Tinker热修复

Tinker是一款优秀的热修复框架，它是基于TINKER_ID来对基准包进行修复的，比如旧版本的包（即安装在手机的包）和新旧版本包的补丁，它们的TINKER_ID应该是一样的，那么它就可以修复。

配置apt选项

javaCompileOptions { 
    // Tinker需要 
    annotationProcessorOptions {
        includeCompileClasspath = true
    }
}

代码混淆

multiDexKeepProguard file("tinker_multidexkeep.pro")

修复逻辑

比如Host+补丁A，会换成Host+补丁B，而不是Host+A+B

关键类

class MusicApp(private val application: Application?) : Application(), AppConfig { 

    var mediaManager: MediaManager? = null 
        private set 
    private var refWatcher: RefWatcher? = null 
    
    companion object { 
        @JvmStatic var instance: MusicApp? = null 
            private set 
    }
    
    override fun attachBaseContext(base: Context) {
        super.attachBaseContext(base) 
        //dex分包 
        MultiDex.install(base) 
    }
}
