经典蓝牙双机控制 APP-完整版1第一步创建总开关最重要文件app/src/main/java/com/bt/BuildConfig.javapackagecom.bt;/** * 条件编译开关 * true 服务端被控端 · 被控制的手机 * false 客户端控制端 · 主控手机 */publicclassBuildConfig{// 只改这里 publicstaticfinalbooleanSERVER_MODEfalse;}第二步完整工程所有文件全部复制粘贴1. 项目根文件settings.gradlepluginManagement { repositories { google() mavenCentral() } } dependencyResolutionManagement {
