Android 热更新之tinker
何为热更新?但我们刚刚上线app突然收到反馈有BUG存在,这时候,重新发布apk更新版本是相当麻烦,成本高,或许说你app有更新版本的功能,这时候用户体验非常差,又消耗流量,分分钟触发用户卸载你的应用,那就尴尬了.最近出现不少热门的热修复框架.
阿里的AndFix:在Native层使用指针替换的方式替换bug方法，已达到修复bug的目的
QZone的方案 Nuwa 、 HotFix 、 DroidFix:通过ClassLoader实现,Android Dex分包方案.
- 美团robust:基于InstantRun原理,编译期给每个类每个方法都加上修复功能,自动插入代码.
- 腾讯的Tinker:采用的InstantRun的资源补丁方式，全量替换资源
各有各的优势,下面是官网统计的数据.
今天尝试了下tinker,也遇到不少坑.
1,项目的最外层project的build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.1'
classpath ('com.tencent.tinker:tinker-patch-gradle-plugin:1.7.9')
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}2.为了走少点坑路.建议复制一份官网demo中build.gradle下来
3.继承DefaultApplicationLike,重写application
@SuppressWarnings("unused")
//在AndroidManifest中配置application时用到就是这个类
//这个类是自动生成的
@DefaultLifeCycle(application = "tinker.sample.android.app.SampleApplication",
flags = ShareConstants.TINKER_ENABLE_ALL,
loadVerifyFlag = false)
public class SampleApplicationLike extends DefaultApplicationLike {
private static final String TAG = "Tinker.SampleApplicationLike";
public SampleApplicationLike(Application application, int tinkerFlags, boolean tinkerLoadVerifyFlag,
long applicationStartElapsedTime, long applicationStartMillisTime, Intent tinkerResultIntent) {
super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime, applicationStartMillisTime, tinkerResultIntent);
}
/**
* install multiDex before install tinker
* so we don't need to put the tinker lib classes in the main dex
*
* @param base
*/
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
public void onBaseContextAttached(Context base) {
super.onBaseContextAttached(base);
//you must install multiDex whatever tinker is installed!
MultiDex.install(base);
TinkerInstaller.install(this);
}
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public void registerActivityLifecycleCallbacks(Application.ActivityLifecycleCallbacks callback) {
getApplication().registerActivityLifecycleCallbacks(callback);
}
}记得在AndroidManifest中配置application
4, 接下来正常来说是你要使用签名打包apk,如果打包成功会在build生成一个bakAPK的文件夹,里面有你当前打包版本的apk(注意:图中的红框是我复制正式签名版本apk进去的)
但是这个流程的坑真心多.如果你没有配置git你会遇到抛出这样一个错误
(can't get git rev, you should add git to system path or just input test value, such as 'testTinkerId'")
说明你没有配置git,或者设定一个版本号作为id,这里直接修改gitRev=”1.0.0”,如图.
build.gradle中配置oldapk:名称
tinkerOldApkPath = “${bakPath}/app-release.apk”(和步骤4图的一致)
bakPath:指的是build/bakApk的路径下.
app-release.apk:是你旧版本(有bug).
如上图我们把打包正式签名apk负责到bakAPK文件夹下,由于现在是测试,,假如当前版本是有bug.修改bug之后,,我们要获取的是修改bug后的补丁文件(patch_singed_7zip.apk),那就要生成最新(无bug)版本,在Terminal中输入gradlew tinkerPatchDebug
成功如图:
在build\outputs\tinkerPatch\release\patch_signed_7zip.apk有这样一个文件生成.
把patch_singed_7zip.apk补丁文件存放到你代码中所要加载的路径中.这里方便测试,理论上这个文件应该通过一个接口获取,判断是否有补丁文件,有就进行补丁修复.
打开有bug的应该,点击加载,后2-3s出现自动关闭应用,再次打开应用就可以加载新的内容.
最后献上build.gradle所有代码,基本与官网一样
