Telegram如何在Android應用程序中發送圖像和視頻？

Question

我正在開發一個消息聊天應用程序。我已經瀏覽了Telegram Android App的代碼，但沒有看到他們如何在聊天中發送圖片和視頻。如果您可以解釋該方法或爲此提供任何參考，這將非常有幫助。

TIA

您可以使用來自Android應用多內容發送任何類型的文件。你需要包括你的build.gradle

compile 'org.apache.httpcomponents:httpmime:4.3.6' 
compile 'org.apache.httpcomponents:httpcore:4.3.3' 


    private void sendImage(final String fileString, String fileMessageId) 

{ 
    Bitmap bitmap; 
    DataOutputStream dos = null; 


    String sResponse = null; 
    bitmap = BitmapFactory.decodeFile(fileString); 

    File sourceFile = new File(fileString); 


    String upLoadServerUri = WSConfig.UPLOAD_FILE_URL; 
    HttpClient httpClient = new DefaultHttpClient(); 

    HttpPost httpPost = new HttpPost(upLoadServerUri); 


    try { 


     MultipartEntity entity = new MultipartEntity(); 

     ByteArrayOutputStream bos = new ByteArrayOutputStream(); 

     entity.addPart("files", 
       new FileBody(sourceFile)); 


     httpPost.setEntity(entity); 
     HttpResponse response; 
     try { 
      response = httpClient.execute(httpPost); 

      BufferedReader reader = new BufferedReader(
        new InputStreamReader(
          response.getEntity().getContent(), "UTF-8")); 
      sResponse = reader.readLine(); 




     } catch (IOException e1) { 
      e1.printStackTrace(); 
     } 


    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
}
