Android Studio build dex jar
Gradle配置
Build配置文件gradle.build中添加如下task
task clearJar(type: Delete) { delete 'build/outputs/mylib.jar' } task copyJar(type: Copy) { from('build/intermediates/bundles/release/') into('build/outputs/libs/') include('classes.jar') rename ('classes.jar', 'mylib.jar') } copyJar.dependsOn(clearJar, build)
此方法是直接从把gradle build生成的classes.jar拷贝到指定目录并且重命名,必须依赖build task。
修改dex jar的MANIFEST.MF文件
由于目前gradle的”com.android.application/library”不能和”java” plugin同时使用,所以我们可以使用其他方法来修改,本文中使用python的zipfile来处理。
自定义MANIFEST.MF文件
文件内容如下:
Manifest-Version: 1.0 Gradle-Version: 2.2.1 Created-By: 1.8.0_20-b26 (Oracle Corporation) Date: 2015-4-15 Author: Leo.Kang jar-version: 1.0.0
Python脚本
例如:新建一个python脚本,命名为updateJarManifest.py
#!/usr/bin/python import sys,zipfile,shutil,os def generate(): jar_file = "./mylib_temp.jar" target_jar = os.path.dirname(jar_file)+"/mylib.jar" shutil.copy(jar_file, target_jar) zipped = zipfile.ZipFile(target_jar, 'a', zipfile.ZIP_DEFLATED) content_file = "META-INF/MANIFEST.MF" mf_file = "./MANIFEST.MF" zipped.write(mf_file, content_file) zipped.close() return target_jar generate()
执行python的shell脚本(mac/linux)/批处理文件(win)
win
新建一个文件命名updateJar.bat文件内容为python updateJarManifest.py
mac/linux
新建一个文件命名为:updateJar.sh,
文件内容为:
#!/bin/bash #@author Leo.Kang # 2015-4-15 20:47 python ./ updateJarManifest.py
更新build.gradle 配置
task clearJar(type: Delete) { delete 'build/outputs/mylib.jar' } task copyJar(type: Copy) { from('build/intermediates/bundles/release/') into('build/outputs/libs/') include('classes.jar') rename ('classes.jar', 'mylib_temp.jar') } copyJar.dependsOn(clearJar, build) releaseJar.dependsOn(clearJar, build) task execPython(type:Exec) { //workingDir file('./') commandLine './updateJar.sh' } execPython.dependsOn(releaseJar)
