如果要修改0719后的CM系统apk,可以用这个证书签名,不需用存储替换的方法.
附CM系统apk列表(其它apk不要用这个证书签名,不然装不上.):
/system/framework/framework-res.apk
/system/app/AccountAndSyncSettings.apk
/system/app/CertInstaller.apk
/system/app/CMParts.apk
/system/app/CMScreenshot.apk
/system/app/DefaultContainerService.apk
/system/app/LiveWallpapersPicker.apk
/system/app/PackageInstaller.apk
/system/app/Pacman.apk
/system/app/Provision.apk
/system/app/SettingsProvider.apk
/system/app/Settings.apk
