Re: [android-developers] Re: How to: Free to Paid App and retain preference and db files?
Hi, I want to ask something about LVL. From my brief understanding, LVL add additional code to check back with Google Play server and refuse to run if it was not a paid version. Is there possibility to have the check in Google Play server and not allow user to update if the copy installed is not a purchase version? This way, developer don't have to include LVL code in every app publish. Of course in-app billing is not applicable.

Re: [android-developers] Re: How to: Free to Paid App and retain preference and db files?
Hi, good to learn from all of you here. One of the usual request for the paid version is to remove ads and Internet permission. Some user just do no feel good about turning on Internet permission. If I implement in-app billing, the Internet permission will still be there since it already has it in Manifest so user would not be happy. Having a separate install file/key will still have the same situation. Next option is to add an export feature to the Free app like that Treking suggested so user can export it and import it in the Paid version. This is a good option but I am worried about user uninstalling the free app after purchase and thought the configuration and db will be automatically available. They might not even update to the latest free version that has the export feature. I was evening thinking to automate it in this way if the free app detected the paid app running during start to automatically backup the configure and put it in a sdcard location and when user start the paid version it prompt manually whether to import it if the preference has not been set or option in the menu for import. Then, if user uninstall the free version immediately after installing the paid version then the user will lost the ability to export. Do all these sounds complicated? Do you guys also implement LVL for paid app? If so, do we need to maintain a free version without the LVL code?

Yes, I have additional features for the paid version but was thinking to maintain the Ads in the free version.

[android-developers] Cannot populate List call from Main Class to Sub Class
Hi,
I try to explain my problem hope someone can help me point out the causes.
I have a TabActivity that has 2 Tabs MainApp.java and MethodB.java.
MethodB has code to populate a List, MainApp also populate the same content
but
filter out some column so from MainApp I call the method
MethodB.Test(String).
I cannot get the list populated. If I tab on Tab MethodB first and return
to MainApp Tab
I got the list content correctly display in MainApp.
-MainApp.java--
/*
If I call Test(String) in MainApp (MethodB.Test(String), the listview is
empty, if the list has been preciously initialise
in MethodB not calling from MapApp, the list is populated and if I call
Test(String) now in
MainApp the list is good.
*/
-MethodB.java--
/*
The Test(String) can correctly populate InitialiseListView
*/

events = new PasswordEventsData(mainContext);
try {
Cursor cursor = getEvents();
showEvents(cursor);
} finally {
events.close();
}
}

//Perform a managed query. The Activity will handle closing
//and re-querying the cursor when needed.
SQLiteDatabase db = events.getReadableDatabase();
Cursor cursor = db.query(TABLE_NAME, FROM, null, null, null, null,
ORDER_BY);
((Activity) mainContext).startManagingCursor(cursor);
return cursor;
}

[android-developers] Re: How to sort HashMap?
Hi DanH,
Although I'm a bit lost as Java is a very new language to me, I will
try to figure what you mean.
SimpleAdapter adapterShop = new SimpleAdapter(this, ppp,
R.layout.sort_by_name,
new String[] {name,age},
new int[] {R.id.name,R.id.age
);
I have this error -
The constructor SimpleAdapter(Directory, ArrayListSortable, int,
String[], int[]) is undefined
Not very sure about it.

The best advice I can give you at this point: stop. Just stop. Put your Android project on hold. Put hashmaps and arraylists and generics on hold. Now go get an introductory book on Java and play around with simple Hello World programs where you can familiarize yourself with the language and Eclipse. Knowing how to spot compile time errors and what they mean and knowing how to debug your program is *crucial* to you making any progress. This is a forum for Android SDK questions. You are asking basic Java questions. This thread could go on forever with multiple suggestions on how to solve your given problem but it won't make a lick of sense to you unless you understand the basics. --- -- TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

Yes. I try putting the textview but not success so i showing then plain buttons only. Nice, I will try your suggesting right away :) On Jan 5, 9:31 am, Mark Murphy mmur...@commonsware.com wrote: There is no TextView in your layout. The two main approaches for putting some widget at the bottom last line of the screen are: 1. Use a LinearLayout parent for the widget and the other stuff. Use android:layout_height=0px and android:layout_weight=1 for the other stuff. Use a regular android:layout_height for the widget and no android:layout_weight for it. 2. Use a RelativeLayout parent for the widget and the other stuff. Define the widget as having android:layout_alignParentBottom=true. Define the other stuff as having android:layout_alignParentTop=true and android:layout_above=..., where the ... is the ID of the widget.

Hi Kostya, The picture is clearer now after your explanation. I have an application server generating Latitude and Longitude in XML and I pullpurse it in my program to compare to current location. So I need to convert the Lat and Lon to Long so I can do a distant to current location calculation.

[android-developers] Re: String error...pls help to spot
Yes about distant. But I need to compare what the XML spit out which is String format. For example I want to do: m.setLatitude(seedLat); m.setLongitude(seedLon); float distanceInMeters = location.distanceTo(m); SeedLat/SeedLon are pullpurse from a XML source. So I need to convert them prior to the setLatitude/setLongtitude etc. On Jan 1, 9:53 pm, Kostya Vasilyev kmans...@gmail.com wrote: Ah.

When I check, Name did contain the correct value.
I remember array starts with [0] so I create another counter call i
with i++ to replace lv_arrr[i] = Name;
Somehow lv_arrr still contain null. Why is that so?

[android-developers] Basic String Array question :(
Sorry, if this is too basic and not entirely Android.. but android is
part java too, so I don't have to hop forum. I believe someone else
might encounter this too. I'm putting some statement in the Android
basically reading an xml file and cast the value into an array to be
use as listview but I encounter some problem. To keep thing simple and
readable, I simplify it as below:
String[] lv_arr;
for(int i=1; i11; i++){
lv_arr[i] = hello;
}
When I toast the value of lv_arr[i] it is null.
If I do this:
String[] lv_arr = {hello, hello, hello} + the for loop, I can get
the hello value when I do the toast.
but [3]-[10] is still null value.
Why is that so?

[android-developers] Re: Basic String Array question :(
Dear King,
array indexing is zero-based, so you would start your loop from 0 and
go to 9 (where i 10)
Right sir, I'm aware it's for illustration and I forgot to change it.
You've initialized an array to exactly three elements. Anything after
that
This part is essential, if I do not know how many element I have then
I cannot declare it predefine but declare array without value to be
filled later.
That is why I have a for loop to extract value from a XML field to
fill into the array. But the array seems to be null unless I have pre-
initialise it with something.
The for loop only fill the data for dummy value I put, if I initialise
3 dummy values the for loop fill exactly 3 values and leave the rest
empty. If i set set 5 dummy values, the 5 get filled correctly.
Java is not my native and I have read a few java books and written
full running android apps. Then, still unable to figure this out...
maybe I need some beer :D

If this is your actual code, you need to initialize the array.
String[] lv_arr = new String[11];
Second, array indexing is zero-based, so you would start your loop from 0
and go to 9 (where i 10).
If I do this:
String[] lv_arr = {hello, hello, hello} + the for loop, I can get the
hello value when I do the toast. but [3]-[10] is still null value.
You've initialized an array to exactly three elements. Anything after that
(index 3 and above) is non-existent.
These are really basic Java concepts. If you don't understand this, I highly
recommend you go study Java on it's own and figure this stuff out before
trying to do an Android project. You're going to run into a lot of headaches
if you try to learn both at the same time.

[android-developers] onResume is always called on TabActivity so onCreate is not necessary?
Is it suppose to work this way? I have a TabActivity with 3 tabs, each tab started an activity and I realise when a tab is clicked onResume is call. If I have onCreate, when app start it will launch onCreate and then onResume immediately. So, I can just get ride of onCreate in this case? Thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Loading raw resource text file hang...
I'm not sure... I've been using this in my previous app.
I change to this code instead and it is working.
---code---
TextView helpTxt = (TextView)findViewById(R.id.helptext);
helpTxt.setText(readTxt());
}
private String readTxt() {
InputStream inputStream =
getResources().openRawResource(R.raw.help);
ByteArrayOutputStream byteArrayOutputStream = new
ByteArrayOutputStream();
int i;
try {
i = inputStream.read();
while (i != -1) {
byteArrayOutputStream.write(i);
i = inputStream.read();
}
inputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return byteArrayOutputStream.toString();
}
}

This seems suspect. Shouldn't you be checking for null?

Right, it was suppose to be:

sBuffer.append(strLine + \n);
I don't know why it was change. Thanks you guys.

[android-developers] How to do this correctly in SQLite?
Hi,
I want to insert a String value call temp but I don't seems to get it
working for the INSERT INTO statement.
Anything wrong with the code?
This is the initialization to create table and insert some default
values into the table if the database doesn't exist.
Many Thanks.

db.execSQL(CREATE TABLE + TABLE_NAME + ( + _ID

FIELD5 + TEXT););
String tmp = temp;
db.execSQL(INSERT INTO + TABLE_NAME + VALUES (0 'A',
'Hello', '', + temp + , ''););

[android-developers] Re: How to get value from ListView onListItemClick?
Another question seeking help. When I click the listview item, I pop up a form as dialog format to enable user to edittext. All is fine, I have an option to cancel editing by calling removeDialog(ID1); But if the user click back (android key) instead of the cancel button and pick another item in the listview, the edittext will contain the old data. I think because back did not release the dialog and it recall the same thing again instead of re-inflating one with the newly selected data? How to solve this issue?

The fourth parameter (id) is _ID. The third parameter (position) can
be used with moveToPosition() on your Cursor to access anything else
you may need.
