Question

我正在尝试通过电子邮件中的电子邮件和短信发送照片图像，因此编写了插件，它充当了java本机代码的桥梁。问题是，当我点击html“未找到类别”警报时的分享按钮加速。即使在config.xml文件中正确声明了插件名称，我也收到此错误，请帮帮我..

这是它的java代码。

public class Share extends CordovaPlugin {

private FileOutputStream outStream; 
private File file;
Bitmap bm;
public static final String ACTION_POSITION = "ShareImage";
Context context;

public Share(Context context) {
    this.context = context;

}

@Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext)
        throws JSONException {

    if (ACTION_POSITION.equals(action)) {

        try {
            JSONObject arg_object = args.getJSONObject(0);
            Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);
            sendIntent.setType("image/jpg");
            String uri = "@drawable/"+arg_object.getString("image")+".jpg";
            int imageResource = context.getResources().getIdentifier(uri, null, context.getPackageName());
            bm = BitmapFactory.decodeResource( context.getResources(), imageResource);
            String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
            file = new File(extStorageDirectory+ "/Download/", "imageee.png");

                try {
                outStream = new FileOutputStream(file);
                bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
                outStream.flush();
                outStream.close();
                } catch (FileNotFoundException e) {
                    System.out.println(" praise god........");
                e.printStackTrace();
                } catch (IOException e) {
                e.printStackTrace();
                }
            sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
            sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, arg_object.getString("image"));
            this.cordova.getActivity().startActivity(sendIntent);
            } catch (Exception e) {
                System.err.println("Exception: " + e.getMessage());
                callbackContext.error(e.getMessage());
            return false;
        }

    }
    return true;
    }
  }

Share.js插件

 var Share = function() {};

Share.prototype.show = function(success, fail, path) {
    return cordova.exec( function(args) {
        success(args);
    }, function(args) {
        fail(args);
    }, 'Share','', 'ShareImage', [{"image": path}]);
};
if(!window.plugins) {
    window.plugins = {};
}
if (!window.plugins.share) {
    window.plugins.share = new Share();
}

config.xml文件中的插件声明

<plugins>
    <plugin name="Share" value="com.picsswipe.Share"/>
</plugins>

html文件的onclick功能

instance.addEventHandler(PhotoSwipe.EventTypes.onToolbarTap, function(e){
                    if (e.toolbarAction === PhotoSwipe.Toolbar.ToolbarAction.none){
                            share();

  function share() {

请进行这些更改。在这里，我把你所有的js代码

    var Share = function() {};
Share.prototype.show = function(success, fail, path) {
    return PhoneGap.exec(function(args) {success(args);}, function(args) {fail(args);}, 'Share', 'ShareImage', [{"image": path}]);
};
    PhoneGap.addConstructor(function() {
        PhoneGap.addPlugin("share", new Share());
    });

instance.addEventHandler(PhotoSwipe.EventTypes.onToolbarTap, function (e) {
        if (e.toolbarAction === PhotoSwipe.Toolbar.ToolbarAction.none) {
            share();
        }
    });
    function share() {
        var imagename = ""; // Please give your image name here or page from share() function
        Share.prototype.show({path: "Image"},function (e) {alert(e);},function () {alert("Praise god :( ");},imagename);
    }

config.xml中

<feature name="Share">
   <param name="android-package" value="$Share.java file package name$"/>
</feature>

示例：

<feature name="Share">
    <param name="android-package" value="org.apache.cordova.plugin.Share"/>
</feature>

为了获得最佳方法，您可以为所有的phonegap插件创建包名package org.apache.cordova.plugin;。

我没有检查你的Share.java文件。我已经分享了我的工作短信插件代码HERE

请告诉我你有任何问题。

请删除以下代码

public Share(Context context) {
    this.context = context;
}

找不到类在phonegap android中的异常
