前言：

最近工作不是很忙寻思着学习学习一些新技术or热门技术，热修复，听着好高大上啊，安卓高级程序员必会技能（高逼格技能~~）。热修复这一两年确实很火，技术文章满天飞，BAT等大公司都有一套自己的热修复框架，Tinker、Dexposed、AndFix、HotFix、Nuwa等等，热修复有两大流派：

Native，代表有阿里的Dexposed、AndFix与腾讯的内部方案KKFix；
Java，代表有Qzone的超级补丁、大众点评的nuwa、百度金融的rocooFix, 饿了么的amigo以及美团的robust。

Native流派与Java流派都有着自己的优缺点，它们具体差异可以参考这里~~，这些框架GitHub上都有实现原理和踩坑方法~~大家可以根据需求选择最适合自己的热修复框架。好了我们直奔主题！！

一、为什么使用Tinker？

出至腾讯是微信官方的Android热补丁解决方案，我们每使用一个开源框架需要考虑的是性能、兼容性成功率、后期维护等。首先性能和兼容性大家看这里，作为一个拥有9亿用户的超级app，Tinker能够作为微信热修复支撑，极致的性能和兼容性是必须的，也是Tinker开发的初衷，经过了一系列的版本迭代到最新的1.9.2已经越发稳定成熟，然后再是维护，从16年9月第一次发布版本到目前为止更新了17个版本，2178次commit。。。可见微信团队一直在致力维护这个项目，而AndFix已经两年没更新了，issue也是一大堆问题没人解决。。看来阿里爸爸是放弃这个框架了~~~，dexposed也是一个样。。。贴个图各个热修复框架优势对比：

二、开始采坑之旅

1、安卓Tinker集成

新建项目配置project的gradle：ps因为Tinker支持gradle配置，配置属性比较多最好直接拷贝过来再把你原有的gradle属性配置上去（要看懂这些配置属性是什么意思，需要有一定的gradle知识~~~）

buildscript {
    repositories {
        mavenLocal()
        google()
        jcenter()
    }

    dependencies {
        if (project.hasProperty('GRADLE_3') && GRADLE_3.equalsIgnoreCase('TRUE')) {
            classpath 'com.android.tools.build:gradle:3.0.0'
        } else {
            classpath 'com.android.tools.build:gradle:2.3.3'
        }
        classpath "com.tencent.tinker:tinker-patch-gradle-plugin:${TINKER_VERSION}"
    }
}

allprojects {
    repositories {
        mavenLocal()
        google()
        jcenter()
    }
}

def is_gradle_3() {
    return hasProperty('GRADLE_3') && GRADLE_3.equalsIgnoreCase('TRUE')
}

这个会报错：

别急，打开gradle.properties在最后面加入：

TINKER_VERSION=1.9.2
GRADLE_3=true

然后配置app的gradle（我把整个放放出来）：

apply plugin: 'com.android.application'

dependencies {
    if (is_gradle_3()) {
        implementation fileTree(dir: 'libs', include: ['*.jar'])

        compile("com.tencent.tinker:tinker-android-lib:${TINKER_VERSION}") { changing = true }
        provided("com.tencent.tinker:tinker-android-anno:${TINKER_VERSION}") { changing = true }

                        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", "${newFileNamePrefix}-R.txt")
                        }
                    }
                }
            }
        }
    }
    project.afterEvaluate {
        //sample use for build all flavor for one time
        if (hasFlavors) {
            task(tinkerPatchAllFlavorRelease) {
                group = 'tinker'
                def originOldPath = getTinkerBuildFlavorDirectory()
                for (String flavor : flavors) {
                    def tinkerTask = tasks.getByName("tinkerPatch${flavor.capitalize()}Release")
                    dependsOn tinkerTask
                    def preAssembleTask = tasks.getByName("process${flavor.capitalize()}ReleaseManifest")
                    preAssembleTask.doFirst {
                        String flavorName = preAssembleTask.name.substring(7, 8).toLowerCase() + preAssembleTask.name.substring(8, preAssembleTask.name.length() - 15)
                        project.tinkerPatch.oldApk = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-release.apk"
                        project.tinkerPatch.buildConfig.applyMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-release-mapping.txt"
                        project.tinkerPatch.buildConfig.applyResourceMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-release-R.txt"

                    }

                }
            }

            task(tinkerPatchAllFlavorDebug) {
                group = 'tinker'
                def originOldPath = getTinkerBuildFlavorDirectory()
                for (String flavor : flavors) {
                    def tinkerTask = tasks.getByName("tinkerPatch${flavor.capitalize()}Debug")
                    dependsOn tinkerTask
                    def preAssembleTask = tasks.getByName("process${flavor.capitalize()}DebugManifest")
                    preAssembleTask.doFirst {
                        String flavorName = preAssembleTask.name.substring(7, 8).toLowerCase() + preAssembleTask.name.substring(8, preAssembleTask.name.length() - 13)
                        project.tinkerPatch.oldApk = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug.apk"
                        project.tinkerPatch.buildConfig.applyMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug-mapping.txt"
                        project.tinkerPatch.buildConfig.applyResourceMapping = "${originOldPath}/${flavorName}/${project.name}-${flavorName}-debug-R.txt"
                    }

                }
            }
        }
    }
}

在这里特别需要注意的几点：

1）、如果出现这个错误

请检查这个是否配置正确

def getTinkerIdValue() {
    return hasProperty("TINKER_ID") ? TINKER_ID : android.defaultConfig.versionName
}

ps：我拷贝官方demo例子的gradle配置就报这个错，后来把它改成上面一样就行了。

2）、把这个改为true：ignoreWarning = true // 是否忽略有风险的补丁包。这里选择忽略，当补丁包风险时不会中断编译。不然在生成补丁包会出错。

3）、然后就是这个：

tinkerOldApkPath：基础包所在路径

之所以改成old-app.apk，主要是为了区分新的apk和基础包，因为每次build一次都会生成一个apk

虽然每次都不同，你不改下名字根据编号很容易搞错。官方例子是用的apk名称ps：old-app.apk和old-app-mapping.txt很重要！！！你后面制作补丁都需要根据这个基础包来制作，最好保存好并备份！！，如果不小心弄丢了，那就只能推送更新app吧~~~

基础包：指的是发布出去的安装包（用户正在使用的安装包）。

4）、注意这个BuildInfo引用的BuildConfig类：

一开始会报错，找不到这个BuildConfig类，你build一下就出来了。ps：我能说我直接把这个BuildInfo给的PLATFORM改成空了么，在后面打补丁死活打不上~~~~~，主要还是gradle配置不能出错~~~~

这里的字段都是gradle配置的时候生成的。

配置好gradle后build下，看下是否成功，然后切换project视图app>build目录下是否生成bakApk目录，上图所示。

打开gradle操作界面双击TinkerPatchDebug，生成补丁包

切换project视图app>build>outputs>tinkerPatch目录下看是否生成补丁：

解释：

如果失败或者没有生成这些个文件夹，请仔细检查你的gradle配置是否正确~~。

拷贝java文件（官方demo的这些文件~~）：

SampleUncaughtExceptionHandler：Tinker的全局异常捕获器。

MyLogImp：Tinker的日志输出实现类。

SampleLoadReporter：加载补丁时的一些回调。

SamplePatchListener：过滤Tinker收到的补丁包的修复、升级请求。

SamplePatchReporter：修复或者升级补丁时的一些回调。

SampleTinkerReport：修复结果（成功、冲突、失败等）。

SampleResultService：:patch补丁合成进程将合成结果返回给主进程的类。

TinkerManager：Tinker管理器（安装、初始化Tinker）。

TinkerUtils：拓展补丁条件判定、锁屏或后台时应用重启功能的工具类。

这些只是对Tinker功能的拓展和封装，都是可选的，你也可以自己封装。

TinkerApplication，这个类并不是继承Application，如果自己有自定义的application可以把初始化操作放在onCreat()方法里面：

@SuppressWarnings("unused")
@DefaultLifeCycle(application = "com.oking.mytinker.OriginalApplication",// application类名。只能用字符串，这个MyApplication文件是不存在的，但可以在AndroidManifest.xml的application标签上使用（name）
        flags = ShareConstants.TINKER_ENABLE_ALL,// tinkerFlags
        loaderClass = "com.tencent.tinker.loader.TinkerLoader",//loaderClassName, 我们这里使用默认即可!（可不写）
        loadVerifyFlag = false)//tinkerLoadVerifyFlag
public class TinkerApplication extends DefaultApplicationLike {

    private Application mApplication;
    private Context mContext;
    private Tinker mTinker;

    // 固定写法
    public TinkerApplication(Application application, int tinkerFlags, boolean tinkerLoadVerifyFlag, long applicationStartElapsedTime, long applicationStartMillisTime, Intent tinkerResultIntent) {
        super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime, applicationStartMillisTime, tinkerResultIntent);
    }

    // 固定写法
    @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
    public void registerActivityLifecycleCallbacks(Application.ActivityLifecycleCallbacks callback) {
        getApplication().registerActivityLifecycleCallbacks(callback);
    }

    @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
    @Override
    public void onBaseContextAttached(Context base) {
        super.onBaseContextAttached(base);
        mApplication = getApplication();
        mContext = getApplication();
        initTinker(base);
        // 可以将之前自定义的Application中onCreate()方法所执行的操作搬到这里...
    }

    private void initTinker(Context base) {
        // tinker需要你开启MultiDex
        MultiDex.install(base);

        TinkerManager.setTinkerApplicationLike(this);
        // 设置全局异常捕获
        TinkerManager.initFastCrashProtect();
        //开启升级重试功能（在安装Tinker之前设置）
        TinkerManager.setUpgradeRetryEnable(true);
        //设置Tinker日志输出类
        TinkerInstaller.setLogIml(new MyLogImp());
        //安装Tinker(在加载完multiDex之后，否则你需要将com.tencent.tinker.**手动放到main dex中)
        TinkerManager.installTinker(this);
        mTinker = Tinker.with(getApplication());
    }

    @Override
    public void onCreate() {
        super.onCreate();
        // 将之前自定义的Application中onCreate()方法所执行的操作搬到这里...

        String appId = "20171213203556412-8689";
        String appSecret = "cd34d15329cb4caeac3bbd4dc335707d";
        PatchManager.getInstance().init(getApplication(), "http://192.168.0.105:8080/hotfix-apis", appId, appSecret, new IPatchManager() {
            @Override
            public void cleanPatch(Context context) {
//                TinkerInstaller.cleanPatch(context);
            }

            @Override
            public void patch(Context context, String patchPath) {
//                TinkerInstaller.onReceiveUpgradePatch(context, patchPath);
                Contact.patchPath = patchPath;
                System.out.println("patch："+patchPath);

            }
        });
        PatchManager.getInstance().register(new Listener() {
            @Override
            public void onQuerySuccess(String response) {
                Log.d("TinkerApplication","获取补丁成功"+response);
            }

            @Override
            public void onQueryFailure(Throwable e) {
                Log.d("TinkerApplication","获取补丁失败"+e.getMessage());
            }

            @Override
            public void onDownloadSuccess(String path) {
                Log.d("TinkerApplication","下载补丁成功"+path);
            }

            @Override
            public void onDownloadFailure(Throwable e) {

            }

            @Override
            public void onPatchSuccess() {

            }

            @Override
            public void onPatchFailure(String error) {

            }

            @Override
            public void onLoadSuccess() {

            }

            @Override
            public void onLoadFailure(String error) {

            }
        });
        PatchManager.getInstance().setTag("");
        PatchManager.getInstance().setChannel("");
        PatchManager.getInstance().queryAndPatch();
    }
}

清单文件：

权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET"/>

application

这个文件是动态生成，不存在我们项目中的，但是我们项目是可以引用的

android:name=".OriginalApplication"

Service

<service
    android:name="com.oking.mytinker.tinker.SampleResultService"
    android:exported="false"/>

三、服务器搭建

放个Github地址

1、下载部署所需要的文件(war包、配置文件、建库sql文件) war包下载.

2、在mysql(需要5.x版本)里面建数据库,建表sql在patchserver-manager/import.sql中

3、把hotfix-apis.properties和hotfix-console.properties两个配置文件放到/opt/config(*如果是windows部署，放置在tomcat对应的盘符下，假如tomcat在d://tomcat 目录配置文件就放在d://opt/config目录下，并且修改里面对应的配置(数据源配置、访问路径配置、补丁存放目录)

4、把hotfix-apis.war hotfix-console.war放到tomcat下面的webapps目录下

等服务启动完毕就可以在浏览器上访问http://localhost:8080/hotfix-console

会配置Tomcat或者会一点Javaee方面的知识的部署起来会很容易。

下载Tomcat配置好环境变量

安装数据库Mysql新建数据库patch_manager，ps：注意名称要和配置文件数据库名称一致

修改hotfix-apis.properties配置文件

修改hotfix-console.properties文件

注意上面加粗说明，文件别放错了！！给个部署参照

拷贝war包到tomcat的webapp目录下

运行Tomcat服务器

访问地址，注册登录。

到目前为止我们已经把Tinker集成好了，服务器也部署成功了，下面我们来撸代码~~~

四、撸代码、实操

app的Gradle加入一行

compile 'com.dx168.patchsdk:patchsdk:1.2.7'

上面集成Tinker的时候有加上就不用加了

TinkerApplication的onCreat方法里面加入：

        String appId = "20171214154046922-6495";
        String appSecret = "9f820d28ac854e9a82e755fefd69ea63";
        PatchManager.getInstance().init(getApplication(), "http://192.168.0.105:8080/hotfix-apis", appId, appSecret, new IPatchManager() {
            @Override
            public void cleanPatch(Context context) {
//                TinkerInstaller.cleanPatch(context);
            }

            @Override
            public void patch(Context context, String patchPath) {
//                TinkerInstaller.onReceiveUpgradePatch(context, patchPath);
                Contact.patchPath = patchPath;
                System.out.println("patch："+patchPath);

            }
        });
        PatchManager.getInstance().register(new Listener() {
            @Override
            public void onQuerySuccess(String response) {
                Log.d("TinkerApplication","获取补丁成功"+response);
            }

            @Override
            public void onQueryFailure(Throwable e) {
                Log.d("TinkerApplication","获取补丁失败"+e.getMessage());
            }

            @Override
            public void onDownloadSuccess(String path) {
                Log.d("TinkerApplication","下载补丁成功"+path);
            }

            @Override
            public void onDownloadFailure(Throwable e) {

            }

            @Override
            public void onPatchSuccess() {

            }

            @Override
            public void onPatchFailure(String error) {

            }

            @Override
            public void onLoadSuccess() {

            }

            @Override
            public void onLoadFailure(String error) {

            }
        });
        PatchManager.getInstance().setTag("");
        PatchManager.getInstance().setChannel("");
        PatchManager.getInstance().queryAndPatch();

我们登录补丁管理后台，创建应用后面会得到appId和appSecret,保存好：

用过第三方平台的都明白是什么意思，这个也是一样的。

创建一个版本：

在AS中build project

然后把安装包并发送到手机上进行安装（ps我这直接改了名字了~~）：

安卓界面我们长这样~~~ps注意中间文本和Toast~：

假设我们项目上线了突然出现紧急bug（如果用检测更新推送新安装包，这个用户体验就很不好了~~安装包不要流量？一个小小的bug就让我下载安装包更新？差评啊，卸载~~~）

我们修复好的代码：

然后，我们找到上个版本安装包和txt文件把它放在bakApk目录下改名为old-app，切换到gradle视图双击tinkerPatchDebug：

找到patch_signed_7zip.apk补丁包，拷贝到桌面

进入补丁管理后台上传补丁：

发布补丁：

重新打开app点击“修复”按钮：

查看控制台打印日志

app界面有修复成功提示

然后点退出，重新打开应用我们上面修改的代码都同步到app上来了，用户不用重新下载安装包且无感知修复bug：

整个热修复过程就这样~~~说实话有点复杂~~

ps：修复成功后再点击修复按钮是没用的，一个补丁成功完成一次修复使命也就结束了，同时补丁文件也被删除了（不用担心补丁塞满sd卡啥的~~），即使你再次用同一个补丁也是打不了补丁的，这就是补丁的作用，Tinker为我们做了处理，不过你可以卸载某个版本的补丁或者全部补丁~~~，具体请看文档。。。。

五、总结

Tinker的热修复远不止我讲的这些像资源文件、so、library修复等，更深层次原理性的东西还需要进一步去学习~~~官方WIKI文档。

关于那个补丁管理平台，开源的后台，下发补丁，管理补丁、补丁统计、黑名单机制等等。还有源代码，有兴趣的大佬可以去研究研究改造改造~~，这样我们就不用出钱给第三方补丁平台了。。。如果单纯的就下发补丁，可以不用这个平台，后台写个类似版本更新的接口就可以，下载文件>修复。平台的好处就是更加方便、智能化管理、统计数据。
