Question

我想在Android上使用地理位置。我在Apache Cordova中编写应用程序。地理位置不能同时在PC模拟器和手机上使用。

我试试http://cordova.apache.org/docs/en/2.4.0/cordova_geolocation_geolocation.md.html#geolocation.getCurrentPosition_full_example 和http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_geolocation

我的平台/ android / AndroidManifest.xml：

<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="1" android:versionName="0.0.1" android:windowSoftInputMode="adjustPan" package="net.example.test" xmlns:android="http://schemas.android.com/apk/res/android">
    <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
    <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="19" />
    <application android:debuggable="true" android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:name="Test" android:theme="@android:style/Theme.Black.NoTitleBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

WWW / config.xml中：

<?xml version='1.0' encoding='utf-8'?>
<widget id="net.example.test" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">

    <access origin="*" />
    <feature name="Geolocation">
        <param name="android-package" value="org.apache.cordova.GeoBroker" />
    </feature>
</widget>

我有cordova 3.3.1和这些插件：

$ cordova -v
3.3.1-0.4.2
$ cordova plugin ls
[ 'org.apache.cordova.console',
  'org.apache.cordova.device',
  'org.apache.cordova.dialogs',
  'org.apache.cordova.geolocation' ]
$

我在互联网上发现了很多问题（在stackoverflow上也是如此），但都没有用： - （

你有任何想法，我有错误吗？

更新：

现在我有了index.html：

<!DOCTYPE html>
<html><head>
    <script type="text/javascript" charset="utf-8" src="cordova.js"></script>
    <script type="text/javascript" charset="utf-8">

    // Wait for device API libraries to load
    document.addEventListener("deviceready", onDeviceReady, false);

    // device APIs are available
    function onDeviceReady() {
        console.log('in onDeviceReady()');
        navigator.geolocation.getCurrentPosition(onSuccess, onError);
    }

    // onSuccess Geolocation
    function onSuccess(position) {
        console.log('in onSuccess()');
        console.log(position.coords.latitude);
        console.log(position.coords.longitude);
        var element = document.getElementById('geolocation');
        element.innerHTML = 'Latitude: '           + position.coords.latitude              + '<br />' +
                            'Longitude: '          + position.coords.longitude             + '<br />' +
                            'Altitude: '           + position.coords.altitude              + '<br />' +
                            'Accuracy: '           + position.coords.accuracy              + '<br />' +
                            'Altitude Accuracy: '  + position.coords.altitudeAccuracy      + '<br />' +
                            'Heading: '            + position.coords.heading               + '<br />' +
                            'Speed: '              + position.coords.speed                 + '<br />' +
                            'Timestamp: '          + position.timestamp                    + '<br />';
    }

    // onError Callback receives a PositionError object
    function onError(error) {
        console.log('in onError()');
        console.log(error.code);
        console.log(error.message);
        alert('code: '    + error.code    + '\n' +
              'message: ' + error.message + '\n');
    }

    </script>
  </head><body><p id="geolocation">Finding geolocation...</p></body></html>

在Android模拟器中运行应用程序并运行logcat后，我看到：

$ telnet localhost 5554
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Android Console: type 'help' for a list of commands

$ adb logcat Cordova:* DroidGap:* CordovaLog:* *:S

你能帮帮我吗？

好吧，我在这个问题上挣扎了好几个小时（可能是几天），并想出了以下链接; https://issues.apache.org/jira/browse/CB-5977

我不确定它是否已经或将要被弃用。但无论如何，我的解决方案是＆＃34; rm org.apache.cordova.geolocation＆＃34;因为它根本不起作用。

然后我遇到了mozilla的以下链接; https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/Using_geolocation

并且我为了获得用户的位置而做的唯一事情如下：

<!DOCTYPE html>
<html>
<head>
<title>Device Properties Example</title>

</head>
<body>

<script src="http://192.168.43.15:8081/target/target-script-min.js#anonymous"></script>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">

 function geo_success(position) {
   alert("success" + " :  " + position.coords.latitude + ",  position.coords.longitude");
  //do_something(position.coords.latitude, position.coords.longitude);
}

function geo_error() {
alert("Sorry, no position available.");
}

var geo_options = {
enableHighAccuracy: true, 
maximumAge        : 30000, 
timeout           : 27000
}; 

var wpid = navigator.geolocation.getPosition(geo_success, geo_error, geo_options);
</script>
<p id="geolocation">Finding geolocationsss...</p>
</body>
</html>

注意：它确实适用于phonegapDevApp wirelessy但在真实设备上无效。这就是为什么我一直在以痛苦的方式查看和学习js文件应该在body里面而不是header，并从＆＃34; initialize＆＃34;中取代了我的navigator.geolocation.getPosition命令。以上＆＃34;初始化＆＃34; 。然后再次添加地理位置插件！

是的，最后，我的应用程序完美无缺。它显示了我的应用程序启动时固定当前位置的地图。

希望它也适合你！

之前，我在android上使用cordova-plugin-geolocation最新版本时遇到了问题。尝试以下版本

<plugin name="cordova-plugin-geolocation" spec="2.4.3" />
