[GUIDA] Come creare un package update.zip

Verix · **Posted:** Mon Nov 15, 2010 11:47 am

Ciao,
come sapete in Android gli archivi zip particolari (che di solito vengono chiamati update.zip) che possono essere flashati usando l'opzione “Flash zip from sdcard” dopo aver avviato l'immagine di recovery.

Per creare un archivio del tipo "update.zip" con dentro gli aggiornamenti che volete rilasciare, basta fare così:
- creare una directory di lavoro vuota <workdir>
- creare la stessa struttura delle directory presente nel filesystem Android in funzione dei file che volete includere nell'archvio (es. <workdir>/system/app)
- copiate i vari files nelle directory (es. copiare test.apk in <workdir>/system/app)
- creare l'apposita directory per lo script update-script : <workdir>/META-INF/com/google/android
- creare ed editate il file <workdir>/META-INF/com/google/android/update-script aggiungendo le istruzioni necessarie per copiare i diversi file nel filesystem della ROM del telefono. Ad esempio, per copiare tutto il contenuto di /system/app, aggiungere:

Code:

show_progress 0.1 0
 
copy_dir PACKAGE:system SYSTEM:
set_perm_recursive 0 0 0755 0644 SYSTEM:app
show_progress 0.1 10

- assicurarsi di lasciare una riga vuota come ultima istruzioni dello script
- zippare il contenuto di <workdir> (es. chiamate l'archivio update-nosign.zip), includendo solo le sottodirectory di <workdir> ovvero senza includere il folder <workdir> medesimo
- fare il sign del pacchetto (java -classpath <SDK>/tools/sign/testsign.jar" testsign update-nosign.zip update.zip)

La sintassi dello script di update (update-script) è la seguente (XDA topic:***URLs are hidden from guests, please register and login to view the hyperlink***):

Quote:

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)

grazie Verix,
per creare un archivio update.zip, può risultare utile anche questo script (per windows): ***URLs are hidden from guests, please register and login to view the hyperlink***
