The most smartphones have not even updated their OS to the Android 2.1 version, but it does not prevent Google from developing and debugging of the next version of its platform. So, mobile apps developers for Android will meet Froyo (it’s a code name of the 2.2 version). According to rumors, Nexus One will get this renewed OS very soon. The release has not yet announced, so there is no precise information about the updates. But here are some assumptions about future features of Android 2.2:
• JIT compiler,
• additional free RAM,
• OpenGL ES 2.0,
• Flash 10.1 support,
• corrected problem with the “crazy screen” (multitouch),
• activation of the color trackball,
• FM-radio.

Information about the JIT compiler can be considered as a confirmed fact, we can only wait for the details from Google, which has already provided a compiler for Android application developers to test their programs.
More additional free RAM will be available thanks to new kernels that Linux uses in Froyo. It was done in CyanogenMod previously, and it gives grounds to assume that such a feature will be used in Froyo.
We sure that you have already read about OpenGL in Android. So Android mobile application developers is still waiting for the full access to the OpenGL ES 2.0 libraries.

When can we expect the new version of Android? So, we hope that Google I/O 2010 will uncover this secret.
