那些好玩的gradle

1.Apk拷贝 当我需要把编译出来的Apk统一放到服务器或者某个地方的时候，这个脚本就可以起到作用。

task('copyAll') { android.applicationVariants.all { variant -> variant.outputs.each { output -> if (!output.outputFile.name.contains('unsigned')) { task("copy${variant.name.capitalize()}", type: Copy) { from(output.outputFile) into("/home/huanglei/Download/a/") } dependsOn("copy${variant.name.capitalize()}") } } } }

2.编译后希望打开apk所在位置

task('openApk') { android.applicationVariants.all { variant -> variant.assemble.doLast { //If this is a 'release' build, reveal the compiled apk in finder/explorer if (variant.buildType.name.contains('debug')) { def path = null; variant.outputs.each { output -> path = output.outputFile } exec { if (System.properties['os.name'].toLowerCase().contains('mac os x')) { ['open', '-R', path].execute() } else if (System.properties['os.name'].toLowerCase().contains('windows')) { ['explorer', '/select,', path].execute() } else if (System.properties['os.name'].toLowerCase().contains('linux')) { ['nautilus', path].execute() } } } } } }

3.根据git的计较次数作为VersionCode，可以通过 adb shell dumpsys package com.example.samples 来直接查看versionCode

defaultConfig { versionCode gitCommitCount() ?: 0 } def gitCommitCount() { try { def stdout = new ByteArrayOutputStream() exec { commandLine 'git', 'rev-list', '--count', 'HEAD' standardOutput = stdout } def commitCount = stdout.toString().trim().toInteger() return commitCount } catch (ignored) { return 0; } }

4.根据Git的tag description来设置versionName

defaultConfig { versionName getGitTagName() ?: "1.0.0" } def getGitTagName() { try { def branchout = new ByteArrayOutputStream() exec { commandLine 'git', 'rev-parse', '--abbrev-ref', 'HEAD' standardOutput = branchout } def branch = branchout.toString().trim() if (branch.equals("master")) { def stdout = new ByteArrayOutputStream() exec { commandLine 'git', 'describe', '--dirty' standardOutput = stdout } return stdout.toString().trim() } else { return branch; } } catch (ignored) { return null; } }
