收到推送通知和未调用 CGM 意图服务时应用程序崩溃
App crash when receives push notification and CGM intent service not being called
一定是我做错了什么，但我是 android 工作室的新手，我找不到它。我有一个显示四个 webView 的应用程序，每个都在一个选项卡中，我正在尝试发送推送，json 响应代码没问题，但我在我的 GCM class 中建立了一些断点并且看起来它从未被调用过，并且我的应用程序在推送时崩溃 "arrives" 但没有显示任何推送通知。
json 响应代码：
{"multicast_id":4710708383941694704,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1431447972667924%e17d0a39f9fd7ecd"}]}{"registration_ids":["XxxxXXx"],"data":{"message":"New content available!"}}
这是我的 activity 主文件，当我有我的 GCM intent 服务时：
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
public class GcmIntentService extends IntentService {
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
public GcmIntentService() {
super("GcmIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
// The getMessageType() intent parameter must be the intent you received
// in your BroadcastReceiver.
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.
MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification("Deleted messages on server: " +
extras.toString());
// If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_MESSAGE.equals(messageType)) {
// This loop represents the service doing some work.
for (int i=0; i<5; i++) {
Log.i(TAG, "Working... " + (i+1)
+ "/5 @ " + SystemClock.elapsedRealtime());
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
}
}
Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
// Post notification of received message.
sendNotification("Received: " + extras.toString());
Log.i(TAG, "Received: " + extras.toString());
}
}
// Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
// Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(String msg) {
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, MainActivity.class), 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_logo_guias)
.setContentTitle("GCM Notification")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.setContentText(msg);

您的 GcmBroadcastReceiver 有问题。权限和类别错误。清单中的接收方条目应如下所示：
<receiver
android:name=".MainActivity$GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND"" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.example.alfredo.guiaswebtabapp" />
</intent-filter>
</receiver>
同时向接收器添加一个日志以检查它是否被调用。 GCM 消息触发接收方，然后接收方触发服务。
我有同样的错误，我通过在 public class GcmIntentService extends IntentService 内的 extras 添加一个过滤器来修复它，如下所示：
if(extras.getString("from").toString().equals(YOUR_SENDERID)){
sendNotification("Received: " + extras.toString(),extras);
Log.i("not an error received "+TAG, "Received: " + extras.toString());
}
else{
