Some developers out there using library projects may be pulling their hair out after updating their developer tools to r14. A blog post has now appread on the android developers blog – here explaining a few matters.

We’ve also been experiencing a few problems, here were our solutions:

The project cannot be build until build path error are resolved – Try adding a dummy apk under Libraries, then remove it. You may be missing a apk lib definition in the project settings. Android Tools – fix project settings can also be of use.

Conversion to Dalvik format failed with error 1 – make sure there are no .jar files in the library project bin folder, this of course dpends on your choice of setup for the library project if your including source or source and resources.

Here is the presentation from this years Google I/O on protecting your app from piracy:

Google announced at their 2011 I/O conference that a major update is on the way to Google TV. Much of the current Honeycomb functionality will be ported to GTV, and most importantly there will be access to the Android Market. Here’s the presentation from this years Google I/O:

Here’s the presentation on Android Pro Tips from Reto Meier from this years Google I/O:

At this years Google I/O Wayne Pan presented a session on building a business out of an app through monitization with Admob. He also launched a new website www.guidetotheappgalaxy.com which details some of the ways developers can monitize their apps and gain business intelligence from relevent tools.

Root Tools is a new open source project aimed at making life easier for developers of apps that require root. The library already includes about half a dozen methods, including ways to remount, send shell commands, find busybox, and more.

Root Tools gives Rooted developers easy access to common rooted tools making their job easier when making rooted applications and making things standardized and better for the user.

In short, We all win. –Stericson–

The offical Android Honeycomb logo – Tron Bee.

The Google Announcement today showed us many of the Honeycomb features we’ve already had a taste of over the last few months. Many of the new widgets and SDK were mentioned by name. The column and stack widgets looked great. It was revealed that the UI flow we’ve been seeing has been created by the new render script API. This looks like its going to be a key tool for developers to give their apps the Honeycomb finish.

However the big announcements were the launch of the new Android Market website and in App payments. The previous website was a joke. The new Andoroid Market website at last brings the functionality and integration that users have been asking for. Its now possible to search for apps via the website and install them directly onto your registered phone(s). This functionality has been available for some time throught sites like AppBrain and AndroidZoom but the installation was never seamless. The google touch has now completed the web installation experience. Users can browse and buy apps and install them without having to confirm or press any buttons on the phone itself. Read more here.

The second big news was that in app payments will be suported with the SDK release expected in April. This will allow developers to charge for feature in the app itself. In may ways this provides and open book for developers to use it. Its not yet clear if this can be used for subscription payment – something thats been missing in Android over the iPhone for more than a year.

Its not possible to take a screenshot on Android unless you have a rooted phone. This is to protect users from malicious applications that could run in the background intent on stealing your personal information.
However, its still possible to take a screen shot of an application view programmatically by calling getDrawingCache().

The following code snippet captures the current parent view and its visible child views to a bitmap.

The bitmap can then be used by the application or exported to a file on the SD card.

Today Google released a preview of the Android Honeycomb SDK, Tech Lead Xavier Ducrohet had this to say:

Android 3.0 (Honeycomb) is a new version of the Android platform that is designed from the ground up for devices with larger screen sizes, particularly tablets. It introduces a new “holographic” UI theme and an interaction model that builds on the things people love about Android — multitasking, notifications, widgets, and others — and adds many new features as well.

Besides the user-facing features it offers, Android 3.0 is also specifically designed to give developers the tools and capabilities they need to create great applications for tablets and similar devices, together with the flexibility to adapt existing apps to the new UI while maintaining compatibility with earlier platform versions and other form-factors.

Here are a few more teaser screenshots.
