Answer 1

Intent.flag_activity_clear_top 설정에서 내 모든 이전 활동을 삭제했다

Intent i = new Intent(_context, SignInActivity.class); 

    // Closing all the Activities 
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 

    // Add new Flag to start new Activity 
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

    // Staring Login Activity 
    _context.startActivity(i);
