手動製作update.zip包的過程：1.建立一個update目錄，該目錄包含自己想要升級或替換的內容例如：update/update/systemupdate/system/appupdate/system/app/doodle_jump.apkupdate/META-INFupdate/META-INF/comupdate/META-INF/com/googleupdate/META-INF/com/google/androidupdate/META-INF/com/google/android/update-script該目錄包含doodle_jump遊戲，升級後該apk將出現在手機的/system/app/目錄下。META-INF目錄下包含升級指令碼，update-script指令碼的內容如下：show_progress 0.500000 0copy_dir PACKAGE:system SYSTEM:show_progress 0.100000 0大家可以根據自己的升級內容添加相應的命令。2.建立壓縮包在update/目錄下運行：$ zip -qry ../update.unsigned.zip ./將在update/的父目錄下產生update.unsigned.zip 壓縮包3.簽名$ java -Xmx512m -jar signapk.jar -w key.x509.pem key.pk8 update.unsigned.zip update.zip產生簽過名的update.zip包，其中signapk.jar，key.x509.pem，key.pk8與具體手機系統相關4.將簽過名的update.zip包放入手機sdcard根目錄，
重啟系統進入recovery模式，選擇apply update.zip，成功後重啟手機ok，現在手機上已經有doodle_jump遊戲了，並且它無法被刪除～refer:

to Create Android Update Zip PackageThere are several ways to install applications or library files to an Android Phone.
You can use Market application to find and install or adb command
line tool to install or push the files to Android file system. These are all easy to implement for single file but if you have several applications or library files to install at once, it might be better to use update zip file. The update
zip file is Android advanced system to install applications or lib files to Android file system using recovery tool. This method is commonly used by rom or theme developers to distribute their package. Creating an update zip file is quite easy, all you have to do is put the files in corresponding directory in Android file system and an update-script file to copy the files. For example, to install Calculator.apk into system/app and
copy libsec-ril.so file into system/lib :
- Create an empty folder (eg. C:\myupdate)
- Create C:\myupdate\system\app folder for Calculator.apk and C:\myupdate\system\lib folder for libsec-ril.so
- Create C:\myupdate\META-INF\com\google\android folder for update-script file.
- Create the update-script file with the following syntax:
show_progress 0.1 0copy_dir PACKAGE:system SYSTEM:show_progress 0.1 10 Line 1&5 : show progress bar
Line 3: copy system folder from update package to Android’s /system Note: you should add one extra line at the end of the file (Line 6)
- Compress the entire contents of C:\myupdate folder to zip (not the myupdate folder itself)
- Sign the myupdate.zip file
java -jar signapk.jar certificate.pem key.pk8 myupdate.zip update.zip Note: you can find tutorial on how to sign the update.zip file here
- Copy the update.zip file to sdcard and apply it from recovery console
update-script syntax reference (definitions from recovery.c android source code):
- copy_dir
Syntax: copy_dir <src-dir> <dst-dir> [<timestamp>]
Copy the contents of <src-dir> to <dst-dir>. The original contents of <dst-dir> are preserved unless something in <src-dir> overwrote them.
Ex: copy_dir PACKAGE:system SYSTEM:
- format
Syntax: format <root>
Format a partiti0n
Ex: format SYSTEM:, will format entire /system . Note: formatting erases data irreversibly.
- delete
Syntax: delete <file1> [... <fileN>]
Delete file.
EX: delete SYSTEM:app/Calculator.apk, will delete Calculator.apk from system/app directory.
- delete_recursive
Syntax: delete_recursive <file-or-dir1> [... <file-or-dirN>]
Delete a file or directory with all of it’s contents recursively
Ex: delete_recursive DATA:dalvik-cache, will delete /data/dalvik-cache directory with all of it’s contents
- run_program
Syntax: run_program <program-file> [<args> ...]
Run an external program included in the update package.
Ex: run_program PACKAGE:install_busybox.sh, will run install_busybox.sh script (shell command) included in the update package.
- set_perm
Syntax: set_perm <uid> <gid> <mode> <path> [... <pathN>]
Set ownership and permission of single file or entire directory trees, like ‘chmod’, ‘chown’, and ‘chgrp’ all in one
Ex: set_perm 0 2000 0550 SYSTEM:etc/init.goldfish.sh
- set_perm_recursive
Syntax: set_perm_recursive <uid> <gid> <dir-mode> <file-moe> <path> [... <pathN>]
Set ownership and permission of a directory with all of it’s contents recursively Ex: set_perm_recursive 0 0 0755 0644 SYSTEM:app
- show_progress
Syntax: show_progress <fraction> <duration>
Use of the on-screen progress meter for the next operation, automatically advancing the meter over <duration> seconds (or more rapidly if the actual rate of progress can be determined).
Ex: show_progress 0.1 0
- symlink
Syntax: symlink <link-target> <link-path> Create a symlink (like ‘ln-s’). The <link-path> is in root:path format, but <link-target> is
for the target filesystem (and may be relative)
----------用Android內建的signapk.jar + .x509.pem + .pk8簽名應用程式
http://lmdy2001.blog.163.com/blog/static/8423891020114262323816/ 檔案位置：可以在platform/build/target/product/security/中找到platform.pk8 platform.x509.pem等簽名檔案，對應不同的許可權。
signapk.jar：由/platform/build/tools/signapk/編譯產出,可以在/out/host/linux-x86/framework/中找到。簽名：
java -jar signapk.jar platform.x509.pem platform.pk8 MyDemo.apk MyDemo_signed.apk 得到具有對應許可權的APK 最佳化APK：
zipalign -v 4 MyDemo_signed.apk MyDemo_new.apk 查循APK是否最佳化過：
zipalign -c -v 4 MyDemo.apk 原文轉自：http://www.blogjava.net/MEYE/articles/357111.html |
