settings

Anyone who knows why this code ain't lowering the backlight of my application? Context context = this; Settings.System.putInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS, 255); Applications are no longer allowed to modify the global brightness.

The official API to set the brightness is with WindowManager.LayoutParams

I was wondering what the norm is for creating these settings. Say for example I would like one of the settings to be to change the name of the application name, or change a colour of the header. What I am looking for is for someone to explain the basic process/method - not necessarily specific code - although that would be great! For general application configuration that doesn't need to be stored in a database

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(
