@zeng1990java 项目中是否有指定的flavor呢？有的话需要配置一下..例如：

freeline {
    hack true
    productFlavor "dev"
}

[zeng1990java]

有，
productFlavors {
fir {
}
}
没看懂你说要配置什么

[lomanyong]

@zeng1990java 你们平时的打包命令是什么呢？比如如果是gradlew.bat assembleFirDebug的话，则flavor为Fir，则需要配置为：

freeline {
    hack true
    productFlavor "fir"
}

多谢，成功了，但是耗时还是一样的，看输出主要是install apk和clean build task和耗时很多，你看正常吗

@zeng1990java 你可以修改一下代码再执行一下python freeline.py看下。

freeline并不加速全量编译，主要是加速增量编译。在增量编译前，需要有一个全量编译的底包作为基线包。经过一次全量编译后，再执行python freeline.py就会进行增量编译了。如果遇见build.gradle以及AndroidManifest.xml之类的修改，freeline会自动执行全量编译重新打基线包。

新建了一个只有一个MainActiivty和一个Application的工程，不管有没有改代码，每次的执行结果基本都要28秒多，不用freeline的时候也是这么久，不知道是不是使用的姿势不对

[lomanyong]

@zeng1990java 看日志提示猜测你的目标设备上装了多个依赖freeline的app，这个会导致基线对齐失败重新打全量包。估计目标设备上还安装了freeline sample这个app，可以卸载掉后重新试试看。

[zeng1990java]

对，我把其他使用了freeline的Demo项目删除后就是可以了，非常感谢你的解答 @lomanyong

[charvenhe]

@zeng1990java 方便的话在你们的项目试试，看看增量模式下，资源或代码修改耗时多少，跟你们原来相比如何

[zeng1990java]

@charvenhe 集成了，小改动的话2秒以内。但是好像不支持打包的时候改包文件名称，需要注释掉如下代码

applicationVariants.all { variant ->
        variant.outputs.each { output ->
            def outputFile = output.outputFile
            def outputDirPath = project.hasProperty('outputPath') ? outputPath : outputFile.parent
            if (outputFile != null && outputFile.name.endsWith('.apk')) {
                def fileName
                if(project.hasProperty('outputPath')){
                    // 输出apk名称为Merchant_v1.0_SoftwareUpdate_release.apk
                    fileName = "Merchant_v${defaultConfig.versionName}_${variant.productFlavors[0].name}_${variant.buildType.name}.apk"
                }else{
                    // 输出apk名称为Merchant_v1.0_2015-01-15_SoftwareUpdate_release.apk
                    fileName = "Merchant_v${defaultConfig.versionName}_${releaseTime()}_${variant.productFlavors[0].name}_${variant.buildType.name}.apk"
                }

                output.outputFile = new File(outputDirPath, fileName)
            }
        }
    }

[charvenhe]

@zeng1990java ,apk path 你可以通过DSL指定

freeline {
...
apkPath "your apk path"
}

[zeng1990java]

可以了，多谢 @charvenhe

[charvenhe]

@zeng1990java 不客气，可以在你们项目多试试，资源增量也试试看看有没问题

[zeng1990java]

@charvenhe 恩
