注意: 确保在AndroidManifest.xml文件的元素中包含元素。

我尝试更改了API密钥，但仍然收到相同的错误消息。

有什么想法可以解决这个问题吗？

请查看下面的代码：

你添加了API密钥吗？my_api_key的值是什么？ - salih

我在https://console.developers.google.com/上获得的“API密钥”@salih - gon250

显然不是这个问题，但在多次着陆此帖子和类似页面寻找类似问题的答案后，我发现自己犯了一个愚蠢的错误，没有注意到我把<meta-data>标签放在了<application>...</application>之外。 - ArtiomLK

Answer 1

您的错误提示是这样的：

Caused by: java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

我认为你应该为你的项目添加API密钥。你必须添加调试API密钥。

首先，在values目录下创建xml文件，命名为google_maps_api。添加以下代码片段：

<string name="google_maps_key" translatable="false" templateMergeStrategy="preserve">
    YOUR API KEY HERE!!!
</string>

你的清单必须像下面这样：

并且你的清单必须如下所示：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="company.mapapp">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <!--
 The ACCESS_COARSE/FINE_LOCATION permissions are not required to use
         Google Maps Android API v2, but are recommended.
    -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        android:logo="@drawable/male80">
        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />


        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="@string/google_maps_key" />


        <activity
            android:name="company.mapapp.SplashActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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


        <activity android:name=".MainActivity" />



    </application>

</manifest>

我必须使用“值目录上的xml文件”吗？因为我一直得到相同的错误。 - God

Answer 2

如果错误原因相同，请检查您是否在 /console.developers.google.com 启用了正确的 "Google Maps Adroid Api" API 密钥。
