android - 我试图将我的 Android 应用程序连接到 google firebase，但它显示错误

Question

我尝试将我的应用程序连接到 google firebase，我按照程序在 Gradle 和 JSON 文件中实现。之后，我尝试运行我的应用程序并显示以下错误消息:



这是我的 Gradle 文件:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

    buildscript {
        repositories {
            google()
            jcenter()

        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.5.3'
            classpath 'com.google.gms:google-services:4.3.3'
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }

    allprojects {
        repositories {
            google()
            jcenter()

        }
    }


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

这是我的另一个 Gradle 模块:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"
    defaultConfig {
        applicationId "com.example.ius"
        minSdkVersion 15
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'androidx.navigation:navigation-fragment:2.0.0'
    implementation 'androidx.navigation:navigation-ui:2.0.0'
    implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0'
    implementation 'com.google.firebase:firebase-analytics:17.2.2'
    implementation 'com.google.firebase:firebase-auth:19.2.0'
    testImplementation 'junit:junit:4.12'
    implementation 'com.android.volley:volley:1.1.0'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

如果你能帮助我，那对我来说就意味着整个世界。提前致谢

更改您的 minSdkVersion 15至minSdkVersion 16
作为Docs表示

Make sure that your app meets the following requirements: Targets API level 16 (Jelly Bean) or later
