本文说明
面试的时候经常问我有没有用过热修复?用谁的?能说下原理吗?当时我回答得不好,毕竟以前的项目都没有用,又不敢装逼,mmp,但是基本流程还是知道的,所以我们来初探下Tinker 这个热修复,如果我是Andriod studio 2.3的话,我还不怎么想写这个文章,毕竟太多了,没有什么坑了,但是我用的是Andriod studio 3.0 尴尬了 他有很多新特色配置,我不知道呢!而且我都没有玩过他,踩了坑,花了3个小时 摸索,百度,等,终于搞定了。下一篇写一下热修复下的多渠道打包和配置,希望给有碰到朋友一些帮助吧。
简介
现在热修复的技术基本上有阿里的AndFix、QZone的方案、美团提出的思想方案以及腾讯的Tinker等。
其中AndFix可能接入是最简单的一个(和Tinker命令行接入方式差不多),不过兼容性还是是有一定的问题的;QZone方案对性能会有一定的影响,且在Art模式下出现内存错乱的问题(其实这个问题我之前并不清楚,主要是tinker在MDCC上指出的);美团提出的思想方案主要是基于Instant Run的原理,目前尚未开源,不过这个方案我还是蛮喜欢的,主要是兼容性好。
选择开源方案,tinker目前是最佳的选择,tinker的介绍有这么一句:
Tinker已运行在微信的数亿Android设备上,那么为什么你不使用Tinker呢?
比较
官方说明
1. Tinker不支持修改AndroidManifest.xml,Tinker不支持新增四大组件(1.9.0支持新增非export的Activity);
2. 由于Google Play的开发者条款限制,不建议在GP渠道动态更新代码;
在Android N上,补丁对应用启动时间有轻微的影响;
3.不支持部分三星android-21机型,加载补丁时会主动抛出”TinkerRuntimeException:checkDexInstall failed”;
4. 对于资源替换,不支持修改remoteView。例如transition动画,notification icon以及桌面图标。
最大的变化就是app\build.gradle 文件了
官网文件地址 我们直接看他的修改记录的对比文档 这样我们更容易清楚我们改变了什么,该怎么去配置。
对比文件地址
关键对比代码和出错
出错点一
首先 我们按常规思路去引入配置3.0方式 一般 如下
//可选,用于生成application类
implementation("com.tencent.tinker:tinker-android-lib:${TINKER_VERSION}") { changing = true }
//tinker的核心库
annotationProcessor("com.tencent.tinker:tinker-android-anno:${TINKER_VERSION}") { changing = true }
虽然成功了,没有报错,但是 我们在代码中执行Thinker 的方法时却找不到了
如图
这说明我们的包没有正确的倒进来,我们得添加下面这行代码才行
其实这个compileOnly就是我们的provided 在3.0中被代替了
compileOnly("com.tencent.tinker:tinker-android-anno:${TINKER_VERSION}") { changing = true }
这样我们就没有这样的问题了。
完整配置
//其实就是一个判断 判断是否com.android.tools.build:gradle:3.0.0'
//是的话就按3.0去配置
//我们的TINKER_VERSION是配置在gradle.properties 中的
if (is_gradle_3()) {
implementation fileTree(dir: 'libs', include: ['*.jar'])
testImplementation 'junit:junit:4.12'
implementation "com.android.support:appcompat-v7:23.1.1"
implementation("com.tencent.tinker:tinker-android-lib:${TINKER_VERSION}") { changing = true }
annotationProcessor("com.tencent.tinker:tinker-android-anno:${TINKER_VERSION}") { changing = true }
compileOnly("com.tencent.tinker:tinker-android-anno:${TINKER_VERSION}") { changing = true }
implementation "com.android.support:multidex:1.0.1"
//use to test multiDex
// implementation group: 'com.google.guava', name: 'guava', version: '19.0'
// implementation "org.scala-lang:scala-library:2.11.7"
//use for local maven test
// implementation("com.tencent.tinker:tinker-android-loader:${TINKER_VERSION}") { changing = true }
// implementation("com.tencent.tinker:aosp-dexutils:${TINKER_VERSION}") { changing = true }
// implementation("com.tencent.tinker:bsdiff-util:${TINKER_VERSION}") { changing = true }
// implementation("com.tencent.tinker:tinker-ziputils:${TINKER_VERSION}") { changing = true }
// implementation("com.tencent.tinker:tinker-commons:${TINKER_VERSION}") { changing = true }
} else {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile "com.android.support:appcompat-v7:23.1.1"
compile("com.tencent.tinker:tinker-android-lib:${TINKER_VERSION}") { changing = true }
provided("com.tencent.tinker:tinker-android-anno:${TINKER_VERSION}") { changing = true }
compile "com.android.support:multidex:1.0.1"
出错点二
我们在配置中有这么一块代码片他是用于自定义我们的apk名称和mapping名称的
/**
* bak apk and mapping
*/
android.applicationVariants.all { variant ->
/**
* task type, you want to bak
*/
def taskName = variant.name
def date = new Date().format("MMdd-HH-mm-ss")
tasks.all {
if ("assemble${taskName.capitalize()}".equalsIgnoreCase(it.name)) {
it.doLast {
copy {
def fileNamePrefix = "${project.name}-${variant.baseName}"
def newFileNamePrefix = hasFlavors ? "${fileNamePrefix}" : "${fileNamePrefix}-${date}"
def destPath = hasFlavors ? file("${bakPath}/${project.name}-${date}/${variant.flavorName}") : bakPath
/**
这里报错了 无法识别outputFile
**/
from variant.outputs.outputFile
into destPath
rename { String fileName ->
fileName.replace("${fileNamePrefix}.apk", "${newFileNamePrefix}.apk")
}
from "${buildDir}/outputs/mapping/${variant.dirName}/mapping.txt"
into destPath
rename { String fileName ->
fileName.replace("mapping.txt", "${newFileNamePrefix}-mapping.txt")
}
from "${buildDir}/intermediates/symbols/${variant.dirName}/R.txt"
into destPath
rename { String fileName ->
fileName.replace("R.txt", "${newFileNamePrefix}-R.txt")
}
}
}
}
}
}
但是我们3.0中却报错了 outputFile不能识别了
我们执行生成基础包apk时
解决办法
修改代码
from variant.outputs.outputFile
为
from variant.outputs.first().outputFile
这样就没有问题了

基础包(执行打包操作后)app/build.gradle
我们生成了bakApk 文件
与未打包的区别 我们把对应的参数修改填进去
//老版本的文件所在的位置,大家也可以动态配置,不用每次都在这里修改
ext {
//for some reason, you may want to ignore tinkerBuild, such as instant run debug build?
tinkerEnabled = true
//for normal build
//old apk file to build patch apk
tinkerOldApkPath = "${bakPath}/app-release-1201-23-58-59.apk"
//proguard mapping file to build patch apk
tinkerApplyMappingPath = "${bakPath}/app-release-1201-23-58-59-mapping.txt"
//resource R.txt to build patch apk, must input if there is resource changed
tinkerApplyResourcePath = "${bakPath}/app-release-1201-23-58-59-R.txt"
//only use for build all flavor, if not, just ignore this field
//这里可以不填 他这里是分出一个单独的文件夹
//tinkerBuildFlavorDirectory = "${bakPath}/app-1018-17-32-47"
tinkerBuildFlavorDirectory = "${bakPath}/"
}
好的到这里我算是成功一半了。
步骤一
我们先写些代码
配置我们AndroidManifest.xml

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

配置MainActivity.class
package com.achers.tinkermain;

import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;

import java.io.File;
public class MainActivity extends AppCompatActivity {
private String mPath;
@SuppressLint("WrongViewCast")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mPath = getExternalCacheDir().getAbsolutePath() + File.separatorChar;
}
/**
* 加载Tinker补丁
*
* @param view
*/
public void Fix(View view) {
File patchFile = new File(mPath, "patch_signed.apk");
if (patchFile.exists()) {
TinkerManager.addPatch(patchFile.getAbsolutePath());
Toast.makeText(this, "File Exists,Please wait a moment ", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "File No Exists", Toast.LENGTH_SHORT).show();
}
}
}
activity_main.xml文件

好的 我们生成bakApk 包
我们就安装到手机 测试下 安装包是否有问题 按找我的来 没问题的,有问题 我请你吃鸡。
在之前我们要先更新下我们的代码,热修复嘛,你代码都没有改变,还修个毛线,不如吃鸡。

我们执行生成修复包的命令 生成补丁
执行成功会有文件生成
app\build\outputs\apk\tinkerPatch
这样代表我们的patch_signed.apk 成功生成了
这样我们需要将文件patch_signed.apk 放到 缓存目录下,修复补丁后的程序
通过Context.getExternalFilesDir()方法可以获取到 SDCard/Android/data/你的应用的包名/files/ 目录,一般放一些长时间保存的数据
通过Context.getExternalCacheDir()方法可以获取到 SDCard/Android/data/你的应用包名/cache/目录,一般存放临时缓存数据
由于没有手机录屏工具转gif 失败 所以我想传gif的 找了几个工具都不行了 真的尴尬。不过我还可以上点图片的。
最后把我的demo 上传 大家可以尝试去配置,相信你可以的。用过Thinker的更不用说了。
demo下载地址
1. 网络情况不佳时,tinker插件所依赖的库或者插件缺失(如 com.tencent.mm:SevenZip 缺失)
1.1 原因:下载地址是https开头,导致下载不下来
1.2 解决办法:找到C盘用户目录下.gradle目录下的cache目录(形如 C:\Users\hasee.gradle\caches)
删除该文件夹下所有文件以及文件夹然后将 根目录(Project:)build.gradle中把
把
jcenter()
更改为
jcenter(){ url 'http://jcenter.bintray.com/' }
再重新编译。(相当于再次重新下载依赖)
2.Error:Execution failed for task ‘:app:transformClassesWithJarMergingForDebug’. BSDiff$1.class
解决办法: clean project
3.Error:(9, 0) Your project path contains non-ASCII characters编译失败
原因:工程目录处于中文路径下
解决办法:不处于中文路径下就好了
4.加载补丁时补丁加载失败
补丁加载失败的原因很多,具体原因可以在logcat中查看,但是需要确保logcat的设置如下,否则tinker合成补丁日志输出获取不到
解决办法:注意不要搞混 tinkerPatchDebug gradle任务 和 tinkerPatchReleas gradle任务 对应生成的
patch_signed_7zip,debug签名就用 tinkerPatchDebug gradle任务 生成的 patch_signed_7zip
