title: Android SDK's adb: 32bit or 64? hello-world failure
body: <p>I'm trying the simplest of the tasks, which is the "hello world" tutorial of Android Studio. I'm on a 32bit Ubuntu (14.04) and I downloaded Android Studio today.
  I got blocked when I try to run it, since adb isn't responding:</p>
  
  <blockquote>
    <p>com.android.ddmlib - Unable to detect adb version, adb output: /home/me/Android/Sdk/platform-tools/adb: 1:  /home/me/Android/Sdk/platform-tools/adb: Syntax error: ")" unexpected</p>
  </blockquote>
  
  <p>When I tried to run adb by hand I discovered that it's not 32 bit while I'm on a 32 bit platform. "file adb" returns:</p>
  
  <blockquote>
    <p>adb: ELF 64-bit LSB  shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=[something], not stripped.</p>
  </blockquote>
  
  <p>Did I miss some step where I could have picked the platform? Everyone seems to have the opposite problem, platform 64bit vs. file 32bit.</p>
