Hi Experts,
I am a new to the android, and I am trying to work on Tab Action bar, but I find the below interface was deprecated , so what is the replacement, and what happen if I use deprecated interface?
ActionBar.TabListener
public static interface ActionBar.TabListener
android.support.v7.app.ActionBar.TabListener

Thank you,
But I checked the link common navigation pattern in the same page, but I didn't find any code, it is just an information.
Regards,
|
|
|
|

Yes, because it is just suggested patterns. You are expected to decide what you wish to implement and write the code yourself.

I would like to use Tab bar, so if I use deprecated interface, is there any problem?

I would assume it means you can't develop for Android 5 (API 21) or newer. If your target audience is older than that, you should have no problem.

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.

Post only relevant code next time.
The error text plainly states that jObj is null.

to remove error what i make
|
|
|
|

don't forget: use "pre" tags to format it
M.D.V. 
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!
