我正在编写一个代码，用于从php api使用GCM获取推送通知。从PHP方面，我取得了成功，但在Android设备上我没有收到任何通知。这是我正在使用的代码
import java.util.Timer;
import java.util.TimerTask;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.PowerManager;
import android.util.Log;
import com.google.android.gcm.GCMBaseIntentService;
public class GCMIntentService extends GCMBaseIntentService {
private static final String TAG = "GCM Tutorial::Service";
// Use your PROJECT ID from Google API into SENDER_ID
public static final String SENDER_ID = "394127269050";
public GCMIntentService() {
super(SENDER_ID);
}
@Override
protected void onRegistered(Context context, String registrationId) {
Log.i(TAG, "onRegistered: registrationId=" + registrationId);
}
@Override
protected void onUnregistered(Context context, String registrationId) {
Log.i(TAG, "onUnregistered: registrationId=" + registrationId);
}
@Override
protected void onMessage(Context context, Intent data) {
String message;
// Message from PHP server
message = data.getStringExtra("message");
// Open a new activity called GCMMessageView
Intent intent = new Intent(this, GCMMessageView.class);
// Pass data to the new activity
intent.putExtra("message", message);
// Starts the activity on notification click
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
// Create the notification with a notification builder
Notification notification = new Notification.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setWhen(System.currentTimeMillis())
.setContentTitle("Android GCM Tutorial")
.setContentText(message).setContentIntent(pIntent)
.getNotification();
// Remove the notification on click
notification.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(R.string.app_name, notification);
{
// Wake Android Device when notification received
PowerManager pm = (PowerManager) context
.getSystemService(Context.POWER_SERVICE);
final PowerManager.WakeLock mWakelock = pm.newWakeLock(
PowerManager.FULL_WAKE_LOCK
| PowerManager.ACQUIRE_CAUSES_WAKEUP, "GCM_PUSH");
mWakelock.acquire();
// Timer before putting Android Device to sleep mode.
Timer timer = new Timer();
TimerTask task = new TimerTask() {
public void run() {
mWakelock.release();
}
};
timer.schedule(task, 5000);
}
}
@Override
protected void onError(Context arg0, String errorId) {
Log.e(TAG, "onError: errorId=" + errorId);
}
}
AndroidManifest Permissions
<android:name="com.example.pushex.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.example.pushex.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
你必须像这样创建一个广播接收器
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.WakefulBroadcastReceiver;
/**
* Created by rushabh on 1/9/15.
*/
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// Explicitly specify that GcmMessageHandler will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),
GcmMessageHandler.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
/* Intent i=new Intent(context,DialogActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);*/
}
}
复制此类
public class GcmMessageHandler extends IntentService {
String mes;
private Handler handler;
Context context = this;
String user;
PowerManager pm ;
String phn;
boolean isScreenOn;
public GcmMessageHandler() {
super("GcmMessageHandler");
}
SharedPreferences preferences;
SharedPreferences.Editor editor;
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
handler = new Handler();
pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
isScreenOn = pm.isScreenOn();
}
@Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
//get your message here
mes = extras.getString("your String");
user=extras.getString("your String");
//Show Your Local Notification
notification();
if (isScreenOn == false) {
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "MyLock");
wl.acquire(10000);
PowerManager.WakeLock wl_cpu = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyCpuLock");
wl_cpu.acquire(10000);
}
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
在 AndroidManifest 中声明它
<receiver
android:name=".GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.hmkcode.android.gcm" />
</intent-filter>
</receiver>
它为我工作
您是否在项目中添加了接收器类，清单中的接收器标签？
<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="example.demo.customer" />
</intent-filter>
</receiver>
<service android:name=".GCMIntentService" />
