android - 如何从sdcard上传图片到facebook

Question

我已经使用 Facebook SDK 完成了文本共享。我坚持从 SD 卡上传图像。在将图像解析为 FB SDK 之前，首先我将图像转换为位图，然后我应该与 Facebook 共享。但是这个逻辑是行不通的。它从不从 SD 卡上传图像。谁能指导我如何从 SD 卡上传图像？提前致谢。

Bitmap bi = BitmapFactory.decodeStream(fis);
Bitmap bi =BitmapFactory.decodeFile(Environment.getExternalStorageDirectory() +"/Android/test.jpg", options);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);

Answer 1

尝试下面的代码并检查你的位图不应该为空..

Bundle bundle = new Bundle();
bundle.putString("message", "post image.." );

byte[] data = null;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
<<your bitmap>>.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();

bundle.putString(Facebook.TOKEN, facebook.getAccessToken());
bundle.putString("method", "photos.upload");
bundle.putByteArray("picture", data);
bundle.putString("message", "post image.." );

mAsyncRunner.request(null,bundle,"POST",new RequestListener() {
    @Override
    public void onMalformedURLException(MalformedURLException e, Object state) {
      Log.d("request RequestListener", "debug onMalformedURLException");
    }
    @Override
    public void onIOException(IOException e, Object state) {
  Log.d("request RequestListener", "debug onIOException");
    }
    @Override
    public void onFileNotFoundException(FileNotFoundException e, Object state) {
  Log.d("request RequestListener", "debug onFileNotFoundException");
    }
    @Override
    public void onFacebookError(FacebookError e, Object state) {
  Log.d("request RequestListener", "debug onFacebookError");
    }
    @Override
    public void onComplete(String response, Object state) {
   Log.d("request RequestListener", "debug onComplete");
    }
}, null);
