tzupdater's Issues

Update tzdata for android 10 and higher

For android 10 and higher tzdata should be replaced in /system/apex/com.android.tzdata/etc/tz/ too

in my phone (xiaomi mi 9 se *android 11) after running update in the app and reboot nothing changed, by copying tzdata from /data/misc/zoneinfo/tzdata to /system/apex/com.android.tzdata/etc/tz/ and /system/usr/share/zoneinfo/ timezone data get updated.

Systemless mode

Bro can you add support of systemless mode? Magisk module. Directly app can't patch my device

Wrong time zone even after updated to the latest version

Hi,
I updated my tablet timezone (Lenovo Tab3 10 with Android 6) successfully with your application (Timezone Updater 1.3.0) to 2023c. Now it shows the current timezone as 04:30. It is wrong. The Iran government decided not to change the time anymore this year.
I saw that you used https://www.iana.org/time-zones/ to update the timezone. I thought it could be something wrong with this website database. I contacted them and they said that they changed the Iran timezone in 2022b, released 2022-08-10: https://mm.icann.org/pipermail/tz-announce/2022-August/000071.html So their database is up to date. They said that I should contact you as you are the application developer.
The Iran timezone is 03:30 now and did not and will not change.
Please take a look at it.
Thanks a lot

[1.0.3-19]Unable to get tzdata

Log included
tzupdater.log
Update: looks like a busybox bug, also busybox from the neighbourhood said, that it's updated, but tzupdater is using the old one.

tzdata 404 not found error

tzupdater/app/src/main/assets/all/bin/tzdata-updater.sh

Line 41 in 7ec6253

TZ_VERSION=$(wget -q -O - "http://data.iana.org/time-zones/" | grep -o '[0-9]\{4\}[a-z]\{1\}' | sort -u | tail -n1)

Thank you for this necessary program. I have been using it for years now. I found a little problem. The program is trying to download tzdata8675a.tar.gz leading to a "404 Not Found" error.

This code currently returns the wrong data:
wget -q -O - "http://data.iana.org/time-zones/" | grep -o '[0-9]\{4\}[a-z]\{1\}' | sort -u

Failure to update icudt58l

The update fails with the following error:

icupkg: not an ICU data file: "/data/user/0/ru.meefik.tzupdater/files/tmp/zoneinfo64.res"

I'm using Blackview BV9500 Pro, Android 8.1.

Data getting issue

App can't get latest data. Tried with VPN too

wget: bad address 'data.iana.org' fail

when I click on the update button, get this error:

>>> TIME ZONE DATABASE
Getting latest version ... wget: bad address 'data.iana.org'
fail
An error has occurred. Exiting.
.
>>> ICU DATA
Getting latest version ... wget: bad address 'api.github.com'

Explain build process

Could you explain the build process a little more, e.g. if I want to build it completely from source, which steps have to be executed in which order?

Also build-dex.sh is referencing $HOME, but shouldn't be that somewhat linked to ANDROID_HOME instead?

icupkg: .res format version 03.00 not supported

Timezone Updater 1.0.3
Android 8.1.0
Updating ICU data now fails with the following error:

+ printf 'Updating icudt58l.dat ... '
Updating icudt58l.dat ... + icupkg -s /data/user/0/ru.meefik.tzupdater/files/tmp -a zoneinfo64.res /system/usr/icu/icudt58l.dat
icupkg: .res format version 03.00 not supported, or bundle malformed
+ '[' 16 -eq 0 ']'
+ printf 'fail\n'
fail
+ return 1
+ restore

According to users on the forum http://4pda.ru/forum/index.php?showtopic=692805&st=60 the issue seems to be an out-of-date icupkg package.
Thanks for your work on this most helpful program!
