Push FCM Xamarin like WhatsApp background

I have a problem on Devices Xiaomi and Lenovo Phones, when i close app from task manager they stop receive GCM messages, the gcm messages receive only at foreground and app on task manager list. How do i to keep app or service running on close at task manager? Obs: samsung phones keep as well on both cases.
As stated in this thread, Lenovo mobiles are using Background task killer to stop background apps. To hide task killer, untick restrict in application menu.
Also, as mentioned by #AL. in this post, it may very well be possible that when an app is stopped from multi-task tray in that device, it is actually killing the app, causing the services and other background processes associated with it to also be destroyed. Suggested action is to make use of the START_STICKY flag.
Another reference which might help.
In Xiaomi phones, they whitelist or blacklist an app based on certain criteria. If you download an app and if it is in their whitelist, they'll permit the app to show notifications. If not, you already know what happens. But the good thing is that you can change these settings. Look for an app named Security. If you revoke the right permissions, even WhatsApp will stop showing notifications.

Xamarin.Forms Launch or Wake app on bluetoothle button push

I now have a requirement for an iOS/Android app (Xamarin.Forms) to either wake or launch when a paired BluetoothLE button is pressed. The app may be in the background or even closed.
I have a POC app (modeled after Acr.Ble samples) and I'm currently using CoreBluetooth to scan and connect to the device and get services etc... I'm not sure what I need to do to get the app to wake or launch when the button is pressed.
I know Android and iOS may handle these things differently, so a cross-platform solution is not a requirement.
Any help is greatly appreciated!

Is it possible to create custom Android Wear notifications?

I have been doing lots of research trying to figure out if it is possible to create wear notifications with custom layouts over the past few months, but am struggling to find a solution.
I have tried to implement the following suggestions to no luck:

Custom UI for Android Wear Notifications
Most of what I have read have instructed that in order to do this, I should create an android wear app with a data listener. The idea being the phone would send certain data to the watch (say a string) based on the type of notification it wants to send. I would disable the automatically generated wear notification. In its place, the Android Wear app listener would know what type of notification it is based on the string and display my custom pages for that notification instead.
My first problem I have run into is I have no idea how to debug code like this. Since in Android studio you can only launch the device app or the wear app, but not both at the same time.
The other question I have is, does the Android Wear app run in the background when the Device App is running? Do you have to open the Android Wear App first for the listener to be even working (if so then I guess this is not a solution to custom notifications)?
Is it actually possible to create custom layout android wear notifications?
If you want to use a custom layout for your notifications, you should create the notification on the watch, following Creating Custom Layouts. You can even make the custom notifications clickable, you can add actions that will open activities on the watch, etc.
For that, you can send a message from your phone to your watch and the listener implemented on your watch will receive it and then, create and display the notification using the correct layout corresponding to the message sent, for example.
In this case, the best way is to implement a WearableListenerService on your wearable. Its lifecycle is handled by the system which binds it only when necessary.
To debug, you install the wear app on the wear emulator or your watch, you install the mobile app on your phone and finally you connect the two following this tutorial if you're using the emulator or via bluetooth if you're using a watch (link in the tutorial).
The Android Wear app connects your phone to your watch, whether it is an emulator or not. So, in order for your message to be received, you must have connected wear and mobile via Android Wear. Then, once the connection is established, you don't necessarily need to keep it open. So yes, the Android Wear app runs in background.

Win 10 app not running on minimizing

I have made a IoT beacon reading app. I am using DispatchTimer to get signal for 10 sec then processing it to retrieve some result. Everything is working fine if app is not minimized. but when app is minimized or I work on some other thing then App is not working at all. I have handle App suspended event but still on minimizing the app I am not able show the result.
To keep your app running when minimized, you need to create an ExtendedExecutionSession in your app. Read more details here:

Implementing error logging in windows phone 7 app? [duplicate]

I don't have a WP7 device yet. Everything is functional in My App on a Simulator, but when my customer test it, app does not function at all. e.g. VDO is not playing.
Is there a way to get a crash log from Windows Phone 7? (like iPhone).
You can easily create your own crash report. Basically this is what you have to do:
In your App class add an handler for the UnhandledException event
inside the handler prepare a log with everything you need (stacktrace, memory allocated, etc.)
use an email composer Task to send the report.
You can also check BugSense which is a cross-platform(iPhone,Android and Windows Phone) tool that collects and analyzes crash reports from mobile apps.
Disclaimer: I have developed the WP7 plugin.
