Third-party libraries

Mateja · April 6, 2020, 9:23am

Hi,
Is it possible to import other third-party libraries to an extension?

the log does say that the package does not exist

Is there any way to “install” these kind of libraries?
Thanks.

Sorry, I thought you were talking about Kodular Extension IDE…

Mateja · April 6, 2020, 9:35am

http://ide.kodular.io/ has been down for months.

Yes it is possible.
This is what you are looking for:

So,
How shall I import it?
This doesn’t work:
@UsesLibraries(libraries = "Twilio.jar")https://github.com/twilio/twilio-java/blob/master/src/main/java/com/twilio/Twilio.java

Sometimes you have to use @UsesLibraries annotation.
Most of the time this will work:

Copy jar file to <root>\appinventor-sources-master\appinventor\lib\JarFolder
(Create JarFolder dir in case it does not exists)

Add this line to <root>\appinventor-sources-master\appinventor\components\build.xml:

<copy toFile="${public.deps.dir}/NameOfJar.jar" file="${lib.dir}/JarFolder/NameOfJar.jar" />

I am using the AppyBuilder IDE. Is it possible there?

vknow360 · April 6, 2020, 10:52am

No it is not possible there.
You can try this template:

It is very lightweight (just 25 mb) , fast and easy to use.

Did it with the Kio4 tutorial. Now I just import it normally (like this)?

You see I’m pushing to get that and the store fixed, but Congress won’t approve the bill

Anyone familiar with this error?

BUILD FAILED
C:\Users\ONT Studios\appinventor-sources\appinventor\build.xml:44: The following error occurred while executing this line:
C:\Users\ONT Studios\appinventor-sources\appinventor\components\build.xml:2: Unexpected element "{}copy" {antlib:org.apache.tools.ant}copy

My build.xml It’s exactly the same as on GitHub

vknow360 · April 6, 2020, 1:13pm

I think you have posted wrong build.xml file.
You should post <root>\appinventor-sources-master\appinventor\components\build.xml but you have posted <root>\appinventor-sources-master\appinventor\build.xml

Mateja · April 6, 2020, 1:14pm

Right, the first error was the one.
(probably an error with the twilio import)

Try this one:

Mateja · April 6, 2020, 1:24pm

Yes, but it doesn’t have the Twilio library.

vknow360 · April 6, 2020, 1:26pm

Are you sure that you have Twillo.jar file in JarFolder directory or you just have copy-pasted?

Mateja · April 6, 2020, 1:28pm

EDIT: Just noticed that it requires a .jar, not .java file.

vknow360 · April 6, 2020, 1:29pm

You have to put jar file not java file.

Mateja · April 6, 2020, 1:29pm

Would just renaming the file extension work?

vknow360 · April 6, 2020, 1:30pm

No,not at all.
Java and Jar are quite different.
Java is raw version while jar is compiled version.
Search jar file on google and put there.
