DeviceManager

public class DeviceManager
extends Object

java.lang.Object
   ↳ com.google.android.things.device.DeviceManager


This class provides access to the device management service. Use this class to perform low-level device functions such as reboot and factory reset. Factory reset performs a wipe of all primary application internal storage and restores the device to its initial state following the most recent software update. Apps have the option of additionally erasing shared external storage.

 DeviceManager deviceManager = DeviceManager.getInstance();
 // Also erase shared external storage
 boolean wipeExternal = true;
 deviceManager.factoryReset(wipeExternal);

Setting Device Locale

Use the DeviceManager to control the default set of preferred locales available on the device.
 DeviceManager deviceManager = DeviceManager.getInstance();
 LocaleList newlist = new LocaleList();
 // ...add to the list...
 deviceManager.setSystemLocales(newlist);
