While installing the Android Emulator (SDK) by following this tutorial and applying these commands:

$ cd /opt

$ wget http://dl.google.com/android/android-sdk_r24.4.1-linux.tgz

$ sudo tar -zxvf android-sdk_r24.4.1-linux.tgz

$ cd /android-sdk-linux/tools

$ ./android

I got past the first two commands fine then when entering the third command:

$ cd /android-sdk-linux/tools

I got this error:

bash: cd: /android-sdk-linux/tools: No such file or directory

How can I fix the problem?

the command is incorrect. When you have completed the previous commands you are still in the directory /opt and android-sdk-linux is a subdirectory of it, and tools is a subdirectory of android-sdk-linux, so you cd to it like this:

cd android-sdk-linux/tools

without the leading /, which signifies the root directory right at the top. You can see that /android-sdk-linux/toolsdoes not exist if you ls the root directory

ls /

see? no android-sdk-linux here. But you see opt which is where you were before... That's why its location is /opt

If you are not in the /opt directory, (for example you opened a new terminal) you need to use the full path

cd /opt/android-sdk-linux/tools

The directory may possibly have a different name so do

cd /opt; ls

and you will see, if not exactly, then something like android-sdk-linux use the correct name:

cd android-sdk-linux; ls

now you should see tools

cd tools

and now you can run your executable.

Note: If you already closed it after step 6, to progress to step 7 in the tutorial, you should repeat the last two steps:

cd /opt/android-sdk-linux/tools

./android
