Kalda's world

I have uploaded a “hotfix” version which fixes layout issues with Android 3.1 and later. On newer OS versions the classic radar images was not shown in protrait display orientation. So I introduced a new layout which is automatically activated on Android 2.1+ devices. This layout improve image zooming and scrolling. On 2.0 and older systems is the legacy mode activated and the application display images in old way. The version can be downloaded from the Google Android Market.

New version of CHMI application is out. Fixes many issues which leaded to activity crashes. Newly introduces 2×2 and 3×3 widget and satellite images of middle Europa. Widget is based on mobile weather radar pictures from www.chmi.cz which are updated each 30 minutes. In the settings menu can be optionally selected option to see bigger Europa satellite pictures instead of default detailed image which shows only Czech Republic. The apk is currently available on download page and after quick testing period will be released on the Market.

My 12 years old electronic music is now available to hear on this page. Unfortunately most tracks are missing now but I will try to find them in my archive. So if you like this old fashioned sounds please go directly to my MUSIC page .

This page and all resources including CHMI application resources are available using IPV6 protocol. I hope this will increase web page availability and also support the Internet future.

I made new release of my CHMI application. Newly with Google Maps View. Version is available on Google Market.

I have released the version 0.23 which changed data source from old.chmi.cz to portal.chmi.cz. This was necessary because the old page will stop working soon. In new version where removed 4 navigation buttons and replaced by scroll control. I have improved many places in source code and the new version seems to be much faster than the 0.22. I have also changed content of web view and the application now displays many informations faster and needs less data to download. At least weather forecast and flight informations are displayed much faster now. This is done by easy PHP based content proxy server installed on this site which transforms original CHMI site to small and easy to display site for web view of the application.

Next version will include Google Maps view mode, so please wait… Development and testing will take some time.

Old CHMI portal will probably shut down the old page version next month, so I have to release new version which uses data from the new portal. Some parts of old application where improved and rewritten. I made startup tunning and decreased time needed to display first image from 10 to 3 seconds on my G1 when using 3G data. Instead of old navigation buttons the SeekBar component is used. Full-screen mode is now available in the configuration options.

The new version will be released until 28.12.2010.

I had problem during uploading the current update of the CHMI application to the Android Market. I do always the same steps like 19x before but now i got following message from Android Marked during update upload:

The apk must be signed with at least one certificate in common with the previous version.

My keystore was not changed since last version and also the jarsigner -verify -verbose -certs –keystore my-release-key.keystore told me the apk is signed correctly with my keystore. But the apk was signed by two certificates. One of them was the right production certificate, but the second one was the debug certificate from my Eclipse build. This probably caused this very strange behavior of the Android Market. So I deleted *** the debug certificate from the apk and signed it again with my production certificate. And the update upload was successful.


***
So I removed the signatures by opening the apk file in Midnight Commander:
1] go to META-INF
2] delete files CERT.RSA, CERT.SF
3] in the MANIFEST.MF delete all line pairs

The source for all data of the CHMI application is portal www.chmi.cz. Because of an upgrade of this site the CHMI application stopped working on 4.10.2010. Old data are still available on address old.chmi.cz. I changed my application to use the old version of portal, but this is just temporary solution. So I will start writing the application from scratch to use new data source. You can download the fix version from my download site.

Since the old unerclocked Duron was too slow and apache2 was not able to handle all requests in acceptable time. I moved all stuff to a new machine with Atom CPU. The loading time is much better now. Intstead of 7 seconds server can display all pages under one second.
