腾讯热修复Tinker的详解和使用

1. 热修复概述

2.Tinker的概述(本介绍是从官网上截取的)

tinker-patch-gradle-plugin

tinker-android-lib

tinker-patch-cli.jar

2.1 Tinker和阿里的AndFix、美团的Robust以及QZone的比较

2.2 Tinker的已知问题

"TinkerRuntimeException:checkDexInstall failed"

3. Tinker 接入指南

3.1 添加依赖

tinker-patch-gradle-plugin

dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
classpath ('com.tencent.tinker:tinker-patch-gradle-plugin:1.8.0')// tinker的pluggin
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}

dependencies {
//可选，用于生成application类
provided('com.tencent.tinker:tinker-android-anno:1.8.0')
//tinker的核心库
compile('com.tencent.tinker:tinker-android-lib:1.8.0')
//分包库  下面用得到
compile 'com.android.support:multidex:1.0.1'
}

//apply tinker插件
apply plugin: 'com.tencent.tinker.patch'

tinkerId is not set!!!

3.2 app中的build.gradle中的具体配置参数与介绍

3.2.1 讲一讲参数的意思

tinkerPatch

build/outputs/tinkerPatch

dexMode

buildConfig

不设置applyMapping也不会影响任何的assemble编译

R.txt

可以减少补丁包的大小

避免由于ResId改变导致remote view异常

keepDexApply

dex

lib

res

务必注意的是，只有满足pattern的资源才会放到合成后的资源包。

packageConfig

sevenZip

3.2.2 根据我的 build.gradle 或者官网的 build.gradle 配置自己的build.gradle,其实我的跟官网的一样,就改了一下javaversion,其他的默认就可以

3.2.3 制作签名文件与build.gradle中的相对应

signingConfigs {
release {
try {
storeFile file("../demojks.jks") // .. 就是项目的根目录  demo.jks与app目录同级
storePassword '123456'
keyAlias 'demojks'
keyPassword '123456'
} catch (ex) {
throw new InvalidUserDataException(ex.toString())
}
}

debug {
storeFile file("../demojks.jks")
storePassword '123456'
keyAlias 'demojks'
keyPassword '123456'
}
}

3.3 模拟线上apk制作(也就是发布到市场的apk)

@DefaultLifeCycle(application = ".MyApplication",//而这个类是真正的自定义的application,别忘了在AndroidManifest.xml中使用
flags = ShareConstants.TINKER_ENABLE_ALL,
loadVerifyFlag =true)
public class MyApplicationLike extends ApplicationLike {
public MyApplicationLike(Application app
b96e
lication, 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();
}
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 加载补丁
loadPatch();
}

private void loadPatch() {
String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/patch.apk";
File file = new File(path);
if (file.exists()){
// 加载补丁
TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(), path);
}else {
Toast.makeText(this, "补丁不存在", Toast.LENGTH_SHORT).show();
}
}

public void test(View view) {
int i=1/0;  // 当点击这个button的时候肯定会崩溃
}

3,3.1 运行:

3.3.2 demo.apk和补丁apk都必须是release版本,把Build Variant改为release版本,如下图

3.3.3 运行完之后看下图位置,这个apk就是你打包完成,发布在线上的apk

3.4 补丁包apk 打包

public void test(View view) {
//        int i=1/0;
Toast.makeText(this, "我被修好了,不崩溃了", Toast.LENGTH_SHORT).show();
}

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 = "${bakPath}/app-release-1026-17-04-59.apk"
//proguard mapping file to build patch apk
tinkerApplyMappingPath = "${bakPath}/app-release-1026-17-04-59-mapping.txt"
//resource R.txt to build patch apk, must input if there is resource changed
tinkerApplyResourcePath = "${bakPath}/app-release-1026-17-04-59-R.txt"

//only use for build all flavor, if not, just ignore this field
tinkerBuildFlavorDirectory = "${bakPath}/app-release-1026-17-04-59"
}
