Question

好的，所以我通过创建批处理文件获得了SHA1指纹。之后，我转到“服务”页面并启用了Google Maps API v2和v3。我还进入了“API Access”页面并使用SHA1; PACKAGENAME创建了一个新的Android Key。在此之后，我转到我的项目文件夹并添加了以下代码：

<permission
    android:name            = "com.example.test.permission.MAPS_RECEIVE"
    android:protectionLevel = "signature" 
/>

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

<uses-permission android:name="com.example.test.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

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

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

我还创建了一个XML文件并粘贴了以下代码：

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.maps.MapView
    xmlns:android           = "http://schemas.android.com/apk/res/android"
    android:id              = "@+id/mapview_MV"
    android:layout_width    = "fill_parent"
    android:layout_height   = "fill_parent"
    android:clickable       = "true"
    android:apiKey          = "APIKEY"
/>

在我的HTC One X +上编译和运行项目后，我只看到一堆灰色瓷砖。我还尝试在代码中使用MapView，如下所示：

/********************************************************************
* ONCREATE                                                          *
********************************************************************/
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView( R.layout.general_layout );

    MapView mapView = new MapView( GamePage.this, "APIKEY" );
    MapController mc = mapView.getController();
    String coordinates[] = {"1.352566007", "103.78921587"};
    double lat = Double.parseDouble(coordinates[0]);
    double lng = Double.parseDouble(coordinates[1]);

    GeoPoint p = new GeoPoint( (int) (lat * 1E6), (int) (lng * 1E6) );

    mc.animateTo(p);
    mc.setZoom(17); 

    FrameLayout fl = ( FrameLayout ) findViewById(R.id.general_frameHolder_FL);
    fl.addView(mapView);
}

我看到以下错误：

Couldn't get connection factory client

谁能告诉我，我到底做错了什么！？

Answer 1

当我们在MapView或Fragment中实施Activity时，必须实施其生命周期方法docs

把 mMapView.onCreate（savedInstanceState）;

在onCreateView()或onCreate()

内

 @Override
public void onResume() {
    super.onResume();
    mMapView.onResume();
}

@Override
public void onDestroy() {
    super.onDestroy();
    mMapView.onDestroy();
}

@Override
public void onPause() {
    super.onPause();
    mMapView.onPause();
}

尝试启用Google地图Android API v2 enter image description here

Meta键必须低于Application Tag

<permission
    android:name            = "com.example.test.permission.MAPS_RECEIVE"
    android:protectionLevel = "signature" 
/>

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

<uses-permission android:name="com.example.test.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

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

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <!-- key v2 -->
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="Bla Bla" />

    <uses-library
        android:name="com.google.android.maps"
        android:required="false" />
    <activity
        android:name="com.example.test.MainActivity"
        android:label="@string/st_google_activity_main" >
    </activity>
</application>

如果您使用MapView，则必须转发所有Activity life cycle methods。

XML布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
        <fragment
            android:id="@+id/map"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            class="com.google.android.gms.maps.SupportMapFragment" />
</LinearLayout>

类

public class MainActivity extends android.support.v4.app.FragmentActivity implements OnMapClickListener , OnMapLongClickListener , OnCameraChangeListener {
    private GoogleMap                   mMap;
    @Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_googlev2);
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
        mMap.setOnMapClickListener(this);
        mMap.setOnMapLongClickListener(this);
        mMap.setOnCameraChangeListener(this);
    }
}

Answer 3

在我看来api-key问题.. 试着以这种方式给予

android:apiKey="0BYX7MFyg8lWRKFxzwG-D93VMxZP6wH5eObwEtw"

检查日志..您是否从Google Map Lib收到任何错误日志？

为什么MapView显示灰色瓷砖而不是地图？
