Android SDK having trouble with ADB

You need library ncurses 32 bit version installed in your system

sudo apt-get install libncurses5:i386

In addition to libncurses5, you may require libstdc++6.

sudo apt-get install libstdc++6:i386

With the command

sudo apt-get install ia32-libs

You install a lot of libraries that is not useful to solve your problem.

Android SDK platform tools requires ia32-libs, which itself is a big package of libraries:

sudo apt-get install ia32-libs

UPDATE:

Below are the latest instructions from Google on how to install Android SDK library dependencies:

If you are running a 64-bit distribution on your development machine, you need to install additional packages first. For Ubuntu 13.10 (Saucy Salamander) and above, install the libncurses5:i386, libstdc++6:i386, and zlib1g:i386 packages using apt-get:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386

For earlier versions of Ubuntu, install the ia32-libs package using apt-get:

apt-get install ia32-libs
