After the android 4.0.1 source code is compiled successfully, run the emulator prompt "no command 'ulator' found ".

Test1 @ Ubuntu :~ /Working_directory $ emulator
No command 'ulator' found, did you mean:
Command 'qemulator' from package 'qemulator' (universe)
Emulator: Command not found

1. edit/etc/environment to add the directory where emulator is located (add the blue font content ):

Path = "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games: /usr/lib/JVM/java-1.6.0_27/Bin:/Home/test1/working_directory/out/host/linux-x86/bin"
Classpath = "/usr/lib/JVM/java-1.6.0_27/lib"
Java_home = "/usr/lib/JVM/java-1.6.0_27"
Android_product_out = "/home/test1/working_directory/out/target/product/generic"

Note: Logout is required to make the modification take effect.

 

In addition, the first startup time of the android simulator is too long and you need to wait patiently.
