Question

我开发了聊天应用程序。要在聊天中传输图像，我们首先将其上传到内容模块，然后将该ID共享给接收者。如果出现问题，我们会在messagelistner中调用getFile。但是，在该方法之外放置相同的代码可以正常工作请看下面的代码：

MyChatController.java

  private MessageListener messageListener = new MessageListener() {
    @Override
    public void processMessage(Chat chat, Message message) {
            System.out.println(String.format(">>> Message received (from=%s, to=%s): %s",from, to, message.getBody()));

        if (onMessageReceivedListener != null)
        {
            onMessageReceivedListener.onMessageReceived(message);
        }
     }
   };

此方法的实现在ChatActivity

中

ChatActivity.java


private ChatController.OnMessageReceivedListener onMessageReceivedListener = new ChatController.OnMessageReceivedListener()
 {

        public void onMessageReceived(final Message message)
        {
            final String from = message.getFrom().split("-")[0];
            final String messageString = message.getBody();
            Log.v("----msg from----","from ap "+ from+"-----"+friend.getId().toString());
            if(from.equalsIgnoreCase(friend.getId().toString()))
            {   

                if(messageString.startsWith(">>In thread");
                                    URL url = new URL(imageUrl);
                                    Log.v("---CONNECTION url---","In thread---"+url);
                                    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
                                    urlConnection.setRequestMethod("GET");
                                    urlConnection.connect();                
                                    String fileDir=null;
                                    File file=null;
                                    File ffile;
                                    if(fileType==SELECT_IMAGE)
                                    {
                                        fileDir=SDCardRoot+"/Globr/Images";
                                    }       
                                    ffile=new File(fileDir);
                                    if(!ffile.exists())
                                    {
                                        ffile.mkdirs();
                                    }           
                                    file = new File(fileDir,filename);
                                    Log.v("---folder file name---","image folder fil created---"+filename);
                                    if(!file.exists())
                                    {
                                        file.createNewFile();
                                    }


                                    FileOutputStream fileOutput = new FileOutputStream(file);

Answer 1

onMessageReceived 方法可能会调用非主线程或类似的东西

尝试在主线程上调用代码
