Aqui eu vou ensinar uma breve explicação do updater-script e pra quê cada comando serve, espero que vocês gostem! Vamos lá:
Veja um exemplo de um updater-script :
O objetivo desse comando é fazer uma instalação segura, Como por exemplo o script acima é do dispositivo GT-I9070, Esse comando vai verificar no build.prop do dispositivo se o modelo é o correspondente, Caso não for a instalação é abortada.
Esse comando monta a partição desejada, Para alterar algum arquivo você sempre têm quê montar a partição correspondente.
Esse comando extrai um arquivo específico para um específico diretório.
Esse comando é essencial, com ele você coloca as permissões corretas para cada arquivo.
Este comando executa scripts ".sh" ou binários como o busybox.
Esse comando faz o contrário do mount, Ou seja, ele desmonta a partição específica.
Esse comando formata uma partição específica, Exemplo, Eu quero formatar a partição system, Más eu tenho quê monta-la primeiro
Esse comando faz algo similar ao package_extract_file, Más ele extraí uma pasta para outra diretório.
Esse comando liga arquivos entre arquivos, como por exemplo o busybox quê está separado entre vários outros binários, Então esse comando "linka" os arquivos específicos para o funcionamento correto.
Esse comando faz o mesmo quê o set_perm, Más ele é usado para mudar as permissões de pastas.
Como o próprio nome já diz, Esse comando deleta arquivos específicos.
Mesma coisa do delete, só quê esse comando deleta pastas em vez de arquivos.
O comando ui_print é usado para dar observações de texto durante a instalação do arquivo.
Veja um exemplo de um updater-script :
1assert(getprop("ro.product.device") == "janice" || getprop("ro.build.product") == "janice" ||
2 getprop("ro.product.device") == "i9070" || getprop("ro.build.product") == "i9070" ||
3 getprop("ro.product.device") == "GT-I9070" || getprop("ro.build.product") == "GT-I9070");
