项目中用到经常碰到从github 或者厂商提供的源码, 但是版本比较低, 需要升级到最新的编译环境:
1.修改 project 目录下的 build.gradle:
buildscript {repositories {google()jcenter()}dependencies {classpath 'com.android.tools.build:gradle:3.2.0' //升级gradle 插件版本}
}allprojects {repositories {google()jcenter()}
}dependencies {
}
2.修改 project 下的 /gradle/wrapper/ gradle-wrapper.properties:
#Wed Nov 14 10:07:31 CST 2018 distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip //修改该版本
3.修改model 中的 build.gradle:
android {compileSdkVersion 27buildToolsVersion '27.0.3'defaultConfig {applicationId "com.example.iot_test1"minSdkVersion 15targetSdkVersion 27ndk {moduleName "libspeex"}}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'}}productFlavors {}
}dependencies {//compile 'com.android.support:gridlayout-v7:27.1.1'compile 'com.android.support:appcompat-v7:27.1.1'compile files('libs/com.ibm.micro.client.mqttv3.jar')
