The Android ConnectivityManager is a system service provided by the Android operating system that manages network connections for an Android device. It provides APIs for applications to monitor and control the network connections of the device.
The ConnectivityManager can be used to determine the state of the network connection, such as whether the device is currently connected to a network, whether the connection is via Wi-Fi or cellular data, and whether the connection is metered or unmetered. It also provides APIs to request network connections, such as connecting to a specific Wi-Fi network or establishing a cellular data connection.
The ConnectivityManager also supports network callbacks, which allow applications to receive notifications when the network connection state changes. This can be useful for applications that need to perform certain tasks when the device connects or disconnects from a network.
Overall, the ConnectivityManager is an important component of the Android operating system that provides developers with powerful tools for managing network connections in their applications.
The Android ConnectivityManager is a system service in the Android operating system that enables apps to access network connectivity. It provides an interface for apps to check the state of network connectivity and to monitor changes in connectivity status. This service manages network connections for both Wi-Fi and mobile data.
The ConnectivityManager provides several methods to check the network connectivity status, such as getActiveNetworkInfo(), getNetworkInfo(int networkType), and isActiveNetworkMetered(). These methods return information about the current network, such as its type (e.g., Wi-Fi, mobile), whether it is connected, and whether it is metered (i.e., subject to data usage limits).
The ConnectivityManager also allows apps to register to receive notifications when the network connectivity state changes, using methods such as registerNetworkCallback(). This enables apps to respond to changes in network connectivity, for example by modifying their behavior or notifying the user.
In addition to managing network connectivity, the ConnectivityManager also provides APIs for managing Wi-Fi connections, such as enableNetwork(int netId, boolean disableOthers) and disconnect().
Overall, the Android ConnectivityManager is an essential component for developing network-connected apps on the Android platform, enabling developers to create apps that are responsive to changes in network connectivity and provide a seamless user experience.
