How to restore the registration identifier and send a message to a third-party application in android c2dm0 +

Question

The sender ID used in the registration process for c2dm.but does not have a receipt message or any register identifier.

// Akashc2dmActivity.java file

public class Akashc2dmActivity extends Activity implements OnClickListener { Button Register,id; private static PowerManager.WakeLock mWakeLock; private static final String WAKELOCK_KEY = "C2DM_LIB"; @Override protected void onCreate(Bundle savedInstanceState) { if (mWakeLock == null) { PowerManager pm = (PowerManager) Akashc2dmActivity.this .getSystemService(Context.POWER_SERVICE); mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, WAKELOCK_KEY); } super.onCreate(savedInstanceState); setContentView(R.layout.main); Register = (Button) findViewById(R.id.button); Register.setOnClickListener(this); } public void sendRequest(View ignored) { Log.d("Register", "hello"); Intent registrationIntent = new Intent(Constants.SEND_REGISTRATION_TO_GOOGLE); iHaveNoClueWhatThisSettingDoesButItIsRequiredForTheIntentToWorkSoIBetterSetIt(registrationIntent); registrationIntent.putExtra("sender", Constants.C2DM_APPLICATION_SERVER_ID); startService(registrationIntent); } private void iHaveNoClueWhatThisSettingDoesButItIsRequiredForTheIntentToWorkSoIBetterSetIt(Intent registrationIntent) { registrationIntent.putExtra("app", PendingIntent.getBroadcast(Akashc2dmActivity.this, 0, new Intent(), 0)); Log.d("app", ""+PendingIntent.getBroadcast(Akashc2dmActivity.this, 0, new Intent(), 0)); } @Override public void onClick(View v) { if(v == Register){ sendRequest(Register); } }

and finally use the manifest file

please tell me how to get the register ID and send a massage of a third-party application to c2dm

Answer 1

The code code works successfully there. There are some changes in the C2DMBroadcastReceiver.java class to receive a message and there is a MessageClass.java class to add a message to the server

File C2DMBroadcastReceiver.java

 public class C2DMBroadcastReceiver extends BroadcastReceiver { NotificationManager nm; @Override public final void onReceive(Context context, Intent intent) { if (Constants.RECEIVED_REGISTRATION_ID_FROM_GOOGLE.equals(intent.getAction())) { Log.d(Constants.TAG, "Received a registration ID from Google."); intent.setAction(Constants.REGISTRATION_INTENT); intent.setClassName(context, RegistrationIDReceiver.class.getName()); } else if (Constants.RECEIVED_C2DM_MESSAGE_FROM_GOOGLE.equals(intent.getAction())) { Function_notification(context,intent); Log.d(Constants.TAG, "Received a C2DM message from Google."); intent.setAction(Constants.START_C2DM_SERVICE); intent.setClass(context, C2DMService.class); } context.startService(intent); } private void Function_notification(Context context,Intent intent ) { Bundle extras = intent.getExtras(); Log.d("extras",""+extras); String message2 = (String)extras.get("collapse_key"); Log.d("collapse_key","collapse_key=" + message2); String message1 = (String)extras.get("payload"); Log.d("extras","payload=" + message1); String error = intent.getStringExtra("error"); Log.d("extras","error=" + error); nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); CharSequence from = "Please Testing for Recive message"; CharSequence message = message1; Intent notifyintent = new Intent(context,Akashc2dmActivity.class); PendingIntent contentIntent = PendingIntent.getActivity(context, 0,notifyintent, 0); Notification notif = new Notification(R.drawable.icon,"Please take your Recive message", System.currentTimeMillis()); notif.setLatestEventInfo(context, from, message, contentIntent); nm.notify(1, notif); } } > **Add This class in com.technosoft.C2dm_Server_1 package** 

MessageClass.java file

 public class MessageClass { public static final String PARAM_REGISTRATION_ID = "registration_id"; public static final String PARAM_DELAY_WHILE_IDLE = "delay_while_idle"; public static final String PARAM_COLLAPSE_KEY = "collapse_key"; private static final String UTF8 = "UTF-8"; public static String sendMessage(String auth_token, String registrationId, String message) throws IOException { StringBuilder postDataBuilder = new StringBuilder(); postDataBuilder.append(PARAM_REGISTRATION_ID).append("=") .append(registrationId); postDataBuilder.append("&").append(PARAM_COLLAPSE_KEY).append("=") .append("1"); postDataBuilder.append("&").append("data.payload").append("=") .append(URLEncoder.encode("hello", UTF8)); byte[] postData = postDataBuilder.toString().getBytes(UTF8); // Hit the dm URL. URL url = new URL("https://android.clients.google.com/c2dm/send"); HttpsURLConnection .setDefaultHostnameVerifier(new CustomizedHostnameVerifier()); HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setDoOutput(true); conn.setUseCaches(false); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8"); conn.setRequestProperty("Content-Length", Integer.toString(postData.length)); conn.setRequestProperty("Authorization", "GoogleLogin auth=" + auth_token); OutputStream out = conn.getOutputStream(); out.write(postData); out.close(); int responseCode = conn.getResponseCode(); if (responseCode == 401 || responseCode == 403) { // The token is too old - return false to retry later, will // fetch the token // from DB. This happens if the password is changed or token // expires. Either admin // is updating the token, or Update-Client-Auth was received by // another server, // and next retry will get the good one from database. Log.d("C2DM", "Unauthorized - need token"); } String updatedAuthToken = conn.getHeaderField("Update-Client-Auth"); if (updatedAuthToken != null && !auth_token.equals(updatedAuthToken)) { Log.d("C2DM", "Got updated auth token from datamessaging servers: " + updatedAuthToken); sendMessage(updatedAuthToken,registrationId, message); } String responseLine = new BufferedReader(new InputStreamReader( conn.getInputStream())).readLine(); // NOTE: You *MUST* use exponential backoff if you receive a 503 // response code. // Since App Engine task queue mechanism automatically does this // for tasks that // return non-success error codes, this is not explicitly // implemented here. // If we weren't using App Engine, we'd need to manually implement // this. if (responseLine == null || responseLine.equals("")) { Log.i("C2DM", "Got " + responseCode + " response from Google AC2DM endpoint."); throw new IOException( "Got empty response from Google AC2DM endpoint."); } String[] responseParts = responseLine.split("=", 2); if (responseParts.length != 2) { Log.e("C2DM", "Invalid message from google: " + responseCode + " " + responseLine); throw new IOException("Invalid response from Google " + responseCode + " " + responseLine); } if (responseParts[0].equals("id")) { Log.i("Tag", "Successfully sent data message to device: " + responseLine); } if (responseParts[0].equals("Error")) { String err = responseParts[1]; Log.w("C2DM", "Got error response from Google datamessaging endpoint: " + err); // No retry. throw new IOException(err); } return responseLine; } private static class CustomizedHostnameVerifier implements HostnameVerifier { public boolean verify(String hostname, SSLSession session) { return true; } } 

}

**This class use in RegistrationIDRegistrar.java class**

File RegistrationIDRegistrar.java

 class RegistrationIDRegistrar { static final String MASHMOBILE_C2DM_SERVER_URL = "http://10.0.1.3:8888"; String response; private RegistrationIDRegistrar(String url) { } void registerIdWithC2DMService(final String registrationId){ //getAuthentification(); Log.d("registrationId", ""+registrationId); try { String auth_key =getToken(Constants.C2DM_APPLICATION_SERVER_ID,Constants.C2DM_APPLICATION_SERVER_Password); Log.d("auth_key", ""+auth_key); response = MessageClass.sendMessage(auth_key,registrationId, "hello test android"); Log.d("Response code", ""+response); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public static String getToken(String email, String password) throws IOException { // Create the post data // Requires a field with the email and the password StringBuilder builder = new StringBuilder(); builder.append("Email=").append(email); builder.append("&Passwd=").append(password); builder.append("&accountType=GOOGLE"); builder.append("&source=MyLittleExample"); builder.append("&service=ac2dm"); // Setup the Http Post byte[] data = builder.toString().getBytes(); URL url = new URL("https://www.google.com/accounts/ClientLogin"); HttpURLConnection con = (HttpURLConnection) url.openConnection(); con.setUseCaches(false); con.setDoOutput(true); con.setRequestMethod("POST"); con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); con.setRequestProperty("Content-Length", Integer.toString(data.length)); // Issue the HTTP POST request OutputStream output = con.getOutputStream(); output.write(data); output.close(); // Read the response BufferedReader reader = new BufferedReader(new InputStreamReader( con.getInputStream())); String line = null; String auth_key = null; while ((line = reader.readLine()) != null) { if (line.startsWith("Auth=")) { auth_key = line.substring(5); Log.d("auth_key", ""+auth_key); } } // Finally get the authentication token // To something useful with it return auth_key; } static RegistrationIDRegistrar getInstance() { return new RegistrationIDRegistrar(MASHMOBILE_C2DM_SERVER_URL); } } 

Answer 2

File C2DMBroadcastReceiver.java

 if (Constants.RECEIVED_REGISTRATION_ID_FROM_GOOGLE.equals(intent.getAction())) { //here you can get registration id final String registrationId = intent .getStringExtra("registration_id"); /*your code*/ } 

and then call the registerIdWithC2DMService(registrationId) method from the RegistrationIDRegistrar class.
