Android Tutorial 💡 Retrieving 2 JSON data feeds from an online server (Wear OS watch face) - Newer developers

Hello All
Here we have a simple example of how you use corwin42s WatchFace Library. The WatchFace library is extremely simple to use, corwin42 has done a great job wrapping it, thank you.

In this example we not only show the battery level, time and date using a custom font, but we also load JSON data from the internet to display information.

I'm not sure how long the JSON feed will stay up, it maybe only months or several years. So I've decided to download the 2 current JSON feed files and attached them to this post for future reference, just to be on the safe side.

Edit:
Removed LEDCoronavirus.zip - Original file (2 downstairs)
LEDCoronavirus_V1.0.0.1.zip - Optimised and removed unnecessary code, tidied up the Manifest.

Libraries needed:

Hello,
I can confirm that all you need are the libraries in the screenshot snip below. You need the WFManager from the link below.

@MikeFree STOP STOP STOP, you have gotten your post mixed up. Basically you are posting in the wrong thread.
The screenshots that you provided are for the original library tutorial by @corwin42 and is not for my tutorial in this thread.

You are in fact using the original code from the link below and not my code.
You should post a new question in the forum about your issue, but first read the instructions from the original post in the link below.

By the way, to FIX your issue above, you NEED to install ABExtDrawing library V1.7 from the link below.

Enjoy...

Hallo,

I try to compile in Debuggingmodus the Example LED Coronavirus. When the Compiler generate the R-File, i become this Errormessages:
c:\android\tools\..\extras\b4a_remote\androidx\constraintlayout\constraintlayout\2.0.4\unpacked-constraintlayout-2.0.4\res\values\values.xml:339: error: Attribute "android:alpha" has already been defined

Hello @bon,
Have you installed
1607002786691.png

via B4A SDK-Manager, it assembles perfect here????????

Make sure that you have the following

#Region Project Attributes
#ApplicationLabel: LED Corona
#VersionCode: 1
#VersionName: 1.0.0.1

'SupportedOrientations possible values: unspecified, landscape or portrait.
#SupportedOrientations: unspecified
#CanInstallToExternalStorage: False

#AdditionalRes: ..\resource

#AdditionalJar: androidx.wear:wear
#AdditionalJar: wearable-2.5.0.aar
#AdditionalJar: com.google.android.wearable:wearable, ReferenceOnly
#AdditionalJar: com.android.support:support-v4, ReferenceOnly
#AdditionalJar: com.android.support:percent, ReferenceOnly
#AdditionalJar: com.android.support:support-annotations, ReferenceOnly
#AdditionalJar: com.android.support:recyclerview-v7, ReferenceOnly

' Copy the wear app into the mobile app resource folder
'#CustomBuildAction: 4, C:\windows\system32\xcopy.exe, WatchfaceWear.apk ..\..\WatchfaceMobile\resource\raw\watchfacewear.apk /Y
#End Region

Don't forget to download and use the ABExtDrawing library too.

I don't think that I made any changed after the original post, I'll compare the above attached project with my current project later when I get the chance...
