Adding a splah screen to your webos app

With 1.4 you will see a instant opening of the application card in the background which might have a splashscreen and a separate icon on it. How is it done? Add this 2 lines to your appinfo.json:

“splashicon”: “icon-256×256.png”,

That was grabbed right from the calculator app. To see it you will need to restart Luna.

WebOS: MapTool 0.9.6 on PreCentral, Wikay 1.0.1 in the AppCatalog, Match This! Pro in the AppCatalog

I’m going to release MapTool 0.9.6 at in a couple of minutes. I fixed the offline map tile downloader: JTileDownloader to work correctly with longitudes < -90° and >90°. It was a small fix, but now the offline feature will also work for our American friends. Here is the forum thread about MapTool:

MapTool can now display old tracks, has a switch to enable/disable locking and can import .loc files. Also it works in connection with preCaching to load cache lists from Currently I’m working on .kml and .gpx import and will add a poor-man’s navigation mode. A global search is already implemented, just give it a try.

Download: JTileDownloader 0.5pre  JTileDownloader 0.5pre (221,0 KiB, 5.176 hits)

Now to something new in the AppCatalog: Wikay 1.0.1 has been released. Wikay is a smart mobile view on the Wikipedia’s startpage, supporting English and German Wikipedia. It’s available in the AppCatalog for 0.99$. Please, if you like, give it a try and if you did, why not rate it and write a comment in the AppCatalog.

At last I need to point you to ‘Match This! Pro’ also available in the AppCatalog. It’s a memory-kind of game where you play against your mobile device. The free version ‘Match This!’ already was highly rated by customers. ‘Match This! Pro’ gives you now some more options, more tile sets and will be continously updated. It’s available for only 0.99$ from the AppCatalog. If you want to give me a favor, buy it and rate it.

Preiswerte mobile Datenflat

Die wahrscheinlich preiswerteste Variante mobil immer Online zu sein, ist wohl das Internet-Packet M von O2 in Verbindung mit einem O2o-Vertrag. Mindestlaufzeit 3 Monate und 0€ Grundgebühr für den Vertrag + 8€ für die Internetflatrate. Hier der Link: (dabei bekomme ich ein paar Euro Provision pro Abschluss).

Frohes Neues Jahr,

MapTool 0.9.1 for WebOS

I created a new mapping application for WebOS called MapTool:

  • It displays maps from the OpenStreetMap project
  • shows your current position (and allows to send your position by email)
  • a selected target
  • direction and distance from your current position to the target
  • your current track (and can send it as gpx file by email)
  • the real ground elevation at your current position and also
  • allows the use of offline maps.

Offline maps can be created using this adapted Java tool from here: Tool for offline download: here
The offline maps are a couple of PNG files which has to be in a folder called .MapTool (the leading dot is important!) on the internal volume of your WebOS device. Just use the tool to download the tiles and copy them into the freshly created .MapTool folder after connecting the Pré as USB drive to your desktop computer.

If you want you can replace some of the maps with your own, but ensure you use the same naming, bounding box and image size as the OpenStreetMap project for its tiles.

The official thread about it, is here:

Some general usage infos:

Start the app, it will try to get your position using GPS. In same cases it will take some time to get your position, then it might just use a rough assumption. You can see the error of your position location in the bottom info strip.

The app will just starting logging your position, you can see your track in blue and in the bottom strip also the ID of your track (date + time of the starting point).

The app follows your position and downloads OSM tiles whenever necessary, use + and – to zoom in or out. Use the reload button to have it refresh the map tiles in case something went wrong. When you start moving the map, it will release the connection to your current position and the zoom-level display will display “move”. Click on it to access the list of targets or to jump back to your current position.

Use the send button to send your current location or the current track by email.

Use the menu to access the settings. Here you can switch the different OSM renderers (use the refresh button to reload the tiles). Also you can specify the error level which will used to draw your path or to convert the log into gpx. A good value is below 100 meters (sorry for only supporting metric units).

The bottom strip also shows you the altitude which the GPS reports and the elevation of the ground as it is stored in the NASA database. Therefore MapTool asks about the elevation value every 10 seconds. It will be adjustable in a later update.

Also I’m glad to announce the appearing of OGCOpenInfo in the official AppCatalog. A very handy tool for all passionate “The Open Golf Challenge” players.

Some findings on WebOS

Auto text-correction in WebOs is at least in German not always very smart. One could wish to disable it:

Pick up your WebOSQuickInstall app and change in
the value at

To examine is still if /etc/palm/browser-app.conf contains the value to cache webpages.

Another patch is to show the state of the mute switch:

or a patch for fast toggle between GMS (2G) and UMTS (3G)
