Oracle has announced that they stop the official updates for JRE 7 and JDK 7.
As much as I know, Google doesn\'t say anything about JDK 8, I guess the recom
It looks like Google doesn't officially support the JDK 8 for Android development. See paxdiablo's answer.
But let me add some thoughts.
I wanted to try using the JDK 8 anyway. So I downloaded and installed it, and used it (and Apache Ant) to build a simple Android app.
The app doesn't use any features which are new to Java 8, such as lambdas. In addition, Ant passed a parameter to javac asking it to emit bytecode compatible with older JREs.
The app compiled fine.
The app requires that I root my phone before running it. I haven't done so yet, and haven't tested the app yet either.
Please ping me with a comment in a few weeks. Ask me to update this answer and to let you know whether or not the app worked.
