Error while using Github library in Java in Android Studio

Question

I want to create a Speaker Recognition Android app using android studio.

I came accross https://github.com/amaurycrickx/recognito Library in java. But I am having difficulty in implementing it in Android.

First, I saved the recognito folder by copying it in libs folder (creating it manually) in my main directory of my android app.

Then, in settings.gradle file -- include ':recognito'

build.gradle app file --     compile project(':recognito')

After sync. getting the error -

Error:Project :app declares a dependency from configuration 'compile' to configuration 'default' which is not declared in the descriptor for project :recognito.

I researched, Gradle error: configuration declares dependency which is not declared It says that since build.gradle file doesn`t exists for the Recognito project. But how will it? Cos it contains only java files.

Please help ..

Build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '25.0.0'

    defaultConfig {
        applicationId "com.urvi.android.abc"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:support-v4:23.4.0'
    compile project(':recognito')

}

settings.gradle

include ':app'
include ':recognito'

and the folder Recognito I copied has https://github.com/amaurycrickx/recognito/tree/master/recognito files. I did not copy from the initial path

Answer 1

It seems that this library has not been made to be used for Android app but Java application. It uses parts of the Java API not available for Android (like javax.sound.sampled.*). Plus I'd not recommend to use any library not being updated in the last 3 years.

The way you try to add the library it needs to have gradle build-files. I see 2 ways to solve the problem:

• create a jar from the library and include it this way
• use a service like jitpack to include the library

For generating the jar: * clone the repo * cd recognito * mvn package

then you get:
