Fix Cleartext Not Permitted Error in Android

Solve net::ERR_CLEARTEXT_NOT_PERMITTED Error in Android

This error started to appear presumably since android 8 or 9 updates, you can try these simple lines of codes in your android manifest file, remember to place it in the <Application of manifest file

 

 

What this line of code do is it approves the use cleartext traffic. So here is the code to fix android ERR_CLEARTEXT_NOT_PERMITTED Error

android:usesCleartextTraffic="true"

This will show API warning, to remove that warning, use the tools ignore  code, example:

android:usesCleartextTraffic="true"
tools:ignore="UnusedAttribute"

 

The total code should look like this

<application
    android:icon="@mipmap/ic_launcher"
    android:usesCleartextTraffic="true"
    android:label="@string/app_name"
    tools:ignore="UnusedAttribute"
    android:theme="@style/AppTheme">
...
 </application>

 

If this doesn’t fix your error, create a new network_security_config.xml file inside a folder named xml and paste this code in it:

<?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>

Now in your manifest application tag, add this code

android:networkSecurityConfig="@xml/network_security_config"

 

Example:

<application 
android:icon="@mipmap/ic_launcher" android:usesCleartextTraffic="true" android:label="@string/app_name"
android:networkSecurityConfig="@xml/network_security_config"
tools:ignore="UnusedAttribute" 
android:theme="@style/AppTheme"> ... 

</application>
