Android常见编译问题总结

一、Grale配置问题

1、Unknown host 'downloads.gradle-dn.com'. You may need to adjust the proxy settings in Gradle.

distributionUrl=https\://mirrors.aliyun.com/macports/distfiles/gradle/gradle-6.5-all.zip

2、Caused by: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

Unsupported Java.
Your build is currently configured to use Java 17.0.7 and Gradle 6.5.
解决方案：下载低版本的jdk，然后配置对应路径

3、Failed to find Platform SDK with path: platforms;android-30

Could not find compile target android-30 for modules :app, :bottomnavigation

解决方案：将画线的两个文件里面的 compileSdkVersion 改成自己下载的Android Sdk版本
