I am a java professional for the last 16 years.
I want to make mobile apps for both IOS and android.
Pl guide me.

I want to move from Java developer to mobile developer or a technology that will last for next 20 years.

iOS is a mobile operating system developed by Apple; it is a derivative of the Mac OS X desktop operating system, with which it shares many (but not all) common frameworks and other components. These include Cocoa Touch, the Mach/Darwin/XNU kernel and code from the Berkeley Software Distribution (BSD). Each iOS application runs in its own secure sandbox to prevent altering other applications, the operating system, or any other data.

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Mobile web development, also known as responsive web design, is an approach to web design aimed at crafting sites to provide an optimal viewing and interaction experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from desktop computer monitors to mobile phones). A site designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids, flexible images, and CSS3 media queries.
