Android 9 Pie崩溃（com.google.android.gms ... ClassNotFoundException）

问题描述 投票：13回答：1

我在Android上发布了Unity3D游戏，到目前为止它运行良好。但是，Android Vitals Dashboard现在报告了很多崩溃事件。这是详细信息：

By Android version: Android 9   4500    100.0%

堆栈跟踪：

Target API level: 28
Minimum API level: 16

我在Google AdMob's discussion group中看到过类似的线程，建议将以下内容添加到AndroidManifest.xml文件中：

<uses-library android:name="org.apache.http.legacy" android:required="false" />

然而：

  1. 我不确定问题是由任何与apache相关的API引起的。
  2. 我担心这会限制我的应用中的安装次数，因为由于uses-library声明，它可供Google Play中的较小受众使用。

根据Behavior changes: apps targeting API level 28+

Apache HTTP客户端弃用

在Android 6.0中，我们删除了对Apache HTTP客户端的支持。从Android 9开始，该库将从bootclasspath中删除，默认情况下不可用于应用程序。要继续使用Apache HTTP客户端，针对Android 9及更高版本的应用可以将以下内容添加到其AndroidManifest.xml：

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

注意：最低SDK为23或更低的应用程序需要android：required =“false”属性，因为在API级别低于24的设备上，org.apache.http.legacy库不可用。 （在这些设备上，Apache HTTP类在bootclasspath上可用。）

作为使用运行时Apache库的替代方法，应用程序可以在其APK中捆绑自己版本的org.apache.http库。如果这样做，则必须重新打包库（使用Jar Jar之类的实用程序）以避免与运行时中提供的类的类兼容性问题。
