Multidex Support / Training For Android Developers

http://snapvoip.blogspot.com/
Android application (APK) files contain executable bytecode files in the form of Dalvik Executable (DEX) files, which contain the compiled code used to run your app. The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65,536, including Android framework methods, library methods, and methods in your own code. Getting past this limit requires that you configure your app build process to generate more than one DEX file, known as . 
A multidex configuration, in Android development is the way to bypass the Dalvik Executable (DEX) limit of 65536 (64K) methods within a single DEX file, So you can build bigger and better apps that new environments like Android 5.0 (Android L) brings.

So Android Developer has published an article "Building Apps with Over 65K Methods" that guides developers through.

Multidex support prior to Android 5.0

Versions of the platform prior to Android 5.0 use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex bytecode file per APK. In order to get around this limitation, you can use the multidex support library, which becomes part of the primary DEX file of your app and then manages access to the additional DEX files and the code they contain.

Multidex support for Android 5.0 and higher

Android 5.0 and higher uses a runtime called ART which natively supports loading multiple dex files from application APK files. ART performs pre-compilation at application install time which scans for classes(..N).dex files and compiles them into a single .oat file for execution by the Android device. For more information on the Android 5.0 runtime, see Introducing ART.

APUS Launcher, Flying Like iOS on Android Devices.

APUS launcher, named after the extremely fast Swift bird (Apus), is a ultra fast launcher for Android devices. It said to bring the smoothness of iOS to Android devices. I of course have not felt the need for a third party launcher and I have kept ahead of the curve as I always court latest Android hardware and my applications are limited.
But the launcher seem to help Android phones that are below stellar hardware. APUS says it's launcher is able to save as much as 80% of a device’s memory over the stock launcher(s). The Apus launcher takes up less than 2MB of memory. This is good news for users with lower-end phones, which seem to lag no matter how much improvements are made to Android.. The launcher has a  ‘boost’ button that cleans up the memory usage by apps.
Originated in Beijing, China, out of a company lead by Tao Li, who was formerly a VP with Chinese internet security/browser giant Qihoo 360,plans to narrows the gap between Apple iOS' appeal and the Androids. Android L, Lollipop signals the that pretty soon it will eliminate the need for third party apps like OPUS, on the performance side. But people always like to test out new wall papers.
Opus is commanding a 30 million users/download according to the company and it was only launched in July this year. OPUS facebook page shows 670K likes. OPUS has garnered the top position on many Google Play markets.




You can find it in Google Play Store.

Android L (Android 5.0) Aka Lollipop Makes Your Phone, Tablet More Secure!

#AndroidL (Android 5.0) Aka  #Lollipop


Android L or Lolipop or Android 5.0, what ever the name you would like to call it, will bring a new life to your phone, tablet or other compatible devices. Whatever the destination, Lollipop brings a whole lot of improvements, enhancements and security to your device.
For an start, Google calls Lollipop as "the largest Android release yet."  and the truth is the latest version of Android OS  brings with it more than 5,000 new APIs. The developers have a much wider field the explore and create.

Of all the goodies Android 5.0 brings, some are more impressive, a sleek new user interface, cross platform support and improved performance via the new ART runtime engine. The Lollipop is also said to bring better battery life, improved notifications, OpenGL ES 3.1 and 64-bit support, among other features. Android 5.0 is bringing us a redesigned User Interface, with a new name, Material Design. Material Design is filled chock full of animations and layered elements to deliver a positive user experience. The new interface is designed to run on all supported devices,  from your smartphone and tablet to your laptop and also your Google TV. The Material Design supports elevation values, real-time shadows and lighting that gives a smoother 3D appearance overall.

Security is a big feature of Lollipop and all Lollipop enabled devices will have the encryption turned on by default. This will help to protect devices data from being accessed on lost or stolen devices or by eavesdroppers. Using Guest mode one can create multiple user accounts on the device allowing others to log in on your device, and at the same time preventing others from accessing your private data. For an extra layer of security, add the Android Smart Lock, which makes it easier to unlock your phone without having to constantly enter a pin or trace a pattern, making ones life easier. The new smart lock secures ones trusty device by pairing it with another trusted device you own, like Android smartwatch, Android powered car, or your own facial expressions, yes mick Jagger impression might work, if your tongue is long enough. Once the device recognizes a trusted, paird device, it could be unlocked, just by a simple tap.
Another layer of security to the OS is provided by the enforced the SELinux security module for all apps providing better protection against vulnerabilities.
Pair all those with “Factory Reset Protection” which requires a password before a phone can be reset. You can call it by another name if you want!, a “kill-switch”. This new function will prevent thieves and intruders from making use of stolen phones.
