Hi, I began using Google App Engine to create an Application Server for my
mobile application. I began by hosting PHPMyAdmin onto my Application
Server to manage my Google Cloud server following this link here:
https://cloud.google.com/sql/docs/phpmyadmin-on-app-engine. The problem is,
now I want to create a way for my Android Application to communicate with
my Application Server. I simply want to be able to store data into my
Application Server where I have hosted an instance of Google Cloud, and
also retrieve data from my instance of Google Cloud. However, I can't seem
to communicate with my application server at all. This is what I did after
following the above steps:
1. I created a Request Builder where I can send a Firebase Cloud Messaging
Token from my device to the Application Server like so:
public class NotificationInstanceService extends FirebaseInstanceIdService {
private static final String TAG = "NotificationInstance";
@Override
public void onTokenRefresh() {
//Getting registration token
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
//Displaying token on logcat
Log.d(TAG, "Refreshed token: " + refreshedToken);
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
//You can implement this method to store the token on your server
//Not required for current project
OkHttpClient client = new OkHttpClient();
//Create the request body
RequestBody body = new FormBody.Builder().add("Token", token).build();
//Know where to send the request to
Request request = new Request.Builder().url("<Application Server
URL>/register.php")
.post(body)
.build();
//Create
try {
client.newCall(request).execute();
} catch (IOException e) {
e.printStackTrace();
}
}
This seems to be working.
client.newCall(request.execute();
seems to go through without any errors.
1. I created a script called register.php which looks something like this:
if (isset($_POST["Token"])) {
$_uv_Token=$_POST["Token"];
$conn = mysqli_connect("/cloudsql/<database name url>","root","",
"FCM") or die("Error connecting");
$q="INSERT INTO users (Token) VALUES ( '$_uv_Token') "
." ON DUPLICATE KEY UPDATE Token = '$_uv_Token';";
var_dump(mysqli_query($conn,$q));
mysqli_query($conn,$q) or die(mysqli_error($conn));
mysqli_close($conn);
} else {
var_dump($_REQUEST);
}
This would be a simple way to connect to my database and update the users
database I created using the PHPMyAdmin console page.
3. After I created the script, I simply called
appcfg.py update .
in my directory, which I would assume redeploys my instance with
register.php created and I try to send my REST call via my Android
Application. I notice in the Google Cloud Console, logs are posted but I
don't see my data being uploaded to the users database. I am not sure where
I am going wrong. Any help would be much appreciated. Thanks!
