ubuntu13.04下安装jdk eclipse ADT

#tar zxvf jdk-7u21-linux-x64.tar.gz
#sudo mv jdk1.7.0_21/ /usr/bin/jvm
#gedit .bashrc
添加：
export JAVA_HOME=/usr/bin/jvm

export JRE_HOME=${JAVA_HOME}/jre

export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib

export PATH=${JAVA_HOME}/bin:$PATH

#source .bashrc
#java -version
显示：

java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

#gedit ~/.bashrc
添加：
# Android SDK
export ANDROID_SDK=/home/baoyu/Documents/Android/adt-bundle-linux/sdk
export PATH=$ANDROID_SDK/platform-tools:$ANDROID_SDK/tools:$PATH
#source ~/.bashrc

最后创建android project时可能没有R.java文件
