Http get dont work

I do not get the http get from the last update of the security patch of android in mobile phones

Can you elaborate? It’s not clear what you are asking.

recently in some phones the android security patch was updated, and since then the http get requests do not work in those devices, in which the patch has not been updated, the get requests continue to work

Are you using http or https?
From Android 9, Android blocks http requests by default, not sure if that security patch also does the same for older Android versions.

So if using http you’ll have to move to https, but as workaround you can disable this policy by adding this in the application tag of the AndroidManifest.xml android:usesCleartextTraffic="true".

If using https, then no idea of what’s going on, but might be some certificate on the server that was vulnerable and not allowed by the security update.

I have added this tag, but i still have same error
