Target API level: 28
Minimum API level: 16

我在Google AdMob's discussion group中看到了类似的线程，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" />

但是：

我不确定问题是否是由任何与Apache相关的API引起的。
由于uses-library声明，由于它会在Google Play中提供给较小的受众群体，因此这会限制我的应用中的安装次数。

按照 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，该库已从   bootclasspath，默认情况下不适用于应用程序。要继续使用Apache HTTP客户端，面向Android 9及更高版本的应用可以在其AndroidManifest.xml中添加以下内容：

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

注意：对于具有以下功能的应用，需要android：required =“ false”属性   最低SDK为23或更低版本，因为在具有API级别的设备上   低于24，则org.apache.http.legacy库不可用。   （在这些设备上，Apache HTTP类在   bootclasspath。）

作为使用运行时Apache库的替代方法，应用程序可以捆绑   APK中他们自己的org.apache.http库版本。如果你   为此，您必须重新打包该库（使用Jar Jar之类的实用程序）   为避免与   运行时。
