}

Je ne vois pas de "onResume()" c'est volontaire ?

Lorsque des intent sont utilisés il faut faire ajouté une ligne avec les autres class extend activity dans le androidManifest voir lien ci-dessous:
https://forums.commentcamarche.net/forum/affich-26784030-intent-android

les logs suivant renvoient ils la valeur souhaitée dans le Logcat ?

Log.d("alerte", jour);
Log.d("alerte", mois);
Log.d("alerte", annee);
Log.d("alerte", patient);
Log.d("alerte", bouton);


Je regarde le code plus précisement ...

D'après le Log l'erreur provient de la fonction send

private void send(String jour, String mois, String annee, String patient, String bouton){
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("jour",jour));
nameValuePairs.add(new BasicNameValuePair("mois",mois));
nameValuePairs.add(new BasicNameValuePair("annee",annee));
nameValuePairs.add(new BasicNameValuePair("patient",patient));
nameValuePairs.add(new BasicNameValuePair("bouton",bouton));

try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.18.55.82/Android/patient.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
inputStream = entity.getContent();

}catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
}
}

Sur quel APi tu developpes ?
