. Please help.
This is my notification code
public class GCMNotificationIntentService extends IntentService{
//set ID for the notification, so it can be updated
public static final int notifyID = 9001;
NotificationCompat.Builder builder;
public GCMNotificationIntentService() {
super("GcmIntentService");
}
#Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
Log.d("GCMN","GCMNTEST");
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType)) {
sendNotification("Deleted messages on server: "
+ extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
.equals(messageType)) {
sendNotification("Message Received from Google GCM Server:\n\n"
+ extras.get(AppConstants.MSG_KEY));
}
}
GCMBroadcastReceiver.completeWakefulIntent(intent);
}
private void sendNotification(String msg){
Intent resultIntent = new Intent(this, HomeActivity.class);
Log.d("RECEIVEDPT2",msg);
resultIntent.putExtra("msg", msg);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this,0,resultIntent,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mNotifyBuilder;
NotificationManager mNotificationManager;
mNotificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
mNotifyBuilder = new NotificationCompat.Builder(this).setContentTitle("Alert")
.setContentTitle("You've received a new message")
.setSmallIcon(R.drawable.ic_cast_dark);
//Set pending intent
mNotifyBuilder.setContentIntent(resultPendingIntent);
//Set vibration
int defaults = 0;
defaults = defaults | Notification.DEFAULT_LIGHTS;
defaults = defaults | Notification.DEFAULT_VIBRATE;
defaults = defaults | Notification.DEFAULT_SOUND;
mNotifyBuilder.setDefaults(defaults);
// Set the content for Notification
mNotifyBuilder.setContentText("You have new notifications");
// Set autocancel
mNotifyBuilder.setAutoCancel(true);
// Post a notification
mNotificationManager.notify(notifyID, mNotifyBuilder.build());
}

I can't seem to add FLAG_ACTIVITY_NEW_TASK as it doesn't compile.

Here is tested code that will help you to achieve the desired result.
private void notify(String msg) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Title")
.setVibrate(new long[]{5000})
.setLights(Color.GREEN, 3000, 3000) //for notification led light with color
.setContentText(msg)
.setAutoCancel(true)
.setSound(soundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}

Try to use:
`PendingIntent.getActivity(context, 0, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK);`
instead of
`PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);`
Please add android:exported="true" [http://developer.android.com/intl/es/guide/topics/manifest/service-element.html] in android manifest inside activity tag which is supposed to be opened after tapping notification from status bar.

Unable to receive push notifications (android)

I have written very simple code (just for demo) for push notification following google developers guide. I am sending notification using Postman but I can't receive it on my emulator. I am using blue stacks with google play services. Here is my code
public class MainActivity extends AppCompatActivity {
#Override

super.onCreate(savedInstanceState);

try {
token = instanceID.getToken("590106578883",

} catch (IOException e) {
Log.d("TAG", e.getMessage());
}
Log.d("TAG", token + "");
int i = 0;
}
}).start();
} // onCreate
} // MainActivity
