Unable to build Android+Scala project using sbt+sb

问题:

I can't build Android + Scala (and IntelliJ Idea 12) project using sbt and sbt-android plugin. I installed everything needed and added ANDROID_SDK_HOME to both .bashrc and /etc/profile but:

me123@ubuntu:~/Documents/android_projects/my-android-project$ echo $ANDROID_SDK_HOME
/home/me123/android-sdk-linux/sdk

me123@ubuntu:~/Documents/android_projects/my-android-project$ sudo echo $ANDROID_SDK_HOME
/home/me123/android-sdk-linux/sdk

First, doing sudo echo $ANDROID_HOME will be exactly the same as echo $ANDROID_HOME, because the variable will be replaced by your shell before executing the command.

Then, you most likely have a permission problem. Try running this to make sure you have the right ones :

$ chmod -Rv 700 /home/me123/Documents/android_projects/my-android-project/
