无法在phonegap中显示联系人数据图像

Question

我试图使用下面的代码来获取联系人的个人资料相片即化身联系人数据PhoneGap的android ,但我得到回报以下网址,我不知道我应该如何表现它的img标签.

码

  var defaultImagePath ='../resources/images/default_usr.png'

 var img = contacts[i].photos  != null ? 
     contacts[i].photos[0].value : defaultImagePath;

返回的网址是

内容://com.android.contacts/contacts/739/photo

现在,当我最终在一个列表中,我试图显示它使用

<img src="content://com.android.contacts/contacts/739/photo"/>

但它没有显示任何东西？那么如何显示联系人图片？

我有最新PhoneGap版本

我用过

window.resolveLocalFileSystemURI(contacts [i] .photos [0] .value,this.onResolveSuccess,this.fail);

但我得到以下运行时错误

JNI ERROR (app bug): attempt to use stale local reference in phonegap

即使我在android中指定了以下权限

<uses-permission android:name="android.permission.VIBRATE" />
<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-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.BROADCAST_STICKY" />

UPDATE

loadContacts:function(){



    var arr = [];

    var filter = ["displayName", "name", "phoneNumbers","emails","addresses","photos"];
    var options = new ContactFindOptions();
    options.filter=""; 
    options.multiple=true;    

    navigator.contacts.find(filter,
              function(contacts) {

                for (var i = 0; i < contacts.length; i++) {
                  if (contacts[i].photos) {


                     for (var j = 0; j < contacts[i].photos.length; j++) {



                                returnValidPhoto(contacts[i].photos[j], function(answer) {

                                        console.log(answer);

                                        if(contacts[i].photos[j]!=null);
                                         contacts[i].photos[j].value=answer;


                                    });




                                 var contactData = new ContactData("Name" ,
                                                    "09090909",
                                                     contacts[i].photos[j].value);

                                arr.push(contactData);




                  }
                }

            }
            Ext.getStore('ContactStore').setData(arr);

               // document.getElementById("contactdata").innerHTML = data; 
            }, function(err) {
                alert(err);
              },options);



    }

这是图像功能

 function returnValidPhoto(url,callback){

    console.log("IMAGE CALLED");
    var img = new Image();
    img.onload = function() {
    //Image is ok

        console.log("IMAGE OK");

        callback(url.value);
    };
    img.onerror = function(err) {
        //Returning a default image for users without photo 

                console.log("IMAGE FAILED");

        url.value = "/resources/images/default_usr.png";
        callback("/resources/images/default_usr.png");
    }
    img.src = url.value;
};

Please try this.

     function onDeviceReady() {
            window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
            window.resolveLocalFileSystemURI("content://com.android.contacts/contacts/739/photo", onResolveSuccess, fail);
        }

        function onFileSystemSuccess(fileSystem) {
            console.log(fileSystem.name);
        }

        function onResolveSuccess(fileEntry) {
            console.log(fileEntry.name);
        }

        function fail(evt) {
            console.log(evt.target.error.code);
        }
