如何从绘制文件夹上传图像与图形API向Facebook？ [英] How to post image from drawable folder to facebook with graph api?

问题描述

我想用自己的图形API张贴到Facebook的图像。但我的形象是在绘制文件夹中。到目前为止：

I'd like to post an image to facebook by using their graph api. But my image is in drawable folder. So far:

public static void postToFacebook() {

    Bundle params = new Bundle();

    // shared with this
    params.putString("caption", activityContext.getString(R.string.app_name));
    // description of the program
    params.putString("description", "bla bla bla bla bla bla"); 
    // header of the description
    params.putString("name", "train");
    // callback url
    params.putString("link","http://www.google.com.tr");
    // put a personal message
    params.putString("message", "my message");
    // to put a photo
    params.putByteArray("picture", getImageAsData());

    try {
        String response = FacebookUtility.mFacebook.request("/me/feed",
                params, "POST");
        if (response == null || response.equals("")
                || response.equals("false"))
            Toast.makeText(activityContext, "Error.",
                    Toast.LENGTH_SHORT).show();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

public static byte[] getImageAsData() {

Drawable d = activityContext.getResources().getDrawable(R.drawable.icon);
Bitmap bitmap = ((BitmapDrawable) d).getBitmap();
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
    byte[] bitmapdata = stream.toByteArray();
    return bitmapdata;
}

但是，这是不工作...这不是我发帖的图标，但它会从网站获得谷歌图标。我尝试注释掉的链接部分，但这次没有发送任何东西，但消息。

But this is not working... It's not posting my icon, but it gets google icon from site. I try to comment out link part, but this time it didn't send anything but message.

我也试图得到位图：

Bitmap bitmap = BitmapFactory.decodeResource(activityContext.getResources(), R.drawable.icon);

但是，这也没有发挥出来。

But this also didn't work out.

我见过的：

Bitmap bi = BitmapFactory.decodeFile(pathonsdcard);

但我不能用这个方法来获取位图，因为我没有pathonsdcard？

But i couldn't use this method to get bitmap, because i have no pathonsdcard?

任何建议？
所以，我怎么可以发布它位于RES /文件夹的绘制形象？
先谢谢了。

Any suggestion? So how can i post image which is located in res/drawable folder ? Thanks in advance.

推荐答案

这是上传从绘制照片的正确方法。需要注意的是你唯一需要的参数是照片和标题。

This is the correct way to upload a photo from a drawable. Note that the only parameters you need is "photo" and "caption".

Bundle params = new Bundle();
params.putByteArray("photo", getImageAsData());
params.putString("caption", "Test caption lololol");
mAsyncRunner.request("me/photos", params, "POST", new PhotoUploadListener(), null);
