ksoap2 not compatible with ProGuard

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create Android software with ksoap2-android 2.6.1
2. Enable obfuscation in the project (i.e. turn on ProGuard) (you will need to 
use the option "-ignorewarnings" to get it to compile)
3. Use XmlPullParserFactory class to extract elements from the SOAP response
4. One class method (either newInstance(), newPullParser() or getEventType()) 
will cause an XmlPullParserException.

What is the expected output?
No exception

What do you see instead?
XmlPullParserException

What version of the product are you using? On what operating system?
ksoap2-android 2.6.1; Android OS 2.3.3

Please provide any additional information below.
The problem does not happen if the program is compiled without ProGuard.
The warnings/errors displayed when "-ignorewarnings" is off should be 
sufficient info for fixing the problem.
I did not get any more fine-grained in figuring out which XmlPullParserFactory 
method raised the exception (they are all currently in the same try block in my 
code), but that shouldn't be material to the errors.

You need to fix your proguard configuration. This whole problem is not really 
related to ksoap2-android but rather a a proguard item. On the ksoap2-android 
project we could post your proguard.cfg  you got it working. That might be a 
good contribution

It sounds like you've dealt with this before - following is my ProGuard config. 
 Can you point out what's wrong?

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontpreverify
-verbose

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keepclasseswithmembers,allowshrinking class * {
    native <methods>;
}
-keepclasseswithmembers class * {
    public <init>(android.content.Context,android.util.AttributeSet);
}
-keepclasseswithmembers class * {
    public <init>(android.content.Context,android.util.AttributeSet,int);
}
-keepclassmembers class * extends android.app.Activity {
    public void *(android.view.View);
}
-keepclassmembers enum  * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
-keep class * extends android.os.Parcelable {
    public static final android.os.Parcelable$Creator *;
}

Get rid of optimizations. Even the new SDK (r17) will have it disabled.. 

use --dontoptimize

Even after using -dontoptimize (along with -ignorewarnings), I still get the 
same XmlPullParserException.

Try a keep for all the classes that bomb. E.g. start with a wide sweep and then 
narrow things down.

I have ksoap working with proguard just fine so this is definitely a 
configuration error.

Could you post your (working) proguard config file, so I can see what I'm doing 
wrong here?

I got it resolved by adding the following lines into proguard.cfg:

-ignorewarnings
-keep class org.kobjects.** { *; }
-keep class org.ksoap2.** { *; }
-keep class org.kxml2.** { *; }
-keep class org.xmlpull.** { *; }

Cheers! ^_^

Thank @whuang1 so much, It took me hours to find out the reason why my project 
could not be built with proguard and with only 5 line of config rules. It 
finally run success.
