Android is a software development kit for mobile devices that includes an operating system, middleware and key applications. The Android SDK provides the tools and APIs that are essential for developing applications on the Android proposal by means of Java programming language.
1b. Describe THOUGHTFULLY how you learned the basic concepts and technique of developing applications for the Android phone Give two (2) examples from your personal experience of each learning process. (At least one paragraph)
Each Android application will work in its own workstation
By evasion, every purpose runs in its own Linux process. Android starts the progression when any of the applications code needs to be executed, and shuts down the process when it's no longer needed and system possessions are necessary by supplementary applications.
Every development will have its own virtual machine (VM), so the application code runs in separation from the code of all additional applications.
By default, each application will be assigned with a exclusive Linux user ID. Permissions can be set so that the application's files are noticeable only to that user and only to the application itself.
1c. Discuss in at least two WELL-DEVELOPED paragraphs your ORIGINAL personal insights about understanding know the basic concepts and technique of developing applications for the Android phone.
Android will come with a set of applications that comprise SMS program, email client, maps, calendar, contacts, browser, and others. All applications are written using the Java programming language.
By providing an open advance stage Android offers developers the capability to assemble awfully rich innovative applications. The developers can liberally take gain of the access location information, device hardware, run background services, add notifications to the status bar, set alarm and much, much more.
1d. Do you think this learning outcome is valuable or should it be changed? Justify your answer.
The course helped me a lot in learning core concepts of Android.
Be able to use the SDK and other development tools.
2a. Describe THOUGHTFULLY why it is important to be able to understand to use the SDK and other development tools. (At least one paragraph)
Developers have full right of entry to the structure APIs and tools used by the core applications. The application structural design is premeditated to make simpler the reclaim of mechanism; any application can issue its capabilities and any other application may then make use of those capabilities. This same method allows equipment to be replaced by the user.
2b. Describe THOUGHTFULLY how you learned and be able to understand to use the SDK and other development tools.
Android includes a set of core libraries that provides most of the functionality accessible in the core libraries of the Java programming language.
Every Android application executes in its own method, with its own occurrence of the Dalvik virtual machine. Dalvik has been written so that a tool can sprint numerous VMs proficiently. The Dalvik VM executes files in the Dalvik Executable (.dex) design which is optimized for least memory footstep. The VM is register-based, and runs classes compiled by a Java language compiler that have been distorted into the .dex design by the integrated "dx" tool.
The Dalvik VM relies on the Linux kernel for fundamental functionality such as threading and low-level memory management.
Give two (2) examples from your personal experience of each learning process. (At least one paragraph)
Android relies on Linux version 2.6 for core system services such as, memory management, security, process management, driver model, and network stack. The kernel also acts as an notion cover linking the hardware and the rest of the software stack.
2c. Discuss in at least two WELL-DEVELOPED paragraphs your ORIGINAL personal insights about the use the SDK and other development tools.
A fundamental characteristic of Android is that one application can make use of basics of other applications (provided those applications allow it). For instance, if your application wants to exhibit a scroll roll of images and an additional application has developed a appropriate scroller and made it accessible to others, you can describe ahead that scroller to do the job, rather than broaden your own. Your application doesn't include the code of the other application or link to it. Rather, it merely starts up that section of the additional application when they require arise.
2d. Do you think this learning outcome is valuable or should it be changed? Justify your answer.
The course helped me a lot in learning core concepts of SDK's.
Know the basic concepts of Android phone features and capabilities.
3a. Describe THROUGHTFULLY why it is important to understand about the basic concepts of Android phone features and capabilities. (At least one paragraph)
Android phone features and capabilities are as follows:
Storage SQLite, a trivial relational database, is used for data storage purposes.
Messaging MMS and SMS are existing forms of messaging, including threaded text messaging and now Android Cloud to Device Messaging Framework (C2DM) is also a part of Android Push Messaging service.
Connectivity Android ropes connectivity technologies counting GSM/EDGE, UMTS, IDEN, Wi-Fi, CDMA, Bluetooth, LTE, EV-DO and WiMAX.
Java support While Android applications are written in Java, there's no Java Virtual Machine in the stage and Java byte code is not executed. Java classes get recompiled into Dalvik executable and run on Dalvik virtual machine. Dalvik is a particular virtual machine premeditated purposely for Android and optimized for battery-powered mobile devices with partial memory and CPU. J2ME support can be provided via third-party-application such as the J2ME MIDP Runner.
Handset layouts : The proposal is flexible to bigger,Â VGA,Â 2D graphicsÂ library,Â 3D graphicsÂ library based onÂ OpenGL ESÂ 2.0 specifications, and traditional Smartphone layouts.
3b. Describe THOUGHTFULLY how you learned basic concepts of Android phone features and capabilities. Give two (2) examples from your personal experience of each learning process. (At least on paragraph)
The Android OS can be used as an operating system for notebooks, cell phones and tablet PCs, together with the Samsung Galaxy Tab, Dell Streak and other devices. The world's first TV running Android, called Scandinavia, has also been launched by the company People of Lava.
3c. Discuss in at least two WELL-DEVELOPED paragraphs your ORIGINAL personal insights about the basic concepts of Android phone features and capabilities.
The updated Android OS now runs on the Linux kernel 2.6.27denotation stronger protection, enhanced solidity and a array of core applications enhancements. Android 1.5 currently packs SIM Application Toolkit 1.0 and features auto-checking and repair of SD card file-system. Just like the iPhone OS 3.0, Android 1.5 comes with the SDK 1.5 that adds new APIs which help developers form improved apps. More significantly, even if, new features for end users extensively develop the familiarity addressing most obvious omissions in the 1.0 release.
A number of features are basically catch-up of the iPhone's, like a new effective keyboard or enhanced mobile web browser. Others are intended to add extra knock through flashier eye candy, animated window transitions, smooth, accelerometer-based application rotations between representation and backdrop modes and largely shine of user interface elements.

4a.Â Describe THOUGHTFULLY Why It Is Important to understand Java programming as it related to application development for the Android platform.Â (At Least One Paragraph)
The Android applications will be written in the Java language, and will be compiled by the JDK's javac compiler (or comparable, like ECJ). This produces normal Java bytecode (.class files). These files will be then transformed into Android's .dex, for all sensible purposes just a unusual file format for Java classes. It is a improved design; an enhancement over Sun's 1994 design. But you can also take a GIF image and adapt it into the better PNG set-up, and both images will be absolutely equal even though the byte streams are entirely dissimilar.
4b.Â Describe THOUGHTFULLY How You Learned to understand Java programming as it related to application development for the Android platform. Give Two (2) Examples From Your Personal Experience Of Each Learning Process. (At Least One Paragraph)
From a technical position of study, we knew that Java as a whole is a phase. The Java programming composes of three vital fundamentals - Java as the programming language, the Java core libraries and the Java virtual machine. Java was for a literally whereas existed in market in three "flavors" like - J2ME (mobile java), J2SE (standard) and J2EE (enterprise). There were also other flavors which are not so representative "flavors" like the GNU Compiler for Java or GCJ which creates confined executable code by compiling Java source code which principally "do away" with the Virtual Machine. From a logical point of view Android gear the Java language, has a place of Java libraries and a Virtual Machine called Dalvik.
4c.Â Discuss In At Least Two WELL-DEVELOPED Paragraphs Your ORIGINAL Personal Insights about Java programming as it related to application development for the Android platform.
Â The Mobile Java or J2ME was around for some time. It has its pros and cons but it is reasonably mature and protected as a mobile phone software development platform. On the other hand, the Android front, Google has selected Eclipse as the initial IDE to use if you want to generate Android mobile phone software. Google have their hands full when it comes to Android. They need to address numerous things in sort for Android to be the platform of option when creating mobile phone applications.
