Question

有没有人有一个示例gcm服务器端和android项目？最好是一个解释所有内容的教程。

我试图查看样本中包含的那个但是我无法让它工作。

我有一个c2dm项目，它同时适用于服务器端和android，但我不知道如何将其转换为gcm。

我将使用gcm推送消息

任何帮助将不胜感激

Answer 1

按照此tutorial

进行操作希望它会对你有所帮助。

GCM SERVER-SIDE（java code）

  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();
    }
}

}

请查看下面的GCM Android代码。这对我有用。

GCM 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 .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);
    }
}
