Android Development How to quickly invoke system settings

Before, we typically call system settings (Time settings, network settings, and so on) in the following way:

1 New Intent (); 2 New ComponentName ("Com.android.settings",3         "com.android.settings.WirelessSettings"); 4 Intent.setcomponent (CN); 5 intent.setaction ("Android.intent.action.VIEW"); 6 startactivity (intent);

However, after testing, the use of the SDK4.0 version will throw an exception, then we can use the following way to invoke the System Setup interface:

  New Intent (Android.provider.Settings.ACTION_WIRELESS_SETTINGS);  StartActivity (Intent);

Using the fields below, you can open the appropriate system Setup interface in your software:

Android.provider.Settings.ACTION_SETTINGS //System settings

Android.provider.Settings.ACTION_APN_SETTINGS //access point settings

Android.provider.Settings.ACTION_SOUND_SETTINGS //Sound Settings

Android.provider.Settings.ACTION_WIRELESS_SETTINGS //Network Settings

Android.provider.Settings.ACTION_SECURITY_SETTINGS //Security Settings

Android.provider.Settings.ACTION_WIFI_SETTINGS //wifi Settings

Android.provider.Settings.ACTION_BLUETOOTH_SETTINGS //Bluetooth settings

Android.provider.Settings.ACTION_DATE_SETTINGS //Date and time settings

Android.provider.Settings.ACTION_BLUETOOTH_SETTINGS //Bluetooth settings

Here is only a list of commonly used fields, the other can be found in the official source code, is not very simple?!
