tinker热修复gradle接入

本篇文章已授权微信公众号 guolin_blog （郭霖）独家发布

2021-04-29更新，最近在复习热修复，发现我的老代码不行了，所以把这篇文章更新一下
本篇是gradle接入
tinker的github网址为tinker
我使用的最新版本为TINKER_VERSION=1.9.14.12
下面开始更新新版的代码

在peoject的build中配置如下


buildscript {repositories {mavenLocal()jcenter()google()}dependencies {classpath 'com.android.tools.build:gradle:3.5.3'classpath("com.tencent.tinker:tinker-patch-gradle-plugin:${TINKER_VERSION}") {changing = TINKER_VERSION?.endsWith("-SNAPSHOT")exclude group: 'com.android.tools.build', module: 'gradle'}}configurations.all {it.resolutionStrategy.cacheDynamicVersionsFor(5, 'minutes')it.resolutionStrategy.cacheChangingModulesFor(0, 'seconds')}
}allprojects {repositories {mavenLocal()jcenter()google()}
}

TINKER_VERSION需要在gradle.properties中进行配置我的gradle.properties文件内容为

TINKER_VERSION=1.9.14.12
android.useAndroidX=true
android.enableJetifier=true
android.enableR8 = false

我在用老的项目测试最新版本的tinker的时候，发现R8打补丁包的时候总是报错，所以我把R8静止掉了

接下来是配置app的build，官方文档推荐我们使用他们demo里面的配置
build.gradle
于是我全部copy了过来，不过里面的几个地方还是需要修改的
首先先贴上全部的
我会在里面写上注释

}

主要修改了下面几个地方

def getTinkerIdValue() {hasProperty("TINKER_ID") ? TINKER_ID : gitSha()
}

官方文档默认是将git提交的记录作为think_id记录下来，这里我不需要，所以我改成下图

def getTinkerIdValue() {return "1.0"
}

接下来修改自己的签名文件,我这里配置的文件路径在APP的目录下面账号密码如下，是我在写robustdemo的时候生成的

   //配置自己的签名文件，签名文件的生成和导入可以去百度，本篇不讲解signingConfigs {debug {keyAlias "key0"keyPassword "123456"storeFile file('robustsign2')storePassword "123456"}release {keyAlias "key0"keyPassword "123456"storeFile file('robustsign2')storePassword "123456"}}

   buildTypes {release {minifyEnabled truesigningConfig signingConfigs.releaseproguardFiles getDefaultProguardFile('proguard-android.txt'), project.file('proguard-rules.pro')}debug {debuggable trueminifyEnabled falsesigningConfig signingConfigs.debug}}

配置完上面之后，build就配置好了，接下来配置application
先上代码

package com.anlaiye.swt.gradletest;import android.annotation.TargetApi;
import android.app.Application;
import android.content.Context;
import android.content.Intent;
import android.os.Build;import androidx.multidex.MultiDex;import com.tencent.tinker.anno.DefaultLifeCycle;
import com.tencent.tinker.entry.ApplicationLike;
import com.tencent.tinker.lib.tinker.TinkerInstaller;
import com.tencent.tinker.loader.shareutil.ShareConstants;@DefaultLifeCycle(application = "tinker.sample.android.app.SampleApplication",flags = ShareConstants.TINKER_ENABLE_ALL,loadVerifyFlag = false)
public class SimpleTinkerInApplicationLike extends ApplicationLike {public SimpleTinkerInApplicationLike(Application application, int tinkerFlags, boolean tinkerLoadVerifyFlag, long applicationStartElapsedTime, long applicationStartMillisTime, Intent tinkerResultIntent) {super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime, applicationStartMillisTime, tinkerResultIntent);}@Overridepublic void onBaseContextAttached(Context base) {super.onBaseContextAttached(base);MultiDex.install(base);TinkerInstaller.install(this);}@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)public void registerActivityLifecycleCallbacks(Application.ActivityLifecycleCallbacks callback) {getApplication().registerActivityLifecycleCallbacks(callback);}
}

这个application官网有提供的，也可以copy我的，SimpleTinkerInApplicationLike 并不是一个application真正的application是@DefaultLifeCycle里面的tinker.sample.android.app.SampleApplication
所以在androidmanifest中配置application的name

   android:name="tinker.sample.android.app.SampleApplication"

打开SampleApplication可以看到其实会定位到我们的application

public class SampleApplication extends TinkerApplication {public SampleApplication() {super(15, "com.anlaiye.swt.gradletest.SimpleTinkerInApplicationLike", "com.tencent.tinker.loader.TinkerLoader", false, false);}}

同时配置读取sd卡的权限

接下来测试

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/activity_main"android:layout_width="match_parent"android:layout_height="match_parent"android:paddingBottom="@dimen/activity_vertical_margin"android:paddingLeft="@dimen/activity_horizontal_margin"android:paddingRight="@dimen/activity_horizontal_margin"android:paddingTop="@dimen/activity_vertical_margin"tools:context="com.anlaiye.swt.gradletest.MainActivity"><TextViewandroid:id="@+id/tv"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="22222"/><Buttonandroid:layout_below="@+id/tv"android:onClick="loadPath"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="更新"/>
</RelativeLayout>

第一次我设置textview的值是22222
然后设置按钮调用onclick

package com.anlaiye.swt.gradletest;import android.Manifest;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.view.View;
import android.widget.Toast;import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;import com.tencent.tinker.lib.tinker.TinkerInstaller;import java.io.File;public class MainActivity extends AppCompatActivity {public static final int MY_PERMISSIONS_REQUEST_READ_CONTACTS = 1;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);if (!hasRequiredPermissions()) {ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 0);}}private boolean hasRequiredPermissions() {if (Build.VERSION.SDK_INT >= 16) {final int res = ContextCompat.checkSelfPermission(this.getApplicationContext(), Manifest.permission.READ_EXTERNAL_STORAGE);return res == PackageManager.PERMISSION_GRANTED;} else {// When SDK_INT is below 16, READ_EXTERNAL_STORAGE will also be granted if WRITE_EXTERNAL_STORAGE is granted.final int res = ContextCompat.checkSelfPermission(this.getApplicationContext(), Manifest.permission.WRITE_EXTERNAL_STORAGE);return res == PackageManager.PERMISSION_GRANTED;}}//加载补丁public void loadPath(View view) {requestPermi();}public void loadApk() {String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/app-release-patch_signed_7zip.apk";File file = new File(path);if (file.exists()) {Toast.makeText(this, "补丁已经存在", Toast.LENGTH_SHORT).show();TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(), path);Log.d("swy", path);} else {Toast.makeText(this, "补丁已经不存在", Toast.LENGTH_SHORT).show();Log.d("swy", path);}}private void requestPermi() {if (ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {// Should we show an explanation?if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,Manifest.permission.READ_EXTERNAL_STORAGE)) {// Show an expanation to the user *asynchronously* -- don't block// this thread waiting for the user's response! After the user// sees the explanation, try again to request the permission.} else {// No explanation needed, we can request the permission.ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},MY_PERMISSIONS_REQUEST_READ_CONTACTS);Log.d("swt", "requestPermi: ");// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an// app-defined int constant. The callback method gets the// result of the request.}} else {//有权限直接加载apkloadApk();}}@Overridepublic void onRequestPermissionsResult(int requestCode,String permissions[], int[] grantResults) {switch (requestCode) {case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {// If request is cancelled, the result arrays are empty.if (grantResults.length > 0&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {// permission was granted, yay! Do the// contacts-related task you need to do.//权限申请成功加载apkloadApk();Log.d("swt", "permissionsuss: ");} else {// permission denied, boo! Disable the// functionality that depends on this permission.}return;}}}
}

我是直接运行的release包把这个修改了

然后我运行APP
会生成如下的目录结构

同时界面效果

接下来打开app的build找到ext模块
做如下修改将里面的名字和我们生成apk的名字对应


//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 apktinkerOldApkPath = "${bakPath}/app-release-0429-16-28-46.apk"//proguard mapping file to build patch apktinkerApplyMappingPath = "${bakPath}/app-release-0429-16-28-46-mapping.txt"//resource R.txt to build patch apk, must input if there is resource changedtinkerApplyResourcePath = "${bakPath}/app-release-0429-16-28-46-R.txt"//only use for build all flavor, if not, just ignore this fieldtinkerBuildFlavorDirectory = "${bakPath}/app-1018-17-32-47"
}

接下来修改mainactivity的xml文件把textview改成33333，用来和第一次作区别

注意接下来的这个操作是避免这个错误

app\build\intermediates\tinker_intermediates\values_backup

接下来把bakapk整个文件夹移出来,移到app的目录下面这样

然后再clean一下,在到app的目录下面生成build文件夹
把bakapk文件夹移进去

然后点击tinker的path命令生成渠道包

生成目录如下

注意箭头所指的文件
我们在onclick中执行的文件名就是这个，这个文件就是我们需要的最终的文件
然后将这个文件导入SD卡的最外层目录

 adb push /Users/yanzhe/AndroidStudioProjects/TinkerGradleDemo/app/build/outputs/apk/tinkerPatch/release/app-release-patch_signed_7zip.apk /sdcard

导入成功后
点击更新按钮

textview由22222变成33333
但是应用会闪退一下
好像是和这个issue有关
issue

本篇只是简单的演示了整个流程，整理了一下容易踩得坑，可以优化的地方还有很多，大家可以在这个基础上自行发挥。

总结一下自己碰到的坑，
1,首先没有在gradle.properties中配置tinker_id，会提示错误tinker_id not set!!!
2,debug没有配置 proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’
导入生成的apk一直没有mapping文件，找了半天才发现

最后说下热修复的大概流程
最终我们需要的是一个patch.apk文件，这个文件是通过老apk和新apk对比生成的,
是通过腾讯自研的dex差异算法得出
算法相关的地址在这里
dex算法

新APK和老APK的mapping必须是一致的，所以我们需要把老APK的mapping保存起来，方便新APK与他对比。
这样就能得到最终的patch，然后调用sdk的TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(), path);
这样就实现了热修复的目的
