Android Recovery 复制大量预装apk步骤

Android Recovery 复制大量预装apk方法

方法二的实现：??
实现的位置在流程中见图片。?在install_package()的结尾的try_update_binary函数结尾();?在src/bootable/recovery/install.c?
?下面是具体实现：?
?//copy?some?res?file?to?/data/?
?static?char?*res_list[]?=?{?"/sdcard/?res1.zip",?"/sdcard/?res2.zip"};?
?static?void?unzip_res_to_data(void)?
{?????int?i?=?0;?
?????for(i?=?0;?i?<?sizeof(?res_list)/sizeof(char?*);?++i)?
????{?????????ZipArchive?zip_res;?
????????int?err?=?mzOpenZipArchive(?res_list[i],?&zip_res);?????????if?(err?!=?0)?{?
????????????LOGI("Can't?open?%s\n",??res_list[i]);?????????}?
????????else?{?????????????LOGI("start?update?%s\n",?res_list[i]);?
????????????//?To?create?a?consistent?system?image,?never?use?the?clock?for?timestamps.?????????????struct?utimbuf?timestamp?=?{?1217592000,?1217592000?};??//?8/1/2008?default?
????????????bool?success?=?mzExtractRecursive(&zip_res,?"res-private",?"/data/res-private",?????????????????????MZ_EXTRACT_FILES_ONLY,?&timestamp,?
????????????????????NULL,?NULL);?????????????LOGI("update?%s?%s\n",?res_list[i],?((success==true)?"success":"failed"));?
????????????mzCloseZipArchive(&zip_res);?????????}?
????}??
????dirSetHierarchyPermissions("/data/res-private",?1000,?1000,?0777,?0666);?}?
?//copy?some?app?file?to?/data/app?
void?cpfiles(){??
????ZipArchive?zip_apps;?????int?err?=?mzOpenZipArchive("/sdcard/myapps.zip",?&zip_apps);?
????if?(err?!=?0)?{?????????LOGI("Can't?open?%s\n",?"/sdcard/myapps.zip");?
????}?????else?{?
????????//here?need?fix?mount?for?your?device?????????if?(mount("/dev/block/mmcblk0p13",?"/data",?"ext4",?
????????????????????MS_NOATIME?|?MS_NODEV?|?MS_NODIRATIME,?"")?<?0)?{?????????????fprintf(stderr,?"%s:?failed?to?mount",?strerror(errno));?
????????}??
????????LOGI("start?update?3rd-apps\n");?????????//?To?create?a?consistent?system?image,?never?use?the?clock?for?timestamps.?

????????mzCloseZipArchive(&zip_apps);??
//cp?res?to?/data/?????????unzip_res_to_data();?
?????????scan_mounted_volumes();?
????????const?MountedVolume*?vol?=?find_mounted_volume_by_mount_point("/data");?????????if?(vol?==?NULL)?{?
????????????fprintf(stderr,?"unmount?of?%s?failed;?no?such?volume\n",?"/data");?????????}?else?{?
????????????unmount_mounted_volume(vol);?????????}?
????}??
}??
?//?If?the?package?contains?an?update?binary,?extract?it?and?run?it.?
