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)
                    }
                }
            }
 

調整後

            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
