hello, when I try to compile demo appHTTPClientDemo1 and it works
perfectly in android 6 but when I compile the apk for android 9 it
works but the GetAsync does not return data, response is empty.

Hello, good night in the version, nor do I remember Android 8 or 9
forward, the reading of url is disabled. For that you must manually
activate the activation.
You can make directly or create separate file below.
In the folder res /xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>

Modify in the ./AndroidManifest.xml file
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
   android:networkSecurityConfig="@xml/network_security_config">

That code

 <application    android:usesCleartextTraffic="true"

was suggested by the user SEGATOR my friend a while ago but I tried it
and somehow it didn't work for me. so I was doing the accesses with
synapse but since synapse does not have getasync segator it suggested
that I use jasynctask component but it is giving me application
blocking problems sometimes. With rest connections

so I am trying again to return to the jhttpclient component. see if it
works better with the rest server connections.
