android - 未定义 Phonegap Android LocalFileSystem

Question

我在 phonegap 应用程序中出于存储目的访问 Android 文件系统时遇到问题。我搜索并找到了很多不适合我的情况的解决方案!

我知道 deviceready 被发射和检查的必要性，它被发射了。所以 phonegap.js 已完美加载!

我想我请求了文件权限并且在我的 list 和配置文件中有功能。他们在这里:

配置文件:

    <feature name="http://api.phonegap.com/1.0/device" />
    <feature name="http://api.phonegap.com/1.0/battery"/>

    <access origin="*" />
    <content src="index.html" />
</widget>

AndroidManifest.xml:

        </activity>
    </application>
    <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="18" />
</manifest>

这是我的代码的错误抛出部分:

$(document).ready(function () {
    document.addEventListener("deviceready", onDeviceReady, false);
});
function onDeviceReady() {
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) { //throws the 'Uncaught ReferenceError: LocalFileSystem is not defined' error
        fileSystem = fileSystem;
    }, function (evt) {
        alert(evt.target.error.code);
    });
}

但由于我不知道的原因，我得到了错误!请给我你的想法。非常感谢。

PS:我用的是phonegap 3.0!

您是否使用 phonegap cli 来构建您的项目？那么您可能错过了将文件插件添加到您的项目中。除了在 config.xml 和 AndroidManifiest.xml 中配置外，您还需要插件的代码。您可以将其添加到您的项目中:

$ phonegap plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-file.git 

查看文档中的页面顶部:http://docs.phonegap.com/en/3.0.0/cordova_file_file.md.html#LocalFileSystem

您还可以检查文件 android/assets/www/cordova_plugins.js 以查看是否实际定义了 window.LocalFileSystem。寻找这样的东西:

{
    "file": "plugins/org.apache.cordova.core.file/www/FileSystem.js",
    "id": "org.apache.cordova.core.file.FileSystem",
    "clobbers": [
        "window.FileSystem"
    ]
},
