Take the 2-minute tour ×  I am having a problem trying to
obfuscate my project with proguard.  I am exporting my project
with eclipse, the project is on android 2.2 sdk, the
default.properties are :   I am getting this error when I am
trying to export the project:  Error: Unknown option '..(some
ASCI symbols)... mykey ...(some ASCIIsymbols)..' in line 1 of
file 'D:\workplace\keyfile', included from argument number 1  I
have exported other projects and none of them gave me this
error... How can I fix this?  share|improve this question add
comment  2 Answers  up vote 1 down vote accepted  It seems like
one of your *.properties files specifies   because it is being
read as if it were a ProGuard configuration file.  share|improve
this answer thank you for your answer, I solved the problem by
creating a new project and copying my files in it –  Cata Mar 22

proguard configuration.  -renamesourcefileattribute SourceFile
-keepattributes SourceFile,LineNumberTab
