How can I permanently disable mobile data connections in Android?
I know I can turn this on and off in the menu, but what I want is to permanently make it impossible.for anyone to turn this on, for example.by deleting a necessary file (similar to deleting IO80211Family.kext on a Mac).
At the same time, I want to retain the possibility to connect via WLAN.
Please provide an idiot level explanation.
"Please provide an idiot level explanation." I can not do this, because SO is not allowing it.
About solution to your problem,
Step-1 : Register receiver with android.net.conn.CONNECTIVITY_CHANGE action in manifest.
Step-2 : onReceive method of broadcastreceiver, check for the type of internet connection Data connection / WLAN.

But you can still register a listener for network changes.

When you get the onLost() event you can start a Wireless Setting Activity so the user can do it manually.
//As seen in the link above.
Intent intent = new Intent(Settings.ACTION_WIRELESS_SETTINGS);
startActivity(intent);
This will be a common occurrence so get use to it. For example you can createBond() for a Bluetooth device, but you can't removeBond() anymore. Thus you have to send the user to the Bluetooth setting activity for the user to
"forget" about the device.
I am trying to read the Preferred network type setting from the device. But nowhere android API's are available.
Use case:
Trying to read the Preferred network type and connected network type so that if the device has LTE enabled and the user is forcefully switched back to the lower network(3G,2G); then there should be a notification sent to the user.
I have checked the system setting code, But it's deprecated.
Settings.Secure.getString(getApplicationContext().getContentResolver(),
Settings.System.NETWORK_PREFERENCE);
Is there any alternate way to read the system secured settings(By reflection?).
And Also is it possible to write back the setting with the user permission?
Help is much appreciated.
I think the right code is:
Settings.Global.getString(context.getContentResolver(),Settings.Global.NETWORK_PREFERENCE)
I want to disable the wifi when not connect to any network. It will be running in the background and disabled anytime when wifi are enable and not used. How can I do that? Please give me some advice. I have to use Foreground or Service/ Broadcast Receiver.
You may be interested in Tasker. It can automate basically every setting in Android.
You can make a profile State> Variable Value> %WIFI=on Action: If "Wifi Info" %WIFII !contains "CONNECTION" then Net> Toggle Wifi> Off
You can also do this in Java with a bit more work. I can provide details on that if you request.
And also if you're lazy you can download neat little apps that take care of it for you: Auto Wifi Off
Hope that helps
How can I programmatically check that internet access in a android device is only over Wi-Fi and not over Packet Data connections like UMTS EDGE or GPRS ?
if you want your app to only use one particular type of data connection, you can form if/else logic and use check for mobile-network-access and wifi-access and give command accordingly
you can refer to mobile-network-access and wifi-access questions of stackoverflow for check on connection availability
I am building an app which requires an access point to be enabled throughout... how can i get an interrupt or notification whenever the access point gets disabled...?
Do you need a WIFI connection or any connection at all? This will trigger when wifi drops:
SUPPLICANT_CONNECTION_CHANGE_ACTION
