问题描述
我目前对此问题感到困惑:Google Maps似乎根本没有加载.请参见下图:
I am currently stuck with this problem: Google Maps seems not to be loading at all. Please see the image below:
这真的使我发疯.我已经做过以下事情:
This is really driving me crazy. I already have done the following:
- 将我的软件包名称+ SHA1(调试密钥库)+ SHA1(发行密钥库)添加到Google Developer的控制台中.
- 已启用Android的Maps SDK. API密钥具有Android应用限制
- 从Firebase控制台将google-services.json添加到我的应用中
- 添加了必要的权限:
- 将API密钥添加到清单文件中-从Google Developer Console中
- 为gms版本添加了元数据
- Added my package name + SHA1 (debug keystore) + SHA1 (release keystore) to Google Developer's console.
- Maps SDK for Android is enabled. The API key has Android app restriction
- Added google-services.json to my app from Firebase console
- Added necessary permissions:
- Added API Key to the Manifest file - from Google Developer Console
- Added meta data for gms version
这是我片段的代码:

return;
}
googleMap.setMyLocationEnabled(true);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(augsburg, 13));
googleMap.addMarker(new MarkerOptions()
.title("Augsburg Zoo")
.snippet("Der coolste Zoo der Welt")
.position(augsburg));
}
}
这是我的布局代码:
<?xml version="1.0" encoding="utf-8"?>

<TextView

android:layout_centerInParent="true"
android:text="Coming soon!"
android:textColor="@color/colorPrimary"
android:textSize="30sp"
android:visibility="invisible" />
</RelativeLayout>
谁能告诉我我还缺少什么?
Can anyone tell what still I'm missing?

请注意，当我对其他地图项目使用相同的API_KEY时，它可以正常工作.该地图似乎没有显示在我的应用程序上，但正在其他项目上运行.
Please note that when I use the same API_KEY to other map projects, it is perfectly working. It seems that the map is not showing on my app but working on other projects.

推荐答案
昨天我在设计公司的客户时遇到了这个问题.与我背后的客户一起解决问题，这是疯狂的两天.我所做的是:
I had this problem yesterday in designing a customer in the company. it was two crazy days to work it out with the customer behind me. What I did was:
-
从Google Dashboard API删除当前密钥(API密钥). 从Google仪表板API中删除Firebase Web密钥.创建一个 新的Android密钥API，注册SHA-1和程序包名称.和 在项目android studio中添加；
Delete the current key (API Key) from the Google Dashboard APIs. Delete the firebase web key from the Google dashboard APIs. Create a new Key API for android, register the SHA-1 and package name. and add in project android studio;
在FIrebase项目中，删除SHA-1代码以再次添加.下载 google-services.json，然后添加项目；
In the FIrebase project delete the SHA-1 code to add again. Download google-services.json, and add in the project;
以发布模式生成应用，在商店中发布并下载 在某些设备上，运行应用程序时应正常显示地图；
Generate the app in release mode, publish in the store, and download on some device, when running the app should show the Map normally;
如果没有，它将向您显示LogCat中的错误，表示您必须 注册以下SHA-1密钥: XXXXXXXXXXXXXXXXX 和程序包 名称:com.your.packagename;
If not, it will show you the error in LogCat, saying that you must register the following SHA-1 key: XXXXXXXXXXXXXXXXX and the package name: com.your.packagename;
只需在Google API中注册此密钥，即可在少数几个版本中使用 秒，甚至无需更新商店中的应用程序.
Just register this key in Google APIs, and it will work in a few seconds, without even having to update the app in the store.
注意:另一件事，请考虑升级Google Maps和Google Services的依赖项.
NOTE: Another thing, consider upgrading the dependencies of Google Maps, and Google Services.
希望这会有所帮助.
