Manifest合併失敗：最小sdkversion 11不能小於庫[com.google.firebase：firebase-core：11.0.4]中聲明的版本14

Question

我只在我的build.gradle中添加Firebase並將其設置爲更新。顯示的minsdk 11同步錯誤不能低於14在庫中聲明。我的build.gradle依賴關係如下。 Android監視器中的構建Gradle消息中的一個建議使用工具：overrideLibrary =「com.google.firebase.firebase_core」強制使用。

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 25 
    buildToolsVersion '25.0.0' 

    defaultConfig { 
     applicationId "com.indiauthoritymarketing.instasave" 
     minSdkVersion 11 
     targetSdkVersion 23 
     versionCode 2 
     versionName "InstaSve 2.1" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

allprojects { 
    gradle.projectsEvaluated { 
     tasks.withType(JavaCompile) { 
      options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" 
     } 
    } 
} 


dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.parse.bolts:bolts-android:1.+' 
    compile 'com.parse:parse-android:1.+' 
    compile 'com.android.support:appcompat-v7:25.3.1' 
    compile 'com.android.support:design:25.3.1' 
    compile 'com.android.support:recyclerview-v7:25.3.1' 
    compile 'com.android.support:cardview-v7:25.3.1' 
    compile 'com.google.android.gms:play-services-ads:11.0.4' 
    compile 'com.mani:ThinDownloadManager:1.2.2' 
    compile 'net.rdrei.android.dirchooser:library:3.2@aar' 
    compile 'com.google.firebase:firebase-core:11.0.4' 
    compile 'com.google.firebase:firebase-auth:11.0.4' 
    compile 'com.google.firebase:firebase-messaging:11.0.4' 
    compile 'com.google.firebase:firebase-ads:11.0.4' 
    compile 'com.google.firebase:firebase-appindexing:11.0.4' 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:support-annotations:25.3.1' 
} 
apply plugin: 'com.google.gms.google-services' 

和建立依賴關係是如下所示： -

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.3' 
     classpath 'com.google.gms:google-services:3.1.0' 

    } 
} 

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 


Where I missing. 

在此先感謝。

在Android上，Firebase作爲Play服務的一部分進行分發。 Play Services現在要求使用最低API級別14。所以您必須至少將API級別設爲14。
