Illegal Argument exception when adding external library to Android Studio

Question

I created four libraries in Eclipse that are interdependent. When I add the libraries to my Android project, I get the exception below. After going through a process of elimination, I found that one of the three libraries caused the exception.

I successfully use the four libraries in another Eclipse project, so I don't think there is anything wrong with them, the issue must be Android specific.

I also added the libraries to a new blank Android project, where they work just fine.

What are my options with the library in question? Do I remove the dependencies one by one or do I remove methods one by one?

I added the exception and my Gradle file below.

Gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId 'za.co.lot24media.password'
        minSdkVersion 16
        targetSdkVersion 28
        versionName '2'
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        signingConfig signingConfigs.config
        versionCode 2
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.config
        }
    }
    productFlavors {
    }
    buildToolsVersion '28.0.3'
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    packagingOptions {
        exclude '**/pom.xml'
    }
}

    implementation files('libs/commons-encrypt.jar')
    implementation files('libs/commons-files.jar')

}

Have to tried `cleaning the project and rebuilding` if that doesn't help then try `restart and invalidating the cache`. — Anmol, Jan 10 '19 at 05:22
The exception reoccurs after invalidating the cache and restarting. Cleaning the project succeeds, however, making the project after the clean fails. — Hendré, Jan 10 '19 at 05:33
`implementation fileTree(include: ['*.jar'], dir: 'libs')` as you have already added this line in your gradle so implementing `.jar` should not be any problem . — Anmol, Jan 10 '19 at 05:42
you have not enabled multidex, try adding `multiDexEnabled true` to defaultConfig in module level gradle. — karan, Jan 10 '19 at 07:30
I just added to multiDesEnabled entry, however, the issue persists. — Hendré, Jan 10 '19 at 09:16
What is your **java version** of Libs? if it's `JavaVersion.VERSION_1_7` or below then try removing your `sourceCompatibility JavaVersion.VERSION_1_8` from project gradle. it might be causing issue. — Jeel Vankhede, Jan 22 '19 at 05:11
@JeelVankhede All the libraries including the Android project are version 1.8. — Hendré, Jan 22 '19 at 07:38
have you tried changing the order of calling the libraries? and check for a line in last part of exception to see if this reaches your code. my other solution is removing them and adding them one by one to see which one is problematic — Pouya Danesh, Jan 22 '19 at 12:56

repositories {
    flatDir {
        dirs 'libs'
    }
}

try adding this to your app/gradle. and then do a rebuild.

If this is not working then you have to check your jar file's

read this for understanding your problem
read this for declaring default version for the dependency

Adding repositories flatDir to the app/gradle did not have any effect. The exception was thrown again. – Hendré Jan 10 '19 at 06:17
add jar one by one and check which jar is giving exception. @Hendré – Anmol Jan 10 '19 at 06:17
I did remove the jars one by one. When I remove the password-library.jar the exception went away. I rebuilt the password-library without any exception and added it back to the project. Then the same exception occurred. @Anmol – Hendré Jan 10 '19 at 06:45
https://stackoverflow.com/questions/35890257/android-errorexecution-failed-for-task-apptransformclasseswithdexforrelease/35899240#35899240 have you checked the version of android dependency your `password-library.jar` is using and your project is using i believe both project are fine if they run independently. BUT when u add a dependency of `password-library.jar` to your project then there is a dispute in the version of mutual dependencies of both the project's it `your project` and `password-library.jar` – Anmol Jan 10 '19 at 07:01

I recommend to search for the specific exception line (mostly the first one).

I think this link will help you solve the problem

I read the documentation at developer.android.com/studio/build/multidex. My libraries do not exceed 65,536 methods. I don't think multiDex is the issue. – Hendré Jan 10 '19 at 08:54
Sometimes your libraries use other libraries. It's worth a try. – Guy4444 Jan 10 '19 at 09:14
I just added to multiDesEnabled entry, however, the issue persists. – Hendré Jan 10 '19 at 09:15

You have not enabled multidex, Try adding below code to support multidexing and check

Modify your build.gradle:

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0"

         defaultConfig {
             minSdkVersion 14 //lower than 14 doesn't support multidex
             targetSdkVersion 22

             // Enabling multidex support.
             multiDexEnabled true
         }
}

dependencies {
    compile 'com.android.support:multidex:1.0.3'
}

your individual library might not be exceeding it but when you are combining them it might be. try changing and find out. – karan Jan 10 '19 at 08:53
