Rooting your Android phone

You’ve got your smartphone. It’s new, shiny and neat. You can go online from it while you’re out and about and download cool apps to keep you company whenever you get bored. But can you download any app you want? What about custom themes? And did you ever feel like altering or replacing system applications and settings on your phone because they’re not so user friendly? Well, the thing is you can’t do whatever you want with your smartphone. For security reasons, phone manufacturers and mobile network operators impose software limitations. However, these limitations can be overruled by rooting your Android phone, although it is not advisable. Especially if you don’t have antivirus for Android installed, to protect you from mobile malware.

What Android 4.4 KITKAT version brings to you?

KITKAT or Android 4.4 is the latest version of android after JELLYBEAN. From the feature wise perspective KITKAT does not have much to boast.
In the  Android website, they say "Android 4.4 is designed to run fast, smooth, and responsively on a much broader range of devices than ever before — including on millions of entry-level devices around the world that have as little as 512MB RAM."

For developers they have introduced some new API's and tools to create responsive and memory efficient applications.

1.   RAM Memory Management:
A new API, ActivityManager.isLowRamDevice(), lets you tune your app's behavior to match the device's memory configuration. You can modify or disable large-memory features as needed, depending on the use-cases you want to support on entry-level devices.

           //Check if device is memory constrained
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
boolean lowRam = ActivityManager.isLowRamDevice();
if (lowRam) {
// Modify memory use behavior
2.   Tools for analyzing memory use:
Procstats is a new tool for analyzing memory resources your app uses, as well as the resources used by other apps and services running on the system.

SAPUI5 – Cross-platform tool for Mobility and Web

A light-weight programming model that connects easily with SAP, runs on client browser and typically an HTML page. One can create remarkable UI with SAPUI5 using very few lines of HTML and JavaScript code.

The main advantage of SAPUI5 is, it supports both SAP and non-SAP platforms.

  • Secure - SAPUI5 is essentially cross-platform compatible thus has increased security. SAPUI5 has indirect connection to the SAP server through SAP Netweaver Gateway, OData and the latest SUP (Sybase Unwired Platform).

Android Architecture

Android operating system is a stack of software components which is roughly divided into five sections and four main layers as shown below in the architecture diagram.
Android Architecture

Linux kernel

At the bottom of the layers is Linux - Linux 2.6 with approximately 115 patches. This provides basic system functionality like process management, memory management, device management like camera, keypad, display etc. Also, the kernel handles all the things that Linux is really good at such as networking and a vast array of device drivers, which take the pain out of interfacing to peripheral hardware.


On top of Linux kernel there is a set of libraries including open-source Web browser engine WebKit, well known library libc, SQLite database which is a useful repository for storage and sharing of application data, libraries to play and record audio and video, SSL libraries responsible for Internet security etc.

Android Runtime

This is the third section of the architecture and available on the second layer from the bottom. This section provides a key component called Dalvik Virtual Machine which is a kind of Java Virtual Machine specially designed and optimized for Android.
The Dalvik VM makes use of Linux core features like memory management and multi-threading, which is intrinsic in the Java language. The Dalvik VM enables every Android application to run in its own process, with its own instance of the Dalvik virtual machine.
The Android runtime also provides a set of core libraries which enable Android application developers to write Android applications using standard Java programming language.

Application Framework

The Application Framework layer provides many higher-level services to applications in the form of Java classes. Application developers are allowed to make use of these services in their applications.


You will find all the Android application at the top layer. You will write your application to be installed on this layer only. Examples of such applications are Contacts Books, Browser, Games etc.

Will Apple iPhone 5C survive?

Apple says Rs. 35000 is cheap.. but Indian Government says Rs. 20 a day and you are rich..

The iPhone 5c was supposed to be Apple's weapon to take on Android in at least the mid-level smartphone segment, if an entry-level pricing was never going to come to fruition. However, one look at the off-contract pricing for the iPhone 5s in various regions, and all those hopes can be put to rest.

The entry-level 16GB iPhone 5c without a contract has been priced at $549 in the US. That comes out to a whopping Rs. 35,000 at current exchange rates (1 USD = 63.65 INR) and does not include the duties and other charges that come in while pricing a product in India. If you were hoping for a sub-Rs. 25,000 pricing for the iPhone 5c in India, it's safe to say we won't see anything like that.

Strategy Analytics: Android claimed nearly 80 percent of Q2 smartphone share

Strategy Analytics Android represents nearly 80 percent of phones shipped in Q2
Multiple analyst groups recently gave us a look at second quarter smartphone market share by the manufacturer. Today, Strategy Analytics is breaking down that market share by platform -- and it's clear that Google is still on a roll. Android jumped 10 points year-over-year to reach almost 80 percent of the world smartphone market during the spring quarter, hitting a record high. Some of this rise came at the expense of Apple, which dipped three points, but most of the casualties were in the "others" category led by BlackBerry and Nokia's soon-to-vanish Symbian. Microsoft can claim a small victory, though. Windows Phone climbed slightly to 3.9 percent of the market in Q2, giving it a level of influence not seen in three years. While we're not necessarily looking at the new status quo for the smartphone industry, it's clear that the days of neck and neck competition are behind us.
