How enable clear text traffic on Android 9
The update from Android PIE we come across the error ERR_CLEARTEXT_NOT_PERMITTED. To resolve it is necessary to allow unencrypted traffic. To enable all IPS, follow the steps below.
Resolve on native Android:
Access to app/src/main/res/xml/network_security_config.xml
and replace for this code.
<?xml version=”1.0" encoding=”utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted=”true” />
</network-security-config>
After edit file go to AndroidManifests.xml and add:
<application
android:name=".core.App"
android:networkSecurityConfig="@xml/network_security_config"
android:allowBackup="true"
...
Resolve on Ionic:
Access to config.xml
and add this code:
...
<platform name="android">
<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">
<application android:usesCleartextTraffic="true" />
</edit-config>
...
</platform>
<platform name="ios">
...
After change config.xml, go to resources/android/xml/network_security_config.xml
and replace for this code:
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
</network-security-config>
Start an ionic build, after finishing make sure platform/android/app/src/res/xml/network_security_config
` is enabled clear text traffic. Must be like the file below:
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
</network-security-config>
Enable to specific IP:
Replace the file network_security_config.xml
(file path mentioned above), by the code below.
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">localhost</domain>
<domain includeSubdomains="true">10.1.27.25</domain>
</domain-config>
</network-security-config>
