        }
    }
    sourceSets {
        main {
            jniLibs.srcDir 'src/main/libs'
            jni.srcDirs = [] // レガシー ndk-build サポートを無効にする

    }
}

allprojects {
    repositories {
        mavenCentral()
        google()
        maven { url "https://maven.google.com" }
        jcenter()
        maven { url "https://maven.google.com" }
    }
}

any help is appreciated , thanks in advance

Answer 1

Remove these lines and delete these jar files

compile files('libs/nineoldandroids-2.4.0.jar')
compile files('libs/support-v4-19.0.1.jar')

Your compileSdk is set to 27, not 19, and NineOldAndroids is a deprecated library for several years

You should also find the proper implementation dependencies for javax.inject and dagger rather than using jars

You can also remove these repos as jcenter includes Maven Central

mavenCentral()
maven { url "https://maven.google.com" }
maven { url "https://maven.google.com" }
