Thinker热修复

1、热修复是什么？

简单来讲就是在不需要发包的情况下，修改你线上的应用bug,这样就不用因为一个小bug而再次发包了

2、接入方式

一种是命令行接入，一种是gradle接入

下面讲解的是gradle接入
首先，基本的配置
在peoject的build中配置如下

TINKER_VERSION需要在gradle.properties中进行配置

TINKER_VERSION=1.7.7

这里这样写的目的是把资源统一管理，接下来是配置app的build，官方文档推荐我们使用这个
https://github.com/Tencent/tinker/blob/master/tinker-sample-android/app/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

1、buildConfigField “String”, “TINKER_ID”, “\”${getTinkerIdValue()}\”“

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

1、ildConfigField “String”, “TINKER_ID”, “\”1.0\”“

我直接写死，需要git提交记录作为tinker_id的也可以按照官方文档推荐的写
同时，这些地方也可以相应的替换掉

//废弃/*def getTinkerIdValue() {    return hasProperty("TINKER_ID") ? TINKER_ID : gitSha()}*/ tinkerId = "1.0"/*getTinkerIdValue()*/

接下来修改自己的签名文件,我这里配置的文件路径是自己电脑上面的，这个位置大家需要修改为自己的签名文件路径，也可以按照我的去生成一个签名文件，我相信这个还是很简单的

  //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 {        release {            try {                keyAlias 'china'                keyPassword '123456'                storeFile file('D:/work/release.jks')                storePassword '123456'            } catch (ex) {                throw new InvalidUserDataException(ex.toString())            }        }        debug {            storeFile file('D:/work/debug.jks')            keyAlias 'china'            keyPassword '123456'            storePassword '123456'        }    }

 buildTypes {        release {            minifyEnabled true            signingConfig signingConfigs.release            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }        debug {            debuggable true            minifyEnabled false            signingConfig signingConfigs.debug            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }

官网文档没有设置debug的 proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’也就是说没有应用混淆文件，这样是不会生成mapping文件的，所以这里我也加上

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                        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")                        }                    }                }            }        }

这下面主要是设置生成的文件所在的目录是什么
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.app.Application;import android.content.Context;import android.content.Intent;import android.support.multidex.MultiDex;import com.tencent.tinker.anno.DefaultLifeCycle;import com.tencent.tinker.lib.tinker.TinkerInstaller;import com.tencent.tinker.loader.app.ApplicationLike;import com.tencent.tinker.loader.shareutil.ShareConstants;@DefaultLifeCycle(application = ".SimpleTinkerInApplication",        flags = ShareConstants.TINKER_ENABLE_ALL,        loadVerifyFlag =true)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);    }    @Override    public void onBaseContextAttached(Context base) {        super.onBaseContextAttached(base);        MultiDex.install(base);        TinkerInstaller.install(this);    }    @Override    public void onCreate() {        super.onCreate();    }}

这个application官网有提供的，也可以copy我的，ApplicationLike 并不是一个application
真正的application是@DefaultLifeCycle(application = “.SimpleTinkerInApplication”,这个
所以在androidmanifest中配置applica的name

<application        android:name=".SimpleTinkerInApplication"        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <activity android:name=".MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN"/>                <category android:name="android.intent.category.LAUNCHER"/>            </intent-filter>        </activity>    </application>    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

同时配置读取sd卡的权限
接下来测试

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    xmlns: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">    <TextView        android:id="@+id/tv"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="111"/>    <Button        android: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111
然后设置按钮调用onclick

package com.anlaiye.swt.gradletest;import android.os.Bundle;import android.os.Environment;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Toast;import com.tencent.tinker.lib.tinker.TinkerInstaller;import java.io.File;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }        //加载补丁        public void loadPath(View view) {            String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/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);            }else {                Toast.makeText(this, "补丁已经不存在", Toast.LENGTH_SHORT).show();            }        }}

然后我运行APP
会生成如下的目录结构

同时界面效果

接下来做如下修改

注意这里是release版本，不能debug版本,release版本混着来，比如oldapk是debug版本，新的apk是release版本，这样是不行的，统一用release版本
这里我将对应路径改为bakapk中第一次运行生成的apk文件名字，比如第一次生成的apk文件名为app-release-1115-10-49-30.apk,所以我把tinkerOldApkPath 的路径后面的名字修改为对应的app-release-1115-10-49-30.apk，mapping文件和R文件路径也要对应修改，最后一项tinkerBuildFlavorDirectory 可以忽略，我一直觉得这里太死板，应该像设置tinker_id那样对这里进行动态的配置，不用每次都来修改
接下来我把textview改成2222，用来和第一次作区别

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，点击更新按钮
点击后如下

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。
