B4A Library AwesomeSpeedometer

A wrap for this Github project. Posting
1. B4A sample project
2. B4A library files
3. Java code (I have been lazy - change it to your liking)
4. LibRes.zip - extract it and copy the folder into the B4A project so that it is on the same folder level as that of the /Files and /Objects folders of the B4A project.

I know this is an old thread, but I like the design of the gauge and downloaded the sample but still shows issue from this Post....am I missing something?
Open the designer, click on the Activity part of the layout to see the Activity properties and then rename the activity to whatever you want.

Hello
How to compile "The Java Code" ?
I want to modify some of the content inside.
Rebuild to generate JAR

With SimpleLibraryCompiler

Hi DonManfred

thanks for your reminder.
The jar has been generated with the SLC tool.
But I replaced the original "AwesomeSpeedometer jar" and there was a problem compiling.
Can you please guide me again Thank you.

You should always start a new thread for your questions.

OK

But I seem to solve this problem, it seems that there is a problem with the generated XML, compile OK after modifying the XML.
I will study it again. Thank you.

What are you using to compile the library with? Eclipse or SimpleLibraryCompiler?

Missed that one.....:)

Probably something to do with info entered into SLC. What is in -b4aignore? Can't remember if it was "main" or "com" or something else. Look at what the library package name starts with....
