谷歌地图v2模块. Android应用程序未在地图视图中显示地图

我正在使用新的Google map v2模块在我的Android应用程序中显示地图.我正在做以下步骤.应用程序安装和工作正常.我面临的问题是视图中没有地图.

1)首先我已下载地图模块并放入下面的文件夹.

/Users/fkamani/Library/Application\ Support/Titanium/modules/android/

2)在tiapp.xml文件中添加map模块.

<module platform="android">ti.map</module>

3)在tiapp.xml中添加以下android清单

<android xmlns:android="http://schemas.android.com/apk/res/android">
        <manifest>
            <!-- Allows the API to download data from Google Map servers -->
            <uses-permission android:name="android.permission.INTERNET"/>
            <!-- Allows the API to cache data -->
            <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
            <!-- Use GPS for device location -->
            <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
            <!-- Use Wi-Fi or mobile connection for device location -->
            <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
            <!-- Allows the API to access Google web-based services -->
            <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
            <!-- Specify OpenGL ES 2.0 as a requirement -->
            <uses-feature android:glEsVersion="0x00020000" android:required="true"/>
            <!-- Replace com.domain.appid with your application ID -->
            <uses-permission android:name="com.mycompanyname.myprojectname.permission.MAPS_RECEIVE"/>
            <permission android:name="com.mycompanyname.myprojectname.permission.MAPS_RECEIVE"
                android:protectionLevel="signature"/>
            <application>
                <!-- Replace "PASTE YOUR GOOGLE MAPS API KEY HERE" with the Google API key you obtained -->
                <meta-data android:name="com.google.android.maps.v2.API_KEY"
                    android:value="My App key"/>
            </application>
        </manifest>
    </android>

4)改变Titamium sdk版本.

<sdk-version>3.0.2.GA</sdk-version>

5)从钛文档中复制下面的代码并放入app.js文件中

var MapModule = require('ti.map');
var win = Titanium.UI.createWindow();

var mountainView = MapModule.createAnnotation({
    latitude:37.390749,
    longitude:-122.081651,
    title:"Appcelerator Headquarters",
    subtitle:'Mountain View, CA',
    pincolor:MapModule.ANNOTATION_RED,
    myid:1 // Custom property to uniquely identify this annotation.
});

var mapview = MapModule.createView({
    mapType: MapModule.NORMAL_TYPE,
    region: {latitude:33.74511, longitude:-84.38993,
            latitudeDelta:0.01, longitudeDelta:0.01},
    animate:true,
    regionFit:true,
    userLocation:true,
    annotations:[mountainView]
});

win.add(mapview);
// Handle click events on any annotations on this map.
mapview.addEventListener('click', function(evt) {
    Ti.API.info("Annotation " + evt.title + " clicked, id: " + evt.annotation.myid);
});
win.open();

6)我创建了新的密钥库文件,并使用此密钥库文件创建分发构建.

7)为了创建谷歌地图API密钥,我在控制台中复制了SHA1证书指纹; com.mycompanyname.myprojectname.

应用程序已成功安装在我的Samsung S3设备中.当我运行应用程序时,它显示地图视图, – 缩放按钮.唯一的问题是地图视图中没有地图.

解决方法:

在移动设备上编译时检查Studio控制台,并查找：

[DEBUG] jarsigner -sigalg MD5withRSA -digestalg SHA1 -storepass ******* -keystore "YOUR_PATH_TO_KEYSTORE" -signedjar 

如果密钥库位于“… / mobilesdk / osx / 3.0.2.GA / android / dev_keystore”中,则需要使用dev_keystore的SHA1证书创建google maps API密钥.

这对我有用.
