【问题描述】：

我学习 android 应用程序开发已经有一段时间了，我遇到了这个烦人的错误，我的应用程序在我的设备上运行时崩溃（Mi a1、android 9、API 28）。我没有对原始代码做任何更改，只是在适当的地方输入了我的api。

AndroidManifest.xml

    <!--

         location permissions for the 'MyLocation' functionality.

             The API key for Google Maps-based APIs is defined as a string resource.

             Note that the API key is linked to the encryption key used to sign the APK.
             You need a different API key for each encryption key, including the release key that is used to
             sign the APK for publishing.
             You can define the keys for the debug and release targets in src/debug/ and src/release/.

TODO: Before you run your application, you need a Google Maps API key.

To get one, follow this link, follow the directions and press "Create" at the end:

https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=D0:2E:31:27:4F:07:82:C0:F9:CD:5F:14:70:FF:28:CB:29:85:5A:CE%3Bcom.example.googlemapdemo

You can also add your credentials to an existing key, using these values:

Package name:
D0:2E:31:27:4F:07:82:C0:F9:CD:5F:14:70:FF:28:CB:29:85:5A:CE

SHA-1 certificate fingerprint:
D0:2E:31:27:4F:07:82:C0:F9:CD:5F:14:70:FF:28:CB:29:85:5A:CE

Alternatively, follow the directions here:
https://developers.google.com/maps/documentation/android/start#get-key

Once you have your key (it starts with "AIza"), replace the "google_maps_key"
string in this file.

请帮忙。

【问题讨论】：

你能显示来自 LogCat 的错误信息吗

很抱歉，我在这里添加了错误信息。

【参考方案1】：

LogCat 有错误，

classnotfoundexception: 没有找到类 "org.apache.http.ProtocolVersion"

搜索那个错误会显示很多这样的结果，试试这个，这可能会解决错误，将它添加到你的 Androidmanifest.xml

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

【参考方案2】：

您是否忘记添加包名：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools"
          package="com.example.googlemapdemo">

    <application
        android:allowBackup="false"

.....

【讨论】：

软件包名称在清单中，如果我没有在问题中发布它，我会犯错误，对不起。我更新了问题中的清单。你介意再看一遍吗？
