Trying to build apk i receive this error:

Note: /home/luca/.pub-cache/hosted/pub.dartlang.org/apn_fb_login-0.0.4/android/src/main/java/com/appnormal/plugin/fblogin/ApnFbLoginPlugin.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':apn_fb_login:verifyReleaseResources'.
> com.android.builder.internal.aapt.AaptException: Failed to compile file /home/luca/IdeaProjects/shuttertop/build/apn_fb_login/intermediates/res/merged/release/layout-v26
