Android Build Failed - No signature of method

[Kang-Kim1]

The following error occurs when trying to build or run my flutter project on Android device :

FAILURE: Build failed with an exception.

* Where:
Build file '{~~~}/.pub-cache/hosted/pub.dartlang.org/appsflyer_sdk-6.12.2/android/build.gradle' line: 17

* What went wrong:
A problem occurred evaluating project ':appsflyer_sdk'.
> No signature of method: build_4ozmr53o1s07jb7newqa4ny7n.android() is applicable for argument types: (build_4ozmr53o1s07jb7newqa4ny7n$_run_closure2) values: [build_4ozmr53o1s07jb7newqa4ny7n$_run_closure2@287d5ae1]

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Additional info :

• Gradle version: distributionUrl=https\://services.gradle.org/distributions/gradle-6.9.2-bin.zip
• Flutter version: 3.3.1

I spent 2 whole days to resolve the issue but no luck so far,,,
(It seems not many people are struggling with the same issue..)

I would be so glad if anyone can share some valuable knowledges to resolve this type of exception...

Please let me know if any further information is needed!
Thanks.

I have the same issue above

I solved it by using the version
appsflyer_sdk: 6.11.3

[YuWenHaoqq]

I solved this problem
flutter_3.0.5/.pub-cache/hosted/pub.dartlang.org/flutter_facebook_auth-5.0.11/android/build.gradle
Delete the namespace in this file and add it to flutter_3.0.5/.pub-cache/hosted/pub.dartlang.org/appsflyer_sdk-6.13.2/android/src/main/AndroidManifest.xml
Add package in
