| applicationVariants.all { variant ->
variant.outputs.each { output ->
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast{
copy {
from variant.mappingFile
into "${projectDir}/mappings"
rename { String fileName ->
"mapping-${variant.name}-${variant.versionName}_${variant.versionCode}.txt"
}
}
}
}
}
}
|
除此之外还可以切换test目录
将会在项目根目录/mappings/生成文件mapping-release-1.1_2.txt，这样解决了每次发布版本总是需要在build/outputs/release/mapping.txt中找到并移动出来进行备份的问题.

设置编译时间

| buildConfigField "long", "BUILD_TIME", System.currentTimeMillis() + "L"
|
设置这个之后方便查看编译时间,哪怕是开发xposed插件 用这个可以方便查看是否更新生效,根据编译时间来判断.

优化so库压缩体积排除其他平台可自动兼容

//APP的build.gradle设置支持的SO库架构
abiFilters 'armeabi-v7a'
}

这样的话夜神模拟器和真机测试时没毛病的,体积也节省了不少,QQ也是这样做的哈!
缺点就是开发工具会对于没有所指定的会强制不让运行，但是不这样指定的话，如果极光有5个so,但是自己只有一个armebi-v7a的，没法放开，放开也会崩溃，所以还是得下面得方法。
排除指定文件不打包

只保留armebi-v7a

这里只是演示排除非 armeabi-v7a 目录的so文件,除了排除so还可以排除资源文件哦!

这样以后如果某个模块不要了，删除图片和布局文件，操作速度也是非常快的.
编译生成版本号
编译修改app-release.apk为app应用名称-版本名-版本号.apk
网上有些方法实际上是有bug的，需要经常刷新,每次改版本的时候或者时间变化的时候需要重新build,我这个方法没有bug.

| archivesBaseName = "情迁神器${versionName} build_${versionCode}".replace(' ', '_')

这个东西放到defaultConfig节点下即可.

通过这种方式可以有效减少重复资源
