Unfortunately that did not work. I am now trying to continue my project using qtcloudmessaging
In the instructions it says under point 5:
"First install QtCloudMessaging from the command line:
qmake "CONFIG + = Embedded-Kaltiot Firebase" make make install "

I do not know how do I install it from the command line. ... I use windows 10

[Robin Hood]

So I think I found where it is to install QtCloudMessaging. You can see it in the first picture. I hope that was right.
But the compiler is still nagging :/

I have copy the compiler report:

C:\Users\Robin\QtProjects\build-qtcloudmessaging-Android_f_r_armeabi_v7a_GCC_4_9_Qt_5_11_1_for_Android_armv7-Debug\lib\libQt5CloudMessaging.so konnte nicht gefunden werden

If you want to help me, I think it would be easiest if you look at the manual -> qtcloudmessaging
:)

Here are three more pictures. Maybe they will help you with troubleshooting:

[jsulm]

@Robin-Hood Did you add include/lib locations for qtcloudmessaging in your pro file?

[Robin Hood]

@jsulm

I do not know. Where would I have to add that and how would that look exactly?

[jsulm]

@Robin-Hood Take a look at "Linking your application against the shared library" chapter in https://wiki.qt.io/How_to_create_a_library_with_Qt_and_use_it_in_an_application

[Robin Hood]

@jsulm
I do not see any libs I could add. I have done it as it says in the instructions under point 6.
Here is the link to the instructions: QtCloudMessaging
So I wrote the code to several pro files:
QT + = cloud messaging
QT + = cloudmessagingfirebase

Before that, I added the code in my qmake scribt:
"CONFIG + = firebase",
as I the instructions under point 1 stands.
If you scroll something up, you can see it in the first picture.

@Robin-Hood said in Push Notifications in QT:

QT + = cloud messaging

it should be

QT + = cloudmessaging

Shouldn't you do the include like this

#include <QtCloudMessaging>

?

[Robin Hood]

@jsulm

Yes, I was just prescribed. That's what I wrote in the code. I just downloaded the package from Githup and followed the instructions ...

Hello,

I would like to integrate the existing Qt project QtFirebase Example in another Qt project. I thought about a solution via libs (libaries). When it exists a simple method, for example with libs or other, I'm grateful for comments. Otherwise I know that you can subdivide via subdir, but I would need a step by step statement.

To clarify again, my point is to include push notifications in an existing Qt project. I've done the QtFirebase Example and I can get push notifications. Now I would like to integrate this functionality into another project. As mentioned earlier, it would be best if I clicked "Add to Library" within another project and the push notification feature is added.

Surely there must be a possibility, I am convinced of that. Request for feedback.
