According to Network security configuration -
Starting with Android 9 (API level 28), cleartext support is disabled by default.
Also have a look at - https://koz.io/android-m-and-the-war-on-cleartext-traffic/
Codelabs explanation - https://codelabs.developers.google.com/codelabs/android-network-security-config/index.html
Option 1 -
First try hitting the URL with "https://" instead of "http://"
Option 2 -
Create file res/xml/network_security_config.xml -
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">api.example.com(to be adjusted)</domain>
</domain-config>
</network-security-config>
AndroidManifest.xml -
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:networkSecurityConfig="@xml/network_security_config"
...>
...
</application>
</manifest>
Option 3 -
android:usesCleartextTraffic Doc
AndroidManifest.xml -
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:usesCleartextTraffic="true"
...>
...
</application>
</manifest>
Also as @david.s' answer pointed out android:targetSandboxVersion can be a problem too -
According to Manifest Docs -
android:targetSandboxVersion
The target sandbox for this app to use. The higher the sandbox version number, the higher the level of security. Its default value is 1; you can also set it to 2. Setting this attribute to 2 switches the app to a different SELinux sandbox. The following restrictions apply to a level 2 sandbox:
The default value of usesCleartextTraffic in the Network Security Config is false.
Uid sharing is not permitted.
So Option 4 -
If you have android:targetSandboxVersion in <manifest> then reduce it to 1
AndroidManifest.xml -
<?xml version="1.0" encoding="utf-8"?>
<manifest android:targetSandboxVersion="1">
<uses-permission android:name="android.permission.INTERNET" />
