파일을 열면 안드로이드 파일 선택에 실패 유지 나는 SD 카드 또는 구글에 드라이브 또는 안드로이드 파일 선택기를 사용하여 내부 메모리 중 하나를 저장 한 파일을 열고 읽을 노력하고

Question

...

파일을 성공적으로 선택한 후 다음 코드에 표시된대로 파일 경로를 가져 와서 읽을 때 파일이 존재하지 않음/파일이나 디렉터리가 없음 ...

내 코드 :

public class MainActivity extends AppCompatActivity { 

    private static final int CHOOSE_FILE_REQUEST_CODE = 1; 
    String[] ids; 
    TextView textView; 
    Button btnImport; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     textView = (TextView) findViewById(R.id.text_view); 


     btnImport = (Button) findViewById(R.id.btn_import); 

     btnImport.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
       intent.addCategory(Intent.CATEGORY_OPENABLE); 
       intent.setType("*/*"); 
       Intent i = Intent.createChooser(intent, "File"); 
       startActivityForResult(i, CHOOSE_FILE_REQUEST_CODE); 

      } 
     }); 



    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (data == null) { 
      return; 
     } 
     switch (requestCode) { 
      case 1: 
       if (resultCode == RESULT_OK) { 
        String path = data.getData().getPath(); 
        String url = data.getData().getPath(); 
        File file = new File(url); 
        Log.i("***", path); 
        // InputStream inputStream = getResources().openRawResource(R.raw.sample); 
        InputStream inputStream = null ; 
        BufferedReader bufferedReader = null; 

        try { 
         inputStream = new FileInputStream(file); 
         bufferedReader = new BufferedReader(new InputStreamReader(inputStream)); 
         String csvLine; 
         StringBuffer stringBuffer = new StringBuffer(); 

         while ((csvLine = bufferedReader.readLine()) != null) { 

          ids = csvLine.split(","); 

          for (int i = 0; i < ids.length; i++) { 
           if (i % 19 == 1) { 
            stringBuffer.append(ids[i]); 

            stringBuffer.append("\n"); 
            Log.i("***", stringBuffer.toString()); 

           } 
           textView.setText(stringBuffer.toString()); 
          } 
         } 


        } catch (FileNotFoundException e) { 
         e.printStackTrace(); 
        } catch (IOException e) { 
         e.printStackTrace(); 
        } 

       } 
     } 
    } 
}

열고 rigth 방법은 선택된 URI 컨텐츠 방식에 대한 InputStream에게 :

InputStream is = getContentResolver().openInputStream(data.getData());
