android app에 로컬 호스트에 데이터를 게시하십시오.

Question

저는 android를 처음 접하고 내 Android app에서 localhost에 데이터를 게시하려고합니다. 오류를 표시하지 않고 항상 명령을 보냈지 만 파일을 쓰지 않고 있거나 데이터를 게시하지 않은 것일 수도 있습니다. 누구든지 문제를 발견 할 수 있습니까, 아니면 어떻게 해결할 수 있습니까?

Answer 1

당신은 로컬 호스트 시스템과 연결 10.0.2.2 IP 주소를 사용해야합니다.

HttpPost httppost = new HttpPost("http://localhost/text.php"); 

는

HttpPost httppost = new HttpPost("http://10.0.2.2/text.php"); 

Answer 2

1. 를 사용하여 IP 주소 대신 로컬 호스트이어야한다. 예 :

   HttpPost httppost = new HttpPost("http://192.168.0.10/mypage.php"); 
   

2. 이 AndroidManifest.xml 예에 인터넷 권한을 추가
