Android Api (Okhttps) not getting called in android 9(pie) and above

Issue

I am calling the android API in the same way as for other versions of phone and its working fine till Oreo version i.e. 8. But the API is not getting called in android 9 i.e. pie version and above. If there are some changes in pie, do let me know. Thanks in advance.

 private void getLoginAPI(String username, String password, String compnaycoce) {

    if (NetworkStatus.isNetworkConnected(this)) {
        LoginReqBean bean = new LoginReqBean();
        bean.UserId = username;
        bean.Password = password;
        bean.Company = compnaycoce;
        NetworkService serviceCall = new NetworkService(Constants.loginPost(), Constants.TAG_POST, this);
        serviceCall.call(bean);
    } else
        Toast.makeText(this, "Please check Internet connection", Toast.LENGTH_SHORT).show();
}

@Override
public void onNetworkCallInitiated(String service) {
    progressDialog = ProgressDialog.show(LoginActivity.this, "Info", "Validating Credentials, Please wait...");
    progressDialog.show();

}

 @Override
  public void onNetworkCallCompleted(String service, String response) {
    Log.e("LOGIN JSON ", "login " + response);

    if (progressDialog != null && progressDialog.isShowing())
        progressDialog.dismiss();

    LoginParentBean parentBean = LoginParentBean.fromJson(response);

    if (parentBean != null && parentBean.status) {
        LoginBean loginBean = parentBean.result;
        Toast.makeText(getApplicationContext(), "You Are logged in Successfully!", Toast.LENGTH_LONG).show();
        AppPreferences.INSTANCE.setUserID(loginBean.user_id);
        AppPreferences.INSTANCE.setUserRole(loginBean.userRole);
        AppPreferences.INSTANCE.setUserLocation(loginBean.location);
        AppPreferences.INSTANCE.setUserLocationID(loginBean.locationId);
        AppPreferences.INSTANCE.setIsPostGres(loginBean.isPostgres);
        AppPreferences.INSTANCE.setUserName(loginBean.username);
        AppPreferences.INSTANCE.setAccessToken(loginBean.tokenValue);
        AppPreferences.INSTANCE.setLogin(true);

        Intent intent = new Intent(getApplicationContext(), DashBoardActivity.class);
        startActivity(intent);
        finish();
    } else
        Toast.makeText(getApplicationContext(), "Please check your username and password again!", Toast.LENGTH_LONG).show();


}

@Override
public void onNetworkCallError(String service, String errorMessage) {
    if (progressDialog != null && progressDialog.isShowing())
        progressDialog.dismiss();

    MessageDialog msg = new MessageDialog(LoginActivity.this);
    msg.setButtonText("Ok");
    msg.show(getResources().getString(R.string.error_somethingwent), getResources().getString(R.string.app_name));
}
}

Solution

Android 6.0 introduced the useCleartextTraffic attribute under the application element in the android manifest. The default value in Android P is “false”. Setting this to true indicates that the app intends to use clear network traffic.

<application
    android:usesCleartextTraffic="true"

</application>

However, this may appear to fix the problem but it opens a threat to data integrity. A better solution is offered in Android 7.0 through network security configuration file
