Android Question Turn on/off data connection

[devmobile]

I saw below code in stackoverflow

private void setMobileDataEnabled(Context context, boolean enabled) throws ClassNotFoundException, NoSuchFieldException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {
    final ConnectivityManager conman = (ConnectivityManager)  context.getSystemService(Context.CONNECTIVITY_SERVICE);
    final Class conmanClass = Class.forName(conman.getClass().getName());
    final Field connectivityManagerField = conmanClass.getDeclaredField("mService");
    connectivityManagerField.setAccessible(true);
    final Object connectivityManager = connectivityManagerField.get(conman);
    final Class connectivityManagerClass =  Class.forName(connectivityManager.getClass().getName());
    final Method setMobileDataEnabledMethod = connectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
    setMobileDataEnabledMethod.setAccessible(true);

    setMobileDataEnabledMethod.invoke(connectivityManager, enabled);
}

How do i use it with java inline?

#If JAVA

private void setMobileDataEnabled(Context context, boolean enabled) throws ClassNotFoundException, NoSuchFieldException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {
 final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
 final Class conmanClass = Class.forName(conman.getClass().getName());
 final Field connectivityManagerField = conmanClass.getDeclaredField("mService");
 connectivityManagerField.setAccessible(true);
 final Object connectivityManager = connectivityManagerField.get(conman);
 final Class connectivityManagerClass = Class.forName(connectivityManager.getClass().getName());
 final Method setMobileDataEnabledMethod = connectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
 setMobileDataEnabledMethod.setAccessible(true);

 setMobileDataEnabledMethod.invoke(connectivityManager, enabled);}

#End If

And the rest is in the Tutorial here. It is easy

No tired
i use it and get error
src\b4a\example\main.java:408: error: cannot find symbol
public void setMobileDataEnabled(Context context, boolean enabled) throws ClassNotFoundException, NoSuchFieldException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {
^
symbol: class Context

were there any libraries that had to be imported into the Java version?

I used toggleLibrary but it is not working

The code further down in the same stactoverflow thread might be easier to use.

You will need the JavaObject library to be enabled
You will also have to import some Android classes after the #If Java line such as ConnectivityManager. If you put the Java code in the Main activity of your B4A project then you don't need to import Android class Context.

It is not possible to change the mobile data mode in newer versions of Android.
