相关疑难解决方法(0)

我正在尝试通过Firebase在我的Android应用中实施Google登录,并且在我的Gradle同步后,以下消息仍然显示:

错误:任务':app:processDebugGoogleServices'的执行失败.请通过更新google-services插件的版本来修复版本冲突(有关最新版本的信息,请访问https://bintray.com/android/android-tools/com.google.gms.google-services/)或将com.google.android.gms的版本更新为10.2.6.

我该如何解决这个错误？

这是我的Gradle文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

        versionName "1.0.1"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {

    }
    sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/2'] } }
}
