[Android] “Type R cannot be resolved to a variable” after Android SDK updated

If you get the error of “Type R cannot be resolved to a variable” after Android SDK and ADT updated. Try to find and install any available update in Android SDK.

In my case, after update Android SDK Tools rev 22, and also ADT. I get error of “Type R cannot be resolved to a variable” in my projects, and any new project!

- Start Android SDK Manager again. Two more update available, Android SDK Platform-tools and Android SDK Build-tools. It was not available in the previous update.

- Install the update packages.

- Close and restart Eclipse.

- Problem solved.

[Google App Engine] Using the updated Google Prediction API in App Engine applications

Although we can’t reliably compare its future-predicting abilities to a crystal ball, the Google Prediction API unlocks a powerful mechanism to use machine learning in your applications.

The Prediction API allows developers to train their own predictive models, taking advantage of Google’s world-class machine learning algorithms. It can be used for all sorts of classification and recommendation problems from spam detection to message routing decisions. In the latest release, the Prediction API has added more detailed debugging information on trained models and a new App Engine sample, which illustrates how to use the Google Prediction API for the Java and Python runtimes.

To help App Engine developers get started with the prediction API, we’ve published an article and walkthrough detailing how to create and manage predictive models in App Engine apps with simple authentication using OAuth2 and service accounts. Check out the walkthrough and let us know what you think on the group. Happy coding!

[Google Mobile] Collaborate and edit anywhere with the updated Google Docs for Android

As I was sitting on the ferry commuting to Google’s Sydney office this morning, two thoughts occurred to me. First, Australia is beautiful. If you’ve never been here, you really should visit. And second, it’s amazing how productive I can be with just my Android phone and an Internet connection. I was responding to email, reading news articles, and editing documents—just like I do at the office. Only the view was better!

We want to give everyone the chance to be productive no matter where they are, so today we’re releasing a new update to the Google Docs app for Android. We’ve brought the collaborative experience from Google Docs on the desktop to your Android device. You’ll see updates in real time as others type on their computers, tablets and phones, and you can just tap the document to join in.

We also updated the interface to make it easier to work with your documents on the go. For example, you can pinch to zoom and focus on a specific paragraph or see the whole document at a glance. We also added rich text formatting so you can do things like create a quick bullet list, add color to your documents, or just bold something important. Watch the new Google Docs app in action:



If you want to hear about the latest Docs news or send us feedback on the new app, visit Google Docs on Google+.

Gotta run—I’ve got another ferry to catch!

This new API lets apps show users what the people they know are doing or saying, in addition to their photos and contact information.

Calendar provider enhancements. Apps can now add color to events, for easier tracking, and new attendee types and states are now available.

New camera capabilities. Apps can now check and manage video stabilization and use QVGA resolution profiles where needed.

Accessibility refinements. Improved content access for screen readers and new status and error reporting for text-to-speech engines.

Incremental improvements in graphics, database, spell-checking, Bluetooth, and more.

[Google] Updated Google Search App for iPad

Google’s search app for iPad needed an update. That was especially obvious if you installed the Bing app, probably the best search app for iPad.

Now you can try the latest version of Google’s app, which adds a lot of useful features on top of the regular web interface. “We have added new features to make the app more interactive, more visual and to help you find what you want more easily,” explains Google.

You’ll see the results faster because Google Instant is enabled by default. Once you’ve clicked a search result, you can +1 the page, share it or highlight one or more keywords. To go back to the search results page, click the Google logo or slide the page to the right.

Google Image Search lets you see the results in a slideshow, an improved version of the similar feature from the mobile interface. “Tap on any image result to use the new image carousel, which lets beautiful images shine. You’ll see the image you selected expand, and you can easily swipe through the carousel to see other similar images.”



There’s also a new interface for Instant Preview that lets you explore the list of results in a visual way. The same interface is also used to display the search history.


The app is available in the App Store, but you can only install it if you’ve updated the iPad to iOS 4 or iOS 5. It’s a major improvement, but the Bing app is still more fluid, has more features and it takes advantage of the iPad’s capabilities to display maps and local search results.

[Linux] PiConvert updated!

Not long ago I POSTED about the wonderful imagemagick command, which provides image manipulation capabilities through a command line interface. As I described back then, when I write reviews, I usually take lots of screenshots to provide visual context, all of which are generated as PNG images by default. In the past, I used to manually convert all of those images into JPG format to reduce their size, but I also had to manually create thumbnails for all of them… Quite tedious, if you ask me.

PiConvert.sh

Using the extremely flexible and powerful imagemagick command, I created a script to automate some of the most common image manipulation activities I do. Originally, PiConvert.sh only converted PNG files into JPG, creating the corresponding thumbnails in the process. Since I completed the first version, though, I kept adding options based on my needs and now this simple script does a number of interesting things.

All available options are depicted in the screenshot below, which incidentally is the menu that shows up when the script runs.



BLACK AND WHITE CONVERSION

An interesting piece of functionality that I often use when an artistic vein kicks in, converting color pictures to black and white is also one of the most popular image conversions available. Unfortunately, imagemagick conversion is not the smoothest I have seen, but I wanted to make it available anyways.



A simple example of how a sample color image is turned to black and white using PiConvert.sh.



SEPIA CONVERSION

Converting color images to Sepia tones is another one of my favorites. In this case, imagemagick manages it better, and with the right setting, results look great.



For this example, I used the latest Fedora 15 default wallpaper, whose intense blue color makes the conversion to sepia stand out.




IPHONE & BLACKBERRY

When I find cool wallpapers for my PCs, it doesn’t take long before they end up in either my iPod4 or BlackBerry 9700. I thought PiConvert.sh could help me save some time there, so I added two new options to cover my needs there.

NOTE: The iPhone default screen resolution is a bit difficult to achieve with landscape wallpapers, so while I find a good way to do it, I am simply squeezing pictures to fit in. Not perfect, I know…

NOTE 2: I know, I know, PiConvert.sh code is anything but fancy, but I can hardly find any time to keep adding options. At some point I hope I will find time to optimize my code and remove any redundancies. For now, I just concentrate on getting it to do what it was designed to do, it is a very simple script after all…
