Ok, it is generally best practice to use Ubuntu for building android but if you are a Gentoo fan and don’t want to mess with a vm you’ll have to bypass some bumps first.
So let’s start. Firstly you need sun-jdk6. icedtea-jdk won’t do the trick. So let’s get sun-jdk6 firstly. I’m going to just pass the commands you need and it should be self explanatory if you know what you are doing.
Download java and put it at /usr/portage/distfiles/
su- cd /usr/portage/distfiles wget http://uni-smr.ac.ru/archive/dev/java/SDKs/sun/j2se/6/jdk-6u45-linux-x64.bin
Then copy paste the exact same lines as below to auto-accept all licenses.
cat >> /etc/make.conf <<END
ACCEPT_LICENSE="*"
EMERGE_DEFAULT_OPTS="${EMERGE_DEFAULT_OPTS} --autounmask=n"
END
Then let’s unmask sun-jdk. It’s masked for security reason but we really need this. So edit package.unmask with your favorite editor ( vi /etc/portage/package.unmask ) and add at the bottom
=dev-java/sun-jdk-1.6.0.45
Ok we’re ready let’s emerge
emerge dev-java/sun-jdk
After you’ve done select the appropriate package by issuing
java-config --set-system-vm sun-jdk-1.6
Afterwards let’s emerge all the packages we need to compile android.
emerge git app-crypt/gnupg flex bison gperf libsdl wxGTK squashfs-tools curl ncurses zlib schedtool perl-Switch zip unzip emul-linux-x86-baselibs emul-linux-x86-compat emul-linux-x86-cpplibs
You should be all done expect one last thing. repo sync etc. and before you start your build goto core/config.mk and comment out the following lines.
+#ifeq ($(wildcard $(HOST_JDK_TOOLS_JAR)),) +#$(error Error: could not find jdk tools.jar, please install JDK6, \ +# Â Â which you can download from <a href="http://java.sun.com" target="_blank">java.sun.com</a>) +#endif
You are good to go! Happy android building!
