[Q] Crossover Application

Dear Team,
Does anybody had developed Crossover application to run android apk file on
Windows 6.5 ????
Regards
Jignesh

i did a quick lookaround (using google search) about your question and the only answer out there is that it can't be done (yet)
both OSs use completely different coding and packaging techniques making it virtually impossible to make them interoperable

[Q] learning app for kids - what language should I learn to developed it ?

Hello programmers
I would like to do learning app for kids
the app will include :
1- registration -> to show the score that he got from quizzes and also display hes friends score (like a competition between friends)
1.1 - registration can using facebook , twitter so he can invite his friends to the game and play with them.
2- voice -> to say the name of the items (numbers, alphabets, animals, foods ... etc)
3- some animations -> for the quizzes answers (correct or incorrect) and going to next quiz. Also for menu
4- moving items by user -> to move the items (answer) to the correct picture
what languages should I learn to do this app?
I know Java , also I have create some basic apps for android from android tutorials like note , Calc and many basics app
but the design is regular android design
so for my app it needs other design for kids and it need be more colorful (including with any event user make)
I'm good designer using photoshop but I don't know how to get the sizes for the android layout and items sizes
also for registration : do I need to make database using sqllite ?or I have to create database online "mysql" for example ? or if i do registration via facebook only so I'll get the database from facebook ? (I haven't try to do facebook apps before)
as I said before the registration is only to display the score between user and his friends
for moving items (answers) to the correct pictures . is it the same way when I do it using JFrame in java ? so I just need to do an object then control it wit MouseMotionListener then mouseDragged and mouseMoved . what are the names for the events, interface listener and functions in android
about the "Voice": is there a website that I can download the sound for most of Items (numbers, alphabets, animals, foods) for free ? or should I create it by myself ?
also is it better to create many sound files? Or using Text-To-Speech (TTS) ?
I know how to play a sound file in my program
but if you suggesting using TTS can you please give me a link to learn how to use it
my question again .. what exactly should I learn to do this app with the details the I gave above ?
what I mean is don't please tell me you should learn for example Java tell me what I have to learn in java for android
such as what are the names for the events, interface listener and functions in android for MouseMotionListener - mouseDragged and mouseMoved
thanks

For graphics check Google's design guidelines. You can set any image as the background of a view. So being good at Photoshop is great.

I think that you will need to use Sqlite databases. You cannot handle other ones in Android (Ok. Maybe with some libs)
However, sometimes it can be done with files, too. That would mean maybe encrypted text files.

Use Android DPI Calculator to get the translation from pixels to dip for all screen resolution. You just input a width and/or height in pixels and it gives you the translation and even tells you if you'll get half pixels
For the APIs codebase, I guess the documentation is the the best place to look if you already know java : http://developer.android.com/guide/components/index.html
Here is a good tutorial on how to achieve "drag n' drop" : http://www.vogella.com/articles/AndroidDragAndDrop/article.html

[Help] App development

I'm making a Java project for school to the final tests, and I need good Guides and Documentation.
The purpose is to make a Remote Control App.
Here is the problem, I don't really know how can I communicate from the PC to the App, And I just started to learn how to make Android apps .
I know how to control the PC if I get the correct variables (I attempt to use the ROBOT in java).
The things I need to learn is:
How I create a network (LAN based) between the PC and the App.
How to make an App that can bee used for those purpose.
Thanks to any one who help :laugh: .

[HELP] Android unlock mechanism

Hi,
I'm new in Android environment, but I have some experience with Java programming. I want to try some mobile apps, so i started to writing my first game. Everything is ok, but I don't know how to create mechanism like in "maze" Android unlock screen (can't put any link with photo ). I have list of points on screen and I want to give user ability to draw a path between these points. I've heard that there is special listener for this, but I can't find that.
Thanks for your help and sorry for my English

Don't know it at the top of my head either, but checkout the source of this lockpattern library, I'm sure you can find out how they did it

Using Dual-Camera to produce a stereostopic view in realtime

Hey there,
I tried to create an app with the HTC One M8 and it´s Duallens "depthsensor".
The problem is that there is no way to activate the second rear camera in android.
In android.hardware.camera package there are some hidden methods like : enableSubCam...so I´ll tried to use java reflection to activate these SubCam, but it doesn´t work at all...
I need some depth information in realtime for my application and I thought with the new DualLens this would be possible.
Also I tried to understand the HTC DualLens SDK, but all this stuff works on an jpg format and without creating an new depthMap
So what do you think is the best method to access 1. the second rear camera or 2. directly some kind of depthMap with help from HTC SDK?

i remember there was an app (german) that take 2 pictures at the same time from both rear cameras but the app was just to show that both work so it was like open app>automatic capture>save both pictures>exit.
got it : http://forum.xda-developers.com/showthread.php?t=2722352

yeah I´ve seen this app, but it´s hard coded on the linux kernel ...
and like I said I´ll try to calculate the depthMap in realtime, so a continious Depth-Matrix with opencv for example and not just a jpg
isn´t there a possibility to access the hardware components of an smartphone and activate them?

Maybe this will help you
Code:

like I said in the first post, I´ve tried to understand the SDK, but in my oppinion it´s not for creating a file...
you´re just allowed to use the already created depth information of an jpg-file...
or has anyone made some other experiences with the SDK?

Have you solved the problem?
Hi,
I have the similar situation and would like to know if you have found a solution to this problem.
I agree with you that the SDK provided by the HTC website is for depth info extraction from already created image. The SDK is not viable for realtime depth processing.
Please let me know if you have the solution for this problem.
Thanks!
