Solutions for some compilation errors in Android engineering

1. Some problems were found with the configuration of task ':app:generateSafeArgsDebug' (type 'ArgumentsGenerationTask').
   Type 'androidx.navigation.safeargs.gradle.ArgumentsGenerationTask' property 'applicationId' is missing an input or output annotation.
   Solution: Yes Because the version of the navigation-safe-args-gradle-plugin plugin is too low, just modify the version number, for example

    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:1.0.0"

change into

    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.3.0"

2. Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven(http://maven.aliyun.com/nexus/content/groups/public)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See ...
   Solution: Set the allowInsecureProtocol property setting of the corresponding maven library
   to

   maven {
    
    
      allowInsecureProtocol = true
      url 'http://maven.aliyun.com/nexus/content/groups/public/'
     }

3. this.activity?.let{…}
   kotlin-related keywords such as let and also are marked in red and need to be added to the project's build.gradle file

   dependencies {
    
    
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.10" 
    }

Add in the app's build.gradle file

 dependencies {
    
    
        implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.6.10"
    }
