Android applications

Showing charging / discharging current to the battery on an analog instrument.
The analog display of charging current makes it easier to find the optimal location of the phone on wireless chargers.

Do you want a soft-boiled egg or make tea or...

Then help is here! These timers require absolutely minimal operation: Open the phone, tap a timer, and the rooster will crow when the time is up. The app closes itself, of course. Connoisseurs can adjust the time with a long press.

IGC files are included for training purposes, and you can put your own IGC files in sdcard/Gliding/IGC/. https://play.google.com/store/apps/details?id=dk.johny.gliding.activity
This app can also receive test data via WIFI from the IgcReplay program, so you can practice the use of Gliding while waiting for better weather.
This is mostly usefull, if you have a lot of IGC files you would like to test.
You can see how to send IGC files via WIFI here: https://www.johny.dk/Videos/IgcReplay_wifi.mp4

THE WAR WITH GOOGLE PLAY CONTINUES. I have the impression that Google Play is now intensifying their personal war against me and my apps. The first time you start Gliding, they now show a message that the Gliding app uses full screen, and you have to accept this to continue with Gliding. The problem is that this message is displayed so briefly that you can't even read it, after which it is covered by the Gliding startup image. This is a deadlock situation because Gliding is not allowed to continue until you press ok in the pop-up window, which you can't, since it is no longer visible. The only way out I know of is to reboot the phone and start Gliding again, and be really quick to approve that Gliding can run full screen. I don't think even Trump could have come up with a better way to annoy the world.

Update: Google won. I have removed all my apps from Google Play.

Calculator for entering flight times in your logbook and the plane's journal.
https://www.johny.dk/Android/FlightCalc.apk

Try it! You have never been able to count hours and minutes with so few key clicks.

You can add these numbers together without any keystrokes if you use mental arithmetic. BUT IT DOESN'T WORK ERROR-FREE !!!

Fif: If you hold the phone horizontally, there is room for even big fumble fingers.

Speedometer for winch drivers at Kaldred.

See how strong a signal is being received from the aircraft. Also shows the difference signal during the start, but it is recommended to use the LedDisplay for that. The app starts when the winch engine is switched on. However, must be connected with a USB cable.

Log files from the winch starts are generated in /sdcard/WinchSpeed/

To work most easily, remove opening ceremonies such as swipe, PIN, face or fingerprint so that the phone just starts when you turn it on. So do not use your normal phone, or at least not without having it under surveillance. It will also be a bit critical to forget the phone somewhere if you turn off the start lock.

In addition, in the phone's developer settings enable "Avoid hibernation while charging".

You can use the phone with start lock, but then you have to turn on the phone yourself every time before turning on the ignition.

Widget to turn mobile data and hotspot on and off.
https://www.johny.dk/Android/wwwToggle.apk

Due to some change in Android, this widget stops working quite often, so it is probably faster to yourself making the changes in the settings for hotspot and mobile data.

If it stops working, delete it (do not uninstall) and re-insert it. Annoying.

I work from time to time on the case, but it is not easy when Android does not behave as described in the documentation. I think it has something to do with the fact that a limit of 50 has been introduced for things that do nothing. So my widget just gets dumped. Imagine if the same thing happened to all the app icons that do nothing !!!
