是否有人在样本GCM服务器端和Android项目？ 最好一个教程，说明了一切。
我曾尝试看看纳入样本，但是我一直没能得到它的工作的一个。
我有一个C2DM项目，该项目是双向服务器端和Android，但我不知道如何将其转换为GCM。
我将使用GCM将邮件推
任何帮助，将不胜感激
Answer 1:
只要按照本教程
希望这会帮助你。
GCM服务器端（Java代码）
public class GCMServerJava {
/**
* @param args
*/
public static void main(String[] args) {
Sender sender = new Sender(enter your App id);// app id
Message message = new Message.Builder()
.collapseKey("1")
.timeToLive(3)
.delayWhileIdle(true)
.addData("message",
"this text will be seen in notification bar!!").build();
Result result;
try {
result = sender.send(message,"registration id which client get after registering device with google gcm service", 1);
System.out.println(result.toString());
Message message1 = new Message.Builder()
.build();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

请检查下面的代码GCM Android.This为我工作。
GCM的Android项目：
GCMIntentService.java
package com.example.samplegcm;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.google.android.gcm.GCMBaseIntentService;
public class GCMIntentService extends GCMBaseIntentService {
private static final String TAG = "GCMIntentService";
public GCMIntentService() {
super(CommonUtilities.SENDER_ID);
}
@Override
protected void onRegistered(Context arg0, String registrationId) {
Log.i(TAG, "Device registered: regId = " + registrationId);
}
@Override
protected void onUnregistered(Context arg0, String arg1) {
Log.i(TAG, "unregistered = " + arg1);
}
@Override
protected void onMessage(Context context, Intent intent) {
Log.i(TAG, "new message= ");
String message = intent.getExtras().getString("message");
generateNotification(context, message);
}
@Override
protected void onError(Context arg0, String errorId) {
Log.i(TAG, "Received error: " + errorId);
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
return super.onRecoverableError(context, errorId);
}
/**
* Issues a notification to inform the user that server has sent a message.
*/
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, PushAndroidActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
}
}
CommonUtilities的.java
package com.example.samplegcm;
public class CommonUtilities {
static final String SENDER_ID = "XXXXXXXXXXX"; // your project number from GCM
}
PushAndroidActivity.java
package com.example.samplegcm;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import com.google.android.gcm.GCMRegistrar;
public class PushAndroidActivity extends Activity {
private String TAG = "** pushAndroidActivity **";
private TextView mDisplay;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
checkNotNull(CommonUtilities.SENDER_ID, "SENDER_ID");
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
setContentView(R.layout.activity_main);
mDisplay = (TextView) findViewById(R.id.display);
final String regId = GCMRegistrar.getRegistrationId(this);
Log.i(TAG, "registration id ===== "+regId);
if (regId.equals("")) {
GCMRegistrar.register(this, CommonUtilities.SENDER_ID);
} else {
Log.v(TAG, "Already registered");
}
mDisplay.setText("Reg id is--> "+ regId);
}
private void checkNotNull(Object reference, String name) {
if (reference == null) {
throw new NullPointerException(
getString(R.string.error_config, name));
}
}
@Override
protected void onPause() {
super.onPause();
GCMRegistrar.unregister(this);
}
}
