Question

我知道这个问题被问了几十次，但我仍然无法解决问题这是我的清单文件

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

        </activity>

        <meta-data

            android:label="@string/title_activity_maps" >
        </activity>

    </application>

</manifest>

这是我的google_maps_api.xml

<resources>
    <!--
    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=FC:78:21:3D:9E:21:BA:03:0E:0E:E0:C9:7D:C7:65:45:A4:9D:DA:8B%3Bchatapps.tutorial.com.fatimaarshad_assignment2

    You can also add your credentials to an existing key, using this line:
    FC:78:21:3D:9E:21:BA:03:0E:0E:E0:C9:7D:C7:65:45:A4:9D:DA:8B;chatapps.tutorial.com.fatimaarshad_assignment2

    Once you have your key (it starts with "AIza"), replace the "google_maps_key"
    string in this file.
    -->
    <string name="google_maps_key" translatable="false" templateMergeStrategy="preserve">
     AIzaSyCshw8btydSGdry5SqJOgX7vdojQnMvv-Q
    </string>
</resources>

我已经添加了所有权限和api密钥，两次更改了api密钥但它仍然无法正常工作。它之前确实有效，但它不再起作用了。
