How to deal with ERR_CLEARTEXT_NOT_PERMITTED error in Xamarin. It quite annoying. I average this error as shown below.

You are watching: Err_cleartext_not_permitted


The key driver behind this error is that it is avoiding the app to transmit and store data that need to be encrypted. This function was added starting with Android 9 (API level 28), cleartext support is disabled by default, and hence girlfriend will obtain this error message once you transmit data indigenous the app.

Essentially, you have actually 3-ish alternatives to remediate this issue. The fourth option is if you have actually a sanbox parameter.

OPTION #1Try making use of the “https://” instead of “http://”.Note the in htttp, over there is no data encryption implemented, when in the https conenction, the data room all encrypted through encryption algorithm.If the website you space accessing go not assistance https, then move on to option #2

OPTION #2Add this construction XML document in the complying with folder, res/xml/network_security_config.xml

* THIS could BE any type of URL that YOU desire TO permit CLEARTEXT TRANSMISSION

Add the parameter “android:networkSecurityConfig=”
xml/network_security_config” as presented below.For example if your, AndroidManifest.xml looks like presented below, add the network security configuration file as shown below.

OPTION #3Add the security parameter “android:usesCleartextTraffic=”true” as shonwn below.For example if your, AndroidManifest.xml watch like presented below, include the network defense configuration parameter as presented below.Note that choice #3 is much less secure than choice #2

You can discover the AndroidManifest.xml record as displayed in the folder below.

OPTION #4This is just applicable if you have a sandbox parameter.Reduce the sandbox variation to 1.The greater the sandbox version number, the greater the level that security. That is default value is 1; you have the right to also set it come 2. Setup this attribute to 2 switches the application to a various SELinux sandbox. The adhering to restrictions apply to a level 2 sandbox:The default worth of usesCleartextTraffic in the Network defense Config is false.
