适用于 Android 应用程序的 Java 代码中的实例化异常

我已经编写了从 HTML 格式的轮播滑块图像中获取当前页面的代码，并通过电子邮件和彩信在 Android 中使用 Java 进行 phonegap 项目共享。

这是我的 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, "image.png");
                try {
                outStream = new FileOutputStream(file);
                bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
                outStream.flush();
                outStream.close();
                } catch (FileNotFoundException e) {
                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;
}

}

一切顺利，但是当我单击"共享"按钮时，我收到异常，因为"找不到类"。问题出在上下文类中，尝试通过清理并删除Google中给出的gen文件，但没有任何效果。请帮我解决这个问题。
