Android L (5.x) Turn ON/OFF "Mobile Data" programmatically

I need to Turn ON/OFF Mobile data programmatically. Below code is not working for 5.x. Can you please help me. Thanks in advance.

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);    }

03-30 12:42:29.466: W/System.err(5966): java.lang.NoSuchMethodException: setMobileDataEnabled [boolean] 03-30 12:42:29.466: W/System.err(5966): at java.lang.Class.getMethod(Class.java:664) 03-30 12:42:29.466: W/System.err(5966): at java.lang.Class.getDeclaredMethod(Class.java:626)

Quick response, it is not possible to enable/disable mobile data by programming as it is possible with bluetooth.

Starting from version 23 of android, data protection begins to be highly valued and also the protection that an application activates or disables something on the phone, for this reason the permissions are implemented, taking this into account

Starting from this, google proposes that you encourage the user to do this action, giving him context and why he needs to have it activated.

Redirect the user to activate the data

Intent intent = new Intent(Settings.ACTION_DATA_USAGE_SETTINGS);
startActivity(intent);

Redirect the user to activate gps

Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);

Request enable Bluetooth

Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);

In Android L 5.xx the hidden API setMobileDataEnabled method is removed and it can no longer be used. You can verify this in android lolipop source code under /frameworks/base/core/java/android/net/ConnectivityManager.java.

If you still insist to perform it, you can use code snippet answered by Kushal but getDataEnabled is a system api, which normal user applications cant access. There is also one more system api available setDataEnabled under TelephonyManager. (/frameworks/base/telephony/java/android/telephony/TelephonyManager.java) 

/** @hide */
@SystemApi
public void setDataEnabled(boolean enable) {
 setDataEnabled(SubscriptionManager.getDefaultDataSubId(), enable);
}

It also needs the permission "android.permission.MODIFY_PHONE_STATE" which will work only on rooted devices.

It seems like the setMobileDataEnabled method no longer exists in ConnectivityManager and this functionality was moved to TelephonyManager with two methods getDataEnabled and setDataEnabled.

public void setMobileDataState(boolean mobileDataEnabled)
{
    try
    {
        TelephonyManager telephonyService = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

        Method setMobileDataEnabledMethod = telephonyService.getClass().getDeclaredMethod("setDataEnabled", boolean.class);

        if (null != setMobileDataEnabledMethod)
        {
            setMobileDataEnabledMethod.invoke(telephonyService, mobileDataEnabled);
        }
    }
    catch (Exception ex)
    {
        Log.e(TAG, "Error setting mobile data state", ex);
    }
}

public boolean getMobileDataState()
{
    try
    {
        TelephonyManager telephonyService = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

        Method getMobileDataEnabledMethod = telephonyService.getClass().getDeclaredMethod("getDataEnabled");

        if (null != getMobileDataEnabledMethod)
        {
            boolean mobileDataEnabled = (Boolean) getMobileDataEnabledMethod.invoke(telephonyService);

            return mobileDataEnabled;
        }
    }
    catch (Exception ex)
    {
        Log.e(TAG, "Error getting mobile data state", ex);
    }

    return false;
}

When executing the code you get a SecurityException stating that Neither user 10089 nor current process has android.permission.MODIFY_PHONE_STATE.

A permission MODIFY_PHONE_STATE should be added I got this from Answer Thank you Muzikant
