A simple apk (tested and written on vf696 android 5.1 'phone) that includes daytime shower calendar.
Version h3 (v3 signature, cert md5: 8741357d4dd11e5c4a3ca328594fc8b8) 18th January 2023
This program requires a fast Android at least 800px400 screen.
to get the beacon list to work (and the bearings menu), change the line
https://www.keele.ac.uk/depts/por/50.htm to
https://www.qsl.net/zs1agx/por50.htm in the program's metrcal54/metrcal.set file.
(to find the location of metrcal54/metrcal.set , use the program's settings & other > System Information)
Another way to do this (that avoids file edit) is to download and save the por50.htm page and copy it into the same folder as metrcal.set
This apk stopped working on Android 5 and Android 6 Some years ago with a 'SSL java Trust Anchor Error' FIXED:
By installing a (self signed) ISRG Root X1 , it can work again for DJ4PK cluster and wspr.
[With this program, the Android UI 'back' button is more reliable with Android 5 than Android 6, Perhaps for Android 6, try tapping a blank
section of the screen before the UI 'back' button? But this could be because the test Android 6 is slower than the development Android 5?
For slower devices, especially in the satellite ground tracks screen, try holding the << or >> buttons down for longer?]
Installing a new Launcher 3 fixed the UI Back Button...
