Issue
I had created REST API on Spring Boot for my Android application, when I try to hit the API it works well in Postman but not in my application kindly help me out by looking to my code I shall be very thankful to the community members.
@RestController
@RequestMapping(value = USER_URL)
public class UserController {
private final UserService userService;
//email service
@Autowired
private EmailServiceImpl emailServiceImpl;
public UserController(UserService userService) {
this.userService = userService;
}
@PostMapping(value = LOGIN, consumes = MediaType.ALL_VALUE)
public ResponseEntity<Object> authenticateUser(@RequestParam(EMAIL) String email,
@RequestParam(PASSWORD) String password) {
if (userService.authenticateUser(email, password).size() > 0) {
//generating auth token
String token;
try {
token = MD5.getMD5Hex(email + DateTime.getCurrentTime(Constants.DATETIME.formatyyyyMMddHHmmss));
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
return ResponseHandler.negativeResponse(
HttpStatus.INTERNAL_SERVER_ERROR,
HttpStatus.INTERNAL_SERVER_ERROR.getReasonPhrase(),
"error generating auth token");
}
//adding authToken to users Entity
userService.updateUserAuthToken(email, token);
//sending response
return ResponseHandler.positiveResponse(
HttpStatus.OK,
HttpStatus.OK.getReasonPhrase(),
SUCCESS,
userService.authenticateUser(email, password).iterator().next(),
USER);
} else
return ResponseHandler.negativeResponse(
HttpStatus.NOT_FOUND,
HttpStatus.NOT_FOUND.getReasonPhrase(),
EMAIL_PASS_NOT_MATCH);
}

ERROR on application side It always hit onFailure I don't know what I'm doing wrong kindly help me out thanks
Solution
I had found that on android x you need to define network security configuration for this, you need to create an XML file in res->xml->network-security-config.xml here and mention this in your manifest
android:networkSecurityConfig="@xml/network-security-config"
network-security-config.xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">EXAMPLE.COM/API etc</domain>
</domain-config>
</network-security-config>
