Answer 1:

确保“谷歌地图API的Android V2”已启用。

• 转到谷歌控制台 API和搜索地图Android版的API。 并确保已启用它。

确保以下的Android项是否存在：

• 转到谷歌控制台凭据管理器。 然后加入Android API密钥用于调试和发布。 检查谷歌文件的更多细节。

更新1

• 从您的logcat的。

07-21 21：28：59.573 18146-18265 / com.example.har.firebaseauthenticationdemo E /谷歌地图API的Android：授权失败。

请参阅https://developers.google.com/maps/documentation/android-api/start对于如何正确设置地图。

更新2

的build.gradle

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            resValue "string", "google_maps_api_key", "Release_API_KEY"
        }
        debug {
//          KL MBP debug Key
            resValue "string", "google_maps_api_key", "DEBUG_API_KEY"
//          KL Old Machine debug Key
//            resValue "string", "google_maps_api_key", "DEBUG_API_KEY"
        }
    }

AndroidManifest.xml中

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

    <uses-library
        android:name="com.google.android.maps"
        android:required="true" />

更新3

获得SHA1对生成API密钥使用

• 对于Linux或者MacOS，打开一个终端窗口，输入以下命令：

MacOS和Linux上： ~/.android/

 keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android 

• 对于Windows Vista和Windows 7，运行：

Windows Vista和Windows 7：

C:\Users\your_user_name\.android\ List the SHA-1 fingerprint:

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

在Android Studio中，你可以找到没有任何控制台命令所有你的应用程序签名信息：

1. 打开项目
2. 从右侧面板中点击摇篮
3. 在摇篮工程面板打开文件夹：你的项目 - >任务 - > Android的
4. 运行signingReport任务（双击），你会看到在摇篮控制台中的结果（密钥存储路径，SHA1，MD5等）。

Answer 2:

结交新app.A星期前我做了2天之后的WebView网页视图的应用程序时不会加载任何umntil做出新的一个。

Answer 3:

1.Get谷歌地图API密钥

https://developers.google.com/maps/documentation/android-sdk/signup?authuser=1

2.Place无论是在strings.xml中或Android清单此API密钥

AndroidManifest.xml中

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

string.xml

<string name="google_maps_key">YOUR_API_KEY</string>

3.Put SupportMapFragment你希望XML中

<fragment
   android:id="@+id/placesMap"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:layout_marginTop="8dp"
   android:layout_marginBottom="8dp"
   android:tag="@string/tag_places_search_map"
   class="com.google.android.gms.maps.SupportMapFragment" />
