Question

我创建了一个带有Google地图活动的新Android项目。我的活动代码是：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}


/**
 * Manipulates the map once available.
 * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the camera. In this case,
 * we just add a marker near Sydney, Australia.
 * If Google Play services is not installed on the device, the user will be prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once the user has
 * installed Google Play services and returned to the app.
 */
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}

}

这是我的清单：

我得到了一个谷歌Api密钥并用sh1键限制它。我按照谷歌文档，但不幸的是我的地图没有加载。

虽然我正在搜索一些评论，建议我删除debug.keystore，但这对我不起作用。我错过了什么？

我的地图布局xml文件也是：

<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="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="ir.iuwa.testmap.MapsActivity" />

Answer 1

将此添加到应用程序标记之外的清单中并检查

<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />

Answer 2

我找到了解决方案！我错了是生成正确的sha1代码。以前，我使用以下程序在android studio的右侧使用gradle菜单找到了这个键：首先点击gradle然后在app下，Tasks，android，我点击了loginReport：

然后sha1出现在gradle控制台中：

我的falut是这个代码是用于调试模式！我按照以下步骤为我的发布密钥库获取sha1版本，在google开发人员控制台中输入这个新sha1后，我的地图完全显示。要获得sha1版本，首先应该复制发布密钥库地址：去构建＆gt;＆gt; generateSigendApk并复制密钥库路径。

然后你应该复制android studio使用的jdk的路径。转到文件＆gt;＆gt; ProjectStructure，你可以看到你的jdk路径。复制此路径并在cmd中转到此文件夹。

然后cd yor jdk然后bin文件夹并复制以下行： keytool -list -v -keystore“你的主题密钥存储路径”-alias“KEY ALIAS” 现在输入并享受你的发布sha1代码：）
