Dear Experts, Technology God:

I have got a very challenge and difficulty requirement from my customer about Android Phone QR Code scanning function:
My customer wants below functions with Android Phone QR Code(two-dimension code) scanning:
1) First, when customer using Android Phone to scan one QR code( we can call this QR code A), it will pop up one window with one website link, so the customer can double click the link to jump to the Internet website(we can call this website A)
(This function is easy and already done by us)
2) Close after step 1, when the customer open website A with mobile phone Internet Explorer , this website A will automatic add one favorite bookmark to the mobile phone Internet Explorer so the customer can quick access to the website again
3) When customer using Android Phone to scan another QR code ( we can call this QR code B), it will pop up another window with another website link so the customer can click to jump to the Internet website B!
But here is tricky and challenge point:
The customer also want the website B can add one favorite bookmark to the mobile phone Internet Explorer ,but the same favorite bookmark as website A!!
This means the favorite bookmark will be same as one Navigation page and will store all the QR code website quick link!!
4) The customer also want all the QR code related link ,like the website A and website B above show can be read offline , means even Android Phone out of wifi or network connection , the customer can still access and read all the content of the website A and B by click the quick link on favorite bookmark of mobile phone Internet Explorer!

Based on my development knowledge and experience ,for the below requirement 2),3),4), it will need collaboration with mobile phone Internet Explorer supplier ,need mobile phone Internet Explorer supplier open some interface and embedding into some code with mobile phone Internet Explorer! And we also need consider the cost involved since there are different mobile phone Internet Explorer users are using on the Android Phone! It is very hard to collaboration with different mobile phone Internet Explorer supplier!

So I’d like to ask help from all the Experts, Technology God here, is there any possibilities to using one simple way to realize the above requirement, especially for requirement 2),3),4)?
Means is there any possibilities we can realize cross mobile phone Internet Explorer platform or bypass the Internet Explorer?

Great thanks in advance to all the experts who will provide any suggestions!
And if anyone who will provide solutions ultimately solve this problem ,we promise will send you some China traditional gift to you via international express for free!
Thanks again!

Trying to create an app, need some help
I am trying to create an android app that uses gmap. I want the user to be able to select predetermined starting and ending points and then be given directions between the two points. This is what i have come up with, but the map seems to be frozen and is not actually locating the points or giving directions. Where is my error?

Please post your question in English only.

Can you please help how to retrieve and display image from a remote sqlserver db to android app ?

Help how? You need to explain exactly where you are stuck with this problem. If you have not even started yet, then I suggest you go to http://www.codeproject.com/KB/android/[^] and read some of the excellent articles there.

I suggest you break your inquiry into smaller, more manageable parts, like:

1) Are you able to communicate with the remote system?
2) Are you able to connect to the remote db?
3) Are you able to display images?

Get each of those up and running, and the project as a whole should start coming together.

Guys i want to dial a code on button press
i.e. Check screenshot
when i will click on "New Button" it should show a pop up asking "How Much AMOUNT u want to transfer,

after enter amount

it should dial *123*03401234567*AMOUNT# USSD Code

please can anyone help?

http://i.imgur.com/z9s4WIG.png

Try this.
Use this in your manifest permissions:

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

And in your activity use this:

C#

Button new_button= (Button)findViewById(R.id.button_id);//check the button id in your layout xml 
new_button.setOnClickListener(new View.OnClickListener() {
     public void onClick(View v) {
     
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    String tel_number= "tel:"+"*123*03401234567*"+AMOUNT+"#";
    callIntent.setData(Uri.parse(tel_number));
    startActivity(callIntent);

      }
   });

Hope it helps. Please mark it correct if it is.

Thanks

Hi my name is Nick. I'm a college student for game art and design right now and I'm really getting into learning coding for both games and Android development. I really want to push myself and learn as much as I can. I've been running through codeacadamy's Java course to just start learning but would like advice on where else I should be looking for learning. I'm an artist so whole creative thinker thing, blah blah. But I'm always coming up with little tid bits of app ideas but I don't really know how to make any of them a reality. I was hoping that some of you could point me towards more resources and ways to learn AS MUCH AS POSSIBLE. I'm ambitious and am a quick learner. I want to develop a great app (who doesn't..) but I could use some direction on where to head to learn the most and how to become the best I can be. Advice on languages to learn, websites to visit to learn, places to get ideas to work off, general programming tips, ect. Whatever you can throw my way to help I'd love to hear. Feel free to overload me with info, lol I promise I won't crash Wink | ;)

I hope to gain as much info as I can and obtain it however I can. So whatever advice you can give to someone starting out I'd love to hear please. I appreciate your time to read this and hope with your help I'll eventually create a program or app that will make some sort of difference even if it's a small one. Code on!

Thanks,
Nick aka infamous X187Xx

I am ready to help you. Please contact me at irudayambics@gmail.com.

Hi,
Is it possible to recognize emotions(Happy,Sad etc) of user through capturing image of user on android mobile. Please help me out if any suggestion or have any source code of recognition of user mood in android. Thanks

I am really new into the whole android thing.I have always loved programming and its been a hobby. So, i started learning android couple of months back from the New Boston website. I just love the tutorials and now i have a dream to make my first app and see it in the hands of millions of people.Now, getting back to reality. I am also a fulltime college student which means balancing between my coursework and hobby. Now, i bet most of the experts may have gone through this management issues and can suggest me on my problem. My problem is that i get so carried away with developing my app that i forget to do my coursework and focus on my other programming languages(which i equally love). So, how do i actually not get carried away with my hobby and still make a fine balance between my coursework and my android app dream? Can you guys suggest some ideas which can help beginners like me to manage this sort of situation?

Self discipline! Make yourself a time-table to include both coursework and hobby - and keep to it!

Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

Please go through tutorials point for learning Android and go through the official Android web site for complete understanding of the concepts.

Take up a problem and try to provide solution using Android you will see yourself improving a lot in Android technology

The same way you manage anything in life: set priorities and timetables, and stick to them.
