I'm having an intermittent problem in which opening my Nativescript based app from a notification does not always take me to the last view the app was on when I minimized it. I'm currently experiencing this on Android 5.1.1.
I know that the Resume event is called when ever the app re-opens and I can put some logic in there to force a certain view to load but oddly it's not always a common problem. When opening the app from a notification, the resume event is hit, and then it just defaults to the start screen of my app. This is not what I want. Is this expected behavior? It doesn't seem like it is since it's intermittent but seems to be happening more often now.
Note: I'm using the Nativescript push plugin to handle client side notifications. I'm also still using NS 2.2.1 since there seemed to be some issues in 2.3 and #next

all day I already despair of a waking up system for my VoIP app. I must have already read over 100 articles and documentation about it, however I have not found a solution that works for me.
Use case:
My app is running in the background. That means the home button was pressed
after my app was started and the device is in the home screen. As soon as a notification arrives, the app is supposed to open again on a certain route because a call is coming in.
In the lock screen I managed this pretty easily with flutter_local_notifications and within the app it was of course no problem either.
Note:
Only Android is important, the rest can be neglected
Android version 10+
Flutter version 2+
I appreciate any input on how to solve my problem and have a good week.
Kind regards,

I have a App that i now wanted to expand with Silent Push Functionality for a customers Feature Request.
But now i encounter a rather strange behaviour(app freeze)
The Used Xamarin.Forms Version is 4.8.0.1451 (Updates did not solve the problem)
The Problem is Android Only related
Normal Notifications work as expected and dont produce any error
Here the quick Behaviour:
Receiving Silent Pushes works if the app is in Foreground (Multible times no limit)
Bringing the App to the Background and back to Foreground works also flawles
Do i Receive a Silent Push while the App is in Background or the Device is Locked and i bring back the App to Foreground/Unlock the device the app seems frozen (unresponsive and App.OnResume does not get executed)
(Also to note: i can only receive 1 silent push when the app is in Background/Device is locked)
For now i dont do anything on receiving the Silen push (to isolate this error)
Debug output aswell as LogCat does not provide any info what so ever.
i could not track any managed code that does execute and not return properly from some method calls
i can reproduce this problem on android 11(Pixel3) and android 9(Blackview A60)
I hope someone here has an idea what this problem could be.
It more informations or details are needed, i happily provide
In Android, starting in Android 8.0 (API level 26), an Android application no longer have the ability to run freely in the background.
When in the foreground, an app can start and run services without
restriction. When an application moves into the background, Android
will grant the app a certain amount of time to start and use services.
Once that time has elapsed, the app can no longer start any services
and any services that were started will be terminated. At this point
it is not possible for the app to perform any work.
For more details about this, you can refer to Background Execution Limits in Android 8.0.
I've been asked to fix an android application which has issues after switching to a newer device. The switch was from android 7/8 to 11. The application opens up google maps for navigation but very often when returned to the app all data is lost, and clicking on anything will reset it back to the startup activity. It doesn't matter which apps it switches between the issue happens with all of them.
I've tried several things:
-Disabling all battery saving options on the device
-Using OnSaveInstanceState to retain the data
-Using a backgroundservice to retain the data
The issue only occurs on actual devices, using an emulator results in no errors.
When the debugger is attached to the application it loses its connection before returning to the app. It is possible to re-attach when returning to the app but it disconnects as soon as
anything is clicked.
And best of all there's literally no error message shown anywhere.
The following comment provided the solution I needed.
You would need to start a foreground service, complete with its Notification. Even that does not guarantee that your process will remain around.

Problem:
I am working with custom UI, now. There are some threads inside a program. Sometimes system shows message that my app has stopped. But it's false in my case. My app instantly restores itself and keeps working so everything is just fine.
Question:
Is there a way to disable any system messages appearing?
I am new in android and will be really grateful for some advice.
(edit)
Well so i found the following. App crushes on start after it was "closed" by hardware "<-- Back" button. Not every time only sometimes. When i select it in menu of opened apps once more it opens normally and runs just fine. Is there a way to remove that "crush" message? sure i do understand that app has crushed and its not good at all.
I am working on an app with PhoneGap on android where the user will get messages every now and then bringing them to one of the pages on the app. I've looked at a few possibilities but haven't found any simple way to do this. Can I use the built in Notification on the Phonegap API to do this?
I have found a few good ways to do push notifications like thisw: http://www.pushwoosh.com/programming-push-notification/android-push-notification-for-phonegap/ but I want the notification to be coming from the app itself with the time determined by a built in timer.
Thanks!
You can't, not in Phonegap anyway. If the user leaves the app with the Home button, then the code is still running (until it gets killed when memory gets low). But if the user exists with the back key, the app dies. See here: Creating an Android Service with Phonegap? (Have phonegap app run even when closed)
