Android Question [PROBLEM FOUND] Errors after change Http for OkHttp

[Walter Adriano da Silva]

Hello

Once I changed HttpUtils2 with Http to OkHttp the application began to show some errors that were not displayed.

Errors like:

(Line: 145) If Not(res.EqualsIgnoreCase("1")) Then
java.lang.NullPointerException

"res" is the result from a Single Result Query.

I think that maybe the change from one library to another isn't the cause for this, but the errors started just after that I made the change.

Note: If I try use res in log, it's shown normally

 

[Erel]

Is this the full error message?

 

[Walter Adriano da Silva]

Yeah, just it.

 

[Erel]

It looks like a debugging issue. Test it in release mode and see whether it happens.

 

[Walter Adriano da Silva]

I just test
The app stopped at same moment that debug mode

 

[Erel]

Can you upload your project (File - Export as zip)?

 

[Walter Adriano da Silva]

Sorry, I can't
Do you would have another way to check this?

 

[Walter Adriano da Silva]

If I catch this error on try/catch other error is thrown

An error occurred:
(Line: 160) If res <> 1 Then
java.lang.OutOfMemoryError: Java heap space

This is the full message too. It's the same variable in other place.

 

[Erel]

Can you send me the project by mail?

 

[Walter Adriano da Silva]

I need a permission for this.
For while I'm using the apache-based http library again and the app works now.

 

[Walter Adriano da Silva]

Project sent by mail.

The problem here was incompatibility between OkHttp and Picasso Lib to B4A.

When I pass the URL directly to browser, it work fine.
So, could you tell me what is the problem ?

Looking forward to hearing from you soon.

Looking forward to hearing from you soon.

1. You should start a new thread for your question
2. You should provide more information. Example project which shows the problem.
