Android ERROR : minSdkVersion 오류

Android ERROR 내용

 

ERROR: Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.google.firebase:firebase-iid:20.0.2] C:\Users\GP\.gradle\caches\transforms-2\files-2.1\946a39d7756c6b05aa38a853bdffc128\firebase-iid-20.0.2\AndroidManifest.xml as the library might be using APIs not available in 15

           Suggestion: use a compatible library with a minSdk of at most 15,

                      or increase this project's minSdk version to at least 16,

                      or use tools:overrideLibrary="com.google.firebase.iid" to force usage (may lead to runtime failures)

 

 

원인 : minSdkVersion 설정이 잘못되어 있었다.

 

해결방법 : app 단의 build.gradle 파일에서 minSdkVersion을 변경하면 된다.

              오류에서 15로 설정하라고 알려주기때문에 15로 변경하면된다.
