在IntelliJ IDEA的与gradle这个播放服务：没能解决：com.google.android.gms

I just replaced version 11.2.0 with 11.0.0 and then it seemed to work fine, so that had to mean that 11.2.0 wasn't included with the latest Android SDK.

So, after struggling with all the available scattered documentation, I reached this document by pure chance (I guess it is not indexed high enough by Google): https://developers.google.com/android/guides/releases

I quote from there:

Highlights from the Google Play services 11.2 release. Google Play services dependencies are now available via maven.google.com

Now, even when that shouldn't necessarily mean that they are not available with the downloaded SDK anymore, it seems that this is actually the case.

Anyway, adding google() to my build.gradle didn't work (not found, undefined, or whatever...), so I used a different approach that I found in this document referenced from the previous one:

https://developer.android.com/studio/build/dependencies.html#google-maven

I modified my build.gradle file adding that line to allprojects/repositories, as in:

allprojects {
...
    repositories {
...
        maven { url "https://maven.google.com/"}
    }
}

And then also in the android section in the same build.gradle file:

project(":android") {
...
    dependencies {
...
        compile 'com.google.android.gms:play-services-ads:11.2.0'
    }
}

Those two lines were enough to make Gradle sync without problems. I didn't need to add any plugins apart from the ones that are already added in my libGDX project by default.

After that, I got a few different errors, but none about Gradle or dependencies. In a brief, JFTR:

First, I had a minSdkVersion of 8. Solved by raising it to 14. I think I could live without supporting all those devices below 14.

Second, I had problems with the dex upper limit of references. I've never faced this problem before, but maybe you've already noticed the solution I used: instead of compiling the whole 'com.google.android.gms:play-services' I used only 'com.google.android.gms:play-services-ads' that's the API I'm actually interested right now. For those other particular cases where a solution like this may not be useful, this document could provide some better insight: https://developer.android.com/studio/build/multidex.html

Third, even after that I got this "jumbo" thing problem described and answered here: https://stackoverflow.com/a/26248495/1160360

And that's it. As of now, everything builds and my game does finally shows those Admob banners.

我花了几个小时与此，心想，这使我怀疑，如果所有我们使用这些最近的楼宇自动化系统是值得的额外负担，他们补充。

我的意思是，我第一次与AdMob五年前左右添加到应用程序，我只是下载一个.jar文件，并把它放在我的项目的目录。这是相当明显的，整个过程中，从谷歌上搜索“在我的Android项目如何设置AdMob联播”有我的应用中展示AdMob广告旗帜把我仅有几分钟的路程。我要离开这里，因为这是不适合这类辩论的地方。

尽管如此，我希望我自己的经验是有用的人别人更远。
