for some reason SharedPreferences doesn't save the values, the code is in a service...

 Thread thread = new Thread() 
 public void run() 
 SharedPreferences sharedPref = getBaseContext().getSharedPreferences(getString(R.string.not_local_sp), MODE_PRIVATE);
 long lastExecuted = sharedPref.getLong(getString(R.string.timeDone), 0L);
 int scanInterval = 500 * 60 * 60;

 while (true) 
 if (System.currentTimeMillis() - lastExecuted >= scanInterval && contextCreator == null) 
 Log.d(TAG, "inside while loop");
 Log.d(TAG, String.valueOf(System.currentTimeMillis() - lastExecuted));
 Log.d(TAG, String.valueOf(lastExecuted));
 Log.d(TAG, String.valueOf(scanInterval));
 contextCreator = new ProtectionContextCreator();
 feature = AppScanFactory.createAppScan(getBaseContext());
 feature.add(new BoostFeature(getBaseContext(), new StubScanStore()));
 contextCreator.create(getBaseContext(), feature.getType(), NotificationService.this);

 /*Shared pref*/

 SharedPreferences.Editor editor = sharedPref.edit();
 editor.putLong(getString(R.string.timeDone), System.currentTimeMillis());
 editor.commit();
 

 try 
 Thread.sleep(1000);
 catch (InterruptedException e) 
 e.printStackTrace();
 
 
 
 ;
 thread.start();

the lastExecuted variable always get the default value, 0.

you have an infinite loop (while(true)) but you are reading the value outside it

this line

long lastExecuted = sharedPref.getLong(getString(R.string.timeDone), 0L)

should be inside the while loop (if you are using lastExecuted to check if the value was stored)
