android studio升級3.0版本，問題處理

問題1：編譯版本與構建版本修改

compileSdkVersion : 26, 
buildToolsVersion : “26.0.2”, 
gradle版本： 
distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip 
classpath ‘com.android.tools.build:gradle:3.0.0’

問題2：apk名稱配置調整，build有一個outputFileName ，直接配置

Error:(120, 0) Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl. <a href="openFile:D:\Android\workspace_zhy\qufish_office\app\build.gradle">Open File</a>

            //輸出apk配置 applicationVariants.all { variant -> variant.outputs.each { output -> def outputFile = output.outputFile if (outputFile != null && outputFile.name.endsWith('.apk')) { // 輸出apk名稱 def fileName if (variant.buildType.zipAlignEnabled) { //正式版本 fileName = "XX_${defaultConfig.versionName}_${packageTime()}_${buildType.name}.apk" } else { fileName = "XX_${defaultConfig.versionName}_${packageTime()}_${buildType.name}.apk" } output.outputFile = new File(outputFile.parent, fileName) } } }

調整后

            applicationVariants.all {
                outputs.all {
                    // 輸出apk名稱
                    def newApkName
                    if (buildType.zipAlignEnabled) { newApkName = "XX_${defaultConfig.versionName}_${packageTime()}_${buildType.name}.apk" } else { newApkName = "XX_${defaultConfig.versionName}_${packageTime()}_${buildType.name}.apk" } outputFileName = newApkName } }

問題3：如果你有配置多渠道包，會報錯dimension

//android{}內
flavorDimensions "color" productFlavors { baidu { //每個渠道多家一個這個配置 dimension "color" ... } }

問題4：

compile ‘com.android.support:multidex:1.0.1’

倉庫位置調整到google，需要在配置倉庫的地方加入google()（報錯的時候直接點擊下也可以自動添加這個倉庫），另外multidex的版本號升級到1.0.2

allprojects { repositories { jcenter() mavenCentral() maven { url 'https://jitpack.io' } google() } }

問題5：

解決方法:

在項目的gradle.properties中： 
android.enableAapt2=false
