Hello,
Can someone assist me with codes that I manipulates an android phone to take a vehicle number plate picture then extract the texts and maps it to the details of the registered owner.
Thanks in advance.

There are several libraries available for reading license plates. I used this one in my VanityPlates app. However, who that vehicle is registered to is not public information.

can I in any way obtain such source codes in android?

to remove error what i make

don't forget: use "pre" tags to format it

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

I have no intention of trying to plough through that unformatted code dump. However, it is highly likely that the following line did not return an object:
JSONObject jObj = jsonParser.makeHttpRequest(AppConfig.URL_Order, "POST", params);

Android introduced a CalendarView back in in API 11. I've implemented it in my app and it seems to work fine in the sense that it displays a perfectly normal-looking whole-month calendar and I can select a date and it triggers the appropriate event and I can read the selected date in my code with no problem.
http://i.stack.imgur.com/8nh9V.jpg[screenshot]
But I can't advance it out of the current month! The documentation says
A user can select a date by taping on it and can scroll and fling the calendar to a desired date.
(the "taping" appears in the documentation; I assume it's a typo for "tapping" )
I've tried flinging, swiping, scrolling and nothing happens. Is there something I need to do to enable this feature?
My XML looks like this:
<CalendarView
android:id="@+id/calendarView"
android:layout_width="match_parent"
android:layout_height="240dp" />
How do I advance the month on this? Thanks in advance!

I tried this on both an emulator and a real device. Scrolling worked as expected with no surprises.

Thanks for getting back to me. What kind of a device was it? I'm using a Samsung S Duos running Android 4.2.2. Is there any device setting that would disable "flinging" or horizontal scrolling? The calendar is in a layout with a bunch of other controls all in a ScrollView and the vertical scrolling works fine.
Unfortunately there's no easy way to test this in emulation because the app with the calendar is not stand-alone - it depends on other stuff happening on the phone that would be hard to do in emulation.

You need to isolate it to narrow down the problem. If it works being the only control in the layout, you then know where to focus your attention.

Which is why you need to create a dummy app to test with.

I'm looking for a good, active Android discussion forum. I've been posting questions to Stack Overflow but traffic for Android is a lot slower there than, say, for Windows programming so many of my questions get no response. (e.g., )[This question about advancing the Month in CalendarView)]
This forum on codeproject only seems to average less than 1 new question a day. Android is such a dominant platform with so many developers, where do they all hang out?
NB that the Google+ "Android Developers" forum suggested in the Google documentation is very low traffic probably because it's swamped by spam and totally unmoderated (the have a moderator but he hasn't been there in a long time).

Most people hang out here because they think CodeProject is a great place, so they tend not to care too much about what other forums exist. If you want to research alternatives then Google is the tool of choice.
Or, you could just post a proper question.
|
|
|
|
|
A Google search is how I found this. So far, using Google, I haven't found much else but given how many apps are written for Android, they must be somewhere.
I included a link to my post on Stack Overflow in my question but since it's already been viewed there 21 times in the last 20 hours with no answers, and this is a lower-traffic forum, I wasn't optimistic about posting it here. But at your suggestion I'll try it.

Stackoverflow has a decent level of response for issues with code. For general assistance on Android - I personally use the Google+ communities feature as this is where the Google Android devs and experts appear to be most active. Some specific technologies are more organised and have a slack channel (e.g. firebase), but I have not found one better than Google+.

I have app in side it only one activity (main activity) and layout XML of main activity have only
list view .this app get restaurants near from my location and display it in list view
What i need to do is add button to the main activity layout when i press on button get to me list of restaurant item by item
from json file and display it in list view but not display all restaurants in one click but show item by item
every click get restaurant
suppose i have 3 restaurant in json file
when i click on button for first click get me first restaurant
when i click on button for second click get me second restaurant
when i click on button for third click get me third restaurant
