Implementing Proguard Security with my APK

I want to configure proguard with my Application. But while doing so I am receiving the following problems :

[2013-09-24 12:27:46 - DemoProguard] Proguard returned with error code 1. See console

Here is my proguard-text file

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:
-dontskipnonpubliclibraryclassmembers

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}

Answer

try to add these line very first on our proguard.cfg file on your project as below:

-ignorewarnings 

if you have any annotation in your project so, please add next line as below

-keepattributes *Annotation*

and ensure your gradle file has minifyEnabled as false
