This may have been answered elsewhere I thing about zip files.
But is there a way to manually install a custom arduino library. I see libraries are stored in arduino15 directory but not sure how to set it up so if a copy a lib to that location a sketch will see it?
If not really need a way to do it! Applab improvement?
Part of the answer is on Arduino App Lab Libraries Upload . I am working to document my experience with using custom library, but I can already tell you.. it is nothing like the Arduino IDE experience.
User libraries are NOT stored under Arduino15, they are located in the libraries folder under the User Sketch folder.
Where???
I have a quick and dirty sketch to display stuff on Adafruit LED matrix...
It uses 3 Adafruit libraries, as you can see in the Libraries...
However if I use an Linux Command prompt, and look for any files in this project
that has the name Adafruit...

The cache has the compiled binaries for these libraries, but I don't see the
sources.
However if I search the whole user directory, I see:

Looks like the Source files are stored in the ~/.arduino15/internal directory.
That's all new to me and Arduino15 is not the same as .arduino15 a hidden file.
Thanks thought I saw something about that but forgot where. I tried the method in Arduino App Lab Libraries Upload - Development Tools / App Lab - Arduino Forum and worked like a charm.
Yeah I had tried to put the lib in that directory and link it in the yaml but it doesn’t see it so something else more complicated is needed. Wish there was an automatic way to do. However, using WinSCP (the link you gave me) makes it a lot easier to copy things instead of using adb push/pull method.
The libraries added with App Lab are downloaded from github and installed in .arduino15/internal directory. But they need to be installed. Unzip a library here is not enough to use it in sketches. And that way you can’t add custom libraries not on github.
The only option I have found is to add them in: .arduino15/packages/arduino/hardware/zephyr/0.x/libraries but they will be lost at each update.
My choice is to put all the libraries I want to use in my sketches in a dedicated directory (I use /home/arduino/Arduino/mylibs) and make a symbolic link (ls -s source_library_path reference_library_path) for each in zephyr libraries above.
I list the libraries in a text file and I have written a bash script that read each line and make the lien. So I just need to rerun the script after a zephyr update.
The script:
#!/bin/bash
if [ "$#" -ne 1 ] ; then
echo syntax error: addLibs libraries_name
exit
fi
filename=$1
referencePath="/home/arduino/.arduino15/packages/arduino/hardware/zephyr/0.52.0/
libraries"
sourcePath="/home/arduino/Arduino/mylibs"
while IFS= read -r line; do
ln -s $sourcePath/$line $referencePath/$line
done < $filename
Like the approach as another option to add local libraries.
I use several libraries I have written on most of my sketches and it’s the only way I have found to add them.
I suggest as an App Lab improvement to search also libraries in ArduinoApps/libraries.
I fully agree the Arduino App Lab should be improved for the library search and include the local libraries.
The active Arduino community so far has delivered 4 options to deal with this in meantime. I am trying to document them, each with their advantages and disadvantages
Maybe slightly off this topic, but another question I have about libraries is, what happens, when I library I have installed/used/Add is updated?
For example one of my apps is currently using Adafruit GFX. If I look in the
.arduino15 library I see that the directory containing it is named: Adafruit_GFX_Library_1.12.4_3344e7ed2124dbaf
Which I am assuming is version 1.12.4 and probably a hashtag...
Which also matches what is in the sketch.yaml file.
Now suppose Adafruit releases a new version of the library? What happens?
Is there any notification of this? Will it automatically update my current projects using the older version? If not how do I do it?
If I edit a local copy of a library, when I try to use that library does it check hashtags?
(My guess is not, but...)
If I create a new project and click to add it, does it use my currently installed one or
does it download the current one? And link to it? Or continue to use the one that was downloaded for earlier project?
...
Thats kind of what I am assuming as well.
Think it is going to use whatever is in ./arduino/internal at the time. At least that is what I assuming since it seems like it copies from that directory into the app directory, i.e., cache libraries.
Actually what I think will occur. If you have adfuitGfx 1.12 as a downloaded library and a custom version that you reference in the sketch.yaml file as you as you dont include the library via add libraries Applab wont use the one you downloaded
