Register Devices
Users need to be uniquely identified to receive push notifications.
Every user is assigned a unique device token that you can use to push it at any given time. Once the user has been assigned a device token, it should be stored in your application's backend database.
Please select your Android project type for the appropriate instructions:
Simply add the following blocking code to your application when you're ready to register the user for notifications:
String deviceToken = Pushy.register(getApplicationContext());val deviceToken = Pushy.register(applicationContext)This method returns a unique device token you can use to send notifications to this specific user's device.
Note: Pushy.register(Context) is a synchronous, blocking call, so make sure to only execute it from within a background thread (see code sample below).
Asynchronous Implementation
Add the following code to your application when you're ready to register the user for notifications:
if (!Pushy.isRegistered(this)) {
new RegisterForPushNotificationsAsync(this).execute();
}if (!Pushy.isRegistered(this)) {
RegisterForPushNotificationsAsync(this).execute()
}
Copy the following RegisterForPushNotificationsAsync() async implementation and modify it accordingly to send device tokens to your backend server.
private class RegisterForPushNotificationsAsync extends AsyncTask<Void, Void, Object> {
Activity mActivity;
public RegisterForPushNotificationsAsync(Activity activity) {
this.mActivity = activity;
}
protected Object doInBackground(Void... params) {
try {
// Register the device for notifications
String deviceToken = Pushy.register(getApplicationContext());
// Registration succeeded, log token to logcat
Log.d("Pushy", "Pushy device token: " + deviceToken);
// Send the token to your backend server via an HTTP GET request
new URL("https://{YOUR_API_HOSTNAME}/register/device?token=" + deviceToken).openConnection();
// Provide token to onPostExecute()
return deviceToken;
}
catch (Exception exc) {
// Registration failed, provide exception to onPostExecute()
return exc;
}
}
@Override
protected void onPostExecute(Object result) {
String message;
// Registration failed?
if (result instanceof Exception) {
// Log to console
Log.e("Pushy", result.toString());
// Display error in alert
message = ((Exception) result).getMessage();
}
else {
message = "Pushy device token: " + result.toString() + "\n\n(copy from logcat)";
}
// Registration succeeded, display an alert with the device token
new android.app.AlertDialog.Builder(this.mActivity)
.setTitle("Pushy")
.setMessage(message)
.setPositiveButton(android.R.string.ok, null)
.show();
}
}class RegisterForPushNotificationsAsync(activity: Activity) : AsyncTask<Void, Void, Any>() {
var activity: Activity = activity;
override fun doInBackground(vararg params: Void): Any {
try {
// Register the device for notifications
val deviceToken = Pushy.register(activity)
// Registration succeeded, log token to logcat
Log.d("Pushy", "Pushy device token: " + deviceToken)
// Send the token to your backend server via an HTTP GET request
URL("https://{YOUR_API_HOSTNAME}/register/device?token=" + deviceToken).openConnection()

return deviceToken
} catch (exc: Exception) {
// Registration failed, provide exception to onPostExecute()
return exc
}
}
override fun onPostExecute(result: Any) {
var message: String
// Registration failed?
if (result is Exception) {
// Log to console
Log.e("Pushy", result.message)
// Display error in alert
message = result.message.toString()
}
else {
// Registration success, result is device token

}
