Android 添加admob ads库后，混合版本可能导致运行时崩溃

我知道有很多这样的问题，但没有找到任何一个与Admob广告相关的问题，我只想在我的应用程序中使用Admob广告，我在官网

implementation'com.google.android.gms:play services ads:15.0.0'

中添加了广告相关

但给了我一个警告：

All gms/firebase libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 15.0.1, 15.0.0. Examples include com.google.android.gms:play-services-ads-identifier:15.0.1   and com.google.android.gms:play-services-ads:15.0.0 less... (Ctrl+F1) 
There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)

我只想在没有firebase的情况下使用ads依赖项。

检查你的应用程序gradle文件，你的依赖项有冲突。更新以下内容

com.google.android.gms:play-services-ads:15.0.1

我只使用了_com.google.android.gms:play services ads:15.0.1 _其他依赖项与google-services-ads冲突。请复制并粘贴所有依赖项。'com.android.support.constraint:constraint布局：1.1.0''com.google.android.gms:play services ads:15.0.0''com.android.support:appcompat-v7:27.1.1''com.google.android.gms:play services ads:15.0.0''com.android.support.test:runner:1.0.2''com.android.support.test.espresso:espresso core:3.0.2'好的，我看到您添加了两次'com.google.android.gms:play services ads:15.0.0'，只添加一次，删除重复项。同时将gms:play-services-ads的15.0.0更新为15.0.1。或者复制以下行“com.google.android.gms:play-services-ads:15.0.1”，这应该可以解决问题。
