Question

我将我的项目与firebase广告相关联，而且我无法使用AdView，MobileAds等课程。它显示无法解析符号（建议：添加库＆＃39; play-services-ads-lite：11.2.0＆＃39;到classpath）。我从android studio直接连接了firebase。这是我的两个渐变。

Answer 1

就像您的问题所说，将此添加到build.gradle（app）

boost::optional<const char *> foo () {
   char ar[100] = {};
   return boost::make_optional(true, ar);
}

希望这有帮助！

Answer 2

在根build.gradle文件中添加Google的Maven存储库，这是所有模块的

repositories {

     mavenLocal()
     mavenCentral()
     maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
     maven { url "https://oss.sonatype.org/content/repositories/releases/" }
     maven {  url "https://maven.google.com" }   //<-- Google's Maven repository
}

之后在Android模块中注入Ads依赖

dependencies {
    compile 'com.google.firebase:firebase-ads:11.2.0'
}

刷新您的项目。
