תכנות לאנרדואיד בקלות פרק 2 – רקע , התקנת סביבת העבודה והכלים הנדרשים

-
מבוא :
בפרק זה אנו נתקין את הכלים הנדרשים עבור פיתוח אפליקציות למערכת הפעלה Android ונבין את יחסי הגומלין ביניהם.
התקנה : (ישנם כמה שלבים, נא לעקוב ולהתאזר בסבלנות)
1. התקנת JDK – Java Development Kit
הורדה דרך הלינק הבא :
יש לבחור את הגרסא המתאימה למערכת ההפעלה שלכם,
בד"כ מדובר באחד משני :
Windows x86 88.36 MB  clip_image001 jdk-7u7-windows-i586.exe
Windows x64 90 MB  clip_image001[1] jdk-7u7-windows-x64.exe
כאשר windows x86 עבור מערכת הפעלה חלונות 32bit, ו x64 עבור מערכת הפעלה חלונות 64bit
2. התקנת Android SDK
הורדה דרך הלינק הבא:
3. התקנת סביבת פיתוח
בד"כ תעדיפו להתקין את Eclipse, ישנן עוד כמה אפשרויות כגון IDEA InteliJ, Netbeans אך Eclipse הינו ה IDE המומלץ וזה שמוביל את החזית בפיתוח כלים ותוספים אשר מקלים על תהליך הפיתוח.
הורדה דרך הלינק הבא:
4. הפעילו את eclipse, תחת window – preferences וודאו כי בלשונית של Android, המיקום של ה SDK מוגדר כפי שהתקנתם, לאחר שראיתם שהכל בסדר אפשר להתחיל לפתח.

Spinner VS AutoCompleteTextView

-
Image
       We’ve all been in a situation where we needed to show a list of some sort, a list which should be triggered by a user interaction (click, tap, etc..) A list is simple enough, probably even a spinner if we don’t want to spend that much screen real-estate on showing a list which the user clicks once and probably doesn’t need to see it after that. A spinner can be a real bug once there are too much entries for the user to choose from, how much is too much? that’s a good question – probably it differs from user to user, and probably this will have some performance issues with areal large number of entries, you cannot scroll forever to find what you’re looking for. A simple solutions for the problems mentioned above is an AutoCompleteTextView. it’s a control which is basically a combination of a TextView, EditText, and a Spinner all wrapped up in a single easy to use and configurable control. let’s see how it’s done:   first, in the layout file, c...

Utilizing Http response cache

-
     A typical mobile application will probably consume some resources from a web server using http requests. This repeated task has some drawbacks: Bandwidth has a cost, polling the same data over and over again results in a waste of user’s quota. the responsiveness and user experience is compromised once the user keeps waiting for data. If the requested data hasn’t changed on the server, then there’s no reason for us to fetch it. Of course, local caching of data is a must, but we also need to be able to refresh the data if it has changed on the server. A simple solution which comes out of the box for API 4+ is http response caching. Http response caching is a mechanism which enables us as developers to save a footprint of the response utilizing the abilities of the Http protocol. Basically, is holds a simple cache of the response which can be defined and enabled in code, and it prevents from fetching unchanged data from the server which was already fetched a...

ORM for android

-
     ORM – Object relational mapping has been around for quite some time now. Basically it’s a piece of software (regardless of targeted platform), which simplifies the connection between objects (as in OOP) and data in database (mostly used is tables based relational database), and it exists in order to help simplify bridging the gap between the two in our development process.     Microsoft's Entity framework is a great example for a robust easy to use framework which allows creating and querying the database from an object’s point of view with classic object oriented programming paradigms while maintaining all DB construction’s needs such as relationships between objects (tables) such as one to many or many to many including all the indexing, optimization etc..      In android, we have SQLite as a database platform, from simple to advanced application, it’s likely to assume that we’ll need some relational database to store and r...
