【问题描述】：

当我尝试构建 apk 时，我收到此错误：

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)

这里是 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 {
}

}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    testImplementation 'junit:junit:4.13-beta-3'
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.android.support:palette-v7:27.1.1'
    implementation 'com.android.support:recyclerview-v7:27.1.1'
    implementation 'com.balysv:material-ripple:1.0.2'
    implementation 'com.google.android.gms:play-services-ads:18.0.0'
    implementation 'com.google.firebase:firebase-core:17.0.0'
    implementation 'com.google.firebase:firebase-messaging:19.0.1'
    implementation 'com.squareup.picasso:picasso:2.71828'
    implementation 'com.onesignal:OneSignal:3.10.9'
    implementation 'com.google.android.ads.consent:consent-library:1.0.7'
}

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

【解决方案1】：

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，共 16 个。您需要将 minSdkVersion 更改为 16 或移回旧版本所有库的版本。
