我正在开发一个Android应用程序,它使用WiFi(Direct)进行服务发现和P2P对等发现/连接.

我的发展环境如下: -

JRE: 1.8.0_152-release-915-b01 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

我的Gradle构建: -

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.research.wifi_direct"

        minSdkVersion 19
        targetSdkVersion 26

        versionCode 1

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_8
            targetCompatibility JavaVersion.VERSION_1_8
        }
    }
    buildTypes {

        debug {
            buildConfigField "String", "INSTANCE_NAME", "\"_vascodagama\""
            buildConfigField "String", "SERVICE_TYPE", "\"_presence._tcp\""
