android 多渠道腳本

原創內容，轉載請註明出處

背景

多渠道打包這個本沒啥難度，可是按照官方的作法通常都要從新編譯 apk, 當 apk 很大的時候，會很是耗時，美團已經提供了一種解決思路，請點擊這裏查看美圖的思路, 以前有個羣裏的同窗想讓我將他寫的 python 代碼改爲 shell,  很久沒寫 shell 也想增長點熟練度，因此便欣然贊成了。

功能

將工做目錄下指定的 apk 文件夾中的 apk 進行復制，而後在新的 apk 的 meta-info 目錄下建立一個空的文件，這個文件以 channel.txt 中指定的渠道命名

代碼

shell腳本實現

# !/usr/bin/bash

  model=$1

channel_file=$2 # 空文件 便於寫入此空文件到apk包中做爲channel文件 src_empty_file='czt.txt' # 建立一個空文件（不存在則建立） if [ -e $src_empty_file ]; then rm -i $src_empty_file fi touch $src_empty_file if [ ! $? -eq 0 ]; then exit 1; fi # 獲取當前目錄中全部的apk源包 src_apks=()
if [ "$model" = "" ];then
　　file_path="."
 else 　　file_path="./$model"
fi
 for file in $(cd $file_path ; ls); do
 file=${file_path}$file
 if [ -f $file ];then basename $file | grep '\.apk$' && src_apks=("${src_apks[@]}" "$file") fi done # 獲取渠道列表 if [ "$channel_file" = "" ];then channel_file='channel.txt' fi f=$(cat $channel_file) function copy(){ if [ ! -e $1 ];then return 1 fi cp $1 $2 } for src_apk in ${src_apks[@]};do # file name (with extension) src_apk_file_name=$(basename $src_apk) # 分割文件名與後綴 src_apk_name=${src_apk_file_name%.apk} # 後綴名，包含. 例如: ".apk " src_apk_extension=${src_apk_file_name##*.} # 建立生成目錄,與文件名相關 output_dir='output-'${src_apk_name}/ if [ -e $output_dir ]; then rm -r $output_dir fi mkdir -p $output_dir # 遍歷渠道號並建立對應渠道號的apk文件 for line in $f;do target_channel=$line target_apk=${output_dir}${src_apk_name}-${target_channel}${src_apk_extension} echo "${output_dir}=======>${src_apk_name}=======>, ${target_channel} =======>, ${src_apk_extension} =======>" # 拷貝創建新apk cp $src_apk $target_apk # 初始化渠道信息 empty_channel_file="META-INF/cztchannel_${target_channel}" # 寫入渠道信息 if [ ! -e $(dirname $empty_channel_file) ]; then mkdir -p $(dirname $empty_channel_file) fi touch $empty_channel_file jar -uvf $target_apk -C . $empty_channel_file done done

 python 腳本實現

 後記

目前的 v1 簽名機制下，對 meta-info 下的修改不會影響到 apk 簽名，可是在 Android 7.0 後提供了 v2 的簽名機制，這時候須要從新開發注入機制了，詳細請點我
