17 October 2017   1511

This session is a fast-paced tour of the many options available for running Java EE applications in the cloud. It covers bare metal IaaS options such as AWS; PaaS options that provide native support for Java EE, such as Oracle Java Cloud Service/BlueMix; and everything in between. It also discusses how to deploy Dockerized Java EE applications to options such as Jelastic as well as running Java EE applications by using fat-jar solutions such as WildFly Swarm on bare JVM-based platforms such as Heroku. The presentation includes plenty of code examples and demos along the way.

Speakers are:

  • Rodrigo Bortoloto, Sr. Manager, CapTech Consulting
  • Ryan Cuprak, Analyst, Dassault Systemes

Android Studio to Receive Version 3.2

Since the announcement, the developers have completed more than 20 functions and made this version more stable

The company announced the release of Android Studio 3.2, which was available as a beta version for last 3 months. Since the announcement at the Google I / O 2018 conference, the developers have completed more than 20 functions and made this version more stable. The development environment is available for download to everyone.

One of the main reasons to take advantage of the development environment from Google is the Android App Bundle. Thanks to the new format, developers can create, sign and download only 1 object instead of a large number of APK-files for several devices. In addition, the App Bundle set reduces the size of applications.

The development environment from Google has received many new features, including the following:

  • Kotlin 1.2.61 with Android 9 Pie SDK support;
  • D8 Desugaring, thanks to which you can use the new features of Java even on older versions of Android. The function is enabled by default;
  • R8 Optimizer replaced ProGuard. With it, you can reduce the size of the Java bytecode. However, this is an experimental function, so the company does not recommend using it for applications release;
  • Emulator Snapshots - save the current state of the emulator. Subsequently, the developer will be able to run any of these saveings. It should be noted that the function is built on the basis of Android Emulator Quickboot, but Emulator Snapshots allows you to save and load saved states faster;

  • support for AMD processors in Android Emulator;
  • Energy Profiler - a tool with which you can evaluate the energy consumption of the application both during operation and when you are in the background.
  • System Trace - analog Energy Profiler. The difference is that instead of information about energy consumption, it provides data on the use of CPU resources.

In order to use the latest version of the development environment from Google, it must be downloaded from the official site. In addition, you need to install Android Emulator version not lower than v28.0.7, if you need Android Emulator functions during development.
