Android Question Object reference not set to an instance of an object.

[hookshy]

I can not user my project as for new app , I do not know what shall i do next.
I changed the package name from tools builder options and does not allow me to run due to this object reference not set to an instance of an object

I have downloaded new dexer available and added #MultiDex: True
Now I have to think what to do to fix this....

Is this a bug from the new Ide 7.8 ?
If I change the build name and keep the package name it works ok ...the problem is when I change the package from build tools ...and I do want to publish more apps in the future
thanks

No need to download any dexer if you are using the latest version of B4A.

My guess is that your manifest code calls:

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

The package name in the json file must match the project package name.

My guess is that your manifest code calls:

Yes ...this might be it
I do have done a mistake by adding firebase with a sdk for a specific package name ...let me modify

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

The package name in the json file must match the project package name.

it works now .... thanks

fixed by replaceing the write google-services.json.. the old one was pointing to wrong package name ...
