Google地图正在显示空白地图
Jay*_*ayo 14 android google-maps android-maps
我目前仍然遇到这个问题:谷歌地图似乎根本没有加载.请看下面的图片:
这真让我疯狂.我已经做了以下事情:
- 将我的包名+ SHA1(调试密钥库)+ SHA1(发布密钥库)添加到Google Developer的控制台.
- 启用了Maps SDK for Android.API密钥具有Android应用限制
- 从Firebase控制台添加了google-services.json到我的应用
- 添加必要的权限:
- 添加了Manifest文件的API密钥 - 来自Google Developer Console
- 添加了gms版本的元数据
这是我片段的代码:

请注意,当我对其他地图项目使用相同的API_KEY时,它完全正常工作.似乎地图没有显示在我的应用程序上,但正在处理其他项目.

昨天我在公司设计客户时遇到了这个问题.和我身后的客户一起解决这两天是疯狂的.我做的是:
从Google信息中心API中删除当前密钥(API密钥).从Google信息中心API中删除firebase网络密钥.为android创建一个新的Key API,注册SHA-1和包名.并在项目android studio中添加;
在FIrebase项目中,删除要再次添加的SHA-1代码.下载google-services.json,并添加项目;
在发布模式下生成应用,在商店中发布,在某些设备上下载,运行应用时应正常显示地图;
如果没有,它会在LogCat中显示错误,说你必须注册以下SHA-1密钥:XXXXXXXXXXXXXXXXX和软件包名称:com.your.packagename;
只需在Google API中注册此密钥,它就可以在几秒钟内完成,甚至无需更新商店中的应用.
注意:另一件事,考虑升级Google地图和Google服务的依赖关系.
希望这可以帮助.
我假设这可能是由于 SHA 1 指纹不匹配。仔细检查您是否使用相同的密钥库来获取 SHA1。
或者让我们检查您的 API 密钥是否有效。为此，添加以下 MAP_API 作为您的密钥
AIzaSyDztCvpv3PVBxzWwY7mWqCMnGfDeOiGxwY
将密钥直接添加到清单
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="AIzaSyDztCvpv3PVBxzWwY7mWqCMnGfDeOiGxwY" />
在您的 AndroidManifest.xml 中添加以下权限（可选/非必需）
<permission
android:name="your_pakage_name.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
构建你的 apk。并测试它。
如果地图显示，那么我们可以解决您的 API 密钥问题。
除此以外
也许是由于子片段管理器，所以在视图寻呼机中初始化你的片段，如下所示。然后测试一下
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="yourpackage.MapsActivity"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" />
你试过这些方法吗？
启用多索引：
https://developer.android.com/studio/build/multidex
注意：如果您的项目为 minSdkVersion 20 或更低版本的 multidex 配置，并且您部署到运行 Android 4.4（API 级别 20）或更低版本的目标设备，Android Studio 会禁用 Instant Run。
禁用即时运行：
尝试在您的onMapReady方法中添加这段代码
MapsInitializer.initialize(Objects.requireNonNull(getContext()));
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.setMyLocationEnabled(true);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(augsburg, 13));
googleMap.addMarker(new MarkerOptions()
.title("Augsburg Zoo")
.snippet("Der coolste Zoo der Welt")
.position(augsburg));
解决方案：
I had the same problem in my App so you can try this open your Android studio and
make sure you are login with the same user id of what you had created
`console.developer` account and after that you should do
SupportMapFragment mapFragment;
GoogleMap mMap;
Marker marker;
LatLng origin = new LatLng(30.5595, 22.9375);
LatLng dest = new LatLng(30.5595, 22.9375);
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.addMarker(new MarkerOptions()
.position(origin)
.title("title")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
googleMap.addMarker(new MarkerOptions()
.position(dest));
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(origin, 15));
}
