Default FirebaseApp failed to initialize because no default options were found

Hey,

I've forked your project, removed everything except analytics and authentication, rebuild it and exported my godot project. The export itself succeeds, but the app crashes on startup:

Note: google-services and firebase plugin json files are included in the export per instructions

I followed all the steps in your instruciton, especially adding dep to google-services and applying google-services plugin in android/build/build.gradle:

sed "/^\/\/CHUNK_BUILDSCRIPT_DEPENDENCIES_BEGIN.*/a classpath 'com.google.gms:google-services:4.3.3'" -i android/build/build.gradle
sed "/^\/\/CHUNK_GLOBAL_BEGIN.*/a apply plugin: 'com.google.gms.google-services'" -i android/build/build.gradle

This results in:

Not sure if it's relevant, but after successful export, the apply plugin google-services is missing from build.gradle (along with some other stuff too):

I've run out of ideas. Does this ring a bell? What should I double-check next?

Hi,

all your manual additions should be before or after the.. _BEGIN /_END stuff (CHUNK_BUILDSCRIPT_DEPENDENCIES_BEGIN, etc). These lines are "left overs" from the previous (deprecated) build system. (At least they are not documented for the new v1 plugin build system.)

I hope this was helpful.

[myood]

Yes, did the trick! Thanks!

Your instructions are correct, only these legacy parts a little misleading. A little improvement for consideration - maybe you could emphasize putting them above a little more with explanation to ignore _BEGIN/_END stuff?

Correct sed invocation, for the record:

sed "/^\/\/CHUNK_BUILDSCRIPT_DEPENDENCIES_BEGIN.*/i classpath 'com.google.gms:google-services:4.3.3'" -i android/build/build.gradle
sed "/^\/\/CHUNK_GLOBAL_BEGIN.*/i apply plugin: 'com.google.gms.google-services'" -i android/build/build.gradle

Cool :-)
