Question

Android

Messages are sent safely, reports come in, but when I try to send an HTML request setStatus("2", identificator); , then I get an error.

Answer 1

To start working with HTTP, it is desirable to make it a separate service.
Receivers register in onResume() and unregister in onPause()
To send SMS, you need to register permissions in the manifest and for TARGET API >= 23 make a request for their permission.
apparently runs in the main thread, hence the errors climb. You cannot interact with the network from the main thread. Call request(String sql) on a new thread.
