Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.hzy3774:AndroidUn7zip:1.6.0'
	}

	<dependency>
	    <groupId>com.github.hzy3774</groupId>
	    <artifactId>AndroidUn7zip</artifactId>
	    <version>1.6.0</version>
	</dependency>


                            
    libraryDependencies += "com.github.hzy3774" % "AndroidUn7zip" % "1.6.0"


                            
    :dependencies [[com.github.hzy3774/AndroidUn7zip "1.6.0"]]

Or just download the aar here
If you want to add some abi filters

android {
    ...
    defaultConfig {
        ...
        ndk {
            abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86'
         }
    }
}

Java API：

boolean extractFile(filePath, outPath, callback);
boolean extractAsset(assetManager, fileName, outPath, callback);
String getLzmaVersion();

ProGuard

If you are using ProGuard you might need to add the following options:

-keep class com.hzy.lib7z.** { *; }

Fetures

easily extract 7z from file
directly extract 7z from assets
unicode file names is available
add extract callbacks
