How to allow all Network connection types HTTP and HTTPS in Android (9) Pie?

The easy way to implement this is to use this attribute to your AndroidManifest.xml where you allow all http for all requests:

<application android:usesCleartextTraffic="true">
</application>

But in case you want some more configurations for different links for instance, allowing http for some domains but not other domains you must provide res/xml/networkSecurityConfig.xml file.

To do this in Android 9 Pie you will have to set a networkSecurityConfig in your Manifest application tag like this:

<?xml version="1.0" encoding="utf-8"?>
<manifest ... >
    <application android:networkSecurityConfig="@xml/network_security_config">




    </application>
</manifest>

Then in your xml folder you now have to create a file named network_security_config just like the way you have named it in the Manifest and from there the content of your file should be like this to enable all requests without encryptions:

<?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>

From there you are good to go. Now your app will make requests for all types of connections. For additional information on this topic read here.

The FULLY WORKING SOLUTION for both Android or React-native users facing this issue just add this android:usesCleartextTraffic="true" in AndroidManifest.xml file like this:

android:usesCleartextTraffic="true"
tools:ignore="GoogleAppIndexingWarning">
<uses-library
    android:name="org.apache.http.legacy"
    android:required="false" />

in between <application>.. </application> tag like this:

<application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:allowBackup="false"
      android:theme="@style/AppTheme"
        android:usesCleartextTraffic="true"
        tools:ignore="GoogleAppIndexingWarning">
        <uses-library
            android:name="org.apache.http.legacy"
            android:required="false" />
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"/>
 </application>
