Translated from: Baidu. To better obtain the network connection status of the device, Android provides two classes to do this, namely connectivitymanager and networkinfo. Generally, we do not need to create them manually. Connectivitymanager object instance. We can obtain an instance through context object context. ConnectivityManager connManager = (ConnectivityManager)context. getSystemService(Context.

Android connection first, to determine the status of the network, you need to have the appropriate permissions, the following is the permission code (ANDROIDMANIFEST.XML): Copy Code code as follows: Then, detect if network state is available Copy Code code as follows: /** * Determine the
