[android-developers] android bug gsm: NetworkOperatorName when returning to home network
Hi, When I roam in another network my android devices books into the GSM network of that Operator. The NetworkOperatorName is displayed and all is fine. However when I return to my home country the network name of the operator from the visted country is still present on my android devices Samsung 10.1n tablet android version 3.2 Samsung Galaxy 9000 android version 2.2 note: this is not network related I have explored all possibilites there. Additionally it is not sim related I have swapped out the sims between devices and different devices however same effect. I am sure of a way to reset the network name other than a hard reset of the device, however, this is very annoying I loose everything. I will look into TelephonyManager but I do not expect to find anything together with eclipse trace. Can you help, program wise or other thanks graham -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] customAdapter how to print out content of array in TextView.setText() of getview
Hi,
I have written a CustomAdapter to display a list of hash key+value
items as a list. But I am stuck on the line below.
label.setText(my_VALUES[0])
Class two is my CustomAdapter and I am passing it a hashMap
public MyCustomAdapter(DynamicLists dynamicLists, int row,
HashMap data)
here I combine key+value pairs and I assign them to an array called
my_VALUES. But I don't know if this is correct?
How can I print out each KEY+VALUE pair as a seperate item in getview.
at the moment I can only use label.setText(my_VALUES[0])
Thanks
graham

[android-developers] How to creating a custom HashMapAdapter
Hi, If I have a hashmap containing the following how can I instantiate a custom adapter. The custom adapter should extend baseadapter. Hashmap contains (String,String) I need to combine both key and value so it looks something like "KEY+VALUE", "KEY+VALUE" and assign this to an array VALUES. The array VALUES is used later on when I insantiate my custom adpter Instantiation should look something like this MyCustomAdapter adapter = new MyCustomAdapter(this, android.R.layout.simple_list_item_1, VALUES); setListAdapter(adapter) I am lost here so code would be a big help.

Re: [android-developers] Re: CAN SOMEONE PLEASE HELP with hashmaps thank you
Hi,
So I have something like this now
*
public class listmodified extends ListActivity implements OnGestureListener
{
//public ArrayList myList = new
ArrayList(Arrays.asList(items));
public Map myHashMap;
{
String Result="";
myHashMap = new HashMap();
myHashMap.put(1, "one");
myHashMap.put(2, "two");
myHashMap.keySet().toArray();
myHashMap.values().toArray();
Result = ": + myHashMap.keySet().toArray() +
myHashMap.values().toArray()";
}
I probably need to iterate over the hashmap and populate items with
Result. Items could be declared outside of the brackets as
public static String[] items={};
*

Re: [android-developers] CAN SOMEONE PLEASE HELP with hashmaps thank you
Thanks Justin,
Order is not important, as my end goal is to present to the user a simple
list of values + keys. When the user longclicks on an item it will be
deleted from the hash.
What would you suggest?

[android-developers] CAN SOMEONE PLEASE HELP with hashmaps thank you
Hi,
I have a hashmap with key, value pairs example :-
(msisdn,value)
43664xxx,2
43665xxx,3
now I want to display this information in a ListView but I don't know
how to feed the data to an ArrayAdapter.
HERE IS MY ADAPTER, note I want to replace myList with data from the
Hashmap a concatentated key+value.
1. Pass the above hashmap as an adapter, replacing myList with the
hashmap
adapter=new
ArrayAdapter(this,android.R.layout.simple_list_item_1,myList);
setListAdapter(adapter);
Note this is what I have without using the hashmap

Re: [android-developers] Native SIP Supported on all ICS Devices?
Hi,
I have been playing around with the sipdemo and I have created simple
application. The
application creates SIPManager object and attempts to connect using
SipProfile to sip2sip.info.
This doesn't work either from the phone (Samsung Galaxy 2 running 2.3
Android) or the emulator.
I get back sip manager not supported, voip not supported in toast message.
Does anyone know how the library would be disabled on phones by an
operator, or what I think the phone vendor?
The support of SIP is important for next genration handsets. ( google IMS)
Without such stuff like LTE and IMS style applications will be limited to
appliacations running on PCs such as a broadband access cllient.
Cheers,
Graham

[android-developers] which to use shared preferences or files best practices
Hi all, I am trying to decide if I should use shared preferences or files for the following scenario. I want to present to the user a list of simple text strings which if selected will be used later in my code. Example Text string 1 Text string 2 User defined Text string If the user selects Text string 1 then this is used later on. A user may also define his/her own text string for later use. To store the text strings what would you recommend? A key/value pair using maybe ListPreferences or maybe text files. Thanks in advance, I hope the question is not too silly.

That's actually pretty good advice. Take a look at line 62. (I wonder why
you didn't identify that line for us, seeing as how you're asking for help)

Huh? I don't even understand this advice, much less endorse it. However,
every interpretation I put on this advice leads to a really bad idea, so
I'm going to suggest that whatever this advice means, you should not follow
it.
What you /should/ do is make sure that references point to something other
than 'null' before you try to dereference them.

What?
Maybe if there were some punctuation, capital letters, and complete
sentences in there I could understand what this guys is suggesting.
> when you do, fix it some way.
I agree with this advice, which boils down to the oh-so-insightful
suggestion that "analyze the problem, determine a solution!" That's good
advice, and I'm sure you'll find it exceedingly helpful.
Not.
NullPointerExceptions, like other RuntimeExceptions, are a result of
programmer error, in this case yours. It means that you have a pointer
still pointing to 'null', but you tried to use it as if it pointed to
something not 'null'. You have to assign your pointers to something not
'null', and you have to check your pointers before dereferencing them to
make sure they aren't 'null'.
As stated upthread, the stack trace (plus my hint) will tell you which
pointer was pointing to 'null' when you tried to dereference it.

[android-developers] PLEASE HELP . java.lang.NullPointerException when Service uses ArrayList
Hi,
I am creating service which will run in the background and contain a
blocking list (implemented using ArrayList) which may be used later
by other activites.
My Problem:-
>From my activity Services Demo I pass data to my service using
dataIntent.putExtra("originator", x);
this is fine but when I try to store this data in my Service in an
ArrayList called Items I get an exception and I cannot figure out
why.
The problem is in my Service code MyService :
if(items.contains(ORIG)){
Log.d(TAG, "Element already exists exiting ");
} else {
Log.d(TAG, "Adding Element");
items.add(ORIG);
}
Please help.

Re: [android-developers] Re: Problem with losing contains of ArrayList please help
Hi Shashi, Thanks for responding, from myphone i am calling querycontacts which presents to the user a button called block and textbox. Using querycontacts i am calling another class (now part of querycontacts) to populate an arraylist called items. I want to use this arraylist later as a blockinglist. However from querycontacts when I press the back button the state info is lost i.e. Arraylist is empty. So I cannot use it. I am guessing I need a service not an activity. Code would help me here.

[android-developers] Problem with loosing contains of ArrayList please help
Hi all,
I am new to Android programming and I am trying to write an
application which uses a blocking list based on ArrayList.
The class Querycontacts presents to the user contains to block.
Querycontacts calls ExtractContracts to add the number to an ArrayList
checking to see if the number is already on the list.
My problem :-
When I call QueryContacts from myPhone.java then any numbers added to
ArrayList items in ExtractContacts are lost. This is preventing my
from using the ArrayList items.
I am new to Android, so thank you for any help you can provide me.
Kind Regards,
Graham
