Hello,  
I am trying to make an application that allows activating and deactivating the mobile connection to the Internet in order to change IP

I have found code but it doesn’t work right.

This line gives an error: setMobileDataEnabledMethod.invoke(telephonyService, true);//MISTAKE Exception

Does anyone know how I could fix it?

```auto
void setup() {
  fullScreen();
  noStroke();
  fill(0); text("...", width/10, height/10); setMobileDataState(false);delay(3000);
   try {
          Activity act = this.getActivity();
  
  Context context = act.getApplicationContext();
   
         TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);
         Method setMobileDataEnabledMethod = Objects.requireNonNull(telephonyService).getClass().getDeclaredMethod("setDataEnabled", boolean.class);
         setMobileDataEnabledMethod.invoke(telephonyService, true);
      } catch (Exception ex) {
        text("Exception",222,22); /*Log.e("MainActivity", "Error setting mobile data state", ex);*/
      }delay(8000);
}

void draw() {
  background(204);
  
    if (isOnline()) {
      setMobileDataState(false);
      rect(0, 0, width/2, height);delay(5000);
     fill(150,1,1); text("OK-1",22,22); fill(0); 
       try {
          Activity act = this.getActivity();
  
  Context context = act.getApplicationContext();
   
         TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
         Method setMobileDataEnabledMethod = Objects.requireNonNull(telephonyService).getClass().getDeclaredMethod("setDataEnabled", boolean.class);
         setMobileDataEnabledMethod.invoke(telephonyService, false);
      } catch (Exception ex) {
        fill(150,1,1); text("Exception",222,22);fill(0); /*Log.e("MainActivity", "Error setting mobile data state", ex);*/
      }
      
      
      // Left
    } else {
   fill(0); rect(width/2, 0, width/2, height); // Right
    fill(150,1,1); text("1",22,82); setMobileDataState(true); text("OK-2",22,22); try {
          text("2",38,82); Activity act = this.getActivity();
  text("3",52,82); 
  Context context = act.getApplicationContext();
   text("4",72,82); 
         TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);
         text("5",92,82); 
         Method setMobileDataEnabledMethod = Objects.requireNonNull(telephonyService).getClass().getDeclaredMethod("setDataEnabled", boolean.class);
         text("6",122,82); 
         setMobileDataEnabledMethod.invoke(telephonyService, true);//MISTAKE Exception 
         
        
          text("7",152,82); 
      } catch (Exception ex) {
        fill(150,1,1); text("ERROR",222,22);fill(0); /*Log.e("MainActivity", "Error setting mobile data state", ex);*/
      }delay(5000);
      fill(0); 
    }

Hi. Just to better understand; can you give an example when this is needed?  
Further I don’t see that you gave the MODIFY\_PHONE\_STATE permission.  
Another thing with this “workaround” is that it will only work on rooted phones.

What you can do legally is open your network settings menu programmatically, like:

```auto
import android.content.Intent;

void setup() {
  fullScreen();
  orientation (PORTRAIT);
  background (0, 0, 150);
  textSize (60);
  textAlign (CENTER);
  text ("Click to open network settings menu.", width/2, height/2);
}

void draw () {
}

void mousePressed () {
  Intent intent = new Intent(Intent.ACTION_MAIN);
  intent.setClassName("com.android.phone", "com.android.phone.NetworkSetting");
  startActivity(intent);
}

```

Hi Noel,

Thanks You

I am making an application that allows detecting the texts copied on the network, however it can barely work 1 minute before the ip is blocked and it does not allow any more queries, so I want to automatically connect and disconnect to get a new IP.

Would that code work with root? Does the exception jump for this?  
If you confirm it, I will try to rotate an old phone to see if it works

A greatings and thanks so much

Do you mean something like Pigeon app, that copies text to the clipboard and then transmit to other devices? That can be done with oscP5.  
Who detects and blocks the IP? Can’t you use VPN?

Not, something like: [https://www.copyscape.com/](https://www.copyscape.com/)  
I need 20-30 querry for check a page  
Google, Bing … allow a few queries before blocking with catpcha for 1 hour. I am not sure that VPN can solved it.
