我正在使用 Jetpack Compose 并尝试将 Google 地图集成到我的应用程序中。我已按照文档设置API key。但是，在构建项目时出现错误。在我的local.properties 文件中，我有以下代码：

MAPS_API_KEY=my_api_key

在我的androidManifest.xml 上，我有以下代码：

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/Theme.GuideMeTravelersApp">
    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="$MAPS_API_KEY" />
    <activity
        android:name=".homescreen.HomeScreen"
        android:exported="true"
        android:label="@string/title_activity_home_screen"
        android:theme="@style/Theme.GuideMeTravelersApp.NoActionBar" />
    <activity
        android:name=".registerview.RegisterView"
        android:exported="true"
        android:label="@string/title_activity_register_view"
        android:theme="@style/Theme.GuideMeTravelersApp.NoActionBar" />
    <activity
        android:name=".ExperienceDetailsView.ExperienceDetailsActivity"
        android:exported="true"
        android:label="@string/title_activity_experience_details"
        android:theme="@style/Theme.GuideMeTravelersApp.NoActionBar" />
    <activity
        android:name=".LoginView.LoginActivity"
        android:exported="true"
        android:label="@string/title_activity_login"
        android:theme="@style/Theme.GuideMeTravelersApp.NoActionBar" />
    <activity
        android:name=".MainActivity"
        android:exported="true"
        android:label="@string/app_name"
        android:theme="@style/Theme.GuideMeTravelersApp.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

但是，这似乎还不够，因为我在构建项目以查看预览时收到以下错误：

java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml does not exist.

当我检查local.properties 文件时，它会警告我MAPS_API_KEY 未使用。我不确定如何使用它。我按照文档中的说明进行操作，但它不起作用。对于地图代码，我正在尝试将Crane sample 调整到我的项目中，该项目有一个谷歌地图。

【问题讨论】：

@TicherhazFreePalestine 是的，我已经完成了这些步骤。我有一个帐户并且我已经获得了我的 API 密钥，我将 my_api_key 放在 *** 上，以免共享我的实际 API 密钥。你把meta-data放在正确的地方了吗？ @TicherhazFreePalestine 是的，在应用程序标签下，对吗？我添加了 AndroidManifest.xml 的全部代码 【参考方案1】：

将此添加到您的应用模块的build.gradle，在defaultConfig 闭包中：

android 
    ...

    defaultConfig 
        Properties properties = new Properties() 

        properties.load(project.rootProject.file('local.properties').newDataInputStream())
        manifestPlaceholders = [MAPS_API_KEY: "$properties.getProperty('MAPS_API_KEY')"]
    ...

并在清单中添加此元数据：

<meta-data
   android:name="com.google.android.gms.version"      
   android:value="@integer/google_play_services_version" />

Here 是 Github 上的一个项目示例。

在 android 部分下？ @sitatech 不幸的是，它没有解决错误，我仍然在local.properties 文件中收到警告:( @sitatech 该异常是由于缺少 google play services 版本元数据引起的，将其添加到您的清单中应该可以解决。添加元数据后尝试清理您的项目和 Gradle 缓存，然后重新构建它。 local.properties 中的警告不会消失，因为您没有在应用程序中直接引用 MAPS_API_KEY（您不能），您正在使用 Property 实例来加载它（您添加到 build.gradle 的代码。该警告不会导致您的应用崩溃。无论如何，祝您好运。兄弟，这几乎在日志中给出。如果您阅读它们
