Android studio build failed #128

felix2ch · 2018-06-13T11:02:32Z

I create a project using jSerialComm in Android studio by gradle.

But build failed with error:
Illegal class file: Class module-info is missing a super type.

Same here, any ideas / solution?

This happens using android studio, adding a java module, adding a dependency jSerialComm:
implementation 'com.fazecast:jSerialComm:2.0.2'

Downgrading to 1.3.11 works.

It appears that Android Studio hasn't figured out how to ignore newer Java 9+ features, even though they aren't required for this library to work. Until that is resolved, you can use the following as a workaround in your Android gradle.build file:

If it already includes a 'configurations' section, add the word 'repackage' to its list of arguments. If it does not include a 'configurations' section, add the following code to gradle.build somewhere above the 'dependencies' section:

configurations {
    repackage
}

In the 'dependencies' section, remove any lines you currently have referencing jSerialComm, and replace them with:

repackage 'com.googlecode.jarjar:jarjar:1.3'
repackage 'com.fazecast:jSerialComm:2.+'

such that your 'dependencies' section has a form similar to:

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0-beta01'
    ..... [other lines]
    repackage 'com.googlecode.jarjar:jarjar:1.3'
    repackage 'com.fazecast:jSerialComm:2.+'
    ..... [other lines]
}

Finally, add the following code to the very bottom of your gradle.build file:

task repackageJavaModuleJars() {
    project.ant {
        taskdef name: 'jarjar', classname: 'com.tonicsystems.jarjar.JarJarTask', classpath: configurations.repackage.asPath
        jarjar(jarfile: 'libs/repackagedLibs.jar', filesetmanifest: 'merge') {
            configurations.repackage.each {
                if (!it.getName().find('jarjar-')) {
                    zipfileset(src: it, excludes: 'module-info.class')
                }
            }
        }
    }
}

Save and rebuild your project, and it should automatically remove any Java 9 features from the library such that it can be successfully built and used in your Android application.

Did not work for me?
Any suggestions?

hedgecrw · 2018-09-24T17:21:18Z

Simply delete the 'module-info.class' file from the jSerialComm JAR file (opened using a zip file editor). This is an Android Studio issue.

ChadWagner · 2018-09-24T17:28:37Z

Getting closer....

Program type already present: com.fazecast.jSerialComm.SerialPort$SerialPortEventListener$1
Message{kind=ERROR, text=Program type already present: com.fazecast.jSerialComm.SerialPort$SerialPortEventListener$1, sources=[Unknown source file], tool name=Optional.of(D8)}

Any suggestions?

ChadWagner · 2018-09-24T18:54:45Z

I removed the jar and so files I had downloaded and added
compile 'com.fazecast:jSerialComm:[2.0.0,3.0.0)'
to the end of my dependencies in the build.gradle files and added
import com.fazecast.jSerialComm.*;
to my MainActivity.java
It now builds!!

But it crashes... Do I have to install the .so file somewhere an my Android Oreo 8.1?

Debugging I see the following:
libraryPath="Android/arm64-v8a"
fileName=libjSerialComm.so

It seems to lock on the following line:
InputStream fileContents = SerialPort.class.getResourceAsStream("/" + libraryPath + "/" + fileName);

I think the .so files are not being used correctly?

Please help???

Should the versions be arm64-v8a?

ChadWagner · 2018-09-25T07:30:48Z

My .apk file includes OSX and Windows but not Android. What have I done wrong?

I cant open port in android studio

Any ideas what im doing wrong?

I encountered the same problem, and I finally found a workaround solution.

First, before you try repackaging, please make sure you install NDK tools because jSerialComm contains native codes.

Second, after adding the repackaging Gradle script into your project, you need to satisfy linking by adding shared libraries, ".so" files, into JNI source directories.

Sample Gradle task:

// copy .so files from repackagedLibs.jar into jniLibs
task copySharedLibraries(type: Copy) {
    from(zipTree('libs/repackagedLibs.jar')) {
        include 'Android/*/libjSerialComm.so'
    }
    into('src/main/jniLibs/')
    eachFile {item ->
         item.path = item.path.replaceAll(/Android\/(.*?)\/libjSerialComm.so/, '$1/libjSerialComm.so')
    }
    doLast {
        delete 'src/main/jniLibs/Android/'
    }
}

That is all for my workaround.
If you have any better ideas, please tell me.
