我在我的应用程序中使用google map api。该地图运行正常，但现在它一片空白.Map仍在工作但未加载地图。我正在搜索答案几个小时，但未得到任何结果。在Google云端平台上创建了一个新的api，并放置了该api，但仍未加载地图。 任何可以帮助我的人。谢谢！
这是空白地图的屏幕截图。 Screenshot of map

制作新应用。一个星期前，我在两天后制作了一个webview应用，但webview没有加载任何内容，因此请新建一个。
答案 1 :(得分：0)
确保已启用“ Google Maps Android API v2”。
确保存在以下Android密钥：
更新1
07-21 21：28：59.573 18146-18265 / com.example.har.firebaseauthenticationdemo E / Google地图 Android API：授权失败。
请参见https://developers.google.com/maps/documentation/android-api/start，了解如何正确设置地图。

更新3
获取SHA1以用于生成API密钥
macOS和Linux：
~/.android/
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
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，您可以找到所有应用程序签名信息，而无需任何控制台命令：
答案 2 :(得分：0)
1。获取Google Maps API密钥
https://developers.google.com/maps/documentation/android-sdk/signup?authuser=1
2。将此API密钥放置在strings.xml或Android Manifest中
AndroidManifest.xml
<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。将SupportMapFragment放入所需的xml
<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" />
