Heard of the Sony tablets? We are not going to discuss anything about the tablets here, but I guess you noticed the names,Tablet S and Tablet P. It looks like since the the take over of Sony Ericsson, Sony decided to follow the same single alphabet naming procedure with their smartphones as well. The first Sony Xperia was named Xperia S (release in March 2012). There are rumors about ST25i ‘Kumquat‘ to get the name Xperia U and now we have another. This time it is LT22i ‘Nypon’.

Details emerge from the same source; and that is the Indonesian Telecoms Regulatory body. They claim that the LT22i Nypon will be called Xperia P on release.

LT22i ‘Nypon’ details:

• 1.0 GHz Dual-Core Processor
• ST-Ericsson NovaThor U8500 Platform
• 1GB RAM
• 4.0-inch (540 x 960 resolution) WhiteMagic display
• 8.1MP (1080p video recording) Exmor R back-illuminated sensor with LED Flash
• Android Gingerbread (2.3.7)

Play.com has delayed the release of the device which was previously decided to be on 30 January and the new date is scheduled to be 13 February. Another retailer, Clove confirms their release date to be in the first week of March with the stocks arriving on 6th or 7th March; that is just after the MWC 2012.

Xperia S

The new flagship of Sony Mobile Communications with a 1.5GHz dual core processor, 12MP camera capable or shooting at 1080p, 720 x 1280 HD display (4.3 inches) with Mobile Bravia Engine, NFC enabled and is PlayStation™ certified. The phone will run on Android 2.3 initially and will be upgraded to ICS later.

If you are not an iTunes™/iPhoto™ user, you can sync your Xperia™ content with folders on your disk or just simply drag and drop any type of files between your Xperia™ phone and your Mac.

Cool eh? There is more! We have some more exciting news to share with you, especially for those who in the past have raised the question “I’m a Mac user, how can I update my Xperia™ phone using my Mac?”.

We’re happy to announce that the Bridge for Mac will introduce SW update functionality in the coming release 2.0. Those of you who have previously used our Windows software, PC Companion, will recognize the SW update experience in Bridge for Mac: connect, get notified, accept and update!

 Great news!  Now what do I have to do, to put my hands on this Bridge for Mac?

You can already today download Bridge for Mac 1.2 from the download section of our support web, www.sonyericsson.com/support, there you will find all the details you might need to know about the application. Once the Bridge for Mac is downloaded and installed it will keep you automatically notified of future releases.

One more thing, don’t hesitate to discuss and share your queries related to Bridge for Mac or any other of our computer applications with the great community on Support Forum, check out the Software Download section.

Are you having problems getting under the current 50 MB upload limit imposed by Android Market™? Don’t let it be a roadblock in preparing your Android™ app for market. Instead, use these excellent tips for reducing the file size of your APK. David Karlsson, a software architect at Sony Ericsson, will get you all the details. Read more after the jump.

David Karlsson, Sony Ericsson software architect

Hi, I’m David Karlsson, a Sony Ericsson Software Architect. My work mainly involves giving architectural guidance and technical support to our development partners and third party vendors. One important developer topic that comes up frequently is how to reduce the APK file size of an app. Developers who are submitting apps to Android Market™ sometimes discover that their APK file exceeds 50 MB, the current upload size limit. But you don’t have to accept the APK file size as is. There are ways you can reduce your APK file size.

What is an APK file?

An APK is an Android application package file. Each Android application is compiled and packaged in a single file that includes all of the application’s code (.dex files), resources, assets, and manifest file. The APK file is basically a .zip file, so there’s no way of compressing its size any further.

Why you should consider keeping files as small as possible

Memory space on smartphones is often a competitive area, now that most users are storing music, video, messages are more, in addition to downloading apps. The smaller you make your APK, the better it is for the user, and that may be a deciding factor on whether to download your app, versus a similar app that takes up more phone memory.

Tips for reducing file size

Here are a number of recommendations for reducing static footprint. You can choose the ones that fit best for your own particular needs.

ProGuard

A tool for code shrinking, like ProGuard, will significantly reduce the static foot print. The tool is available at sourceforge. Note that it is very important to re-test all of the application after applying ProGuard since it may change the application behavior. As ProGuard replaces the application symbols, to make the code difficult to read, it is important that you retain the symbol mapping, so that you can translate a stack trace back to the original symbols if you have to investigate a crash in your application.

Removal of debug information

We recommend that you remove all debug-related functionality from the application. The application generally does not see or use this data, and the Android operating system does not require it to run the application. Hence, the debug information only wastes space, and should be removed.

To accomplish this, all debug related functionality must be enclosed in conditional blocks, like below:

static final debug = false;

if (debug) {

          Log.v(TAG, “Debug …”);

}

It is important that the debug flag is set at compile time (i.e. declared as static final) for the compiler to be able to completely remove all debug functionality. Creating your own debug method like the one shown below is not a good idea because the call to myDebugPrint() is not enclosed by a conditional block, which means that the compiler must retain information about myDebugPrint() in the calling class.

public void myDebugPrint() {

    if (Debug) {

              Log.v(TAG, “Debug …”);

    }

}

…

myDebugPrint()

…

Removal of debug symbols from native libraries

Using debug symbols makes sense if your application is still in development, and still requires debugging. But if debug symbols are still appearing when you compile a release build, and if you want to remove them, then we recommend that the Debug symbols be removed from native libraries (.so files). This is done using the arm-eabi-strip command, from the Android NDK.

Recommended media formats

If your application relies heavily on images, audio or video, another way you can reduce the APK size is by using certain media formats. We recommend that you use the following media formats for images, audio and video:

• Images: PNG or JPEG. Use PNGs; since it is a lossless format it is very suitable for textures and artwork as there will be no visual artefacts from the compression. If there are space constraints, use JPEGs or a combination of PNGs and JPEGs. A high quality JPEG image may work fine for large photo-realistic images, which the JPEG compression scheme is optimised for.
• Audio: AAC Audio is recommended for all audio resources. AAC achieves better compression at a given quality, compared to mp3 or Ogg Vorbis. Raw formats such as WAV should never be used. The common rational for using the WAV format is that decoding compressed audio streams usually means high latency at playback. However, Android provides the Sound Pool API which enables applications to use compressed audio streams without the penalty of high latency.
• Video: Use H264 AVC. Encode the video to a resolution no larger than the screen resolution of the target device (if known).

Optimise PNG sizes without losing quality

If you use PNG format, PNG images can be reduced in file size without losing quality. To do this, use a tool such as OptiPNG or PNGCrush. Both are great for reducing PNG file size while still ensuring image quality. PNGcrush is an open-source program that iterates over PNG filters and zlib (Deflate) parameters, compresses the image repeatedly using each parameter configuration, and chooses the configuration that yields the smallest compressed (IDAT) output. On the other hand, OptiPNG performs the trials entirely in memory, and writes only the final output file on the disk. Moreover, it offers multiple optimization presets to the user.

Use 9patch PNGs to scale your images

A 9patch png is a special format for PNG that can be used for backgrounds. Nine patch images are especially useful when designing buttons. Instead of defining a regular bitmap to be used as a background, a 9patch defines nine segments – for each of the four corners, the four edges, and the centre. (See illustration).

Segments defined for 9patch PNG.

When you use a 9patch image, the image is subject to the following conditions:

• The corner segments are never scaled.
• The edge segments are repeated along the edge of the in order to fill the edge between the corner segments.
• The centre segment is repeated to fill the centre of the background between the four edges.
• The illustration below shows two buttons. The background of each button is generated from the same 9patch.
  

  Example of buttons generated from the same 9patch file.

 A single 9patch PNG can be used to replace many background images, as it can scale to fill the size of the control. Equally, a single 9patch image can be used on all devices of the same dpi screen, removing the need for screen-dependent backgrounds.

Remove unused resources

Another potential group of space wasters to consider for removal from your APK file are unused resources in your res directory, such as unused layouts, drawables and colors. To detect unused resources in your APK which might be able to be removed, use the android-unused-resources tool. Android Unused Resources is a Java application that will scan your project for unused resources.

Avoid duplication

Making sure that your application doesn’t have duplicate functionality or duplicate assets is an obvious way to avoid having unnecessary files in your APK. It is important to understand which Android APIs you use, and the full functionality that each provides. It could be that one Android API is already doing the work of another API. Duplicated assets (strings, bitmaps etc) are also a waste of space, and can be easily avoided. To a lesser extent, duplicated code will also unnecessarily increase the size of the delivered binary.
