Question

尝试全屏加载Google地图时遇到问题。我已经关注了pub.dartland.org中所有有关map_view的文档：

在我的AndroidManifest.xml中，

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

还添加了：

 <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your_api_key"/>
 <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>

当然更改了apiKey，并且：

<activity android:name="com.apptreesoftware.mapview.MapActivity" android:theme="@style/Theme.AppCompat.Light.DarkActionBar"/>

我还在build.graddle中添加了kotlin依赖项。因此，现在我可以在设备上看到staticUri地图，很好，但是当我点击此地图以全屏显示时，应用程序因以下错误而崩溃：

D/AndroidRuntime( 4373): Shutting down VM
E/AndroidRuntime( 4373): FATAL EXCEPTION: main
E/AndroidRuntime( 4373): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.apptreesoftware.mapview.MapActivity}: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class fragment

E/AndroidRuntime( 4373): Caused by: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class fragment

E/AndroidRuntime( 4373): 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

我尝试添加：

<meta-data android:name="com.google.android.geo.API_KEY" android:value="xxxxxxxxxxxxxxx"/>

但同样的问题，也许有人有主意吗？

编辑：这是我的AndroidManifest.xml：

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

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

    <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="my-app"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">

            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                android:value="true" />
            <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="XXXXXXXXXXXXXX"/>
            <!-- <meta-data android:name="com.google.android.geo.API_KEY" android:value="XXXXXXXXXXXXXXXX"/> -->
            <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>       
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <activity android:name="com.apptreesoftware.mapview.MapActivity" android:theme="@style/Theme.AppCompat.Light.DarkActionBar"/>

    </application>
</manifest>

好的，您需要将google maps元数据移到activity标签之外，如下所示：

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

            <uses-permission android:name="android.permission.INTERNET"/>
            <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
            <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

            <application
                android:name="io.flutter.app.FlutterApplication"
                android:label="my-app"
                android:icon="@mipmap/ic_launcher">


                    <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="XXXXXXXXXXXXXX"/>
                    <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/> 

                <activity
                    android:name=".MainActivity"
                    android:launchMode="singleTop"
                    android:theme="@style/LaunchTheme"
                    android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density"
                    android:hardwareAccelerated="true"
                    android:windowSoftInputMode="adjustResize">

                    <meta-data
                        android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                        android:value="true" />
                    <intent-filter>
                        <action android:name="android.intent.action.MAIN"/>
                        <category android:name="android.intent.category.LAUNCHER"/>
                    </intent-filter>
                </activity>
                <activity android:name="com.apptreesoftware.mapview.MapActivity" android:theme="@style/Theme.AppCompat.Light.DarkActionBar"/>

            </application>
        </manifest>

总而言之，元数据与父组件有关，因此在这种情况下，您需要用于所有应用程序的元数据，而不仅仅是用于一项活动：）。
