SOAP calls - No direct method error KXmlParser appears in moe-sdk-1.4.1/sdk/moe-core.dex


(Dave Kittredge) #1

I am trying to use ksoap2-android Jar to make a SOAP call to web services (in shared/common library).

I get an error: Pending exception java.lang.NoSuchMethodError: No direct method error(Ljava/lang/String;)V in class Lorg/kxml2/io/KXmlParser; or its super classes (declaration of ‘org.kxml2.io.KXmlParser’ appears in /Users/david/.moe/moe-sdk-1.4.1/sdk/moe-core.dex). kxml is used in ksoap.

I assumed ksoap was not supported by MOE, so I tried changing to org.apache.xmlbeans.impl.soap. I got errors trying to implement that, and cannot seem to make a soap call on the IOS side.

Is there a way to fix the soap error, or is there another SOAP library I can use that is compatible with MOE?

Thanks!


#2

Did you add all class from ksoap2 & kxml to proguard config?


(Dave Kittredge) #3

Thanks for the reply!
No, I had not added classes to proguard.
I am not familiar with proguard, but I created proguard.append.cfg, and put the following lines in it:
-keep class com.google.code.ksoap2.** { ; }
-keep enum com.google.code.ksoap2.
* { *; }

-keep class org.kxml2.io.KXmlParser.** { *; }
-keep enum org.kxml2.io.KXmlParser.** { *; }

Still same issue “Pending exception java.lang.NoSuchMethodError: No direct method error(Ljava/lang/String;)V in class Lorg/kxml2/io/KXmlParser”

Seems like the kxml2 you used is conflict with the one android runtime contains. Kxml2 is used internally by android (in libcore) and shoud be invisible to normal applications on normal android. But seems MOE somehow exported that.


(Dave Kittredge) #6

Thanks again for the reply. This is what I have found:
ksoap2 uses kxml version 2.2.4
Android JDK uses 2.3.0
I can’t figure out what version moe-core uses

This is what I tried:
iOS gradle added actionsAndOutlets section:
moe {
actionsAndOutlets {
excludeLibrary ‘org.kxml2’
}

in repositories section added:
maven { url ‘https://mvnrepository.com/artifact/net.sf.kxml/kxml2’ }

in dependencies section added the following:
implementation (‘com.google.code.ksoap2-android:ksoap2-android:3.6.2’, {
exclude group: ‘net.sourceforge.kxml’
})

implementation 'net.sf.kxml:kxml2:2.3.0'

I am still not having any luck, same errors.


#7

Interesting thing is on normal android if you try to use class org.kxml2.io.KXmlParser, you will also get this class from libcore instead of your onw version from gradle… I have no idea why google did this.

image
The BootClassLoader means this class is loaded from libcore instead of your own apk.


(Dave Kittredge) #8

Hmm, that does seem strange, but the Android part actually works in that I am able to compile and make SOAP calls to my server.

I am still confused by the messages. They seem to contradict themselves.


(Dave Kittredge) #9

From what I have seen on the internet, the No such method error is usually caused by different versions of the class /jar. I have tried many different things,

  • attempt to exclude MOE kxml version

  • attempt to load ksoap, excluding kxml.
    – also attempted to load kxml both 2.2.2 and 2.3.0 prior to ksoap.

  • tried adding the following to proguard.append.cfg:
    -dontwarn org.kobjects.**
    -dontwarn org.ksoap2.**
    -dontwarn org.kxml2.**
    -dontwarn org.xmlpull.v1.**

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

    -dontusemixedcaseclassnames
    -dontskipnonpubliclibraryclasses
    -dontoptimize
    -dontpreverify

Lastly, I tried downloading ksoap2, recompiling it with kxml 2.3.0, and copying Jars to a Libs folder (I tried with and without dependencies). I got errors (Error:(5, 21) Gradle: error: package org.kxml2.kdom does not exist) so I added implementation ‘net.sourceforge.kxml:kxml:2.2.0’ and now get Caused by: java.io.IOException: Duplicate zip entry [xmlpull-1.1.3.1.jar:org/xmlpull/v1/XmlPullParser.class]

i also tried ‘net.sourceforge.kxml:kxml:2.3.0’ and get Unexpected failure to resolve a method: void org.kxml2.io.KXmlParser.error(java.lang.String)

Is there anything I can do to get past this issue?


#10

One possible solution is adding the following code to your ios project’s build.gradle:

moeMainProGuard {
    doLast {
        def jar = getOutJar()
        def outputDir = file(jar.getAbsolutePath() + "_")
        copy{
            from(zipTree(jar)){
                exclude "org/kxml2/io/*"
                exclude "org/xmlpull/v1/**/*"
            }
            into outputDir
        }
        delete jar
        ant.jar(update: "true", index: "true", destfile: jar.getAbsolutePath()) {
            fileset(dir: outputDir)
        }
        delete outputDir
    }
}

It’s basically removing those duplicated classes from compiled outputs before it get merged with MOE runtime.

You don’t need to exclude anything from your dependencies with above hack. Keep in mind this is only a HACK so your project could compile and (possibly) run since those classes are not used on android anyway.


(Dave Kittredge) #11

One possible solution is adding the following code to your ios project’s build.gradle:

moeMainProGuard {
doLast {
def jar = getOutJar()
def outputDir = file(jar.getAbsolutePath() + “_”)
copy{
from(zipTree(jar)){
exclude “org/kxml2/io/"
exclude "org/xmlpull/v1/**/

}
into outputDir
}
delete jar
ant.jar(update: “true”, index: “true”, destfile: jar.getAbsolutePath()) {
fileset(dir: outputDir)
}
delete outputDir
}
}

Thank you so much!! This worked! I am able to get past the compile error and see the SOAP calls.
