tinker patch集成实践

背景

截止17年3月11日,百川Hotfix1.x版本不支持安卓7.0系统(2.0版本跳票了2个月还没音讯),导致很多华为用户无法享受到热更新,因此放弃使用。
腾讯的热修复框架tinker涵盖系统广、可修复资源类型多等优势,我们选择其一站式的热修复平台tinker patch进行接入。

本次集成步骤,基于tinker Patch 1.1.4版本,使用android studio开发工具。官方的集成实践

准备工作

gradle文件

在工程根目录的build.gradle里添加tinkerPatch引用
classpath "com.tinkerpatch.sdk:tinkerpatch-gradle-plugin:1.1.4"

在项目的app工程目录下

  1. 添加gradle.properties文件,添加版本号作为全局变量
    version=4.0.4
  2. 添加tinkerpatch.gradle文件,封装了热修复所需要的函数,因为集成了andresguard资源混淆,因此文件略长
apply plugin: 'tinkerpatch-support'


//每次发热修复修改原包位置
def baseInfo = "app-4.0.6-0310-18-00-37"

def bakPath = file("${buildDir}/bakApk/")
def variantName = "release"

/**
 * 对于插件各参数的详细解析请参考
 * http://tinkerpatch.com/Docs/SDK
 */
tinkerpatchSupport {

    appKey = "你的tinkerPatch key"
    /** 可以在debug的时候关闭 tinkerPatch, isRelease() 可以判断BuildType是否为Release **/
    tinkerEnable = isRelease()
    reflectApplication = true
    autoBackupApkPath = "${bakPath}"

    /** 注意: 若发布新的全量包, appVersion一定要更新 **/
    appVersion = version

    def pathPrefix = "${bakPath}/${baseInfo}/${variantName}/"
    def name = "${project.name}-${variantName}"

    baseApkFile = "${pathPrefix}/${name}.apk"
    baseProguardMappingFile = "${pathPrefix}/${name}-mapping.txt"
    baseResourceRFile = "${pathPrefix}/${name}-R.txt"

    /**
     *  若有编译多flavors需求, 可以参照: https://github.com/TinkerPatch/tinkerpatch-flavors-sample
     *  注意: 除非你不同的flavor代码是不一样的,不然建议采用zip comment或者文件方式生成渠道信息(相关工具:walle 或者 packer-ng)
     **/
}

/**
 * 用于用户在代码中判断tinkerPatch是否被使能
 */
android {
    defaultConfig {
        buildConfigField "boolean", "TINKER_ENABLE", "${tinkerpatchSupport.tinkerEnable}"
    }
}

/**
 * 一般来说,我们无需对下面的参数做任何的修改
 * 对于各参数的详细介绍请参考:
 * https://github.com/Tencent/tinker/wiki/Tinker-%E6%8E%A5%E5%85%A5%E6%8C%87%E5%8D%97

        resguardTask.doFirst {
            def resMapping = "${bakPath}/${baseInfo}/${taskName}/${project.name}-${taskName}-resource_mapping.txt"
            File mapping = new File(resMapping)
            if (mapping.exists()) {
                println("change resguardTask mapping file to ${resMapping}")
                project.extensions.andResGuard.mappingFile = file(resMapping)

        }
        tinkerPatchTask.doFirst {

            println("change tinkerPatchTask baseApk to ${destFilePrefix}-resuguard.apk")
            project.extensions.tinkerPatch.oldApk = "${bakPath}/${baseInfo}/${variantName}/${destFilePrefix}-resuguard.apk"

        }
        tinkerPatchTask.dependsOn resguardTask

        resguardTask.doLast {
            String buildType = variant.buildType.name.toLowerCase()

            if (!name.equalsIgnoreCase(buildType) && name.endsWith(buildType)) {
                name = name - buildType + "-${buildType}"
            }

            String mAppVersion = project.extensions.tinkerpatchSupport.appVersion

            String destPath = "${bakPath}/${project.name}-${mAppVersion}-${date}/${name}/"

            copy {
                from "${buildDir}/outputs/apk/AndResGuard_${project.getName()}-${taskName}/${project.getName()}-${taskName}_signed_7zip_aligned.apk"
                into file("${destPath}/")
                rename { String fileName ->
                    fileName.replace("${project.getName()}-${taskName}_signed_7zip_aligned.apk", "${destFilePrefix}-resuguard.apk")
                }

                from "${buildDir}/outputs/apk/AndResGuard_${project.getName()}-${taskName}/resource_mapping_${project.getName()}-${taskName}.txt"
                into file("${destPath}/")
                rename { String fileName ->
                    fileName.replace("resource_mapping_${project.getName()}-${taskName}.txt", "${destFilePrefix}-resource_mapping.txt")
                }
            }
        }
    }

}

  1. 打开app的build.gradle文件,添加第二步gradle文件引用
    apply from: 'tinkerpatch.gradle'
    依赖关系添加tinker
    provided("com.tencent.tinker:tinker-android-anno:1.7.7")
    compile("com.tinkerpatch.sdk:tinkerpatch-android-sdk:1.1.4")

代码集成

在项目的application文件,添加下述代码,然后在oncreate()方法,调用initTinker()即可

private ApplicationLike tinkerApplicationLike;

private void initTinker() {
        // 我们可以从这里获得Tinker加载过程的信息
        if (BuildConfig.TINKER_ENABLE) {
            tinkerApplicationLike = TinkerPatchApplicationLike.getTinkerPatchApplicationLike();

            // 初始化TinkerPatch SDK
            TinkerPatch.init(tinkerApplicationLike)
                    .reflectPatchLibrary()
                    .setPatchRollbackOnScreenOff(true)
                    .setPatchRestartOnSrceenOff(true);

            TinkerPatch.with().fetchPatchUpdate(true);
        }
    }

上述步骤可以在官方集成demo中查看,本文多了andresguard步骤,因此会略有出入。
至此tinker已经集成完毕了,接下来是打热修复patch步骤

热修复

  1. 在tinkerPatch.gradle文件里,修改baseInfo路径,其指定了老apk包的路径,可以在apk输出目录的bakApk目录下复制文件夹名即可
  2. 所有build varianties切换成release模式,找到gradle任务的tinker patch release任务双击运行
    运行tinker创建热修复包.png
  3. 在apk输出目录下,打开tinkerPatch目录,找到名叫patch_signed_7zip.apk的补丁包,上传到tinkerPatch(选择开发预览模式)。
  4. 本地验证,下载tinkerPatch的debug tools并开启,重启app开始检查热更新,查看log输出,如果提示等待重启,则锁屏,解锁,即可看到热修复生效。
  5. 本地验证通过之后,切换补丁发布模式为全量发布

后记

  1. 每次发版,修改版本号均要在我们添加的gradle.properties里修改
  2. 使用极光推送的自定义消息体,通知客户端调用TinkerPatch.with().fetchPatchUpdate(true);访问热修复接口,可以大大提高热修复的及时性,内容里面使用hotfix_1.0.0,客户端通过版本号匹配与否来决定是否需要访问热修复。因为tinker patch的费用与更新请求访问量挂钩。
  3. 遇到线上包需要发1个以上补丁时,每次补丁需要涵盖之前所有修复的内容,也就是说,每次补丁的基准包都是线上包的代码。
    tinkerPatch自动会请求最新的补丁。
