This article will explain in detail how to encapsulate a network detection class in Android. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.
Let's create a new class for networkUtils
Whether the network is available
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 accessibleProviders = locationManager.getProviders(true); return accessibleProviders != null && accessibleProviders.size() >0
}
Whether wifi is open or not
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)
}
Determine whether the current network is a wifi network
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
}
Determine whether the current network is a 3G network
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
}
Detection network
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
}
