问题描述

我正在开发中的PhoneGap（机器人）我的第一个应用程序。

I am developing my first application in phonegap (android).

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

        <script type="text/javascript" charset="utf-8" src="cordova-1.7.0.js"></script>
        <script type="text/javascript" charset="utf-8">
        alert('code: 1');
        // Wait for Cordova to load
        //
        document.addEventListener("deviceready", onDeviceReady, false);
        alert('code: 2');
        var watchID = null;
        alert('code: 3');
        // Cordova is ready
        //
        function onDeviceReady() {
            // Update every 3 seconds
            alert('code: 4');
            var options = { frequency: 3000 };
            watchID = navigator.geolocation.watchPosition(onSuccess, onError, options);
        }

        // onSuccess Geolocation
        //
        function onSuccess(position) {
            alert('code: 5');
            var element = document.getElementById('geolocation');
            element.innerHTML = 'Latitude: '  + position.coords.latitude      + '<br />' +
                                'Longitude: ' + position.coords.longitude     + '<br />' +
                                '<hr />'      + element.innerHTML;
        }

        // clear the watch that was started earlier
        // 
        function clearWatch() {
            alert('code: 6');
            if (watchID != null) {
                navigator.geolocation.clearWatch(watchID);
                watchID = null;
            }
        }

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

        </script>
      </head>
      <body>
        <p id="geolocation">Watching geolocation...</p>
        <button onclick="clearWatch();">Clear Watch</button>     
      </body>
    </html>

下面onDeviceReady方法是没有得到调用。请帮助我了解我错过了什么。

Here onDeviceReady method is not getting called. Kindly help me understand what i am missing.

我已经添加了这些权限

<uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

在manifest.xml文件。

in manifest.xml file.

推荐答案

按照这种方式，它应该工作。

Follow it this way and it should be working.

<!DOCTYPE html>
<html>
  <head>
    <title>Cordova Device Ready Example</title>

    <script type="text/javascript" charset="utf-8" src="cordova-1.7.0.js"></script>
    <script type="text/javascript" charset="utf-8">

    // Call onDeviceReady when Cordova is loaded.
    //
    // At this point, the document has loaded but cordova-1.7.0.js has not.
    // When Cordova is loaded and talking with the native device,
    // it will call the event `deviceready`.
    //
    function onLoad() {
        document.addEventListener("deviceready", onDeviceReady, false);
    }

    // Cordova is loaded and it is now safe to make calls Cordova methods
    //
    function onDeviceReady() {
        // Now safe to use the Cordova API
    }

    </script>
  </head>
  <body onload="onLoad()">
  </body>
</html>

另外，还要检查的Android例如文件夹在科尔多瓦1.7下载。

Also check the Android example folder in the Cordova 1.7 download.
