Question

我的代码有问题。

到目前为止，我使用Eclipse，但现在我使用的是Android Studio。

（在Eclipse中）我有一个名为 MoST 的图书馆计划，需要 google_play_service_r16 图书馆计划。要在Android Studio中导入此项目：

1）在Eclipse中，我将google_play_service_r16添加到MoST。

2）将文件导出为 build.gradle 。

3）最后我导入了build.gradle，然后在Android Studio中创建 MoST.aar 。

在Android Studio中，我创建了一个使用MoST模块的新项目。当我尝试运行我的新应用程序时，我有这个错误：

错误说 大部分都没有找到课程＆＃34; com.google.android.gms.common.GooglePlayServicesClient $ ConnectionCallbacks＆＃34;

我该如何解决这个问题？

Answer 1

<强>解

GooglePlayServicesClient类已弃用一段时间了。最新版本的Google Play服务（如10.2.1）可能会产生各种问题。在我的情况下，我不能使用较新的版本，因为我无法直接编辑库。要解决这个问题已经包含谷歌播放服务版本4.3.23，其中包括GooglePlayServiceClient，我解决了这个问题。 AndroidManifest.xml（最终）：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
