Android KitKat set language for Bluetooth voice dial [General]

Android KitKat set language for Bluetooth voice dial

Android KitKat set language for Bluetooth voice dial

Hi, i'm having a problem with my new Nexus 5. Please note this is my first android device.

I cant figure out how to change the input language for dialing with a bluetooth headset which is pretty annoying since most of my contacts have french names. Everything else works fine with french voice commands on the phone except for the bluetooth voice dialer which always specifies English on the top right.

Can anyone tell me how to change this? I would prefer to keep the menus un english if possible, but I have even tried removing english and setting french everywhere and it didn't change the voice dialing option.

Thank you

Storage [General]

Storage

My phone is really struggling for storage so I deleted a bunch of videos and pictures worth about 150Mb. That did not make a difference at all for some reason. Anyways if I go to Settings --> Apps --> Here I see my download phone memory is almost full but my internal storage is almost empty with almost 2GB free. And is RAM has just gone to **** and is literally full. Can I remove everything for downloads if its now on my internal storage? And what can I do about the RAM? Thanks.

Text inflation in Chrome on Nexus 5 [General]

Text inflation in Chrome on Nexus 5

First post and a new Android convert here, so excuse me if I at any point come across as a bit daft. Anywho...

I picked up a Nexus 5 last week and noticed that Chrome inflates text in places it shouldn't. I seems to happen on sites like Reddit or other forum/comment driven sites, with lots of text in lots of frames and elements and such. The top of the pages are fine, but after a certain point down the page everything becomes inflated. Screen cap linked to so you can see what I mean.

I haven't had the chance to play around with my phone nearly enough to confirm, but it seems to be specific to Chrome... Firefox and Opera render pages perfectly. I've reformatted the phone, made sure the OS and all apps are up to date, closed out all other apps, etc etc, to no avail. I've tried searching for an answer online, both here and elsewhere, but I can't seem to find anything. I even called Google, but the rep was a bit clueless and kept insisting it must be some kind of connectivity issue.

Anyway, it's not a huge thing, but it's annoying me to no end that I can't figure it out. Help?

Adding a marker results in NullPointerException in Android [android help]

Adding a marker results in NullPointerException in Android

This is a part of my project. I am getting an arraylist of longitude and latitude from the previous class. Without the marker code, the app is working properly but when I add the marker code the app is terminating due to NullpointerException. Can anyone tell me why ?

    double s_latitude = latitude.get(0);
    double s_longitude=longitude.get(0);


    /* If I add this line the app is terminating.
      map.addMarker(new MarkerOptions()

What is the befitting protocol between mobile(iphone, android) and server PHP/MySQL? [android help]

What is the befitting protocol between mobile(iphone, android) and server PHP/MySQL?

How are you?
I am developing the School-Parents Message Systems.
Here is my initial system spec.
1. School teacher create a new message on PC(by website) or Mobile(by website or mobile app).
In this point of time, the teacher can set a parents list that should be received the message.
2. Each mobile device of the parents list display the message that the teacher already created.
3. The parents can reply to the teacher concerning the message on mobile.
4. The teacher also can reply to the parents concerning the message that was replied by parents on mobile(of course the teacher can reply on PC).
The messages can be communicated between teacher-parents, teacher-pupils, teacher-teacher, parents-parents, parents-pupils, pupils-pupils.

Here is my initial development spec.
I am guessing the number of clients include teacher, parents and pupils as 200,000+.
I need to develop for the iphone and android.
I am going to use the PHP/MySQL for the development of server side.
So, I am planning to implement the server side in the following way.
I.E. All of the messages are created to the MySQL DB.
In DB may be exist the config parameter field can specify the messages such as created_date, sender, receiver, deliver_date etc.
Then a mobile device check a new message in DB regularly and display the message.
If a clients reply to the message, then the message will be send to the server and is inserted in DB.

It is my small idea.
So, what is the my questions and problems?

How can the mobile device check a new message regularly?
Probably, you might advise to use the Push Notification service.
But, I cannot use any other service.

1. What is the protocol between mobile and server?
I am guessing to use HTTP.
So, JSON or XML might be offered the data to communicate between mobile app and server.

2. How can be executed the mobile app regularly?
I hope, whenever new message is registered in our system, that should be reflected into the mobile app immediatly, not pulling regularly.

If it is impossible, so the mobile check regularly e.g. 1min or 10min or 30min, then when use HTTP, here it is my cares.
Regularly the mobile can be access to server to check a new message.
Number of clients is larger than 200,000+.
So, server always must reponse about the request from 200,000+ clients regularly(e.g. 1min or 10min or 30min).
Is it clear architecture?
I am very trouble in the server performance point of view.

If you have a good idea and excellent architecture system, please teach me.

Thanks a lot for your time.

Kind regards

How can Google make it possible to use ActionBar in Google Shopper app, which only requires a min SDK of 8? [android help]

How can Google make it possible to use ActionBar in Google Shopper app, which only requires a min SDK of 8?

	I'm confused with this fact, and I think some feature must require getActionBar() and this function requires a min SDK of 11, but how can Google make those features possible? I wonder Google may use ActionBarSherlock, is this just the reason? But there is no mention of using it, but how can Google do this? Thanks for your answering. asked Jun 14 at 11:43

	Google is actually working on ActionBarCompat . It's basically a ActionBarSherlock from Google. I suppose they are testing this in some apps already since they said at Google I/O that it is in an advanced state of development. I think they will release this in the next few months. answered Jun 14 at 11:53

but how can Google make those features possible? They made their own action bar, presumably. I wonder Google may use ActionBarSherlock, is this just the reason? You are welcome to get a job with Google, attempt to join the Google Shopper team, and ask them. And have anyone ever use ActionBarSherlock on Android 2.2, plz tell me if it can make things just as well as ActionBar? ActionBarSherlock definitely supports Android 2.2. answered Jun 14 at 11:46

Listview not showing on orientation Change [android help]

Listview not showing on orientation Change

I have previously done a listview and the list is being displayed whether in landscape or portrait orientation. However, in my new app, when I decide to change orientation, whether landscape to portrait or vice versa, it does not load again. I am trying to populate the listview with items from sqlite database. Here is my code:

Attractions.java

public class Attractions extends ListActivity {
DataBaseHandler db = new DataBaseHandler(this);
ArrayList imageArry = new ArrayList();
ContactImageAdapter adapter;
int ctr, loaded; 
int [] landmarkImages={R.drawable.oblation,R.drawable.eastwood,R.drawable.ecopark,R.drawable.circle};
String []landmarkDetails = { "Oblation", "Eastwood", "Ecopark", "QC Circle"};

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_attractions);
    ctr  = db.checkContact(landmarkDetails[loaded]);
    db.deleteAll();


    // get image from drawable

    /**
     * CRUD Operations
     * */
    // Inserting Contacts
    Log.d("Insert: ", "Inserting ..");


    for(loaded=0; loaded 
        Bitmap image = BitmapFactory.decodeResource(getResources(),
                landmarkImages[loaded]);

        // convert bitmap to byte
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        image.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        byte imageInByte[] = stream.toByteArray();
        Log.d("Going to load images", "Image "+ loaded);

        Log.d("Goind to load objects", "loading");

        if(ctr == 0){
            Log.d("Nothing Loaded", "Loading Now");
            db.addContact(new Contact(landmarkDetails[loaded], imageInByte));}
            Log.d(landmarkDetails[loaded], "Loaded!");
            image.recycle();
    }


    // Reading all contacts from database
    List contacts = db.getAllContacts();
    for (Contact cn : contacts) {
        String log = "ID:" + cn.getID() + " Name: " + cn.getName()
                + " ,Image: " + cn.getImage();

        // Writing Contacts to log
        Log.d("Result: ", log);
        //add contacts data in arrayList
        imageArry.add(cn);

    }
    adapter = new ContactImageAdapter(this, R.layout.screen_list,
            imageArry);
    ListView dataList = (ListView) findViewById(android.R.id.list);
    dataList.setAdapter(adapter);
}

UPDATE

I ran the app on portrait mode: list present, when switched to landscape: does not display anything. I switch to portrait again: list present again.
