清单合并失败:uses-sdk:minSdkVersion 15 不能小于库中声明的版本 16

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library

当我尝试构建 apk 时,出现此错误:

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.google.firebase:firebase-messaging:19.0.1] C:\Users\taha\.gradle\caches\transforms-2\files-2.1\eff6e7bdbf3eaa269c101b27c652fb15\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.messaging" to force usage (may lead to runtime failures)

这是 gradle 构建。我尝试将 SDK 版本从 27 更新到 28,但没有成功:

android {
compileSdkVersion 27
defaultConfig {
    applicationId ''

    minSdkVersion 15
    targetSdkVersion 27
    versionCode 1
    versionName "1.0.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
productFlavors {
}

}

    implementation fileTree(include: ['*.jar'], dir: 'libs')
    testImplementation 'junit:junit:4.13-beta-3'

}

apply plugin: 'com.google.gms.google-services'

根据 Google Play services blog post,Google Play 服务和 Firebase,包括 com.google.firebase:firebase-messaging 库已移至 minSdkVersion 16。您需要更改您的 minSdkVersion 到 16 或移回所有库的旧版本。
