在 app/build.gradle 文件里添加几行代码：
def gitCommitShortHash = 'git log -1 --pretty=%h'.execute([], project.rootDir).text.trim()
def gitCommitDate = 'git log -1 --pretty=%ci'.execute([], project.rootDir).text.trim().split()[]
def gitShortShaDate = gitCommitShortHash + "_" + gitCommitDate // Auto-incrementing commit count based on counting commits to HEAD (Build #543)
def gitCommitCount = Integer.parseInt('git rev-list HEAD --count'.execute([], project.rootDir).text.trim()) // I want to use git tags as my version names (1.2.2)
def gitCurrentTag = 'git describe --tags --abbrev=0'.execute([], project.rootDir).text.trim()
加完之后整个build.gradle文件像这个样子（注意其中的 versionCode gitCommitCount 和 versionName gitShortShaDate）：
apply plugin: 'com.android.application' def gitCommitShortHash = 'git log -1 --pretty=%h'.execute([], project.rootDir).text.trim()
def gitCommitDate = 'git log -1 --pretty=%ci'.execute([], project.rootDir).text.trim().split()[]
def gitShortShaDate = gitCommitShortHash + "_" + gitCommitDate // Auto-incrementing commit count based on counting commits to HEAD (Build #543)
def gitCommitCount = Integer.parseInt('git rev-list HEAD --count'.execute([], project.rootDir).text.trim()) // I want to use git tags as my version names (1.2.2)
def gitCurrentTag = 'git describe --tags --abbrev=0'.execute([], project.rootDir).text.trim() android {

})

testCompile 'junit:junit:4.12'
}
附：
git的 post-commit 类型 hook，post-commit 类型hook创建方法：1、这项目的主目录里创建一个hooks目录，在该目录里放入一个文件 post-commit，改属性: chmod a+x post-commit，
然后将 .git/hooks 目录删除，将自己创建的hooks链接到 .git/ 目录里，进入 .git 目录执行：ln -s ../.hooks/ hooks，为啥要这么做，因为.git/ 目录下的所有文件是没法版本管理的，所以创建到工程目录以便加入版本管理。以后所有hook都放在该目录，且该目录不要忽略（不要放进.gitignore）。
该 post-commit 目录的内容：
#!/bin/bash
commit=$(git log - --pretty=%H%n%ci)
commit_full_hash=$(echo "$commit" | head -) # c7618bf23a71637c54b5e51c37cbace3f6ff4899
# commit_full_hash=$(git log - --pretty=%H) # same as above
# commit_full_date=$(echo "$commit" | head - | tail -) # -- :: +
commit_short_hash=$(git log - --pretty=%h) # c7618bf commit_date=$(git log - --pretty=%ci >/dev/null | cut -d" " -f ) # --
commit_time=$(git log - --pretty="%ci" >/dev/null | cut -d" " -f ) # :: branch_full=$(git symbolic-ref HEAD >/dev/null) # refs/heads/master
branch_simple=$(git symbolic-ref HEAD >/dev/null | cut -d"/" -f ) # master
# branch_simple=$(git symbolic-ref --short -q HEAD)
# branch_simple=$(git name-rev --name-only HEAD)
# branch_simple=$(git symbolic-ref --short -q HEAD) echo "print by hzh --------"
echo "$commit_full_hash"
echo "$commit_short_hash"
echo "$commit_date"
echo "$branch_full"
echo "$branch_simple"
echo "print by hzh end --------\n" # 当然，你可以将这些东西写到version文件里，然后编译的时候读取它，以下只是示例
versionfilename=$(git config hooks.versionfilename)
if [[ -z $versionfilename ]]
then
versionfilename="version"
fi # Version number
#echo \# Generated using git post-commit hook > $versionfilename
echo -n "$commit_time" > $versionfilename
echo -n " " >> $versionfilename
echo -n "$commit_date" >> $versionfilename
echo -n " " >> $versionfilename
echo -n "$commit_short_hash" >> $versionfilename
echo -n " " >> $versionfilename
echo -n "$branch_simple" >> $versionfilename
