Android Question SET APN internet settings from B4A app

[Philip Prins]

Hello

I would like to set the APN from B4A;

I found the following JAVA code;

 /*
     * Insert a new APN entry into the system APN table
     * Require an apn name, and the apn address. More can be added.
     * Return an id (_id) that is automatically generated for the new apn entry.
     */
    public int InsertAPN(String name, String apn_addr)
    {
        int id = -1;
        ContentResolver resolver = context.getContentResolver();
        ContentValues values = new ContentValues();
        values.put("name", name);
        values.put("apn", apn_addr);
       
        /*
         * The following three field values are for testing in Android emulator only
         * The APN setting page UI will ONLY display APNs whose 'numeric' filed is
         * TelephonyProperties.PROPERTY_SIM_OPERATOR_NUMERIC.
         * On Android emulator, this value is 310260, where 310 is mcc, and 260 mnc.
         * With these field values, the newly added apn will appear in system UI.
         */
        values.put("mcc", "310");
        values.put("mnc", "260");
        values.put("numeric", "310260");
       
        Cursor c = null;
        try
        {
            Uri newRow = resolver.insert(APN_TABLE_URI, values);
            if(newRow != null)
            {
                c = resolver.query(newRow, null, null, null, null);
                Log.d(TAG, "Newly added APN:");
                printAllData(c); //Print the entire result set
               
                // Obtain the apn id
                int idindex = c.getColumnIndex("_id");
                c.moveToFirst();
                id = c.getShort(idindex);
                Log.d(TAG, "New ID: " + id + ": Inserting new APN succeeded!");
            }
        }
        catch(SQLException e)
        {
            Log.d(TAG, e.getMessage());
        }

        if(c !=null )
            c.close();
        return id;
    }

 Set an APN to be the default
   /*
     * Set an apn to be the default apn for web traffic
     * Require an input of the apn id to be set
     */
    public boolean SetDefaultAPN(int id)
    {
        boolean res = false;
        ContentResolver resolver = context.getContentResolver();
        ContentValues values = new ContentValues();
       
        //See /etc/apns-conf.xml. The TelephonyProvider uses this file to provide
        //content://telephony/carriers/preferapn URI mapping
        values.put("apn_id", id);
        try
        {
            resolver.update(PREFERRED_APN_URI, values, null, null);
            Cursor c = resolver.query(
                    PREFERRED_APN_URI,
                    new String[]{"name","apn"},
                    "_id="+id,
                    null,
                    null);
            if(c != null)
            {
                res = true;
                c.close();
            }
        }
        catch (SQLException e)
        {
            Log.d(TAG, e.getMessage());
        }
         return res;
    }

How can i implement this in B4A?

Check ContentResolver library.
