Features

Geolocation detection
Map caching
Search
Organization cards
Building a route

MIDP 2.0
JSR-75
A lot of RAM
A lot of space in persistent memory
JSR-179 (optional)
HTTPS support (optional)

Recommended system tweaks

On symbian 9.x, it's recommended to install a patch to allow access to file system without confirmation popups.

How to make geolocation work?

On Symbian 9.x / ^3 disable all location sources except unassisted GPS.
Disable A-GPS. On non-symbian devices it may be called as "geolocation server", "internet support", "supplement server" or something like that.
Let your device perform a cold start: request geolocation in any app (MahoMaps, Google Maps, Ovi Maps, Sports tracker, anything else) and keep the device under clear sky. It is desirable that the horizon is visible. Wait until it catches sattelites. May take a while.
Once you are sure that GPS receiver works okay, you may try to enable A-GPS to increase accuracy and startup time. We recommend using supl.google.com as supplement server. supl.nokia.com is dead!
If you experience issues, try disabling A-GPS.
If you device can't catch sattelites even in good weather, check that its GPS receiver is operable.

Tested systems

Symbian ^3/Anna/Belle/Refresh/FP1/FP2
Symbian 9.2-9.4
Bada 1.1

Supported emulators

Build without IDE

Github actions

We have an action which builds the app on git pushes. You can pull latest builds from it, check "checks" section of your pull request or commit info.

Windows

Install an SDK for your device, follow its instructions.

Debian / Ubuntu

dpkg --add-architecture i386
apt update
apt-get install gcc-multilib libxt6:i386

Then install 32-bit JDK 1.6.0 and WTK 2.5.2. Edit build script to use your installed tools (instead of "compiler" repo clone) and run it.

Adding your own localisation

Create copy of en.txt/ru.txt, name it with your language's code and translate all strings.
Keep in mind that original language of app was russian (russian is original. Not english).
You can test how it will look like with replacing english file, for example.
To make it actually work as one more language, you need to make 3 changes in app's code:

Go to Settings.java. In GetUiLangFile() add one more case (with next number) to the switch. Make it return name of your file without .txt.
Startup selection: MahoMapsApp.java, processFirstLaunch(). Add your language to lang choice group. Name it in english (Russian, not Русский).
Settings menu: SettingsScreen.java, ChoiceGroup uiLang. Add your language. Name it as is (Русский, not Russian).

CI on your pull request will attempt to compile the project. If you failed somewhere, it will show that.

mm-v1's Issues

Route creation makes extra file system access

Убрать дебажный дамп, создает дополнительный запрос разрешения

Make CI produce special builds for devices without JSRs

Геолокация, NokiaUI и т.д. Нмания делает похожую вещь, основную логику можно скопипастить оттуда.

Keep screen on while route navigation is active

This is critical for "by car" use case

App crashes without error on search

https://4pda.to/forum/index.php?showtopic=1070499&view=findpost&p=125999077
Platform: Belle FP2 (Nokia 808)

Automatically refresh token if expired

Every day I need to manually refresh my token because it's always expired.

Add vibration on establishing gps connection

Since cold start takes a random amount of time it's good to know when the phone is ready

Load more tiles at the same time (async or something)

Add shortcut for showing/hiding coordinates and geo status

It would be useful to change geo popup setting on the go using one of the numeric keys

-> only marker on the map -> marker and status -> marker, status and coordinates ->

Compiliing from sources

How to compile u'r project from sources? Is jdk for x64 or x32? Please, add manual for compiling from sources

Application icon is too big and cropped on Symbian 9.1

OS: Symbian 9.1
Phone: Nokia N95 8GB

Discussed in #27

Не работают сетевые функции, нужны правки в коде для добавки порта :80 к HTTP запросам

Use nnjson instead of org.json.me

just a suggestion, low prio

Add rms cleanup in settings

Add option to clean up the rms storage from application settings menu

Change zoom keys to * and #

More convenient way to zoom on 12 button keyboards. Same keys used in ovi maps.

Key holding is too slow on S40

Add zoom with volume keys support

Map canvas flickers in KEmulator through lcdui menus

Repaint loop somehow ignores if (MahoMapsApp.paused || hidden) { if (rt == null) { branch.

Obviously because hidden was not set because hideNotify somehow did not fire. Happened only once.

Add setting to change proxy address

Drop icon256

Используется только в экране "О". Жирно.

Too large control buttons on Nokia Asha 310

Panel with 50*50:

Panel with 30*30:

I think we need one more parameter - something like 40x40, because 50x50 is too large and 30x30 is too small

Make route thickness depend on map zoom

Add telemetry for about/others screens

Я говорил что не будет, но нет, будет. Я хочу знать открывает ли вообще кто-то эти 2 экрана, или они так, для красоты у нас.

Add language choice on startup

Надо было сделать ещё в 1.1.0, но всё как обычно.

Does not work through cellular on Blackberry

Please add a dialog window to choose between Wi-Fi and cellular network at app first start and an option to change it later in the app's settings. At the moment, the app tries to connect through Wi-Fi and crashes with "the required radio is not active" error. Wi-Fi adapter is disabled in Russian version of Blackberry 9520.

`GeoUpdateThread.<clinit>` is unsafe

This works only because all tested JVMs follow https://docs.oracle.com/javase/specs/jvms/se7/html/jvms-5.html#jvms-5.5 and call <clinit> only when the class is actually used. This happens when user requests geolocation from map screen. At this point, LoadLocale() is guaranteed to be called. Otherwise, you will get something like

java.lang.ExceptionInInitializerError
	at mahomaps.MahoMapsApp.<clinit>(MahoMapsApp.java:73)
	at java.lang.Class.forName0(Native Method)
	at java.lang.Class.forName(Class.java:348)
	at emulator.Emulator.main(A:955)
Caused by: java.lang.NullPointerException
	at mahomaps.map.GeoUpdateThread.<clinit>(GeoUpdateThread.java:153)
	... 4 more

While this will be the case only on VERY broken custom jvms, this is still bad due to being one of blockers to support dynamic language switch. That array should hold only numbers of texts, not texts themselves.

Add motorolla key layout

It's different from Nokia/SE.
