问题 I am trying to follow the gcm tutorial from Googles docs. They say to call this method if Play Services are out of date: GooglePlayServicesUtil.getErrorDialog(resultCode, activity, 9000).show(); That's fine, but it puts a dialog that says "This app won't run unless you update Google Play Services" with an "Update" button. I want to change the title and the message text. My users CAN skip the update, and the app will still run. They just won't get push notifications. How do I change the

问题 I want to understand what is web-push and how can i use for my projects... Have found this example https://mobiforge.com/design-development/web-push-notifications But always getting an error when try to send notification via Firebase Cloud Messaging (FCM is the new version of GCM) {"multicast_id":6440031216763605980,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]} What it means "InvalidRegistration"?

问题 I have a java server running with the spring framework. For now I have to develop a GCM service to send data from the server to an Android app. I have been seeing some tutorial on Internet and all of them implements this service in a php script. I'm wondering if I can use them in my java server with spring. I know I can rewrite the code to Java but I don't have so much time as it's a work for University, so I don't wanna waste much time rewriting all of this.. So I'd like to know if it is

问题 The GCM Sample Project gives a stubbed out example of sending a GCM token to your server: public class RegistrationIntentService extends IntentService { ... @Override protected void onHandleIntent(Intent intent) { try { ... String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId), GoogleCloudMessaging.INSTANCE_ID_SCOPE, null); Log.i(TAG, "GCM Registration Token: " + token); // TODO: Implement this method to send any registration to your app's servers.

问题 I am trying to send a and read message payload using the google GCM mechanism. To send the data I am using the instructions found under "Web Push" in: https://developers.google.com/web/updates/2016/03/web-push-encryption?hl=en where it is instructed, that until full support by chrome is available, the payload can be sent using "raw_data" which needs to be base64 encripted. to display the data I am ussing chorome 50Beta, since it is supposed to support payloads. but when the 'push' event is

问题 I've read in Google Cloud Messaging documentation that GCM key is unique per device and per application. If I uninstall and reinstall the application the key is always the same, ie, the key is calculated based on some device and application identifiers or the key will change? 回答1: No, the key (called Registration ID) may change after you uninstall and re-install the app. The following scenario will cause the ID to change : un-install the app send a GCM message to the device several times,

问题 I recently added firebase messaging to my android app and I noticed some new permissions required to my app at similar time, for example: android.permission.READ_PHONE_STATE I couldn't find anywhere in documentation, why is this permission required. I even tried to explicitly disable it in manifest ( tools:node="remove" ) and messaging still works for me. It's kinda messy and I want to use only as few permissions as I need for sake of my users. Is this permissions really needed by messaging

问题 I've implemented GCM in my app, following this official tutorial. But my users under Android 4.0.3 reported me notifications are not working. I found out that onReceive from my GcmBroadcastReceiver extends BroadcastReceiver wasn't fired. Here is my Manifest. <!-- GCM --> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <uses-permission android:name="android.permission.VIBRATE" /> <permission
