Android Group Japan website and Google Group are trying to bring together Japanese developers and support each other.

Twitters use the acronymos #agj for Android Related Discussions, and there many of them. 

Several books are already available:

Just bumped into zxing project, and wanted to share.

According the Project Home page:

ZXing (pronounced “zebra crossing”) is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. Our focus is on using the built-in camera on mobile phones to photograph and decode barcodes on the device, without communicating with a server. We currently have production-quality support for:

• UPC-A and UPC-E
• EAN-8 and EAN-13
• Code 39
• Code 128
• QR Code

Now I have to think of an implementation that will use QR Codes…

I am sorry to announce that the Html project is postponed to a later date.

Would like to complete the 2Chan browser as soon as possible, and although an Html parser would have been nice, it is not really necessary. For the 2chan browser, the parser required is quite simple and can be accomplished by a dedicated parser.

Again, sorry, and I do promise to continue this project at a later date.

One more comment on Nekohtml: If you are familiar with it, you know it requires Xerces, therefore the porting project should start from that. There is a guy who claimed he has done that, but I couldn’t find any link to the ported lib.

The Android Logo (AKA Droid Robot) was modified. Original logo is shared by Google and used according to terms described in the Creative Commons 2.5 Attribution License.

The SAX XML parser will work great till it encounters an XML error, a mismatched tag as an obvious example. The parser will throw an exception. You can implement the warning and error functions, but it will not help, the exception will still occur, halting the parsing process.

Therefore, the only solution is to import an external HTML parser to Android.

I have searched, read, compared and decided to use NekoHtml . Not sure how the programming team selected the name, but looks like a strong implementation.

I will document all the steps I take to include this library, until the hopefully succesful outcome.

Step 1: Download NekoHtml from sourceforge

Still a mere place holder, but I hope to start Check-Ins in the next week.

The inspiration came from different Linux 2chan browsers as Kita2 and JD 2ch (both available for Ubuntu, using Synaptic), as well as Gikolet.(J2ME)

It is still not decided if I will reuse any of the code mentioned above. Kita2 was written in Ruby, Gikolet in Java but looks like the porting effort will be more difficult than rewriting it.

Stay tuned for this project progress as I expect I can provide a prototype in a few weeks.

Image jpegImage = Image.createImage( jpegByteArray, 0, arrayLength );
if (jpegImage == null) {
//ERROR
} else {
jpegImage.getRGB (argbArray, 0, jpegWidth, 0, 0, jpegWidth, jpegHeight);
}

Since Android does not have an Image class, the following code will produce the same results (Please note the similar API):

Bitmap jpegBitmap = BitmapFactory.decodeByteArray(jpegByteArray, 0, arrayLength);
if (jpegBitmap == null) {
//ERROR
} else {
decodedBitmap.getPixels(argbArray, 0, jpegWidth, 0, 0, jpegWidth, jpegHeight);
}

Not that different, isn’t it?

(And I know I need a better blockquote for code… working on it)

Now, when someone (like me) intends to implement a UI with some  networking threads and processing, the two options are:

1) Running the Networking as a Service

2) Spawaning threads from the UI activity.

The two options are not that bad, it is just that using a Service model is an overkill for most applications, and having one activity which manages everything – UI as well as tasks seems like the easier solution.

When I started, I assumed an Activity can be anything, but as clearly stated:

(an activity that is not visible to the user and has been paused) is no longer critical, so the system may safely kill its process to reclaim memory for other foreground or visible processes

Sorry for not posting code, but this project is not an Open Source.
