Currently, this will be the case whenever the lock was * previously enabled. * * A setting is used to remember the current state of the lock (enabled / * disabled). An alternative route would be to use the package manager * to disable the boot receiver directly. While this will lead to a faster * boot when the lock is not enabled, there is a drawback: * PackageManager.setComponentEnabledSetting() is slooow. In fact, it will * slow down the system globally to the extend that even when run in a * separate thread, our toast message only displays with a delay, which * doesn't make a good impression on users. In other words, we're trading * a potentially cleaner solution and faster boot for perceived speed. * * Another advantage of the current solution might be that the setting * probably persists through installing an update. However, this is * untested, and a disabled component might persist just as well. */ public class BootReceiver extends BroadcastReceiver { static String PREFERENCES_FILE = "wifilock"; @Override public void onReceive(Context context, Intent intent) { Log.v(WifiLockService.LOG_TAG, "onReceive " + intent); if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) if (context.getSharedPreferences( PREFERENCES_FILE, Context.MODE_PRIVATE).getBoolean( "autostart", false)) WifiLockService.start(context, false); } static void enable(Context context, boolean enable) { Editor pref = context.getSharedPreferences( PREFERENCES_FILE, Context.MODE_PRIVATE).edit(); pref.putBoolean("autostart", enable); pref.commit(); } }
