Guide to Compiling Android on Ubuntu 16.04 (Xenial Xerus) -- OpenJDK7 Installation on 16.04
Another Ubuntu release, another set of instructions to get Android source to compile. This only applies to the x64 (64 Bit version). It will not compile on the i386 (32 Bit version). Ubuntu has opted to dump OpenJDK7 in the Xenial Repositories. This just means we will need to add a custom PPA to install JDK7. Why go with OpenJDK7 and not OpenJDK8? Well, OpenJDK7 is required to build most popular AOSP 6.0.x ROM Sources as of right now, some examples include: DU, PN, Any Specific AOSP Tag, OmniROM, and Android-x86. In order to build anything >=4.4.x you will need Oracle Java 6. The only use case for OpenJDK8 would be those who only build CM (13+), PacROM (or any other CM derivative for that matter), or the 'master' branch of AOSP. Follow these instructions exactly (don't just throw 'sudo' around either, it is only to be used in specific cases): 1) Remove all traces of Java: sudo apt-get remove openjdk-* icedtea-* icedtea6-* 2) Add Xenial
