• Need guidance for my first Android application: how many activities should I use?

  - by jul

  Hi, I'm starting Android doing an application for searching restaurants, and some guidance would be welcome! On the first screen I'd like to have a search field with a submit button (I get the data from a web service), and below a list with the results of the search. When clicking on one of the items of the list it will show a screen with the restaurant details as well as a map showing its location. My questions are: Can I do everything in one single activity or should I do an activity for the search, one for the result list, one for the restaurant description, and another for the map? Would doing one single activity make the application more responsive? How can I use a list and a map within a normal activity (without ListActivity and MapActivity)? Any help, pointer, example application or sample code is very appreciated! Thank you Jul

• Issue with post data not received in a php page

  - by jul

  hi, I created a page in Wordpress (http://www.exam-vision.com/testmail) that sends POST data to itself in order to send an email. The code is shown below. While it seems that data are sent properly, it seems that they are not received since isset($_REQUEST['email']) is always false. Anybody could help? Thanks Jul <?php if (isset($_REQUEST['email'])) //if "email" is filled out, send email { //send email echo "isset email is true"; $email = $_REQUEST['email'] ; $subject = $_REQUEST['subject'] ; $message = $_REQUEST['message'] ; mail( "[email protected]", "Subject: $subject", $message, "From: $email" ); echo "Thank you for using our mail form"; } else //if "email" is not filled out, display the form { echo "<form method='post' action=''> Email: <input name='email' type='text' /><br /> Subject: <input name='subject' type='text' /><br /> Message:<br /> <textarea name='message' rows='15' cols='40'> </textarea><br /> <input type='submit' /> </form>"; } ?>

• NVidia with Optimus conflicting in Ubuntu 12.04

  - by Humannoise

  i have recently installed Ubuntu 12.04 in a Intel Ivy Bridge with integrated graphics and NVidia GPU with Optimus tech, however i cant manage it to work properly.

• Official end of support date for Internet Explorer 6 on Windows XP

  - by scunliffe

  If I read the docs on Windows Service Pack support policies, and the specific Internet Explorer lifecycle support page as well as the Wikipedia page I've deduced that: IE6 support ends/ended at: Windows 2000 Ended (date unknown) Windows XP SP0 (RTM) Ended Home: 30-Aug-2003 Pro: 30-Sep-2004 SP1 Ended Home: 11-Jul-2004 Pro: 11-Jul-2004 SP2 Home: 13-Jul-2010 Pro: 13-Jul-2010 SP3 (released: April 21, 2008) Home: ??? Pro: ??? What isn't clear is the Windows XP SP3 scenario. In "human" terms, when is the end of support for IE6 on Windows XP SP3? e.g. if there is never a Windows XP SP4... or heaven forbid, an SP4 is released. I realize this doesn't force people to upgrade etc. however I'm trying to get a "semi" official word on when IE6 moves into the "not supported" category. I'm not interested in philosophical answers e.g. "big enterprise won't upgrade but they will expect support into 2017" stuff... I just want the "clear answer" in terms of official Microsoft support.

• Postfix message ID originating process?

  - by Anders Braüner Nielsen

  Last night my postfix mail server(Debian Squeeze with dovecot, roundcube, opendkim and spamassassin enabled) started sending out spam from a single domain of mine like these: $cat mail.log|grep D6930B76EA9 Jul 31 23:50:09 myserver postfix/pickup[28675]: D6930B76EA9: uid=65534 from=<[email protected]> Jul 31 23:50:09 myserver postfix/cleanup[27889]: D6930B76EA9: message-id=<[email protected]> Jul 31 23:50:09 myserver postfix/qmgr[7018]: D6930B76EA9: from=<[email protected]>, size=957, nrcpt=1 (queue active) Jul 31 23:50:09 myserver postfix/error[7819]: D6930B76EA9: to=<[email protected]>, relay=none, delay=0.03, delays=0.02/0/0/0, dsn=4.4.2, status=deferred (delivery temporarily suspended: lost connection with mta5.am0.yahoodns.net[66.196.118.33] while sending RCPT TO) The domain in question did not have any accounts enabled but only a catchall alias set through postfixadmin - most emails were send from a specific address I use frequently but some were also sent from bogus addresses. None of the other virtual domains handled by postfix were affected. How can I find out what process was feeding postfix/sendmail or more info on where they originated? As far as I can tell php mail() wasn't used and I've run several open relay tests. I did a little tinkering(removed winbind from the server and ipv6 addresses from main.cf) after the attack and it seems to have subsided but I still have no idea how my server was suddenly sending out spam. Maybe I fixed it - maybe I didn't. Can anyone help figuring out how I was compromised? Anywhere else I should look? I've run Linux Malware Detect on recently changed files but nothing found.

• Help with listView in Android

  - by jul

  Hi, I'm just starting with Android and can't find how to display a list in my activity. I get some restaurant data from a web service and I'd like to show the results in a list.

How can I display, for instance, the list of the restaurant names in the ListView 'list' of my layout? thank you Jul public class Atable extends ListActivity { RestaurantList restaurantList; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //Here I set restaurantList //Now how can I display, for example, the list of the names of the restaurants } main.xml <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/search" /> <EditText android:id="@+id/search" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1"/> </LinearLayout> <LinearLayout android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="wrap_content"> <ListView android:id="@+id/android:list" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <TextView android:id="@+id/android:empty" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/noresults"/> </LinearLayout> </LinearLayout> Restaurant list class package org.digitalfarm.atable; import java.util.List; public class RestaurantList { private List<Restaurant> restaurants; public List<Restaurant> getRestaurants() { return restaurants; } public void setRestaurants(List<Restaurant> restaurants) { this.restaurants = restaurants; } } Restaurant class package org.digitalfarm.atable; public class Restaurant { private String name; private float latitude; private float longitude; public String getName() { return name; } public void setName(String name) { this.name = name; } public float getLatitude() { return latitude; } public void setLatitude(float latitude) { this.latitude = latitude; } public float getLongitude() { return longitude; } public void setLongitude(float longitude) { this.longitude = longitude; } }

• How can data not stored in a DB be accessed from any activity in Android?

  - by jul

  hi, I'm passing data to a ListView to display some restaurant names. Now when clicking on an item I'd like to start another activity to display more restaurant data. I'm not sure about how to do it. Shall I pass all the restaurant data in a bundle through the intent object? Or shall I just pass the restaurant id and get the data in the other activity? In that case, how can I access my restaurantList from the other activity? In any case, how can I get data from the restaurant I clicked on (the view only contains the name)? Any help, pointers welcome! Thanks Jul ListView lv= (ListView)findViewById(R.id.listview); lv.setAdapter( new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,restaurantList.getRestaurantNames())); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Intent i = new Intent(Atable.this, RestaurantEdit.class); Bundle b = new Bundle(); //b.putInt("id", ? ); startActivityForResult(i, ACTIVITY_EDIT); } }); RestaurantList.java package org.digitalfarm.atable; import java.util.ArrayList; import java.util.List; public class RestaurantList { private List<Restaurant> restaurants = new ArrayList<Restaurant>(); public List<Restaurant> getRestaurants() { return this.restaurants; } public void setRestaurants(List<Restaurant> restaurants) { this.restaurants = restaurants; } public List<String> getRestaurantNames() { List<String> restaurantNames = new ArrayList<String>(); for (int i=0; i<this.restaurants.size(); i++) { restaurantNames.add(this.restaurants.get(i).getName()); } return restaurantNames; } } Restaurant.java package org.digitalfarm.atable; public class Restaurant { private int id; private String name; private float latitude; private float longitude; public int getId() { return this.id; } public void setId(int id) { this.id = id; } public String getName() { return this.name; } public void setName(String name) { this.name = name; } public float getLatitude() { return this.latitude; } public void setLatitude(float latitude) { this.latitude = latitude; } public float getLongitude() { return this.longitude; } public void setLongitude(float longitude) { this.longitude = longitude; } }

  Out of the blue I can't start nautilus today.

• Laptop shuts down upon waking from suspend

  - by Bryan Head

  The computer enters suspend either by closing lid, choosing suspend from the top-right drop down, or hitting the power button and pressing suspend. It doesn't matter. I then attempt to wake the computer either by opening the lid (if it was closed) or hitting the power button. Again, doesn't matter. The computer will then immediately shutdown about 50% of the time. It seems to be more likely to shut down the longer it has been on suspend. I took a snapshot of /var/log/pm-suspend.log after a successfully resume and a shutdown. The only difference (outside of timestamps of course) was that a successful resume, after reporting the success of various suspend hooks, writes: Thu Jul 5 21:36:45 PDT 2012: performing suspend Thu Jul 5 21:37:10 PDT 2012: Awake. Thu Jul 5 21:37:10 PDT 2012: Running hooks for resume and then reports successful resume hooks. When it shuts down, the log ends at "performing suspend". I diffed the two files so I know this is the only difference. Thus, it looks like it's not even trying to wake up. Would love some ideas on this one. I've scoured the web but can't seem to find anyone else running into the same issue (it seems more common that the computer shuts down upon entering suspend, or only on hitting the power button to wake, and haven't seen any that are random like mine). I'll update with any requested information.

• 12c - flashforward, flashback or see it as of now...

  - by noreply(at)blogger.com (Thomas Kyte)

  Oracle 9i exposed flashback query to developers for the first time.  The ability to flashback query dates back to version 4 however (it just wasn't exposed).  Every time you run a query in Oracle it is in fact a flashback query - it is what multi-versioning is all about.However, there was never a flashforward query (well, ok, the workspace manager has this capability - but with lots of extra baggage).  We've never been able to ask a table "what will you look like tomorrow" - but now we do.The capability is called Temporal Validity.  If you have a table with data that is effective dated - has a "start date" and "end date" column in it - we can now query it using flashback query like syntax.  The twist is - the date we "flashback" to can be in the future.  It works by rewriting the query to transparently the necessary where clause and filter out the right rows for the right period of time - and since you can have records whose start date is in the future - you can query a table and see what it would look like at some future time.Here is a quick example, we'll start with a table:ops$tkyte%ORA12CR1> create table addresses  2  ( empno       number,  3    addr_data   varchar2(30),  4    start_date  date,  5    end_date    date,  6    period for valid(start_date,end_date)  7  )  8  /Table created.the new bit is on line 6 (it can be altered into an existing table - so any table  you have with a start/end date column will be a candidate).  The keyword is PERIOD, valid is an identifier I chose - it could have been foobar, valid just sounds nice in the query later.  You identify the columns in your table - or we can create them for you if they don't exist.  Then you just create some data:ops$tkyte%ORA12CR1> insert into addresses (empno, addr_data, start_date, end_date )  2  values ( 1234, '123 Main Street', trunc(sysdate-5), trunc(sysdate-2) );1 row created.ops$tkyte%ORA12CR1>ops$tkyte%ORA12CR1> insert into addresses (empno, addr_data, start_date, end_date )  2  values ( 1234, '456 Fleet Street', trunc(sysdate-1), trunc(sysdate+1) );1 row created.ops$tkyte%ORA12CR1>ops$tkyte%ORA12CR1> insert into addresses (empno, addr_data, start_date, end_date )  2  values ( 1234, '789 1st Ave', trunc(sysdate+2), null );1 row created.and you can either see all of the data:ops$tkyte%ORA12CR1> select * from addresses;     EMPNO ADDR_DATA                      START_DAT END_DATE---------- ------------------------------ --------- ---------      1234 123 Main Street                27-JUN-13 30-JUN-13      1234 456 Fleet Street               01-JUL-13 03-JUL-13      1234 789 1st Ave                    04-JUL-13or query "as of" some point in time - as  you can see in the predicate section - it is just doing a query rewrite to automate the "where" filters:ops$tkyte%ORA12CR1> select * from addresses as of period for valid sysdate-3;     EMPNO ADDR_DATA                      START_DAT END_DATE---------- ------------------------------ --------- ---------      1234 123 Main Street                27-JUN-13 30-JUN-13ops$tkyte%ORA12CR1> @planops$tkyte%ORA12CR1> select * from table(dbms_xplan.display_cursor);PLAN_TABLE_OUTPUT-------------------------------------------------------------------------------SQL_ID  cthtvvm0dxvva, child number 0-------------------------------------select * from addresses as of period for valid sysdate-3Plan hash value: 3184888728-------------------------------------------------------------------------------| Id  | Operation         | Name      | Rows  | Bytes | Cost (%CPU)| Time     |-------------------------------------------------------------------------------|   0 | SELECT STATEMENT  |           |       |       |     3 (100)|          ||*  1 |  TABLE ACCESS FULL| ADDRESSES |     1 |    48 |     3   (0)| 00:00:01 |-------------------------------------------------------------------------------Predicate Information (identified by operation id):---------------------------------------------------   1 -

• Getting an updated location in Android

  - by jul

  Hi, I'm using the code shown below to get an updated value for location every time a button is clicked. When my activity is resumed I get an update every second, so that when I call getLastKnownLocation I expect to have a location that have been updated in the last second. Is that the correct way to do that? I would expect the onLocationChanged event to be triggered every time I execute a 'geo fix' command (or max after 1s since I request update every 1s), but it's only triggered the first time. Why? Any help/suggestion welcome! Thanks package org.digitalfarm.atable; ... public class Atable extends Activity { private Button mSearchButton; private TextView mytext; private LocationManager locationManager; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mSearchButton = (Button)this.findViewById(R.id.button); mytext = (TextView) findViewById(R.id.dude); locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); final Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mSearchButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); } }); } //Start a location listener LocationListener onLocationChange=new LocationListener() { public void onLocationChanged(Location loc) { //sets and displays the lat/long when a location is provided String latlong = "Lat: " + loc.getLatitude() + " Long: " + loc.getLongitude(); mytext.setText(latlong); } public void onProviderDisabled(String provider) { // required for interface, not used } public void onProviderEnabled(String provider) { // required for interface, not used } public void onStatusChanged(String provider, int status, Bundle extras) { // required for interface, not used } }; //pauses listener while app is inactive @Override public void onPause() { super.onPause(); locationManager.removeUpdates(onLocationChange); } //reactivates listener when app is resumed @Override public void onResume() { super.onResume(); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,100.0f,onLocationChange); } }

  is there any way to create one animation with ObjectAnimator to change the background of a View with a crossfade animation? Something like ObjectAnimator.ofObject(<myView.background>, <crossfade or fade in -fade out>, <resources_1>, <resources_2>); I know I can do a fade out of one image, set a listener to detect the end of the animation, and fade in the other image. I'd just like to know if there's a more elegant way... Thanks
