title: Can I use Java for building cross-platform mobile apps?
body: <p>I have read an article about Xamarin was buying RoboVM and enables developers to write mobile apps in Java for cross-platform. I am not sure if it is possible now to use Java for developing cross-platform mobile apps. Is there any reliable tools where I can write in Java for cross-platform mobile apps development? Is it a good choice to choose Java only for potential cross-platform mobile apps? I don't consider using C, C++, C# for that purpose since I have never been focusing on one of them. I apologize for the fans of those langauges. Or Is it a better choice that I better work with Java for Android apps and Swift for iOS apps? I plan to choose Java as a main language for all web apps, cross-platform mobile apps and robotic programming development.</p>
