Question

Is my first time using Proguard. I’m testing it in a example project with following code (Just for check when the stacktrace is obfuscated)

package com.proguardtest;

import android.app.Activity;
import android.os.Bundle;

public class ProguardTestActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    try{
        Integer.parseInt("Test");
    } catch (Exception e){
        e.printStackTrace();
    }
}
}

So I create a new project and go to the file:
default.properties and add the line

proguard.config=proguard.cfg

thats the resulting file:# This file is automatically generated by Android Tools.

# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system use,
# "build.properties", and override values to adapt the script to your
# project structure.

# Project target.
target=android-7
proguard.config=proguard.cfg

Then I try to generate the apk with the export wizard (Eclipse Windows) and at the last step when I have selected the path for the apk a error dialog appears showing Conversion to dalvik failed.

What am I doing wrong?

Thanks in advance

Upgrade to ProGuard 4.6 (download it, extract the .zip file, copy to ..\android-sdk\tools\proguard)
