Android封装网络检测的相关类

当我们手机的APP在用到网络时一般会先检测手机是不是能上网,或是上网是用的wifi还是手机流量,于是就把相关的网络检测信息封装到一个类里,直接调用方法即可实现了.

我们新建一个networkUtils的类

网络是否可用

public static boolean isNetworkAvailable(Context context) { ConnectivityManager connectivity = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); if (connectivity == null) { } else { NetworkInfo[] info = connectivity.getAllNetworkInfo(); if (info != null) { for (int i = 0; i < info.length; i++) { if (info[i].getState() == NetworkInfo.State.CONNECTED) { return true; } } } } return false; }

Gps是否打开

public static boolean isGpsEnabled(Context context) { LocationManager locationManager = ((LocationManager) context .getSystemService(Context.LOCATION_SERVICE)); List<String> accessibleProviders = locationManager.getProviders(true); return accessibleProviders != null && accessibleProviders.size() > 0; }

wifi是否打开

public static boolean isWifiEnabled(Context context) { ConnectivityManager mgrConn = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); TelephonyManager mgrTel = (TelephonyManager) context .getSystemService(Context.TELEPHONY_SERVICE); return ((mgrConn.getActiveNetworkInfo() != null && mgrConn .getActiveNetworkInfo().getState() == NetworkInfo.State.CONNECTED) || mgrTel .getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS); }

判断当前网络是否是wifi网络

public static boolean isWifi(Context context) { ConnectivityManager connectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo(); if (activeNetInfo != null && activeNetInfo.getType() == ConnectivityManager.TYPE_WIFI) { return true; } return false; }

判断当前网络是否是3G网络

public static boolean isMonet(Context context) { ConnectivityManager connectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo(); if (activeNetInfo != null && activeNetInfo.getType() == ConnectivityManager.TYPE_MOBILE) { return true; } return false; }

检测网络

public static boolean checkNet(Context context) { try { ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); if (connectivity != null) { NetworkInfo info = connectivity.getActiveNetworkInfo(); if (info != null && info.isConnected()) { if (info.getState() == NetworkInfo.State.CONNECTED) { return true; } } } } catch (Exception e) { return false; } return false; }
