Android Question How to Run "MQTT Android App" in Background

[Adamdam]

Dear All:

I need to make my Android App work in background (i.e. mobile screen off, or I work with other program).
example: whatsapp give alert at any time when receiving new message.

in other word:
I need the app on this link :
- https://www.b4x.com/android/forum/t...-the-home-temperature-with-adafruit-io.80820/
or what in this link:
- https://www.b4x.com/android/forum/threads/b4x-mqtt-chat-room.61568/


give alert (notification message, ring,...) indicating the new temperature (say other threshold level) received.

Thanks in advance for all.

Whatsapp is NOT using MQTT, it uses Firebasemessaging.
Maybe both..

Where did you get this info?

Out of curiosity i decompiled whatsapp time ago.

Did it again just now to answer your question.

this is part of the Manifest from Whatsapp.

<receiver android:name="com.google.android.gms.measurement.AppMeasurementReceiver" android:enabled="true" android:exported="false"/>
<receiver android:name="com.google.android.gms.measurement.AppMeasurementInstallReferrerReceiver" androidermission="android.permission.INSTALL_PACKAGES" android:enabled="true" android:exported="true">
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER"/>
</intent-filter>
</receiver>
<service android:name="com.google.android.gms.measurement.AppMeasurementService" android:enabled="true" android:exported="false"/>
<service android:name="com.google.android.gms.measurement.AppMeasurementJobService" androidermission="android.permission.BIND_JOB_SERVICE" android:enabled="true" android:exported="false"/>
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" androidermission="com.google.android.c2dm.permission.SEND" android:exported="true">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE"/>
<category android:name="com.whatsapp"/>
</intent-filter>
</receiver>
<service android:name="com.google.firebase.iid.FirebaseInstanceIdService" android:exported="true">
<intent-filter androidriority="-500">
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
<provider android:name="com.google.firebase.provider.FirebaseInitProvider" android:exported="false" android:authorities="com.whatsapp.firebaseinitprovider" android:initOrder="100"/>

This leads me to the info it is using Firebasemessaging
