Compile error when try to use firebase::database::Database

[althurzard]

My project uses firebase auth, database. When i tried to call the entry point for the Firebase Realtime Database C++ SDK, something like that auto database = ::firebase::database::Database::GetInstance(firebase::App::GetInstance());

I should get these errors when compile on android

If i comment out that line, everything goes right.

Just found the issue. I had to downgrade target version from 23 to 22 cocos compile -p android --ap android-22 --android-studio.

[formatCvt]

what version of firebase sdk do you use?

[althurzard]

@formatCvt Lastest version I could build project by using api android 22 or 24, but 23 should get that errors above.

[stewartmiles]

@althurzard are you still seeing an issue?

[Solman28]

I get the same error, Somebody found the bug?

[althurzard]

@stewartmiles i solved it. Just change to api android 22 or 24.

[Solman28]

Yes! I solved it using a Smartphone with android 5.1+

[delorenj]

I tried changing to android 24 and the problem was not resolved =(

Ok, finally figured it out. The issue was the order of the linking:

This produced the above error:

LOCAL_STATIC_LIBRARIES := cocos2dx_static \
firebase_app \
firebase_analytics \
firebase_auth \
firebase_database

And this resulted in a successful build:

LOCAL_STATIC_LIBRARIES := cocos2dx_static \
firebase_analytics \
firebase_auth \
firebase_database \
firebase_app
