I am working with xamarin forms. In Xamarin Android I received the notification when app not in foregroud/backgroud (i.e killed the app). When clicking on the notification I need to navigate to specific page.
protected override void OnNewIntent(Intent intent)
{
base.OnNewIntent(intent);
string notificationMessage = intent.GetStringExtra(Constants.MESSAGE);
string notificationThreadId = intent.GetStringExtra(Constants.MESSAGE_THREAD_ID);
bool isFromNotificaion = true;
PushNotificationLog notificationLog = new PushNotificationLog(notificationMessage, notificationThreadId, isFromNotificaion);
ConferenceMobileApp.App app = new App(notificationLog);
LoadApplication(app);
}
The OnNewIntent is called when app in foreground or background , not when app is killed.
And my notification send code is below
void SendNotification(RemoteMessage message)
{
string messageBody = "";
string messageThreadId = "";
message.Data.TryGetValue(MESSAGE,out messageBody);
message.Data.TryGetValue(MESSAGE_THREAD_ID, out messageThreadId);
string messageLogId = "0";//message.Data.TryGetValue(MESSAGE_LOG_ID);
var intent = new Intent(this, typeof(MainActivity));
intent.AddFlags(ActivityFlags.ClearTop);
intent.AddFlags(ActivityFlags.SingleTop);
intent.PutExtra(MESSAGE, messageBody);
intent.PutExtra(MESSAGE_THREAD_ID, messageThreadId);
//intent.PutExtra(MESSAGE_LOG_ID, messageLogId);
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
var notificationBuilder = new Notification.Builder(this).SetSmallIcon(Resource.Drawable.common_google_signin_btn_icon_dark)
.SetContentTitle("PKConf")
.SetContentText(messageBody)
.SetAutoCancel(true)
.SetContentIntent(pendingIntent);
var notificationManager = NotificationManager.FromContext(this);
//setting notification id
int notificaionId = Convert.ToInt32(messageLogId);
notificationManager.Notify(notificaionId, notificationBuilder.Build());
}
How could I achieve this when app is not in foreground/background?
Please try with below events in your mainactivity.cs
protected override void OnResume()
{
base.OnResume(); // Always call the superclass first.
}
protected override void OnPause()
{
base.OnPause(); // Always call the superclass first
}
You can try overriding OnResume
protected async override void OnResume()
{
base.OnResume();
// Your Code. I would guess same code as you have in OnNewIntent
}

so I have an application that is as follows:
login page where the user enters his credentials and can access the main app if his credentials are correct. and if he checks the remember me checkbox, his username and password will be saved in shared preferences so that he can directly go to the main app in the second time.
the main app has a tabbed layout with a viewpager. in one of the tabs, which is a fragment, I use a recyclerview to display data, that I get from a database, in rows.
now in each row there is a reply button that will show details corresponding to each row when clicked. the details will be shown in a new fragment.
so the point is that I managed to replace the tab's fragment with the new fragment using this code in the recyclerview's adapter:
public class recyclerviewAdapter : RecyclerView.Adapter
{
// Event handler for item clicks:
public event EventHandler<int> ItemClick;
List <summary_request> summary_Requests=new List<summary_request>();
//Context context;
public readonly stores_fragment context;
public recyclerviewAdapter(stores_fragment context, List<summary_request> sum_req)
{
this.context = context;
summary_Requests = sum_req;
}
public override RecyclerView.ViewHolder
OnCreateViewHolder(ViewGroup parent, int viewType)
{
View itemView = LayoutInflater.From(parent.Context).
Inflate(Resource.Layout.recycler_view_data, parent, false);
recyclerview_viewholder vh = new recyclerview_viewholder(itemView, OnClick);
return vh;
}
public override void
OnBindViewHolder(RecyclerView.ViewHolder holder, int position)
{
recyclerview_viewholder vh = holder as recyclerview_viewholder;
vh.by_user.Text = summary_Requests[position].By;
vh.warehousename.Text = summary_Requests[position].warehousename;
vh.project.Text = summary_Requests[position].project;
vh.operations_note.Text = summary_Requests[position].destination_Note;
vh.source_Note.Text = summary_Requests[position].source_Note;
vh.stockType.Text = summary_Requests[position].stockType;
vh.requestStatus.Text = summary_Requests[position].requestStatus;
vh.reply.Click += delegate
{
summary_detail_req fragment = new summary_detail_req();
var fm = context.FragmentManager.BeginTransaction();
fm.Replace(Resource.Id.frameLayout1, fragment);
fm.AddToBackStack(null);
fm.Commit();
int nb = context.FragmentManager.BackStackEntryCount;
Toast.MakeText(context.Context, nb.ToString(), ToastLength.Long).Show();
};
}
private void Reply_Click(object sender, EventArgs e)
{
Toast.MakeText(context.Context, "reply" , ToastLength.Long).Show();
}
public override int ItemCount
{
get { return summary_Requests.Count; }
}
// Raise an event when the item-click takes place:
void OnClick(int position)
{
if (ItemClick != null)
ItemClick(this, position);
}
}
but my context.FragmentManager.BackStackEntryCount remain zero! I don't get it. in my main activity, I am using this code for the backpress function:
stores_fragment.recyclerviewAdapter adapter;
public override void OnBackPressed()
{
string userName = pref.GetString("Username", String.Empty);
string password = pref.GetString("Password", String.Empty);
if (userName != String.Empty || password != String.Empty && adapter.context.FragmentManager.BackStackEntryCount == 0)
{
this.FinishAffinity();
}
else
base.OnBackPressed();
}
but i'm not getting what i want. this function is getting me out of the whole app.the first part of the if statement is because without it, when the I press the back button from the main activity it takes me back to the login page and I don't want that.
my question is what should I do to manage my fragments and the backpress function?
thanks in advance.
so the point is that I managed to replace the tab's fragment with the new fragment using this code in the recyclerview's adapter
According to your description, you want to open another fragment from recyclerview Button.click, if yes, please take a look the following code:
on OnBindViewHolder
int selectedindex;
// Fill in the contents of the photo card (invoked by the layout manager):
public override void
OnBindViewHolder(RecyclerView.ViewHolder holder, int position)
{
selectedindex =position;
PhotoViewHolder vh = holder as PhotoViewHolder;
// Set the ImageView and TextView in this ViewHolder's CardView
// from this position in the photo album:
vh.Image.SetImageResource(mPhotoAlbum[position].PhotoID);
vh.Caption.Text = mPhotoAlbum[position].Caption;
vh.btnreply.Click += Btnreply_Click;
}
To show detailed activity. MainActivity is the current activity for recyclerview.
private void Btnreply_Click(object sender, EventArgs e)
{
Showdetailed(selectedindex);
}
private void Showdetailed(int position)
{
var intent = new Intent();
intent.SetClass(MainActivity.mac, typeof(DetailsActivity));
intent.PutExtra("selectedid", position);
MainActivity.mac.StartActivity(intent);
}
The detailedactivity.cs:
public class DetailsActivity : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
var index = Intent.Extras.GetInt("selectedid", 0);
var details = DetailsFragment.NewInstance(index); // Details
var fragmentTransaction = FragmentManager.BeginTransaction();
fragmentTransaction.Add(Android.Resource.Id.Content, details);
fragmentTransaction.Commit();
}
}
The DetailsFragment.cs:
public class DetailsFragment : Fragment
{
public int ShownPlayId => Arguments.GetInt("selectedid", 0);
public static DetailsFragment NewInstance(int index)
{
var detailsFrag = new DetailsFragment { Arguments = new Bundle() };
detailsFrag.Arguments.PutInt("selectedid", index);
return detailsFrag;
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
// Use this to return your custom view for this Fragment
// return inflater.Inflate(Resource.Layout.YourFragment, container, false);
if (container == null)
{
// Currently in a layout without a container, so no reason to create our view.
return null;
}
var scroller = new ScrollView(Activity);
var text = new TextView(Activity);
var padding = Convert.ToInt32(TypedValue.ApplyDimension(ComplexUnitType.Dip, 4, Activity.Resources.DisplayMetrics));
text.SetPadding(padding, padding, padding, padding);
text.TextSize = 24;
Photo photo =PhotoAlbum.mBuiltInPhotos[ShownPlayId];
text.Text = photo.Caption;
scroller.AddView(text);
return scroller;
}
}

Hi StackOverflow Team,
I am trying to run a background process in my App. This background process should update just Background image on one of the pages in the App every 15 seconds. So far, I tried to create a timer in the App OnStart() method and update the backgroundimage of the page in the BeginInvokeOnMainThread() method but with no success. Can anyone help me with this?
My Code -
{
private static Stopwatch stopWatch = new Stopwatch();
private const int defaultTimespan = 20;
private readonly HomePage homePage;
public App()
{
InitializeComponent();
try
{
MainPage = new MainPage();
homePage = new HomePage();
}
catch(Exception ex)
{
string str = ex.Message;
}
}
protected override void OnStart()
{
if (!stopWatch.IsRunning)
{
stopWatch.Start();
}
Device.StartTimer(new TimeSpan(0, 0, 10), () =>
{
// Logic for logging out if the device is inactive for a period of time.
if (stopWatch.IsRunning && stopWatch.Elapsed.Seconds >= defaultTimespan)
{
//prepare to perform your data pull here as we have hit the 1 minute mark
// Perform your long running operations here.
Device.BeginInvokeOnMainThread(() =>
{
// If you need to do anything with your UI, you need to wrap it in this.
// homePage.BackgroundImageSource = "goldengate.jpg";
homePage.ChangeBackgroundImage();
});
stopWatch.Restart();
}
// Always return true as to keep our device timer running.
return true;
});
}
protected override void OnSleep()
{
//stopWatch.Reset();
}
protected override void OnResume()
{
//stopWatch.Start();
}
//void ChangeHomePageImage()
//{
// Navigation.PushAsync(new HomePage(appBackground));
// Navigation.RemovePage(this);
//}
}
MainPage -

this.firstStacklayout.Margin = new Thickness(0, (Application.Current.MainPage.Height * 0.25), 0, 0);
base.OnAppearing();
}
you are creating an instance of HomePage and trying to update it, but it is NOT the same instance that is being displayed in your MasterDetail
try something like this
var md = (MasterDetailPage)MainPage;
var nav = (NavigationPage)md.DetailPage;
var home = (HomePage)nav.CurrentPage;
home.ChangeBackgroundImage();
alternately, you could use MessagingCenter to send a message to HomePage requesting that it udpate
I am working on xamarin.forms app and I am setting local notification using alarm manager. It is triggering fine on android version 8 and 9 but somehow it's not triggering in Android 10.
In android device logs for Android 10, I got
07-22 15:00:06.612 Samsung SM-M205F Verbose 4185 SamsungAlarmManager Sending to uid : 10244 action=null alarm=Alarm{a757a70 type 0 when 1595410200000 com.MyApp.andr.connect}
07-22 15:00:06.613 Samsung SM-M205F Warning 4185 BroadcastQueue Unable to launch app com.MyApp.andr.connect/10244 for broadcast Intent { flg=0x14 cmp=com.MyApp.andr.connect/crc640e87e93c5dbd1629.AlarmReceiver (has extras) }: process is bad
Update (Issue is still with Android 10)
I have managed to get notification when app is running, but now notifications are not firing when app is closed.
Note : I have made a sample which is working just fine with Android 10, Notifications are triggering when app is running or closed in the sample. I don't have to use foreground service. (I have used same approach in my work project). So There is something wrong in my work project which I am not able to figure out.
Here is the Android device logs when app is closed and notifications are about to trigger,
If someone can help !
All of the code will be frozen when your application is closed including the alarm manager.
If you want it still alive, we could use foreground service:
https://learn.microsoft.com/en-us/xamarin/android/app-fundamentals/services/foreground-services
This may be a little out of date, here is my approach to create the notification:
[Service]
public class SampleService : Service
{
public static string CHANNEL_ID = "com.channelid";
public static string CHANNEL_NAME = "com.channelname";
public override void OnCreate()
{
base.OnCreate();
}
public override StartCommandResult OnStartCommand(Intent intent, [GeneratedEnum] StartCommandFlags flags, int startId)
{
registerNotificationChannel();
int notifyId = (int)JavaSystem.CurrentTimeMillis();
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID);
mBuilder.SetSmallIcon(Resource.Mipmap.ic_launcher);
if (Build.VERSION.SdkInt < BuildVersionCodes.N)
{
mBuilder.SetContentTitle("app name");
}
StartForeground(notifyId, mBuilder.Build());
return StartCommandResult.Sticky;
}
private void registerNotificationChannel()
{
if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
{
NotificationManager mNotificationManager = (NotificationManager)GetSystemService(Context.NotificationService);
NotificationChannel notificationChannel = mNotificationManager.GetNotificationChannel(CHANNEL_ID);
if (notificationChannel == null)
{
NotificationChannel channel = new NotificationChannel(CHANNEL_ID,
CHANNEL_NAME, NotificationImportance.High);
channel.EnableLights(true);
channel.LightColor = Color.Red;
channel.LockscreenVisibility = NotificationVisibility.Public;
mNotificationManager.CreateNotificationChannel(channel);
}
}
}
public override IBinder OnBind(Intent intent)
{
throw new NotImplementedException();

In my Xamarin Forms app, I am using native Android code for the platform. I want to show a AlertDialog.Builder and catch the event when the user taps outside of the dialog box with SetOnCancelListener. This is my code:
AlertDialog.Builder adb = new AlertDialog.Builder(this);
adb.SetTitle("title");
adb.SetItems(myItems.Select(x => x.Name).ToArray(), (s, e) =>
{
// not important code
});
var cancelled = new CancelListener();
cancelled.Cancelled += (s, e) =>
{
// not important code
};
adb.SetCancelable(true);
adb.SetOnCancelListener(cancelled);
Dialog d = adb.Create();
d.Show();
My CancelListener class:
public class CancelListener : Java.Lang.Object, IDialogInterfaceOnCancelListener
{
public event EventHandler Cancelled;
public IntPtr Handle => IntPtr.Zero;
public CancelListener() : base()
{
}
public void Dispose()
{
Cancelled = null;
}
public void OnCancel(IDialogInterface dialog)
{
Cancelled?.Invoke(null, EventArgs.Empty);
}
}
When I tap outside of the dialog box I get the message:
System.NotSupportedException: Unable to activate instance of type
MyProject.CancelListener from native handle
I just want to know about the banner advertisements supported with Xamarin.Forms without any patch or loophole. Is there any advertisement provider who are providing their SDKs with the Xamarin.Forms?
Thanks in advance.
There are both SDK and step-by-step examples for Google AdMob for Xamarin.Android. You are going to need the Xamarin.GooglePlaySerives.Ads nuget.
I use it to show ads in my Xamarin.Forms app published at Google Play.
Here is the sample code for the android part of your application:
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using Android.Support.V7.App;
using Android.Gms.Ads;
using Android;
namespace AdMobExample
{
[Activity (Label = "#string/app_name", MainLauncher = true)]
public class MainActivity : AppCompatActivity
{
protected AdView mAdView;
protected InterstitialAd mInterstitialAd;
protected Button mLoadInterstitialButton;
protected override void OnCreate (Bundle savedInstanceState)
{
base.OnCreate (savedInstanceState);
SetContentView (Resource.Layout.activity_main);
mAdView = FindViewById<AdView> (Resource.Id.adView);
var adRequest = new AdRequest.Builder ().Build ();
mAdView.LoadAd (adRequest);
mInterstitialAd = new InterstitialAd (this);
mInterstitialAd.AdUnitId = GetString (Resource.String.test_interstitial_ad_unit_id);
mInterstitialAd.AdListener = new AdListener (this);
mLoadInterstitialButton = FindViewById<Button> (Resource.Id.load_interstitial_button);
mLoadInterstitialButton.SetOnClickListener (new OnClickListener (this));
}
protected void RequestNewInterstitial ()
{
var adRequest = new AdRequest.Builder ().Build ();
mInterstitialAd.LoadAd (adRequest);
}
protected void BeginSecondActivity ()
{
var intent = new Intent (this, typeof(SecondActivity));
StartActivity (intent);
}
protected override void OnPause ()
{
if (mAdView != null) {
mAdView.Pause ();
}
base.OnPause ();
}
protected override void OnResume ()
{
base.OnResume ();
if (mAdView != null) {
mAdView.Resume ();
}
if (!mInterstitialAd.IsLoaded) {
RequestNewInterstitial ();
}
}
protected override void OnDestroy ()
{
if (mAdView != null) {
mAdView.Destroy ();
}
base.OnDestroy ();
}
class AdListener : Android.Gms.Ads.AdListener
{
MainActivity that;
public AdListener (MainActivity t)
{
that = t;
}
public override void OnAdClosed ()
{
that.RequestNewInterstitial ();
that.BeginSecondActivity ();
}
}
class OnClickListener : Java.Lang.Object, View.IOnClickListener
{
MainActivity that;
public OnClickListener (MainActivity t)
{
that = t;
}
public void OnClick (View v)
{
if (that.mInterstitialAd.IsLoaded) {
that.mInterstitialAd.Show ();
} else {
that.BeginSecondActivity ();
}
}
}
}
}
There is also a ste-by-step guide for AdMob ads for Xamarin.iOS:
using Google.MobileAds;
...
const string intersitialId = "<Get your ID at google.com/ads/admob>";
Interstitial adInterstitial;
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
CreateAndRequestInterstitial ();
}
public void AfterSomeTime ()
{
if (adInterstitial.IsReady)
adInterstitial.PresentFromRootViewController (navController);
}
void CreateAndRequestInterstitial ()
{
adInterstitial = new Interstitial (intersitialId);
adInterstitial.ScreenDismissed += (sender, e) => {
// Interstitial is a one time use object. That means once an interstitial is shown, HasBeenUsed
// returns true and the interstitial can't be used to load another ad.
// To request another interstitial, you'll need to create a new Interstitial object.
adInterstitial.Dispose ();
adInterstitial = null;
CreateAndRequestInterstitial ();
};
var request = Request.GetDefaultRequest ();
// Requests test ads on devices you specify. Your test device ID is printed to the console when
// an ad request is made. GADBannerView automatically returns test ads when running on a
// simulator. After you get your device ID, add it here
request.TestDevices = new [] { Request.SimulatorId.ToString () };
adInterstitial.LoadRequest (request);
}
