Other How to convert code like this to b4a.

[LucaMs]

If some expert wants to be kind, when he has time ...

I have devoted little time even to Reflection. Sometimes I see that some develop wrappers for some Java libraries.

Can someone list the steps required to convert simple methods, no classes, from Java to B4A?

Like this: http://stackoverflow.com/questions/...-application-icon-programmatically-in-android

I wish something like:

a) create a new Java project in Eclipse;
b) add a new class;
c) add that method to the new class;
...

(I did not need to convert the code I linked - even if someone has this need - but I would like to understand how to proceed)

Many many thanks

If you don't know Java at all then it will be easier to use JavaObject to access these methods.

You will still need to understand the difference between a static method and an instance method.

Well, I knew the difference (there are also in VB.Net), but I forgot many things.

Static methods must be also in static class, or I'm wrong?

All I seem to have realized is that it is not difficult to access everything that is static, through JavaObject or Reflector.
This, however, when they are classes of Android; in the case that I have indicated, it is a method written by a user.
I suppose I should create a library (java), with that method declared static.

I realized: I have to start again to study Java, then JavaObject and Reflector.

I'm too old and with little brain ram, I could not.

Too bad.


Thanks Erel

I've got to get back into Java and then JavaObject for B4A too @LucaMs, I know exactly how you feel

+1: I feel like a left handed when I try to learn java. And I guess if we knew java we wouldn't use b4a and b4j too.

Well, do not worry: we will learn the next language / tool more useful in the future.
