WEP/EAP WiFi configurationsAndroid에서 프로그래밍 방식으로 만들고 읽는 방법은 무엇입니까?
저는 다양한 포럼과 커뮤니티 전체에서이 질문에 대해 고군분투하는 많은 사람들을 보았습니다. 내가 똑같은 것을 이루고 싶을 때 나도 많은 어려움을 겪었 기 때문에 이것이 이해하기가 그렇게 간단하지 않다는 것을 알고 있습니다. 마침내 목표를 달성 할 수있었습니다. 모든 크레딧은 수많은 오픈 소스 프로젝트와 개발자에게 돌아갑니다.
저는이 지식을 모든 사람과 공유하고 싶습니다. SO 는 다음과 같이 권장 합니다. “당신이 위험에 처한 척하는 한 자신의 질문을 묻고 대답하는 것도 완벽하게 괜찮습니다. 질문의 형태로 표현하십시오.”

1 부 : 프로그래밍 방식으로 WEP WiFi 구성 만들기
이것은 매우 간단합니다. WifiConfiguration 은 인터페이스를 노출하여 동일하게 만듭니다. 다음은 샘플 코드입니다.
void saveWepConfig()
{
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
wc.SSID = "\"SSID_NAME\""; //IMP! This should be in Quotes!!
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.DISABLED;
wc.priority = 40;
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
wc.wepKeys[0] = "\"aaabbb1234\""; //This is the WEP Password
wc.wepTxKeyIndex = 0;
WifiManager wifiManag = (WifiManager) this.getSystemService(WIFI_SERVICE);
boolean res1 = wifiManag.setWifiEnabled(true);
int res = wifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean es = wifi.saveConfiguration();
Log.d("WifiPreference", "saveConfiguration returned " + es );
boolean b = wifi.enableNetwork(res, true);
Log.d("WifiPreference", "enableNetwork returned " + b );

Straighforward 다시 읽습니다. 다음은 샘플 코드입니다.

int i = item.size();

WifiConfiguration config = item.get(0);

}파트 3 : 프로그래밍 방식으로 EAP WiFi 구성 읽기
이제 이것은 까다 롭습니다. WifiDialog.java 에서 바닐라 Android UI를 통해 EAP WiFi 구성을 저장하는 코드를 찾을 수 있습니다. 충분히 쉽습니다. 응용 프로그램에서 동일한 코드를 사용할 수 있습니다. 이 작업을 시도하면 기호를 찾을 수 없다는 오류가 표시됩니다eap.phase,client_cert등. 조금 자세한 조사를 통해클래스내부의 EnterpriseField를 알 수 있으며 찾을 수없는 모든 기호는 유형입니다. 우리는 장애물에 부딪 혔습니다. EAP 구성을 읽고 저장하려면 이러한 필드가 필요하지만 프로그래밍 방식으로 액세스 할 수 없습니다! is privateWiFiConfigurationEnterpriseField
Java Reflection API구조를 위해
글쎄요 저는 Java 전문가가 아니므로 Reflection API에 대한 자세한 내용은 다루지 않을 것입니다. Google에서 자습서를 보거나 여기에서 자세한 정보를 얻을 수 있습니다 . 짧고 깔끔하게 유지하기 위해 Reflection API를 사용하면 컴파일 타임에 클래스, 메서드 등의 이름을 몰라도 런타임에 클래스, 인터페이스, 필드 및 메서드를 검사 할 수 있습니다. 리플렉션을 사용하여 새 개체를 인스턴스화하고 메서드를 호출하고 필드 값을 가져 오거나 설정할 수도 있습니다. 그리고 중요하게 리플렉션을 사용 하면 클래스 내부의 개인 데이터 멤버에 액세스하는 데 도움이 될 수 있습니다. 이게 필요하지 않나요? 🙂
이제 Reflection Api를 사용하여 EAP WiFi 구성을 읽는 방법을 보여주는 코드 예제를 확인해 보겠습니다. 보너스로 스 니펫은 구성을 파일에 기록하고 SD 카드에 저장합니다 …. 아주 매끄럽게 ..eh;) Reflection Api에 대한 약간의 개요를 살펴보면 아래 코드를 쉽게 파악할 수 있습니다.

Android는 JellyBean 4.3에 API를 추가했습니다. API 18에서 WIFI를 구성하려면이 옵션을 사용해야합니다.

}이것이 도움이되기를 바랍니다. @Android 학습자 adHocFrequency 및 SSID가 충돌을 일으키기 때문에 제거했지만 결과는 여전히 좋았습니다.

WEP 키는 마스킹되어 있으므로 언급 된 코드로는 읽을 수 없습니다.
Log.d("WifiPreference", "WEP KEY 0" + wepKeys[0]);
Log.d("WifiPreference", "WEP KEY 1" + wepKeys[1]);
Log.d("WifiPreference", "WEP KEY 2" + wepKeys[2]);
Log.d("WifiPreference", "WEP KEY 3" + wepKeys[3]);EAP 솔루션과 동일한 방식으로이 문제를 해결할 수있는 방법이 있습니까? 반성?
