如何以编程方式在android中启用/禁用gps和移动数据?

I want my application to be able to enable/disable gps and mobile data programmatically as there are many apps like tasker, profile flow, lookout extra which can do this so I searched for it but not found any useful example I found the following code but they didn't work.

private void setMobileDataEnabled(Context context, boolean enabled) {
 final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
 final Class conmanClass = Class.forName(conman.getClass().getName());
 final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
 iConnectivityManagerField.setAccessible(true);
 final Object iConnectivityManager = iConnectivityManagerField.get(conman);
 final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
 final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
 setMobileDataEnabledMethod.setAccessible(true);

 setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
} 

private void turnGPSOn(){
 String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

 if(!provider.contains("gps")){ //if gps is disabled
    final Intent poke = new Intent();
    poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
    poke.setData(Uri.parse("3")); 
    sendBroadcast(poke);
 }
}

private void turnGPSOff(){
 String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

 if(provider.contains("gps")){ //if gps is enabled
    final Intent poke = new Intent();
    poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
    poke.setData(Uri.parse("3")); 
    sendBroadcast(poke);
 }
}
