GCM推送通知实施

Question

我似乎在使用我的应用程序中的基本GCM包实现推送通知时遇到了麻烦。 我已经尝试了几个教程，并且到目前为止还无法使其正常工作。

我希望也许我可以得到一些帮助，当我从Ubuntu服务器发送时，我没有收到任何通知。

主要活动

 import android.app.Activity; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.net.Uri; import android.os.AsyncTask; import android.os.Bundle; import android.support.v7.app.ActionBarActivity; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import com.google.android.gms.gcm.GoogleCloudMessaging; import com.google.android.gms.iid.InstanceID; import java.io.IOException; import java.net.HttpURLConnection; import java.net.URL; public class MainActivity extends ActionBarActivity { private String RegID = ""; private Context context = null; private GoogleCloudMessaging gcm = null; private InstanceID instanceID = null; private BroadcastReceiver mHandleMesageReceiver; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); context = getApplicationContext(); if(RegID.isEmpty()) { register RegInBG = new register(); RegInBG.execute("e"); post task = new post(); task.execute(RegID); mHandleMesageReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { } }; } } /*Runnable task to be used to register app in the GCM service for push notifications, made by Devin Adams */ public class register extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... params) { try { if (instanceID == null) { instanceID = InstanceID.getInstance(context); } if (gcm == null) { gcm = GoogleCloudMessaging.getInstance(context); } RegID = instanceID.getToken(getString(R.string.sender_id), gcm.INSTANCE_ID_SCOPE, null); Log.e("***********", "************"); Log.e("***********", "************"); Log.e("RegID", RegID); Log.e("***********", "************"); Log.e("***********", "************"); } catch (IOException ex) { Log.e("***********", "************"); Log.e("***********", "************"); Log.e("Error", ex.getMessage()); Log.e("***********", "************"); Log.e("***********", "************"); } return "sd"; } } public class post extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... params) { try { String tempurl = getString(R.string.server_url); Uri.Builder b = Uri.parse(tempurl).buildUpon(); String url = b.build().toString(); HttpURLConnection connection = (HttpURLConnection) ((new URL(url))).openConnection(); connection.setRequestMethod("POST"); connection.setDoInput(true); connection.setDoOutput(true); connection.connect(); connection.getOutputStream().write((params[0]).getBytes()); connection.disconnect(); } catch (IOException ex) { Log.e("Error", ex.getMessage()); } return "getg"; } } } 

MyGcmListener

 import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.media.RingtoneManager; import android.net.Uri; import android.os.Bundle; import android.support.v4.app.NotificationCompat; import android.util.Log; import com.google.android.gms.gcm.GcmListenerService; public class MyGcmListener extends GcmListenerService { private static final String TAG = "International Studies"; @Override public void onMessageReceived(String from, Bundle data) { String message = data.getString("message"); Log.d(TAG, "From: " + from); Log.d(TAG, "Message: " + message); Log.e("Message", "received "); sendNotification(message); } private void sendNotification(String message) { Intent intent = new Intent(this, MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT); Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_launcher) .setContentTitle("International Studies") .setContentText(message) .setAutoCancel(true) .setSound(defaultSoundUri) .setContentIntent(pendingIntent); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(0, notificationBuilder.build()); } } 

MyGcmMessageHandler

 import android.app.IntentService; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.widget.Toast; import com.google.android.gms.gcm.GoogleCloudMessaging; import java.lang.Runnable; import java.util.logging.Handler; import java.util.logging.LogRecord; public class MyGCMMessageHandler extends IntentService { String mes; private Handler handler; public MyGCMMessageHandler() { super("MyGCMMessageHandler"); } public void onCreate() { super.onCreate(); this.handler = new Handler() { @Override public void close() { } @Override public void flush() { } @Override public void publish(LogRecord record) { } }; } protected void onHandleIntent(Intent intent) { Bundle extras = intent.getExtras(); GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this); String messageType = gcm.getMessageType(intent); this.mes = extras.getString("title"); this.showToast(); Log.i("GCM", "Received: (" + messageType + ") " + mes); MyGCMReceiver.completeWakefulIntent(intent); } public void showToast() { this.handler.post(new Runnable() { @Override public void run() { Toast.makeText(MyGCMMessageHandler.this.getApplicationContext(), MyGCMMessageHandler.this.mes, Toast.LENGTH_LONG).show(); } }); } } 

推送脚本使用python-gcm运行

from gcm import *
gcm = GCM("")
data = {'message': 'This is a test push', 'param2': 'value2'}
reg_id = ''
gcm.plaintext_request(registration_id=reg_id, data=data)

GCM中填充了API密钥，并在此应用程序中注册了我的手机的reg_id。

谁能帮我吗？ 我无法弄清楚出了什么问题。

编辑：清单。

Answer 1

问题1：您的AndroidManifest.xml设置错误。 这条线应该改变。

<category android:name="gcm.play.android.samples.com.gcmquickstart" /> 

gcm.play.android.samples.com.gcmquickstart应该用您自己的包替换。

问题2：您输入错误。

import java.util.logging.Handler;

不是你想要的。 需要的是android.os.Handler

Handler有两个主要用途：（1）安排消息和runnables作为未来某些点执行; （2）将要在不同于自己的线程上执行的操作排入队列。
