Today Flurry is used by 95000 developers across the globe and these 2 new features were really demanded by the users.

The crash analytics system allow to get notified on new crashes with an overview on the full stack trace  including symbolication. Flurry will compete with HockeyApp and Crashlytics (recently acquired by Twitter) in the crash report system battle.

The user acquisition analytics will help people involved in the marketing campaigns that will be capable to estimate the cost-per-click or the cost-per-install.

J2ME "on device debugging" with Sony Ericsson SDK

The Sony-Ericsson SDK provides you a tool to perform an on-device debugging of your J2ME applications.



After the SDK installation you can go to "Start" -> "Sony Ericsson" -> "Java ME SDK for CLDC"  and check the presence of two tools: "Connection Proxy" and "Device Explorer".



First of all you have to connect your Sony-Ericsson mobile phone to your pc. Launch "Connection Proxy" and press the "Settings" icon in the buttons bar. Select the COM port where your phone is connected to and press "Ok". Press "Connect" at the right top in the Connection Proxy software window. The "Status" frame below the device image should show the "Connected" status for your device.





Now launch the Device Explorer. It should start the synchronization with your phone. If it doesn't, start it manually clicking the "Reloading device information" in the buttons bar.

After a while in the left column you should see the list of application installed in your device. Now you can select the application you want to debug and start it.



The System.outy.print messages included in your code will be shown in the console window at the bottom of the "Device Explorer" software.





The tool can be used also to manage the application: install, delete, stop, pause, and resume it.

J2ME WTK Record Store deleted each time you run the application

Past days I experienced a weird problem building and running a midlet with Antenna inside Eclipse. Each time I built and run the application, the WTK "DefaultColorPhone" emulator I used had the RMS completely deleted. Everything was fine if I exited from the appliction and started again without any building.

The solution has been going to the Windows current user "Documents and Settings" folder and browse in "j2mewtk2.5.2appdbDefaultColorPhone". There I found a file in.use that was the lock for the existent RMS and that was the reason why the WTK generated a new clean RMS each time I built the application. Deleting it everything is ok again.

The new J2ME Wireless Toolkit 3.0: Java Platform Micro Edition SDK 3.0 (with built-in LWUIT library)

Sun has released the new SDK for Java Mobile Development which is the successor of the Java Wireless Toolkit 2.5.2 and the Java Toolkit 1.0 for CDC. As they say " It integrates CLDC, CDC and Blu-ray Disc Java (BD-J) technology into one SDK".

The reported key features are:

• Integration with 3rd party emulators and Windows Mobile devices


• On-device deployment and on-device debugging


• CLDC/MIDP, CDC/FP/PBP/AGUI and BD-J integrated into one SDK


• New CLDC HotSpot Virtual Machine


• Optimized MSA 1.1 stack with extensions


• Profiling support


• BD-J support


• New development environment based on Netbeans Platform


• Lightweight UI Toolkit (LWUIT) integration


• Device search database integrated in SDK

Some of the new features are really appreciated.

For example the MSA 1.1 stack with extension includes the following new JSR:

• Mobile Sensor API (JSR 256)


• XML API for Java ME (JSR 280)


• Java Binding for the OpenGL ES API (JSR 239)

Also the integration with LWUIT is a very good features. This SDK is is the first developer's kit that comes with a built-in LWUIT library, resource manager and demo application.

And last but not least, the integrated device database which is a built-in WURFL database search engine with thousands of mobile devices. More than 8000 platforms are accessible using the database in the SDK.

I haven't tried the new SDK yet but I will do soon. If anyone has already tried it please post a comment.
