Java 7 language features with Android

Question

Just wondering if anyone has tried using new Java 7 language features with Android? I know that Android reads the bytecode that Java spits out and turns it to dex. So I guess my question is can it understand the bytecode of Java 7?

Answer 1

As of the Android SDK v15, along with Eclipse 3.7.1, Java 7 is not supported for Android development. Setting the source compatibility to 1.7 mandates setting the generated .class file compatibility to 1.7, which leads to the following error by the Android compiler:

Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties.
