androidun7zip's Introduction

AndroidUn7zip(安卓7zip解压)

A simple library with lzma sdk for 7z extraction.(使用LZMA SDK解压7z压缩包)

Introduction

官方网站：https://www.7-zip.org/sdk.html
7z is the new archive format, providing high compression ratio.

Begin To Use

Add gradle dependencie:

repositories {
    maven { url 'https://jitpack.io' }
}

dependencies {
   implementation 'com.github.hzy3774:AndroidP7zip:v1.7.2'
}

dependencies {
    implementation 'com.hzy:un7zip:+'
}

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

Screenshot

Thanks To

danhantao offered X86 compiled(修复了X86编译问题)
ransj offered the way to extract 7z file from assets directly(添加了直接从assets解压的功能)

[7z.ErrorCode:16][7z.ErrorMsg:Stream Extract Error]

你好能提供armeabi架构吗

ndk编译时error: 'AAsset_getLength64' was not declared in this scope

././un7zip/7zAssetFile.cpp: In function 'WRes InAssetFile_Open(AAssetManager*, CSzAssetFile*, const char*)':

大哥，你的jar包是不是少一个呀。

大哥，用c语言进行解压文件是不是比用java解压的效率快很多？

你的demo只提供解压功能，不提供压缩，或者其他的密码解压之类的吗？可否提供一些相关的资料。

What is the difference between AndroidP7zip and AndroidUn7zip??

Extract From File not worked

Hi, thank you for your solution.
i have a problem.
When i select 7z file from SD card and click on "StartExtractFile" it always returns false.

8.0以下启动报错，可以testin跑一下

Password protected files

How do I set for decompressor the password for protected files?

Android10 Input File Open Error

机型：华为P20
系统：Android10
复现步骤：
1、把assets目录下的TestAsset.7z拷贝到SDcard根目录
2、点击Choose File按钮，选择SDcard根目录的TestAsset.7z
3、点击Extract File按钮

Crash how to fix.

可以考虑增加回调接口，允许使用 ReLinker 来加载 .so 文件吗？

出错log：

只在个别机型上出现，目前看到的是 API 19, 占得比例也较小。

mmkv 的建议方案：

在某些 Android 设备上（API level 19）遇到java.lang.UnsatisfiedLinkError。这是怎么回事，我应该采取什么措施？
API level 19 的 Android 设备在安装、更新 APK 时，可能会遗漏 libmmkv.so。针对这个问题，已有专门的开源库 ReLinker 解决。

解压.PNG文件出错

解压txt文件OK，为什么一解压.png文件就报 errorCode 16 message Stream Extract Error

大哥能不能提供一个带密码解压的功能.

When the device memory is not enough, it will cause overflow

When decompressing, when the size of a single file exceeds the remaining memory, it will directly fail

Support Unrar5

Hello admin @hzy3774
Please support UnRar5.
Thank you very much

可否推到maven上方便引用

很感谢这个project，但因为用了desprateNDK 我没法直接集成
希望能丢到maven上或者jitpack.io这种地方
谢谢

可以提供全平台的.so吗？

app crash when start extract in release mode

app crash when start extract in release mode ,but debug is working any help to solve the issue ..thank you

提取压缩包中单个文件

想压缩so 所占apk体积整体打包so文件40多m 包含所有用到的so文件想用时单独提取某一个

Cannot extract file that in the Download dir. And the 1.6.0 demo apk cannot parse Download Dir Uri to file path.

I download a 7z file to the sdcard dir and try to extract it, but show me "SZ_ERROR_ARCHIVE" when I pass the file path (/storage/emulated/0/xxxxx/xxxx.7z) but extract as assets successfully. I download the 1.6.0 demo apk and try to extract too, I find It always tell me the path file is null and the code cannot parse file in download dir to file path.
I guess the reason why extract failed is the srcPath parse failed on 1.7.1. Can you check it? @hzy3774

不能压缩吗

Migrate from JCenter to another maven repository

Are you using JCenter to host the artifact?

Because if I remove jcenter() from repositories gradle block, the library won't be imported:

repositories {
        jcenter() //if I remove this
}

dependencies {
        implementation 'com.hzy:un7zip:1.7.1'
}

JCenter is at end of life. Please migrate if needed.

Extract from stream on the fly

Hello. Just a suggestion to make possible unzipping while, for example, downloading file. If I have 500mb zipped file on the server and need to place it on the phone in unzipped state (2 gb unzipped file), I wouldn't want to download it first then unzip. It will require 2.5 gb of free storage instead of 2gb.

It would be cool to also unzip file to stream. To make it possible to directly send file to the server or to store it in RAM, without placing it in phone ROM.
