Android Question admob Firebase problem

kisoft · Feb 6, 2018

I followed this tutorial
https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/
https://www.b4x.com/android/forum/t...tegrated-with-firebase-backend.67710/#content

The following error occurs:

B4A Version: 7.80
Parsing the code. (0.25s)
Compiling the code. error
The object reference has not been set to the instance of the object.

May I ask way?

abhishek007p · Feb 6, 2018

in the manifest editor comment this line and see if it compiles, if yes then json file is either missing or invalid.

'CreateResourceFromFile("google-services", "google-services.json")

kisoft · Feb 6, 2018

I copied everything to the manifest only from this post
https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/
there is no this line of code.
Do I still have something to paste into the manifesto?

abhishek007p · Feb 6, 2018

you need to add the following manifest - Google Play Services Base, Firebase Base, Firebase Ads

kisoft · Feb 6, 2018

yes, I have these components pasted.
after commenting on this line of code, I am getting this error

i suggest your to make a sample project only for ads and then test out the ads to isolate and detect the problem.
you also need to install the following components from SDK manager - Android Support Repository, Google Play services, Google Repository.

Found answer to your problem. download the latest android image or at least the one you are targeting. https://www.b4x.com/android/forum/threads/runtimepermissions-library-issue.89210/

OK
Thank you for your help.
I will try this

kisoft · Feb 6, 2018

setting to : "C:\android-sdk\platforms\android-27\android.jar" it helped, now the program compiles.
When I uncomment the line : "CreateResourceFromFile("google-services", "google-services.json"
the problem remains

B4A Version: 7.80
Parsing the code. (0.25s)
Compiling the code. error
The object reference has not been set to the instance of the object.
Whether it can be a problem with the file google-services.json?

Erel · Feb 7, 2018

There is a bug in v7.80 which causes it to show this error message instead of the real error when there is an error in the manifest editor.

Can you post the full manifest code?

I thought that you wrote that you still get this error after you comment the CreateResourceFromFile line.

Have you copied the json file to the project folder?

Does the package name in the json file match your project package name?

kisoft · Feb 7, 2018

I will listen to abhishek007p and create a new project with a new file.
Thank you for your answer.

abhishek007p · Feb 7, 2018

you dont need Firebase Notifications, Firebase Auth if you just want to show ads.

you need to get the json file from admob website (it is unique for each project). if you dont have this file then you have to comment the line CreateResourceFromFile and test ads will still work. i assume you are just starting out, so i suggest you to test your project from the test ad ids.

kisoft · Feb 8, 2018

Ok.
Do I have to place applications in the google store?

I will answer myself:
you do not need to install applications in the google store

Abhishek007p, Thank you very much for helping me.

abhishek007p · Feb 8, 2018

first make a sample admob example for testing. once you can see the test ads, you integrate the code into your main project.

you need to login to admob and start a new ad project and get json file and ad-id that you can use. you dont need to upload the app first.

adding ads should be done at the last steps, so unless you have a app ready, dont be in a hurry in adding ads.

kisoft · Feb 9, 2018

The test ad is already working.

kisoft · Feb 10, 2018

Success, there were no SDK packages. After installing the packages everything works fine
