Answer 1

这里是官方文档

If you are using com.google.android.gms:play-services-maps:16.0.0 or below and your app is targeting API level 28 (Android 9.0) or above, you must include the following declaration within the element of AndroidManifest.xml.

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

This is handled for you if you are using com.google.android.gms:play-services-maps:16.1.0 and is not necessary if your app is targeting a lower API level.

同时在 Menifest.xml 中添加这个标签

<application
.....
.....
android:usesCleartextTraffic="true">

如果您使用向服务器发送和接收请求(如 Volley、改造和 Http 请求)

也试试这个(可选)

将项目转换为AndroidX确保首先备份项目。
