Working on a Android network utility Know Your Android Network
I know that we can easily handle the changes in network state by creating our own Broadcast Receiver and check whether n/w switched from WiFi to Mobile data,
But is there a way to get notification when "Mobile Data" switches from one network type to the other. Basically I need to know when "mobile data" connection jumps from one network type to the other, Below can be the various network types:
NETWORK_TYPE_1xRTT
NETWORK_TYPE_CDMA
NETWORK_TYPE_EDGE
NETWORK_TYPE_EVDO_0
NETWORK_TYPE_EVDO_A
NETWORK_TYPE_GPRS
NETWORK_TYPE_HSDPA
NETWORK_TYPE_HSPA
NETWORK_TYPE_HSUPA
NETWORK_TYPE_UMTS
NETWORK_TYPE_EHRPD
NETWORK_TYPE_EVDO_B
NETWORK_TYPE_HSPAP
NETWORK_TYPE_IDEN
NETWORK_TYPE_LTE
For example, can i get a notification if a mobile data switches from EDGE to LTE.
Thanks!

Here are the Broadcast Intent Actions you can put in your IntentFilter:
android.net.conn.BACKGROUND_DATA_SETTING_CHANGED
android.net.conn.CONNECTIVITY_CHANGE
android.net.nsd.STATE_CHANGED
android.net.wifi.NETWORK_IDS_CHANGED
android.net.wifi.RSSI_CHANGED
android.net.wifi.SCAN_RESULTS
android.net.wifi.STATE_CHANGE
android.net.wifi.WIFI_STATE_CHANGED
android.net.wifi.p2p.CONNECTION_STATE_CHANGE
android.net.wifi.p2p.DISCOVERY_STATE_CHANGE
android.net.wifi.p2p.PEERS_CHANGED
android.net.wifi.p2p.STATE_CHANGED
android.net.wifi.p2p.THIS_DEVICE_CHANGED
android.net.wifi.supplicant.CONNECTION_CHANGE
android.net.wifi.supplicant.STATE_CHANGE
You can use these to trigger your BroadcastReceiver and from there you can get a reference to the TelephonyManager and check the network type using getNetworkType().
