错误：图片从 sd 卡上传到 facebook android sdk 中的相册

Question

在我的 facebook android 应用程序中，我需要将图像从 sd 卡上传到 facebook 中的特定相册。我可以创建一个与 sd 卡文件夹同名的相册。但是在创建专辑之后它会得到一个异常——android.os.NetworkOnMainThreadException。这是我的代码-

private void uploadImage() 
{
    String ExternalStorageDirectoryPath = Environment
              .getExternalStorageDirectory()
              .getAbsolutePath();

    String targetPath = ExternalStorageDirectoryPath + "/Friends/";


    File targetDirector = new File(targetPath);

    File[] files = targetDirector.listFiles();

    for (File file : files)
    {      
        Bitmap bmp = BitmapFactory.decodeFile(file.getAbsolutePath());
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
        final byte[] data = stream.toByteArray();

        facebook.authorize(MainActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener()         
        {                   
            @Override                   
            public void onComplete(Bundle values)
            {

                if(verify)
                {
                    myAlbumId = createAlbumName();
                    verify=false;
                }
                uploadImagesToAlbum(data, myAlbumId);

            }  

            @Override   
            public void onFacebookError(FacebookError error)
            {
                Toast.makeText(MainActivity.this, "FaceBook Error", Toast.LENGTH_LONG).show();
            }

            @Override                     
            public void onError(DialogError e) 
            {
                Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_LONG).show();
            }                      

            @Override                     
            public void onCancel() 
            {
                Toast.makeText(MainActivity.this, "Canceled", Toast.LENGTH_LONG).show();
            }          
        }); 
    }

}

private String createAlbumName()
{
    Bundle params = new Bundle();
    params.putString("name", "Friends");
    params.putString("message", "My Test Album Description Here");
    mAsyncRunner.request("me/albums", params, "POST", new SampleUploadListener(), null);
    String response = "";
    String albumId = "";
    try {
        response = facebook.request("https://graph.facebook.com/me/albums",params,"POST");
    } catch (FileNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (MalformedURLException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    try {
        albumId=Util.parseJson(response).getString("id");
    } catch (FacebookError e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return albumId;
}

private void uploadImagesToAlbum(byte[] byteArray, String albumId)
{
    if ( albumId == null ) {
        albumId = "me";
    }
    Bundle params = new Bundle();
    params.putByteArray("picture", byteArray);
    mAsyncRunner.request(albumId+"/photos", params, "POST", new SampleUploadListener(), null);


}

这是我的日志-

如何将图片上传到相册？谢谢

Answer 1

您能否发布您的日志，以便所有人都可以帮助您..

它的连接错误不是图片上传错误。

你不能直接连接把你所有的网络访问放在一个线程或处理程序或异步任务上。

Answer 2

当应用程序尝试在其主线程上执行网络操作时会引发此异常。 我使用新线程解决了这个问题

Thread thread = new Thread()
{
    @Override
    public void run() {
        try {
            //Your code goes here
            }                               
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
};

thread.start();
