Answer 1

public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    // TODO Auto-generated method stub 
    super.onActivityResult(requestCode, resultCode, data); 

      if (requestCode == CAMERA_REQUEST && resultCode == getActivity().RESULT_OK)  { 
        File file = new File(mCapturedImagePath); 
        file.delet(); 
      } 
    } 

or u can use only this(as your condition) 
File file = new File(mCapturedImagePath); 
file.delet(); 

Answer 2

File file = new File(Environment.getExternalStorageDirectory()+"image_name"); //if your image is directly inside sdcard 
file.delete(); 

Answer 3

использование ниже кода может помочь вам.

File fdelete = new File(file_dj_path); 
    if (fdelete.exists()) { 
     if (fdelete.delete()) { 
      System.out.println("file Deleted :" + file_dj_path); 
     } else { 
      System.out.println("file not Deleted :" + file_dj_path); 
     } 
    } 

ниже код для обновления галереи после удаления изображения

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, 
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
