Java Question .:Create Basic4Android Libraries:.

[Acuario]

- For the XML File:

In Eclipse, go to Project > Generate Javadoc. Again a new window will popup saying “Generate Javadoc.” In javadoc command: locate your javadoc.exe. mine is: C:\Program Files (x86)\Java\jdk1.6.0_21\bin\javadoc.exe. Make sure you select the right one and don’t just copy mine.
Next check the checkbox next to the library you want to convert. Visibility: public and select the radiobutton saying: use custom doclet. Doclet Name: “B4ADoclet” and Doclet class path: “C:\Program Files (x86)\Anywhere Software\Doclet“ both without the quotes. Remember that the path may be different from yours.

B4ADoclet should be BADoclet !!

I. Introduction.

import anywheresoftware.b4a.BA.Author;
import anywheresoftware.b4a.BA.Permissions;
import anywheresoftware.b4a.BA.ShortName;
import anywheresoftware.b4a.BA.Version;

XverhelstX

Can you tell me why you use "anywheresoftware.b4a." in the above import statements? Where does this info come from and what should I use in my library code? When I try the above, Eclipse flags errors and will not make the .xml; files.

 

[Erel]

Please do not post duplicate questions.

How come on this tutorial you use

import anywheresoftware.b4a.BA.Author;
import anywheresoftware.b4a.BA.Permissions;
import anywheresoftware.b4a.BA.ShortName;
import anywheresoftware.b4a.BA.Version;

but on Erel's he doesn't?

Just confusing me a little. Needed or not?

Cheers

 

[Erel]

These imports are needed. However Eclipse will add them automatically if you use the auto-complete feature (Ctrl + Space).

 

[barx]

I must have done something to Eclipse. All I tried to do was add a new (2nd) project and now whenever I right-click on the project name and go to build path the only option I get is 'Configure Build Path'.

Any ideas what I have done. lol

Turning Speexdroid into b4a lib

Hello!

I wanted to turn the Speexdroid lib into a b4a lib.
I am not sure if I can/should follow the instructions here, or if I need to start differently.

I have downloaded the trunk from
speexdroid - Revision 22: /trunk
using Tortoise svn.

I have then opened up Eclipse and chose "File->Import...".
I selected "General"->"Existing Projects into Workspace".

This worked fine so far, except a red exclamation mark on "Vbr.java".

Could anybody please give me a push into the right direction?
I am not sure what should be done next.

Thank you very much!

Library Wrapper - proper tutorial

I'll echo the request for Speexdroid lib (or ANY) library. I've created B4a libraries without any problem, but can't seem to find a simple example that show a simple jar file being 'wrapped' although I have seen several requests for this info and YES I've seen the library creation tutorials and the ADMOB reference and I'm still not getting it. So a simple jar file with a couple of classes and the code for the wrapper and the (static read only XML?) and an example invocation from B4A? Pretty please
-Thanks

 

[netchicken]

Whoa, that's exactly why I was reading this thread. Someone asked me that after they created the jar, how did they get it to become an accessible library in B4A. A paint by numbers instruction tutorial for people not versed in xml or whatever needs done would be excellent.

You should create a regular library and add an annotation such as:

@DependsOn(values={"libGoogleAnalytics"})

In Eclipse your project should reference the other jar file.
This will tell the B4A IDE to add a reference to the other jar file (which should be located in the same folder).

Hi .
I have one problem with one class of my library.
Inside of eclipse the class work fine but when i put in the b4a the class doesn´t work. what Can I do to resolve?
I didn´t use any @return or @param
I have Try Catch
But I really doesn´t understood what was happen.
How Can i debbug this?
Because I only tried Do
Dim test as XMLPodCast
I try run the b4a stop.

 

[Erel]

What do you mean that it doesn't work? Is there any error message? Have you checked the logs?

Note that it is better to start a new thread when posting a question.

Problem generating jar file with ported java library

Hello,

I am trying to port a java library that has many classes. After painfully annotating all classes with the @Shortname("someclass") for all classes,
I followed the Doclet commands given in the video tutorial for generating the xml and .jar files. The procedure only generates the xml file, not the jar file. What am I doing wrong ? Please help. Where is my jar file ?

Thank You

Thank you for sharing your knowledge.

You will need to first download the custom Doclet from this tutorial: http://www.b4x.com/forum/additional...es/6810-creating-libraries-basic4android.html

Working inside C:\Program Files may cause all kinds of permissions problems. Usually it is better to work in some other path.

 

[thedesolatesoul]

To export the JAR file, go to File>Export>JAR

After painfully annotating all classes with the @Shortname("someclass") for all classes,

You do not need to annotate all classes. You only need to annotate the classes that you want to expose.
