关于什么是TInker，Tinker的官方文档里面有一句话：Tinker是微信官方的Android热补丁解决方案，它支持动态下发代码、So库以及资源，让应用能够在不需要重新安装的情况下实现更新。当然，你也可以使用Tinker来更新你的插件。
第一步：项目的build.gradle的文件支持插件（这里有提示错误信息，所以用gradle3.2.1）
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.tencent.tinker:tinker-patch-gradle-plugin:1.9.1'
第二步：项目里的app.gradle的文件配置
apply plugin: 'com.android.application'//之后
apply plugin: 'com.tencent.tinker.patch'
defaultConfig{
....//你的其他配置
//开启分包
multiDexEnabled true
//注解
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath = true
}
}
//分包配置文件 文件在Tinker有下载，本文最后也会写上
multiDexKeepProguard file('tinker_multidexkeep.pro')
}
//开启大项目模式
dexOptions {
jumboMode = true
maxProcessCount 4
javaMaxHeapSize "2g"
}
dependencies{
..//你的其他依赖
implementation "com.android.support:multidex:1.0.1"
compileOnly('com.tencent.tinker:tinker-android-anno:1.9.1')
implementation('com.tencent.tinker:tinker-android-lib:1.9.1')
}
第三步:同样是在app.gradle里面配置 加到最后面就行了 这是必须配置的 官方的
//定义一个存放oldapk的文件夹
def bakPath = file("${buildDir}/bakApk/")
ext {
//开放项目阶段设置为false，等项目要上架了再设置为true
tinkerEnabled = true
//for normal build
//就是基础包，就是你要修复上架的应用的apk，tinker会根据这个apk名字去打补丁包
tinkerOldApkPath = "${bakPath}/app-debug-0613-10-32-39.apk"
//基础包的混淆文件
tinkerApplyMappingPath = "${bakPath}/app-debug-1018-17-32-47-mapping.txt"
//基础包的R.txt资源索引文件
tinkerApplyResourcePath = "${bakPath}/app-debug-1018-17-32-47-R.txt"
//如果你要编译多个不同版本的apk，否则忽略它
//tinkerBuildFlavorDirectory = "${bakPath}/app-1018-17-32-47"
}

//默认不忽略警告，当设置为true,注意以下情况时会退出打补丁包或者打补丁失败

//2.加了新的四大组件（1.9.0可以加入非export的Activity）到Android配置文件
//3.tinker的dex没打包进main.dex，tinker就不工作了
//4.tinker类是用来加载补丁dex的，改变他们是没用的，虽然不会崩溃，但是改变是无效的，可以忽略它
//5.资源修改了，没用新的mapping.txt去编译

* tinkerId is use to identify the unique base apk when the patch is tried to apply.
* we can use git rev, svn rev or simply versionCode.
* we will gen the tinkerId in your manifest automatic
*/
//保持基础包和补丁包的tinkerid一样，才能打入补丁，我们会把tinkerid编译到androidmanifest文件
tinkerId = getTinkerIdValue()

dex {

* or you want to save rom or check quicker, you can use raw mode also
*/
//这里有jar和raw模式给你选，raw模式就是保持dex格式，jar就是重新把多个dex打包进jar

}
}
基本接入就完成了，补丁包如何生成，tinkerOldApkPath 名字和 自己的包名字一样，然后gradle-tinker-path就可以生成一个patch_signed_7zip.apk文件，这就是补丁。在outputs/tinkerPath目录下。
代码中执行修复代码:
TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(),
Environment.getExternalStorageDirectory().getAbsolutePath() + "/patch_signed_7zip.apk");
如果返回-2之类的错误，一般就是权限问题，7.0问题，以及路径问题。
