Android Push Notification (GCM), is there any Daily Limit?

Is there any daily limit for number push notifications (GCM) can be sent to a particular android application user?

Solution 1:

Update: GCM is deprecated, use FCM

After Google replaced C2DM with GCM, they took off all limits.

SOURCE: http://developer.android.com/google/gcm/c2dm.html#history

Prior to GCM (when it was still called C2DM): https://developers.google.com/android/c2dm/#limitations)

The only limits you run into the GCM documentation is this: http://developer.android.com/google/gcm/adv.html#lifetime

Quote from the above link:

Note: There is a limit on how many messages can be stored without collapsing. That limit is currently 100. If the limit is reached, all stored messages are discarded. Then when the device is back online, it receives a special message indicating that the limit was reached. The application can then handle the situation properly, typically by requesting a full sync.

I am not sure if this is relevant to your question though.

Solution 2:

There is a limit of 1000 notifications at one go.

Assume you have 50000 regids. You cannot send all 50000 together. After the first 1000, you will have to separately select the next 1000 and so on.
