Java Question use of the serial libraries

[onair]

After a few months I finally managed to get a library that compiles correctly with B4A. But now I have another problem I keep getting this message from the android on which the program is installed:

** Activity (main) Create, isFirst = true **
main_activity_create (java line: 336)

I'm add B4A library, B4A project and the original Java library if someone has the time to help me where I'm wrong!

What is this library? Are you sure that it is compatible with Android?

 

[onair]

I do not know exactly, but the library was with the example that I received from the manufacturer

 

[onair]

In the meantime, I managed to root the device. Does that mean that they can now use Java object as a super user and thus access and setup the serial interface?

 

[Erel]

Rooting the device will not help. The first thing that you should find out is whether it is an Android library or not.

 

[onair]

Yes, is for sure Android library because it is part of a program written in Java and that nicely work on my Android computer. Unfortunately the whole ECLIPSE project is too large to send it to the forum. This is the only source in which is the main aćtivity, it should be the most important part of the project.

You can see an example of the library structure when there are so files: https://www.b4x.com/android/forum/threads/loading-so-library-files-error.54414/#post-341528

I am and tried everything, changed libs to lib, I adding additional folder. Practically everything what I read in the treads that are you recommended but nothing helps. After translating the SLC can not load libserialport.so. I can no longer trying this is the third month that can not solve this problem. If you can somehow help me to solve, help me, I'll probably give up. Just please no mysterious short sentences. I understand that you have a lot of work and you can not devote any problem a lot, especially if someone is a complete novice.

 

[Erel]

Building a library can be a difficult task. Especially if you are not familiar with Java.

You can make a post in the job offers forum.

Yeah, I guess you're right. I think I deserve help since I bought B4A, B4i and recommended a customer to buy B4A. But no matter, in any case, thanks for the reply.

regards.
