android에 여러 파일을 업로드하는 방법

Question

특정 폴더의 모든 파일을 업로드하고 싶습니다. 다음 코드에서 배열의 파일 목록을 저장했습니다.

String path = Environment.getExternalStorageDirectory().toString()+"/backup/";  
File f = new File(path);   
File file[] = f.listFiles(); 
int fileNum = file.length; 
String[] fileName = new String[fileNum]; 
for (int i=0; i < file.length; i++) {        
    fileName[i] = file[i].getName();         
} 

하나의 파일을 업로드하는 데 다음 코드가 있습니다. 배열 파일 이름에서 코드 나 나 루프를 할 경우 내가 어떤 부분을 제거

String path = Environment.getExternalStorageDirectory().toString()+"/backup/";  
    File f = new File(path);   
    File file[] = f.listFiles(); 
    for (int i=0; i < file.length; i++) {        
     // upload file here and when the fileUpload is complete the you save it to the array.. thats wat i think is best.. because you never know 
     //Thread or asynctask       
    } 

는 해당 배열에있는 모든 파일을 업로드 할 수 있도록. 주위에있는 나의 길 때문에 ... 당신은 그것을 추가하고 그것 주위에 당신의 길을 만들어 줄 수 있습니다. ..Lol 그것이 의미가 있기를 바란다.
