Is this the error code you get? It will help others to diagnose the problem.

Notice: If you use OKHttpUtils Library version 2.82 it will not crash.

Your answer is wrong. it has nothing to do with httputils library.

Add the following to the manifest

AddApplicationText(
<uses-library
      android:name="org.apache.http.legacy"
      android:required="false" />
)

thanks

but i found only v.2.70
where Can I download OKHttpUtils Library version 2.8 ?

 

[DonManfred]

okhttputils is a internal library. It is installed when you install b4a. It is the file OkHttpUtils2.b4xlib in the internal library folder.

2.82 is the newest

make sure not to have a okhttputils2.xml and jar in your additional library folder.
