aapt missing but its there

Question

I had to reinstall ubuntu-14.04-64 due to reasons.

After this reinstall, when I try to build my android projets, I get a bunch of these lines (among others) in output:

java.io.IOException: Cannot run program "/home/gps/Android/Sdk/build-tools/23.0.2/aapt": error=2, No such file or directory

Now, I know this file exists in my setup because this:

gps@gps-HP-ProBook-4540s:~$ ls -l /home/gps/Android/Sdk/build-tools/23.0.2/aapt
-rwxrwxr-x 1 gps gps 1146608 Jan  4 18:47 /home/gps/Android/Sdk/build-tools/23.0.2/aapt
gps@gps-HP-ProBook-4540s:~$ file  /home/gps/Android/Sdk/build-tools/23.0.2/aapt
/home/gps/Android/Sdk/build-tools/23.0.2/aapt: ELF 32-bit LSB  shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=fc8aded5418584519d59f2133e81184fe3d4bdfd, not stripped
gps@gps-HP-ProBook-4540s:~$ 

I have installed all sdk tools from v19 onwards. Changing project settings to any of them shows same error.

Also, trying to execute the file directly gives same error:

gps@gps-HP-ProBook-4540s:~$ /home/gps/Android/Sdk/build-tools/23.0.2/aapt
bash: /home/gps/Android/Sdk/build-tools/23.0.2/aapt: No such file or directory

Can someone suggest a solution to this problem?

Answer 1

Problem solved as follows:

Issue was missing 32 bit libraries, libc and zlib in this case. Installed using following :

sudo apt-get install libc6:i386
sudo apt-get install zlib1g-dev:i386

Thanks @Joni for clear directions.

Answer 2

You're probably missing some dynamic link library that the program needs. Run this command to list the libraries it uses and install those that are missing:

ldd /home/gps/Android/Sdk/build-tools/23.0.2/aapt
