Error conversion to Dalvik format failed with error 1

UPDATE: This issue was fixed in SDK Tools 17. If you have SDK Tools 17+ the solution here will not help you.

There is a bug in the latest Android SDK Tools (revisions 12, 13, 14, 15 & 16) which cause the following error:
Error conversion to Dalvik format failed with error 1
when you try to export your Android application & got Proguard enabled.

Google will probably fix it within few days, until then DO NOT UPDATE to Android SDK Tools revision 12. Someone already opened a bug on this issue.

Solution 1 - Restore SDK Tools v11 (ugly but it works):
If you did upgrade, the instructions how to install Android SDK Tools v11 on top can be found here. I did something similar which I think is safer & easy to undo:
1. Download Android SDK Tools v11 installer from here:
2. Rename the existing Android SDK\Tools folder to Tools-v12
3. Open the installer using 7zip, go to folder $_OUTDIR, and copy the folder 'Tools' the the position under Android SDK folder.

Solution 2 - Upgrade to Proguard 4.7 (needs to be reapplied after every SDK Tools upgrade):
Manually update Proguard to version 4.7. You'll have to do it again after each update of the SDK Tools.
1. Download Proguard 4.7 (zip):
2. Extract the folders "bin" & "lib" from the zip on top the existing Proguard installation in the SDK Tools Proguard folders "bin" & "lib", should be around here (Win x64):
C:\Program Files (x86)\Google\Android SDK\tools\proguard
